F rank Hiob A DISSERTATION Submitted to Michigan State University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY Department of Secondary Education 1978 ABSTRACT DEVELOPMENT AND PILOT TESTING OF A SELF INSTRUCTIONAL MANUAL FOR THE DESIGN OF LEARNING MODULES: A RESEARCH AND DEVELOPMENT STUDY By P. Frank Hiob In spite of widespread use of self instructional materials and a plethora of books and manuals on how to develop such materials, it was not known whether a self instructional manual could be used to enable college level instructors with very little background in instructional design to produce self instructional modules which involved higher level cognitive skills. To answer this question the author designed and tested a self instructional manual . Six college level instructors were asked to design modules using the cognitive skills and step by step guidance provided by the Manual. These instructors received no additional formal instruction regarding module design. The completed modules were evaluated on a criterion- referenced evaluation form by six evaluators. All six modules reached the criterion level suggesting that the‘ Manual was effective as a learning experience. The designers were positive about their experience. However, all designers indicated that they required additional outside information to fully complete their modules. DEDICATION This dissertation is dedicated to my Mother and late Father. ii ACKNOWLEDGEMENTS I wish to acknowledge my indebtedness to Dr. A. Abedor, Chairman of my Committee for the support, advice and guidance which he so readily and competently provided. Other members of my Committee, Dr. R. Farace, Dr. C. Gentry and Professor B. Wenberg all provided excellent assistance in their own particular ways and to each I am grateful. The help and steadfast support provided by Professor Wenberg goes much further than her involvement on my Committee, and includes continuous support and, through a graduate assistantship, an inspired introduction to what was to me a whole new field of Dietetics. A number of people have made important contributions in one way or another: the designers who produced modules in Australia and Hawaii, Mary Jo Morrissey for her module, Dr. Walter Dick of Florida State University for permission to use various materials, the Dietetic Faculty at Michigan State University for form atively evaluating the Manual and suggesting improvements. To my wife Elizabeth for her love and help over the last three years I owe much of this work. iii TABLE OF CONTENTS LIST OF TABLES O O O O O O O O O O O O O O O O O LISTOFFIGURES................

Subject Area The subject area for this dissertation is instructional design, educational systems and educational technology. The major focus is the design of self instructional programs in higher education, particularly where higher level cognitive skills1 are required. B. Statement of Problem In the area of Dietetic Education (as in a number of other professionSQ) the national controlling body has called for an improve- ment in the educational preparation of its pre-service students (Study Commission, American Dietetic Association, 1972). The term "higher level cognitive skills" refers to those skills which on Gagne's learning hierarchies (1977) are designated as "rule" or "problem solving". Medical Education is another example, see A Handbook for Change, Recommendations of the Joint Comm ittee on Medical Education. Wm . F. Fell Co. Philadelphia, Pennsylvania, 1972. 1 Part of the concern is the level at which subject matter is currently being taught. Cox (1970) found that the cognitive level at which the average college level instructor teaches is at the comprehension level on Bloom's (1956) taxonomy, a low level with reliance mainly on memory. Instructors claim (Cox, 1965, 1970) that they expect their college students to operate at a much higher level such as problem solving, where a number of concepts and principles are combined to reach a solution to a complex problem . This problem is fully discussed in the Manual (Appendix D). In response to the challenge to improve the quality of education various innovative programs are being established throughout the country. At Michigan State University, on advice from the University's Learning and Evaluation Service, and funded by a Kellogg grant, a Competency Based Education (CBE) Program 1 has been initiated in the Department of Food Science and Human Nutrition. 1 The implied characteristics of CBE are: 1 . Instruction is individualized and personalized. 2. The learning experience of the individual is guided by feedback. 3. The program as a whole is systematic. 4. The emphasis is on exit, not entrance, requirements. 5. Instruction is modularized. W. Robert Houston, "Competency Based Education" in Houston, W.R. , Exploring Competengy Based Education, McCutchan Publishing Corp. , Berkeley, 1974. 3 One feature of CBE is that it requires instruction to be individualized and presented through modules. Individualized instruction finrough modules has become the fastest growing movement in education (Novak, 1973; Cross, 1976; Vermilye, 1976). The use of modules is also central in all other methods of improving education through individualization (Goldscrmid, 1974). For instructors to fully participate in CBE or any plan of individualized instruction, it will be necessary for them to be able to design modules as only rarely will finey find suitable modules avail able for purchase. The task of designing modules should be recognized as requir- ing a great deal of knowledge on learning, teaching, educational materials, fine specification of learning outcomes, analysis of content, an understanding of fine interrel atedness of parts of a learning system, and the cybernetic1 nature of an instructional system . Most of this knowledge is new to university instructors wifinout an education background (Chase, 1968; Cl ark and HOpkins, 1969; Gideons, 1970). There are texts available on fine design of modules but they usually require a workshop, prior experience, or an intensive period of training, e.g. , System Approach for Educatiog, (Corrigan Cybernetic is taken to mean control through feedback. Von Bertal anffy's (1966) explanation of the cybernetic system is presented on p. 4 et al , 1969). Self instructional manuals on modular instruction are available, e.g. Criterion Referenced Instruction (Mager, 1961). Unfortunately finere is no research study finat provides evidence that useful modules actually result from working through a manual without additional intervention. As Branson (1978) points out, it may even be impossible to find a generic, all purpose manual or model to suit fine specific needs and target population of a particular program . Given fine realities of constraints on instructors' time, and an understandable reluctance to "go back to school", one alternative would be a self instructional manual on the design of modules developed for a particular population and with its needs in mind. Up to now the identification of need has been on a macro level. The target population at such a level is diverse, and according to Branson (1978) it would be unlikely that a model could be devised that adequately meets the needs of such a heterogeneous group. Consequently, it is necessary to look at the micro level in order to determine the needs of a more homogeneous group. Such a focus would be more specific in identifying needs, and it would be more likely that these specific needs could be met. The population at the micro level for this dissertation is the Co-ordinated Undergraduate Program in Dietetics at MSU . In 1974, MSU was awarded a grant by the Kellogg Foundation to develop a co-ordinated undergraduate program in Dietetics. In its proposal for the grant, MSU stated that it would develop the program along the lines of a competency based education system . Subsequently a committee, designated as DURC1, began to work to bring about a CBE program . So as not to interupt fine flow of finis General Introduction, the proceedings of the Committee's work are stated in Appendix F. The pertinent aspect of DURC was a difficulty the committee experienced in accepting highly conceptual new ideas concerning Competency Based Education. It was stated by the Committee that actual examples of CBE concepts were necessary if progress was to be made. Given fine articulated need for knowledge on CBE concepts and a need for actual examples of modules, fine aufinor decided that there was a need for a manual which would attempt to meet finese two needs. To the author fine major problems appeared to be: a. On the part of some key faculty members there was a rejection of rigid CBE methodology which finey equated with behavioral ism . These faculty looked for a less rigid program Dietetic Undergraduate Resource Committee. 6 which would accomodate their concerns. For example, they refiJsed to participate in an early step of fine CBE program (that of sequencing competencies) by stating that it was not possible to sequence competencies when competencies had not and could not be adequately determined through fine use of a Magerian formula. Their concern is often expressed in literature (Eisner, 1975; Elam, 1972; Neff, 1975; Ainswortln, 1977) b'. For a number of faculty, particularly finose heavily engaged in research, the concepts of CBE were quite novel. They held an Open mind to a program which would improve learning, but did not have sufficient information on CBE to become committed to the program . c . Lack of concrete exam pl es of what the innovation (CBE) was all about led to a great deal of uncertainty. The commonly used term "module", which was chosen by DURC as fine unit of instruction in CBE and finerefore a key concept, was perceived by many as threatening . C. Statement of Need Given the above problems, the author, after consulting with a number of people from DURC, decided finat the major needs in which he could have some impact were: 1 . To modify fine CBE concepts so finat they responded to the needs and aspirations of the target population; thereby being perceived as rewarding and consequently accepted. 7 2 - The dissemination process of the acceptable CBE concepts through a product. Concrete evidence should be produced to make CBE concepts visible. 3. The product referred to in (2) should be a module as modules are central to CBE (Houston, 1974). 4. The acceptable CBE concepts, and how to translate these concepts into a module, shOuld be presented through a manual So as to be convenient and fit wifinin faculty assumed method of information assimilation. 5. The manual should address the needs expressed (on pp. 1-6) under Statement of Problem . For example, it should deal with higher order cognitive learning rather than lower level information Skills. Given this background the author decided to develop a manual to address finese needs. That such a manual would be effective became fine focus of interest in the present pilot study. D . Research Questions There are two major research questions to be addressed in this pilot study. First, can a self instructional manual on designing modules be developed where those who conn pl ete the manual reach mastery level on its contents? Second, will attainment of mastery of the self instructional manual result in a module which meets some minimum acceptable standards? There is also a third question: will the module so developed obtain results at least as good as those obtained through traditional methods of instruction? Because of the time required it is unlikely that such data can be obtained. Furthermore, a number of uncontrollable factors could bias such data. Therefore, data related to this third question will be considered as additional supporting evidence rather than the primary focus of finis dissertation. The following are stipulations to the research question: a. The designer of the module will be a faculty member in higher education in a field other than education and will have had very little formal training in education. b. The learning outcomes of fine modules must include higher order cognitive skills; on Gagne's (1975) classification they need to reach at least defined concept level or higher. c. The designers of modules will need to be in geographic locations different from that of the authOr so as to control for possible aufinor input. E . Limitations of the Study The following limitations reduce the general izabil ity of this pilot study. The major limitation is the relatively small number of modules avail able for evaluation. One reason for fine small number is fine tremendous amount of work involved in 9 developing a module. A conservative estimate is finat the design takes somefining like 100 hours. On top of this is time taken for developing materials (e.g. , if the module is on PLATO, it may take another 100 hours to develop the PLATO program). For the self instructional manual to be mastered and a module produced may take six months. The estimates stated in this paragraph are based on the author's own experience in developing and testing the module RENAL which is on Control Data Corporation's PLATO systems . House (1974) gives an account of his experiences in developing modules on PLATO; his experiences parallel those of the author1 . Another limitation is the lack of controls because fine modules will be developed independently of the author, without his involvement. Thus factors which cannot be controlled in this study include: a) fine variability of fine learner/designer entry skills, b) the input from fine designer's environment in addition to the Manual, and c) ensuring that the designer proceed through the Manual correcting his/her own embedded tests which dictate progress or remediation. There are no effective controls or way of monitoring this process; if fine designer does not reach mastery on a test, will he/she in fact go through fine materials again as required, or continue wifin the next Rosinski (1977) gives an account of fine difficulties in recruit- ing faculty to develop modules even when an honorarium was offered-~the anticipated number of modules went down from from twenty five to just one. 10 step in the manual? In other words, there are no effective controls which allow only finose who have mastered the manual to proceed on to the design stage. While these limitations are significant, it is felt that for purposes of the present pilot study finey must be tolerated since further studies will lead to refinement. CHAPTER 11 REVIEW OF LITERATURE O rgani zation The review of literature is divided into two sections. The first deals with some critical observations on literature on the design of instruction. The second addresses research findings pertinent to the choices made in designing the Manual, with a concluding review on the diffusion of educational innovations. A. Critical Observations on Literature Review The review of literature on self instructional manuals is a complex task. Part of fine complexity is fine abundance of idiosyn- cratic, loosely defined terminology. For example, self instructional manuals are referred to by a variety of alternative appelations includ- ing: Systems Engineering and Training (SET), Learning Systems Design (LSD), the Systematic Design of Instruction (SDI), Systems Approach 11 to Training (SAT), Personalized Instruction (PI), Instructional Systems Development (ISD), just to mention a few. In this disse rtation the acronymn SAT (for Systems Approach to Training) will be used to represent self-instructional manuals . Differences between the manuals range from super- ficial variations in terminology to fundamental variations in philosophy. A basic issue on which disagreement exists is the degree to which the instructional design process can be reduced to a linear sequence of generally applicable, prescriptive procedures. The positions that have been espoused range from Eckstand's (1964) statement that the design of instruction is primarily an art, to the hypothesis that course design can be reduced to a series of well defined procedures which can be carried out by untrained personnel . Of the dozens of methods contained in the different manuals and in the related literature, none seem to have attained widespread acceptance. Campbell (1971) points out that a major problem with the avail able manuals is finat they do not indicate how their particular r‘Tnethodology differs from other methodologies or fronn traditional ways Of developing educational programs . At the present, the use of self- ‘ 1 A number of manuals state in the preface that no prior training is required, e.g. Modular Instruction by James Russell states: "The only prerequisite is a desire to improve student learning." (preface). 13 instructional programs is growing faster than any ofiner method of improving instruction (Novak, 1973; Cross, 1976) and fine required ingredient in the title of fine program seems to be "systems approach" even when there is little agreement as to what that term means . This confusion is primarily the result of three factors: lack of standardized terminology, problems associated wifin educational innovations, and the evolutionary nature of fine systems approach to manual design. Each of these will be discussed in some detail in this section. 1 . Lack of Standardized Teminolggy Manuals seem to use similar terms: objectives, task analysis, methodology, media selection, sequencing, objective performance rnneasure, criteria referenced testing, individualized instruction and evaluation. The use of a common terminology creates fine initial impression of high content similarity among the manuals. However, closer inspection of the operational definitions given to finese terms shows finis impression to be false as the following example will illustrate. Virtually all of fine manuals use the term "task analysis" but fine operational definitions of task analysis provided by the 14 manuals differ both in content and in degree of detail. While some manuals leave much to the discretion of the analysts, others are so specific as to provide a form broken down into hierarchical categories such as role, duty and activity, or job, task, and element; others provide litfie or no structure as to the number or the types of categories to be used. Some require each task to be classified as psychornotor, cognitive or affective; others rate each task on each of these categories; still others ignore this breakdown. Manuals generally provide only one procedure for task analysis. When alternative procedures are not provided, the assumption is made that fine method given is universally applicable. This assumption is not warranted by the literature on task analysis. The Gilbreths (reported in Swain, 1962) in their pioneering work on improving industrial efficiency, developed the first formalized task analytic methodology. Their procedures were useful in time and motion studies on production line tasks. However, in the 1950's, R.B. Miller found finat the Gilbreth's procedures did not allow for the identification of human attributes used in com pl ex tasks (Swain, 1962). Miller developed a methodology entitled "task-demands analysis" because he believed that existing mefinods did not provide adequate 15 data concerning the demands which tasks make on the operator. Since 1960, fine number of available task analytic methodologies has risen dramatically. A number of theorists, after reviewing this state of affairs, have concluded finat no single method of task analysis can be generated which is val id in all circumstances (Gustafson, Honsberger, and Michelson, 1960; Folley, 1964; DeGreen, 1970; Rankin, 1974). The degree to which task analysis can or should be procedural- ized is controversial. The trade-off is that although higher degrees of proceduralization result in narrower ranges of application, they may permit the use of less qualified, less costly analysts. DeGreen's (1970) analysis of this problem led him to conclude that: (a) reduction of task analysis to a routine checklist procedure results in "a deluge of useless data"; (b) task analysis must always be viewed as a means and not as an end; and (c) the usefulness of task analytic data is a function of the degree of expertise of the analyst. Although the example used here is "task analysis", a similar presentation could be made concerning each of the terms shared by the majority of manuals: behavioral objectives, media selection, methodology selection, criterion referenced testing, objective performance measurement, sequencing, evaluation. Research and analysis are needed to determine for each of finese concepts, the 16 degree to which procedurealization can be achieved, the generality of those procedures, and the skills necessary to apply them . 2 . Problems of Educational Innovations The degree of acceptance of a given innovation is shaped by factors other than its inherent advantages and limitations. Campbell (1971) stated that educational innovations have historically followed a predictable life cycle, and constructed a three-stage model of that process. In the first stage , a new technique appears and develops a large following of advocates who cl aim to have successfully applied the technique. The second stage consists of numerous modifications of the basic technique. The third and final stage in the life cycle of educational innovations is fine appearance of criticism by a few vocal opponents, which grows into an inevitable backlash. According to the model, this criticism does not serve to stimulate improvement of the technique, but to stimulate fine devel op- ment of a new technique. At that time the cycle starts anew. While Campbell's model is primarily descriptive, Milsum (1968) presents a phenomenon called the "bandwagon effect" which hel ps explain the model. The bandwagon effect serves to transform researchable hypotheses (educational innovations) into political entities, thereby t riggering the mechanism which leads to the innovation's 17' downfall. The mechanism works as follows. As the number of researchers, developers, theorists, administrators, laboratories, schools, etc. , who have vested interest in the innovation grows, the resistance to critical examination of the innovation and to the consideration of alternatives also grows. In addition, claims are made for and have become entrapped in the political arena. The process by which the innovation attains the reputation of a panacea has an unwanted side effect. The greater the number of people who attempt to use innovations based on unfulfillable promises, the greater the number of people will be who are disappointed by it. As this number grows, the criticism and backlash predicted by Campbell's model occur and eventually result in the downfall of the innovation. According to Campbell (1971), SAT is the current innovation, and is following the life cycle predicted by his model. That SAT has been touted as a panacea and has fallen victim to the bandwagon effect was first documented in 1968 by Hartley. He concluded that the SAT literature is "long on persuasion and short on critical self appraisal ". He believed this to be the result of over- 2eal ousness in attempts to use the new mefinodol ogy wifinout a clear Understanding of what it was supposed to produce. Carter's 1969 article, "The Systems Approach to Education: Mystique and Reality" provides not only a review of the problems created by the bandwagon Effect but also a realistic assessment of what can be expected from SAT. 18 Sugarman, Johnson and Hinton (1975) provide further support data and analysis in finese two areas. 3. Systems Approach The systems approach to training, SAT, evolved from "systems analysis" (alternatively called "the systems approach"), a methodology developed during World War II, to solve problems created by rapidly advancing weapons systems technology. After the war, the mefinodol ogy was found useful in the solution of problems in a variety of fields (Saettl er, 1968). In the late 1950's, fine first attempts to apply systems analysis to the design of training programs were undertaken by the Rand Corporation (Kershaw and McKean, 1958), and by the Human Resources Research Organization (Hoehn, 1960). The goal of early SAT developers was to generate tools which could aid training programs design personnel in their day-to—day work. These tools consisted of models, finat is, formalized sinnpl ifications of methods and techniques which other experts had found useful. These models were intended to be used, modified or ignored, in any particular situation, based on fine discretion of the user. They were not intended to relieve him of his responsibility as a decision maker. 19 The early 1960's witnessed fine emergence of a new technology which greatly affected the evolution of SAT. This new technology was based on the hypofinesis that if training program design experts could formalize models of fine mefinods and techniques finat made them successful, then laymen could follow these models and produce the same result at lower cost. The main thrust of developmental efforts under this technology has been the production of manuals which attempt to reduce fine design of training programs to a linear sequence of procedures which can be carried out by personnel inexperienced in training program design (Dicket son, Shuiz and Wright, 1970). During the middle and late 1960's, the procedural ized SAT concept generated a great deal of literature. The original, generic concept of SAT, which remained relatively dormant during finat period, has been the subject of renewed interest during fine 1970's. This is, at least partially, a result of a re-evaluation of fine state-of-the-art of educational psychology (Campbell, 1971 ; Glaser and Resnick, 1972; McKeatchie, 1974), which has concluded that fine avail able theory and empirical evidence on the process of learning and teaching do not support the procedural ization of fine training program deveIOpment process. As McKeatchie (1974) pOints out, psychologists are much less sure of the "l aws of learning" than finey were a few years ago. 20 Recent research is attempting to develop methods, models, and techniques which training experts can use, modify or ignore. This reflects a belief that deveIOpm ent of training is a complex problem, not solvable by procedural ized . methods. For example, in the selection of training media, Braby et al (1975), and Boucher, Gottlieb and Morganl ander (1973) have produced media selection models which specifically state that their goal is to assist rather finan to replace the experienced specialist. To conclude finis section here are two statements, made twenty years apart, which illustrate our present problem: "There is a simple job to be done. The task can . be stated in concrete terms . The necessary techniques are known. Nothing stands in the way but cUltural inertia." B.F. Skinner.(1954) "There is a complex job to be done. The task cannot be stated in concrete terms. The necessary techniques are not fiJlly known, The equipment cannot always be easily provided. Other things - primarily our ignorance of the complexities of human learning -— stand in the way, as well as cultural inertia. " J. Hartley (1974) 21 A. Justification for Information Chosen for Inclusion in the Manual In light of the previously discussed problems in current manuals on self instructional program design, a major task would be the selection and justification of information to be included in the Manual used in the present study. It was necessary to review the literature for educational practices and theories. This provided information which would enable the objectives of the Marual to be reached. The author was not aware of any literature wlnich sets out the process of selecting content for self instructional manuals. Shore (1973) states that there is no literature on this process and suggests that the way to decide on content is to look at existing manuals to determine their common elements found in module development. The common elements are: state objectives, order objectives (sequence), devise pre and post tests, design instructional activities, make avail able suitable resource materials. Klingstedt (1971) has recommended a series of steps very closely resembling those of Kurtz (1971). Summarized, finese steps are: Step 1. Learning outcomes are determined. Step 2. The learning outcomes are analyzed into smaller objectives and sequenced. Step 3. Tests are constructed which measure entry skills and objectives. 22 Step 4. Instructional activities are designed to help the learner master the objectives. Step 5. A post test measures the student's achievm ent of fine objectives . This author has chosen content of the Manual on fine basis of what is required to follow his seven step model and conceptual know- ledge required to understand that model . DevelOpment of the model is presented in Chapter III p . 49. The major concepts are: A. learning outcomes B. mastery learning C. learning processes D. analysis of learning outcomes E. sequencing of content F. criterion referenced testing and measurement G. formative evaluation, media selection and ind ividualizing instruction H. modular instruction The literature providing the research basis for these concepts is presented next, followed by a statement of philosophical basis and format of the Manual. In determining content the following were also kept in mind: criticisms outlined in the review of literature, part one; information obtained in interacting with DURC (presented in Statement of Need); and views currently being expressed in journals. A. Learning Outcomes The starting step of this author's model is the specification of learning outcomes. The use of the term "learning outcome" is a departure from fine usual term — objective, or behavioral objective. 23. First a review of the behavioral objective movement is presented and finen the reasons for fine preference of fine term "learning outcomes" . The need for objectives is documented by Tyler (1934) who advocated fineir use as both a goal for teaching and a measure of its effectiveness. The behavioral objective movement came into its own as part of the systems and accountability movements in education which required measurable (therefore observable) objectives. Mager (1965) responded to finis need wifin his three part formula for writing Objectives . As his first book was on objectives for programmed learning and as programmed learning was mainly due to Skinner, people have equated Mager's objectives with behavior- alism . Mager himself has never termed his objectives as "behavioral"; his concern was to provide measurable objectives (a form of account- ability). Since Mager's 1965 text there have been many others who have proposed a formula for writing objectives . Gagne (1974) proposes five parts to an objective: situation, learned capability, object, action and tools . Miller (1962) proposes a skills analysis and in his view obj ectives should include: 1 . an indicator on which the activity-rel evant indication appears; 2. the indicator or cue which calls for a response; 3. the control object to be activiated; 4. the activation or manipulation to be made; 5. fine indication of response adequacy or feedback . 24 The level of detail used in writing such descriptions is about the same as would be used for writing a set of technical instructions useful to a novice. Recently there has been a growing reaction against fine use of behavioral type of objectives (Ainsworth, 1977). Various reasons are given. Ashby (1965) points out that a learner's performance changes, according to the testing environment. Dressel (1977) describes covert learning which would not be measurable (or acceptable) if we insist that objectives call for observable behavior. In their later writings, Gagne (1974) and Bloom (1978) have moved from strictly behavioral objectives to a much wider concept of "learning outcomes " which allow for certain learning to be covert and testing to be spread over a period of time. MacDonald-Ross (1973) lists 16 objections to behavioral objectives. Geiss (1977) believes finat there is a pl ace for behavioral Objectives in training but not in education. Gronlund (1974) supports the concept of learning outcome and emphasizes that understanding is fine objective of learning, rather than behavioral outcomes which are the responses made after understanding occurs. A number of authors (Harrow, 1972; Armstrong, 1971; McAshen , 1 977) believe in"l earning outcom es" replacing 'obj ectives '1 25 They see thatfine learning outcome has two components 4 a goal and an evaluation component. The evaluation component may accept covert learning and different responses according to the environment. McAshen (1977) expresses what may be the concern of many: Once an educator understands finat the learning outcomes or con petencies are not fine same thing as the behavioral objectives (which rely on one-time observations of responses) he must question the value of any objective that is stated in behavioral terms only. The Manual proposes an approach which is a synthesis of a number of researchers (Sirnons, 1973; Armstrong, 1971; Smifin, 1972; Harrow, 1972) who advocate a more flexible "learning outcome" approach to the behavioral objective formula advocated by Mager. Learning outcomes are defined as goals, competencies or specific learning intents (McAshen, 1977). In the learning outcomes approach the objective has two components - a goal and an evaluation component. In evaluating the learner the focus will be on the achievement of the goal to be conducted finrough a sample of a number of behaviors over a period of time and accepting fine existence of covert learning (Dressel , 1977). Designers who prefer to present objectives in the format proposed by Mager or Gagne will not be discouraged from doing so but others who prefer a less rigorous learning outcome approach may do so. 26 2. Mastery Learning The concept of mastery learning is central in the move to individualize instruction. With resistance building up against CBE it is being suggested in literature that "mastery based education" replace CBE as the major focus for improving education finrough design (Block, 1978). In the Manual, mastery learning is the central philosophy. The concepts of mastery learning are fully treated in the Manual finrough two modules . DURC faculty reaction has been very receptive. The basic prenise that most students can learn what needs to be learnt, if fine process is approached sensitively and systematically, is a very Old one. The Jesuit schools emphasized this before the 17th century, Pestalozzi in the 18th century, and it has been part of the English universities' tutor system since its inception (Klaus, 1971). John Carroll's Model of School Learning (1963) and currently called Mastery Learning, is the modern approach to the notion that most students can attain a high level of learning capability. The aufinor's interpretation of Carroll's Model is that if students are normally distributed with respect to aptitude for some subject and all students are given exactly the same instruction, then achieven ents measured at the completion of the subject will be normally distributed. Under 27 such conditions fine relationship between aptitude measured at the beginning of the instruction and achievement measured at the end of the instruction will be relatively high (typically about + .70). Conversely, if students are normally distributed wifin respect to aptitude, but fine kind and quality of instruction and learning time allowed are made apprOpriate to the characteristics and needs of each learner, the majority of students will achieve mastery of the subject. And, fine correlation between aptitude measured at fine beginning of instruction and achievement measured at the end of instruction should approach zero. Carroll's (1963, 1970) model states that the level of mastery reached by a learner on any instructional task is a function ‘of the time actually spent learning the material and the amount of time he needs to master the material. The amount of time a student actually spends learning thematerial depends on two factors: time allowed, and his perseverance. The amount of time needed by fine stude nt is dependent on finree factors: aptitude, quality of the instructional materials, and his ability to understand the instructional materials . 28 Research findings on mastery learning have been impressive (Keller, 1968; Block, 1971; Bloom, 1971). However, as Cross (1976, p.77) observes Those two stalwarts of the school system - grades and semesters - become almost meaningless when mastery learning is implemented. Ideally, all students would earn A grades, and they would take as much time as necessary to accomplish this level of mastery. The Manual has two modules on mastery learning, which take a total of over four hours to complete. The emphasis is on concepts and supporting research findings to give the designer a strong knowledge base for possible attitude change (from traditional norm- referenced approach to a mastery approach). The problem of grades and semesters raised by Cross are not discussed as finese are mainly organizational problems vvlnere the individual faculty member has very little control. It is a speculation on the part of fine author that given the two modules on mastery learning, fine designer will gradually incorporate as many mastery concepts as organizational constraints will allow. 29 3 . Learning Processes The Manual places great stress on the learning process; it continually asks the reader to start the design process by asking "how can fine learner learn finis objective?" rather than the common approach which starts wifin "how should I teach this?" . Since Pavlov and Thorndike began their studies of learning, thousands of experiments have been conducted on the learning process. The Manual does not follow any particular school of learning or researcher, but is a synfinesis of fine generally accepted theories . Consequently fine theories of Thorndike (1921 ), Skinner (1968), Ausubel (1968), Bruner (1966, 1971) and Gagne (1974) are prominent. Bruner (1966, 1971) is concerned wifin indUcing active participation in the learning process on the part of the student, catalyzed by a "discovery-l earning" environment, and by frequent challenges to solve novel problems. To Bruner there are three major stages of intellectual development; these are fine enactive, the iconic and the symbolic representations. He has based some of his work on Piaget and in turn, much of Gagne's hierarchies are based on these three basic representations . Ausubel (1968) is primarily concerned with meaningful reception learning and the acquisition and retention of knowledge. The major emphasis of his fineory is on the inferred processes presumed to be in operation. The major concepts taken from Ausubel and used in the Manual are: advance organizer, anchoring ideas, cognitive structures, subsumption and assimilation . Skinner (1968) and Thorndike (1921) are very similar and are treated togefiner. Skinner, as is typical of the S-R tradition, limits his attention and discussion to observables. He is concerned almost exclusively wifin input-output relationships and does not write about inferred variables . The concepts used in fine Manual which are directly derived from these two researchers are: stimulus, reinforcement and contingencies of reinforcement, chaining, shaping, respondents and operants. Gagne (1974) emphasizes the learning of several kinds of learning outcomes, each requiring a different kind of mental process. The conditions for learning involve the interaction of internal conditions of fine learner, and the external conditions of the learning environment. Each kind of learning outcome requires a different set of these internal and external conditions. 31 There is one additional theory of learning which is used in the Manual and ignored in ofiner manuals reviewed. That is fine information processing theory. According to this theory, the processes that one must conceive in order to explain the phenomena of learning are those finat make transformation of inputs to outputs in a fashion somewhat anal agous to the workings of a computer. These various forms of transformations are what goes on "inside the learner's head" - fine learning process. Theoretical accounts of the information processing theory are: Atkinson and Shiffrin (1968), Norman (1970), Anderson and Bower (1972), Lindsay and Norman (1972). The information processing theory is closely related to cybernetic concepts in biological-behavioral sciences. Von Bertalanffy(1966) explains the cybernetic system in this way: "The minimum elements of a cybernetic system are a 'receptor' accepting stimuli (or information) from outside as an input; from this information a message is led to a 'center' which in some way reacts to the message and, as a rule, amplifies the signals received; fine center, in its turn, transmits fine message to an 'effector' which eventually reacts to the stimulus with a response as output. The output, however, is monitored back, by a 'feedback' loop, to the receptor which so senses the preliminary response and steers fine subsequent action of the system so that eventually the desired result is obtained. " (p.40) 32 The different learning theories mentioned so far are used thoughout the Manual particularly in Step 4 (planning of the lesson) and Step 5 (construction of the lesson), when finey are most applicable. The aufinor sees no problem in this approach as fine theories used are not contradictory but rather complementary. Full statements of learning theory would be beyond the SCOpe of fine Manual. Brief abstracts accompany fine major bibliography for finose who wish to pursue any particular fineorists . There is one exception - that of information processing theory. A module on information processing fineory is included in the Manual in response to interest in this fineory expressed by faculty during formative evaluation . 4. Analysis of LearningQutcomes Usually SAT refers to this step as "task analysis" and part one of the review of literature points out that all fine manuals reviewed presented only their own methodology without reference to other alternatives, thereby giving the beginning designer a naive view of straightforwardness and simplicity of the process. In the present Manual finree alternate methods are recommended, according to the learning involved. The designer is to choose the method which suits the type of learning outcome which is desired. If the learning outcome involves procedural tasks then the approach of Davis, Alexander and Yelon (1974) is recommended. When the learning outcome involves mostly cognitive processes finen the approach of Gagne (1974) is recommended and when the learning outcome involves both procedural and cognitive processes then fine approach of Singer and Dick (1974) is recommended. Through interviews with target faculty and during formative evaluation, the author found that the actual choice of topic as a suitable "chunk" proved difficult. The work of Cook and Walbesser (1973) addresses this concern and fineir methodology is included. Briefly, they suggest fine use of a topical hierarchy before developing an instructional hierarchy. 34 The Manual is mostly concerned with the teaching of higher cognitive skills and therefore fine work of Gagne and Briggs (1974) is used more extensively. Much of their methodology calls for hierarchical analyses and sequencing; research findings in finis area follow. 5. Sequencitg of Content Duncan (1972) indicates that there have been three main approaches to research on sequencing. Some investigators have ' taken a fineoretical approach - basing their work eifiner on Skinner's ideas about shaping behavior or on Gilbert's ideas about the chaining of sequences of responses (Gilbert, 1962; Mechner, 1967). Ofiner investigators have looked in more detail at Mager's approach of determining fine sequence preferred by fine learner rather than that preferred by the teacher (Mager, 1961; Mager and Clark, 1963). Ofiner investigators have based their approach to sequencing by manipulating fine internal structure of the subject matter with which they were dealing, an approach owi ng much to the fineoretical position of Gagne (Gagne, 1970; Gagne and Briggs, 1974). The Manual suggests finat where the content has mostly cognitive skills then the methods advocated by Gagne be followed. However, as research does not identify a "best" method the Manual also mentions alternate methods (but in less detail). 35 Each of these approaches will now be briefly considered . AS a part of his approach to programming, Gilbert advocated that a sequence which could be classified as chain-like ( a followed by b then c then d etc.) should be taught retrogressively. That is, the learner should make the last response first. Gilbert advocated that doing the last response--completing fine chain—was the easiest response to make and the most motivating to reinforce. He finerefore advocated that learners should, in effect, be programmed to make their responses to a chain in the correct order but always building up to completing the end of fine chain. Experiments have failed to indicate any superiority for finis approach (Wilcox, 1974). A number of studies have offered support for Mager's learner-controlled rafiner than instructor-controlled sequencing (Horn, 1964; Briggs, 1968; Issing and Eckert, 1973; Newkirk, 1973) although there have been exceptions (Allan and McDonald, 1966). In many of these studies, though, the results are confounded wifin other variables which could have affected the results (Merrill, 1973). The most interesting approach to sequencing, however, has concerned itself wifin fine implications of the argument finat if a subject matter has an internal structure, then finere should be a logical teaching sequence consequent upon it. Gagne argues that many subject matters have a hierarchical structure. What one has 36 to do to discover this structure, is to ask, "What does a learner have to know in order to do finis task when given only the instructions to do it?" An answer to finis question provides material to which one can apply the same question, and so on, defining in a sense a subset of skills, or more technically, a cumulative hierarchy of sub-tasks . The phrase "cumulative hierarchy" simply implies that the learner must be able to succeed at one level before he can go to a higher one. The results from recent experiments have not always supported Gagne's approach (White, 1973), but the hierarchical notion still continues to attract attention (Airasian and Bart, 1974; Kozma, 1974; Phillips, 1974; White, 1974). 6. Criterion-Referenced Testingand Measurement In a questionnaire administered to DURC, a series of questions concerned the members' practices in grading. The results showed that only one member utilized the philosophy of criterion- referenced testing. A check of term grades posted outside offices also demonstrated finat students' grades were closely along a normal curve. Consequently, criterion-referenced testing is prominent in the Manual, however, norm-referenced testing is also recommended for certain purposes . 37 Criterion-referenced tests are specifically designed to meet the measurement needs of irGtructional programs following a systematic design. In contrast, the better known norm-referenced tests are designed principally to produce test scores for ranking individuals on the ability measured by the test. A very flexible definition of a criterion-referenced test has been proposed by Glaser and Nitko (1971): ". . . [a test] that is deliberately constructed so as to yield measurements finat are directly interpretable in terms of specified performance standards. " (p.653). According to Glaser and Nitko (1971): The performance standards are usually specified by defining some domain of tasks finat the student should perform . Representative samples of tasks from this domain are organized into a test. Measurements are taken and are used to make a statement about the performance of each individual relative to finat domain. (p.653) Furfiner distinctions between norm-referenced tests and criterion- referenced tests have been presented by Ebel (1971), Glaser (1963), Popharn and Husek (1969), Glaser and Nitko (1971), Hieronymous (1972), and Livingston (1972). Hambl eton and Norvik (1973) have noted that the primary problem in criterion-referenced measurement is that of classifying a student into one of several mutually exclusive mastery states or categories. Mastery states are introduced to represent different 38 levels of performance on the domain of items measuring each objective covered in the criterion-referenced test. Typically, a cut-off score or mastery level score is set to permit the teacher to assign students, on the basis of fineir performance on each subset of items measuring an objective covered in the criterion- referenced test into one of two mutually exclusive categories - masters and non-masters. (See Millman, 1973, and Block, 1972, for disoussions of guidelines for setting cutting scores .) In fine Hambl eton-Novick formulation, criterion—referenced test reliability takes the form of an index indicating the consistency of decision-making across parallel forms of the criterion-referenced test or across repeated measurements (Swaminafinan, Hambleton and Algina, 1974). Validity takes the same form except, of course, that a new test or some other appropriate measure serves as the criterion. The Manual advocates the use of criterion referenced tests when evaluating student progress but asks the designer to consider norm referenced tests for post tests . This method is advocated by Yel on (1976) who points out finat employers need to know how students stand in relation to each other. 7 . Formative Evaluation A major feature of this author's model is the heavy emphasis on formative evaluation. The Manual recommends finat formative evaluation be conducted while the module is being developed . Such evaluation provides information to developers that would allow finem to modify and improve their product. 39 The inadequacy of current use of formative evaluation procedures in the development of products has been well documented by Komoski (1971). He notes that less finan one percent of all the 14,000 textbook titles being sold have been formally evaluated . Of the 80 manuals on fine design of courses which this author has reviewed, only two show evidence of formative evaluation. The heavy emphasis on formative evaluation in this author's program is based on the belief that in order to assess fine effective- ness of instructional systems, a variety of data types need to be utilized in fine program . Formative evaluation is conducted through the following: embedded or in-program tests, pre and post tests, and attitudinal surveys. Each of these will be treated in turn. 1 . Ennbedded tests have been found to be "very useful " (Baker and Al kin, 1973).. Their major usefulness is to test whether the student is mastering fine sub-objectives (Dick, 1968), to give constant feedback to the learner (Crowder, 1960) and as a diagnostic function, indicating what particular discriminations need additional attention. Glaser (1966) suggested that wifinin-program errors represented an inadequacy of the program itself. Recommendations, based on research, on the sorts of data to collect in program develop- ment have been forwarded by Markle, 1967; Baker, 1973; Dick, 1978. 40 A number of researchers have offered formative evaluation models: Scriven (1972) and Stake (1972) imply that it is best that the formative evaluation be performed by someone external to fine program . Scriven calls his approach "goal free evaluation" and establishes a rule in which the formative evaluator collects his or her own data' and renders assessment on the actual effects of the program . Stufflebeam(1971) and Al kin (1969) emphasize the necessity of structuring evaluation so that it serves decision making purposes by producing appropriate and timely information. There are numerous models and checklists for product development processes . These vary from conceptual schemes (Schutz, 1970) to comprehensive step by step procedural checklists (Borg and Hood, 1968). All models strongly advocate the use of formative evaluation as stated by Baker and Al kin, 1973: " . . . at the core of each model, regardless of its esotericism or practicality, is the realization and recognition that product development and formative evaluation are intertwined as snake and staff and that product revision depends upon the generation of formative evaluation data." The Manual synfinesizes most of the concepts and procedures discussed here; these form Step 6 of the Manual which is enclosed as Append ix D . 41 2 . Post test data. The form and frequency of gafinering post test data is not clear. Husek and Sirotrik (1968) and Shoemaker (1972) have described a procedure to reduce the amount of testing time requisite for program revision. Samples of test items are administered to samples of learners and the sum across all items is used as an index of program success. The number and use of subjects is an important point. Robeck (1965) used a single student as the data source and showed that this economical method Significantly improved fine product. The above procedure has been verified by Fleming, 1973, and Markle, 1967. The main problem was to determine which student to select. A variation of the single student procedure is advanced by Abedor (1972) who used a small group com bined with a debriefing. Baker (1973) commenting on Abedor's study points to an interesting byproduct of fine study: the analysis of fine data suggests finat obtaining feedback through procedures utilizing a student debriefing session may serve as instructional product development training. A number of studies have shown that when data from formative evaluation is used to revise the product then considerable improve- ment is achieved (VanderMeer, 1964; Gilbert, 1962). However, no research has been conducted into fine form that formative evaluation should take and how early in product development should evaluation take pl ace . 42 8. Modular Instruction This general heading includes fine concept of individualized instruction through fine use of modules . The effectiveness of individualized instruction through fine use of modules has been demonstrated in a large number of studies (Celinski, 1968; Ferster, 1968; Keller, 1968; Lloyd, 1969; Myers, 1970; Bern, 1971; Johnson, 1971; Kulik, 1974). There is ample evidence in literature that modular instruct- ion, be it a small part of curriculum or fine whole curriculum, is working. Brown et al (1976) describe the function of College IV, one Of five Grand Valley State Colleges in Allendale, Michigan. At this college, all courses are taught by a self-paced modular system of instruction. The school has attracted large numbers of non-traditional and adult students who cannot attend pre-arranged classes. The College has developed a flexible administration to allow for continuous registration and enrollment. Bridge (1976) surveyed 43 modular, self-paced courses in physical , social and applied sciences being taught in England and Ireland. The results show an overwhelming approval of self-paced modular approach both by students and faculty. Taveggia (1976) presents an overview of 14 studies which com pared learning outcomes of self-paced modular instruction and 43 conventionally taught courses. Student performance on course content examinations showed finat modular instruction is superior to conventional mefinods. The above are just three studies. Journals such as Higher Education, Educational Technology, carry a large number of similar studies. A recent issue of fine Journal of Personalized Instruction (3,1 of Marcln, 1977) carried a list of 54 major articles which give research findings supportive of modular instruction. The basic theme of fine Manual is that much of university instruction should be presented finrough fine use of well-designed modules where the subject matter and situational constraints allow finis (as outlined in Step 1 of fine Manual). 9. Diffusion of Educational Innovations The factors which encourage or impede the diffusion and acceptance of innovations in education have been discussed widely in literature (Lippitt, Watson, and Westley, 1958; Marcum, 1968; Bennis, Benne, and Chin, 1969; Havelock, Huber, and Zimmerman, 1969; Rogers and Shoemaker, 1971). The kinds of factors that students of planned change have identified as generally supporting innovation in education include, after fine outline of Glasser (1971): organizational attitudes that support change; clarity of goal structures; 44 organizational structures finat favor innovation; professional ism of staff; organizational autonomy; and strong vested interests in preserving status quo methods of operation. Of particular concern to this study is fine use of a product to encourage the diffusion and acceptance of an innovation. Under the Statement of Need (p.6) it was stated that the Manual would also serve as a change inducing mechanism . The author saw the Manual as one of the means of diffusing an educational innovation (which in this study is CBE) by having designers produce modules (visible products). The author sees the availability and trialability of products to be a necessary part of an acceptance process, because the innovation (CBE) amounts to a conceptual approach to education, made up of many concepts. The Manual transposes these concepts into concrete visible products which can be demonstrated, tried and tested. The theoretical position for the author's assumption for fine need for concrete products is supported in literature. First, the diffiusion of an innovation is a process. This process is described by Katz, Levin, and Hamilton (1972) as starting wifin acceptance, over time, of an idea by individuals in the systenn . Rogers and Shoemaker (1972) also see diffusion of innovation as a process over a series of stages. They see the process as starting wifin awareness of fine innovation, then a Show of interest in fine innovation, followed by opportunities to evaluate the characteristics of the innovation, 45 then fine innovation must be trial able before it is finally adopted. Rogers and Shoemaker (1972) found that the acceptance of an innovation depended on five characteristics or attributes of that innovation as perceived by the target population: (1) fine relative advantage of the innovation over other methods or products, (2) the compatabil ity of fine innovation with ideas already held, (3) the relative complexity of the innovation (a less complex innovation has a better chance of acceptance over a more comm ex innovation), (4) that the innovation be trialable and (5) the innovation be observable. AS stated earlier, the conceptual nature of the innovation (CBE) required that it should be presented in a trial able and observable format. Rogers (1972) provides further guidelines as to fine attributes of an innovation which determine its acceptance; finis is further discussed on p . CHAPTER III M ETHO DO LOGY A. Type of Research This dissertation is a pilot study. According to Borg and Gall (1971‘) a pilot study is used to experiment with a variety of approaches, ideas, procedures finus allowing an appraisal of their adequacy, and also allowing unforseen problems to surface (pp. 60-61). The dissertation follows what Borg and Gall (1971) term as "research and development" (R & D) methodology. This type of research differs from most basic and applied research projects 1 that can in a number of ways. Its objective is a finished product be used effectively by a designated population. The most critical difference between basic and applied research and educational R & D is fine sequence that is followed. The typical steps in the R & D sequence are (after Borg and Gall, 1971, p.31 ): 1 . Develop a set of objectives that fine product should achieve. 2. Conduct research or review previous research to discover the deficiencies of current products and to identify approaches The "product" in finis study is the Manual 46 47 finat are likely to overcome these deficiences. 3. Develop a product to the point where one may reasonably expect that it will accomplish its objectives . 4. Test finis product and evaluate its effectiveness in meeting objectives. 5. Revise the product on fine basis of the field test results. 6. If it is successful, put fine product into Operational use. The R 8: D sequence proposed by Borg and Gall (1971), was followed in this way: 1 . Develop a set of objectives that the product should achieve. A set of cognitive objectives, followed by production objectives, is presented on p. 58. The designer will acquire fine cognitive skills and finen transfer the cognitive skills to fine actual production of a module . 2. Conduct research or review previous research to discover the deficiencies of current products and to identity approaches finat are likely to overcome these deficiencies . Much of finis is done in fine Review of Literature (pp. 11-45). and in the Statement of Problem (pp. 1-6) 3. Develop a product to the point where one may reasonably expect that it will accomplish its objectives . Research underlying fine major components of the product (the Manual) are presented in the Review of Literature. The mefinod 48 of develOping the Manual is described on p. 49. Development also included rigorous formative evaluation. 4. Test finis product and evaluate its effectiveness in meeting ogjectives. Testing takes finree forms: a. Formative evaluation of the Manual; b. Evaluation of the products of the Manual (the module) which is done finrough evaluation by a panel of expert judges using criteria set out in Appendix A; c. A field test of fine modules as explained in Summative Evaluation . The final revision of the product, so that it can be put into operational use, is not part of this study. 49 B. Development of fine Self Instructional Manual The process of developing the Manual was through four main steps: a) determining fine philOSOphical basis and format, b) identifying content, c) identifying cognitive objectives, d) identifying product objectives, and e) formative evaluation. The Manual is enclosed as Appendix D . 1. Philosophical Basis and Format of the Manual PhiIOSOphically, fine Manual is to provide information in possible techniques; the term "techniques" being used in its broad sense as defined by Ellul (1967): technique is nothing more than means and fine ensemble of means (p. 19). The Manual follows a philosophy which calls for the integration of a systems approach to instruction with that of a humanistic approach to education. Fox and DeVault (1974) found finat the best examples of individualized instruction are those that blend these two approaches. This approach is fully explained in fine Manual . In fine vernacular of fine target population, the Manual offers an educational cafeteria of techniques instead of the more common educationa "plat du jour". The aufinor does not suggest a radically different view or urge the substitution of a new system for an existing one. Instead, the Manual presents a varied array of choices to 50 achieve fine same objective so as to accommodate fine increasing heterogeneity of those involved in education, an approach favored by Fantine (1976). In a number of instances the Manual carries suggested further readings for alternate approaches and views. Its methods and approaches are in direct response to the needs expressed by fine target pOpul ation . Competency based education, modular instruction, or individ- ualized instruction constitute an innovation to most faculty in fine target population. Therefore the findings of Rogers and Shoemaker (1971) are helpful on how to gain acceptance. Rogers and Shoemaker advocate a gradual introduction of new concepts which sould be perceived as compatible with existing methods and beliefs. Through gradual introduction, the innovation should also demonstrate its advantages, be trialable, and the process should be observable. Consequently, the Manual introduces new concepts slowly, giving concrete exam pl es from higher education, particularly dietetics, and presents alternatives to choose from . Generally the format of the Manual may resemble a programmed text, but cannot be equated with Skinnerian mefinods. The fineoretical base for Skinner's (1954) views are severely criticised by Annett (1969; 1973) and others . 51 The Manual itself is in a modular format; therefore it often acts as an exemplar. Various techniques of presentation are used, some for the purpose of illustrating alternatives, at other times because finey appear fine most effective way of teaching . The format of fine Manual is print wifin some graphs, flow- charts and models. The use of print is considered the most effective way to achieve fine learning outcomes as advocated by Brigg's (1978) method of selecting appropriate media. Chunks of information usually vary according to the difficulty of content but usually are large, in line with fine target pOpulation's capabilities as advocated by Holland (1965) and Leith (1966). As Markle (1969) points out, programs of today contain various step Sizes; the size of fine step is largely determined by what is corsidered appropriate for fine learner, and the nature of fine material. The Manual used mainly linear techniques, but some branching is used for accelerated progress and remedial work. Holland (1965) and Leith (1966) showed finat when comparing linear and branching programs for older, intellegent learners, there was no difference in test results, but branching programs were superior in terms of time taken to learn. Frequency of tests is varied in fine Manual . Research by 52 Holland (1965), Anderson (1967) and Annett (1969) Show that low ability learners benefit from immediate knowledge of results. For above average learners, testing can be varied. Attention needs to be paid to the nature of fine subject matter being learned (easy - difficult), the kind of response being made (overt - covert), its frequency, and fine kind of feedback deemed appropriate. A study by Grundin (1969) indicates how these features may interact. In Grundin's study, overtresponding produced better results than did covert responding, but fine older the learners, fine less the difference. However, in his study, the effect of overt responding interacted wifin the frequency of feedback. In finis experiment, with overt responding, frequent knowledge of results seemed superfluous, or even detrimental . While immediate knowledge of results does not always lead to increased learning, this does not mean finat the technique of providing immediate feedback is always erroneous. Indeed, providing knowledge of results is probably one of the most important principles of teaching (Annett, 1969). In the context of programmed learning, Annett (1973) says, " Reinforcement of each step? Well you can hardly argue with that. One does not have to be an ardent S-VR theorist to see that at some stage the student must be aware of what the right answer is . " 53 Annett's argument is with the reinforcement interpretation of this principle (Annett, 1969; 1973), not with the idea of frequently telling a student how well he is doing. Information about the adequacy of a response is more important than reinforcement. Consequently, in the Manual answers are often lengfiny, providing a "suggested" or "expected" answer. Research on overt versus covert responding produced similar mixed results. In many cases no Significant differences were found between the test results of learners who wrote their answers down or learners who merely "thought" them . Again, however, there were indications of where overt responding was superior - for example (i) when fine learners were young children; (ii) when the material was difficult; (iii) when the programs were fairly lengfiny; and (iv) when particular (novel or specific) terminology was being taught (Holland, 1965; Leith, 1966). A more careful analysis is required of what is meant by the phrase "active responding". AS Annett (1973) wrote, activity on the part of the learner seems a good idea, but what sort of activity? It is important to note that with intelligent learners covertly responding to programmed instruction there is still far more questioning of the learner than there is in a conventional teaching- learning situation. There is evidence in ofiner instructional contexts 54 to indicate how important this questioning might be (Glaser and Resnick, 1972; McKeachie, 1974; Prosser, 1974). There are times when the Manual suggests that for certain types of learning there be a departure from individual learning to pairs or even groups. Several experiments have been performed which have conn pared fine results obtained from learners working in pairs, in trios, in small or even in large groups (Hartley, 1968). In the majority of cases no significant differences in test results have been reported. However, for learning outcomes which deal with fine affective domain, group interaction has resulted in better clarification of values and more lasting learning. The Manual also suggests that at times fine instructor and modular learning be integrated. Hartley (1972) gives research evidence that the instructor and module working together provide a more efficient teaching technique than eifiner working in isolation. Individualized learning is usually self-paced, and that is also the mefinod advocated in fine Manual. However, finere are reminders throughout that a steady pace needs to be maintained, for as Landy et al (1969) points out, the rate of work expands to fit fine timetable. 55 2, Identification of the Manual's Content The need for the Manual . is based on the Statement of Problem (p. 1 ) and fine Statement of Need (p.5 ) earlier in this disse rtation . To meet the stated needs, the Manual must serve two functions. First, provide the cognitive skills necessary for the construction of modules. Second, provide fine step by step guidelines for designing and producing a module. For the first function of the Manual (that of providing the necessary conceptual information) fine content was identified partly through the use Of Gagne's (1975) hierarchical analysis, which (paraphrased) states: What simpler knowledge would a learner have to possess in order to learn skill x, the absence of which would make it impossible for him to learn skill x. That is to say, in conducting such an analysis, one seeks to identify essential prerequisites, those sub- ordinate skills which are actually incorporated into the skill to be learned.1 A full account of fine hierarchical analysis which followed 1 Research on Gagne's hierarchical analysis is in the Review of Literature. 56 is too lengthy for inclusion here, however the main required intellectual skills which were identified included the concepts associated with systems approach, mastery learning, criterion referenced evaluation, specification of learning outcomes and hierarchical analysis of cognitive skills. The format and amount of content presented was partly decided on fine evidence provided by questionnaires and quizzes which faculty completed during DURC Learning Sessions (mentioned in Statement of Problem) as well as by the questions asked by faculty when interviewed in the summer of 1976. The second function of fine Manual is to provide quidelines step by step, for fine design and production of a module. One very useful conceptual model was developed at Florida State University and presented on the next page (Figure 1). The Florida State Model has been in use for nearly ten years. The author's main criticism of this model is that its concurrent activities are confusing in a self instructional manual. Some of fine other models considered were fine IDI1 and Learning System Design (Davis, Alexander and Yelon, 1974). The IDI, with its nine major steps appeared too task oriented and lacked sufficient guides for product development. From the three models just mentioned, as well as a number of Instructional Developnn ent Institute of National Special Media Institute (1972). 57 lmntvmg IMNUCIIOMI Goal _ Canducnng instrucuonu Anal 1m: Fig. 1 -- Systems Approach Model for Designing Instruction from launching Entry acumen.

Formative Evaluation of Manual This evaluation was carried out along the guidelines suggested in Step 6 Of the Manual presented in Appendix D. Formative evaluation of the Manual was conducted in three phases. First a one to one phase; second, a small group phase; and third, one extended small group situation. The one to one testing was conducted with three subjects: a graduate student from Instructional Development and Technology Department, a graduate student from Food Science and Human Nutrition and an instructor from Food Science and Human Nutrition. The form of the testing was for the author and the "l earner" to go through all the components word by word. The learner would comment on anything which seemed unclear and the author noted the comment and recorded the possible alternatives. As a result of this phase, the Manual was extensively rewritten. The extended small group phase was conducted with DURC starting August 1977. Participants were asked to work through a segment of the materials and make comments and suggestions prior to coming to the weekly meeting . At the meeting participants expressed their reactions to the materials and took the post test. All the materials were collected, comments considered and tests eval uated . 63 After revisions based on this phase were concluded, it seemed that the Manual could be Put to its intended use. In addition, a Masters' candidate (Morrissey, 1978) in the Depart- ment of Food Science and Human Nutrition selected the Manual as fine tOpic for her Unesis . (3. Method of Pilot Testing: An Overview Pilot testing consisted of an evaluation of the modules and the reports which were produced by the designers as a result of working through the self instructional Manual . These reports provided documentation on the processes which went into developing the module and were thereby helpful in the evaluation of the module. Guidelines as to what should be included in the report are stated in the Manual . 1 . Sarmale Selection Instructors in higher education who expressed interest in new methodology to improve their teaching were approached at random to see if they were interested in developing a module. The instructor needed to be in a field other than education and not have had formal 54 training in instructional design. The interested instructor (designer) was given a copy of the Manual and encouraged to follow the directions. The designers were fully briefed as to fine whole process and what the process entailed in tenms of resources. It was agreed earlier that fine minimum number of instructors to be included in finis study should be at least five while fine actual number turned out to be seven. Designers were geographically dispersed with some in Australia and others in Hawaii; this prevented input or 'contamin- ation' by the author. 2. Data Collection Each module was evaluated by different pairs of instructional designers who were either faculty or advanced degree students in Instructional Development and Technology at Michigan State University. The evaluation consisted of assessing each module with respect to each of 26 questions developed by the aufinor. Each question was worth a stated number of points for a total of 100 and each question had a stated criterion level. Points were awarded by each evaluator as outlined in fine rationale which accompanied the evaluation instrument. (The evaluation instrument and rationale for awarding points are appended as Appendix A.) Development of the 26 question evaluation 65 instrument, rationale and objectives was started by the author as partial requirement for IDD 633 at Florida State University with Dr. L. Briggs, as instructor. At fine time, modifications had to be made to fine evaluation instrument and fine rationale to bring about agreement with the stated objectives. Since that time, changes have been made to the objectives and consequently to fine evaluation instrument. In April 1978, the author visited Florida State University and took the objectives and evaluation instruments to Dr. W. Dick, another author in the field. Dr. Dick suggested several changes and also gave a c0py of an evaluation instrun ent which he has developed, for possible further develOp- ment of fine aufinor's evaluation instrument. Inter-evaluator reliability was determined by comparing the judgements of fine two evaluators who independently reviewed each module and its accompanying report. Evaluators were guided by the rationale which accompanies the criterion referenced evaluation instrument. 3, Attitudinal Questionnaire Each designer was asked to complete an attitudinal questionnaire at fine completion of fine study. The purpose of finis questionnaire was to guage the designer's attitude to the whole process of learning through fine Manual, and the design and testing of fineir module. 66 Questions of particular interest are: would finey design another module; if finey designed anofiner module how long would it take in relation to their first attempt; would finey recommend this method to a colleague; has finis experience changed their attitude and methods to fineir everyday teaching? A copy of the questionnaire is in Appendix E. 4- Summative Evaluation Summative evaluation, e.g. experimental comparison of modules wifin conventional instruction, was not included in finis dissertation due to the extensive logistics involved. Designers were not able to carry out their summ ative evaluation and report their findings before the deadline set for finis dissertation. However, the summative evaluation of one module (Morrissey, 1978), which was produced as partial requirement for a Masters' degree, is reported in Chapter IV and Appendix C as a possible example or for replication studies. CHAPTER IV DESCRIPTION AND RESULTS OF PILOT TESTING OF THE MANUAL The purpose of this chapter is to report the results of the pilot testing of the Manual. The chapter is divided into two sections, 1) description and 2) report of findings. Description The purpose of finis pilot study was the evaluation of the Manual. As outlined in Chapter III, this was done through the evaluation of six products (modules), designed along the conceptual, information and step by step procedures provided in the Manual. Evaluation of each module was carried out by two competent instructional designers using a criterion referenced instrument (enclosed as Appendix A) and following a set rationale for the awarding of points (also in Appendix A). The designers were instructors in higher education, three in Australia and three in Hawaii; each designer produced one module. Choosing designers geographically distant from the aufinor controlled for author "contamination". 67 68 Designers in Australia were affiliated with the Caulfield Institute of Technology in Melbourne and fine designers from Hawaii included a former professor attending the University of Hawaii as a graduate student, an instructor at the University of Hawaii, and a former professor now working as a consultant, living in Honolulu. The designers in Australia were contacted when the aufinor visited Australia in December, 1977 and fine designers in Hawaii were contacted while the author worked at the University of Hawaii in January to March, 1978. A designer was accepted when in conversation it became cl ear that he/ she had very little, if any, training in fine theory or methods of education. This lack of education background needed to be later verified by fine responses to a pre entry test which the prospective designer was asked to complete. This pre entry test was essentially the same as used in DURC except that questions 10 and 11 were omitted, and questions 3 and 4 were changed to percentages for the prospective designers in Australia because grade points are not used there. Questions 3 and 4 were also marked as not applicable to fine prospective designers in Hawaii who was working as a consultant. The pre entry test is enclosed as Appendix B; it was still titled "Survey on CBE" as fine aufinor considered such tenms as "test" or "examination" to be inappropriate with the prospective designers . 69 Results of the pre entry test or "Survey on CBE" are also found in Appendix B. Suitable prospective designers were given a copy of the Manual (as in Appendix D) and asked to work through it. Designers were instructed to keep in touch to report fine progress made on the module. Completed modules and reports were expected to be wifin the author by June 30, 1978. The first module arrived in late May and the last module towards fine end of July. Designers were then sent a Post Module Development Survey which they were asked to complete and return to fine aufinor. This survey is enclosed as Appendix E. When a module arrived, the author sought out competent evaluators. The evaluation was carried out by three advanced degree students and four faculty, all associated with Instructional Development and Technology at Michigan State University. No evaluator was asked to evaluate more finan two modules and for each module that was evaluated by a graduate student fine ofiner evaluator was a faculty member. 7O Findi s Altogether there are six findings which can be supported by data. Findings 1 ,2, and 3 relate directly to the research questions posed in Chapter 1: 1 . Can a self instructional manual on designing modules be developed where finose who complete the manual reach mastery level on its contents? 2. Will attainment of mastery of fine self instructional manual result in a module which meets some minimum acceptable standards? 3. Will the module so developed obtain results at least as good as those obtained finrough traditional methods of instruction? Findings 4,5, and 6, while not directly related to the above research question, are, neverthless of interest. Finding 1: Mastery of Key CBE concepts was acquired through fine Manual. Data relevant to this finding is presented in Table1 . Key concepts, considered as essential for fine design of a module had earlier been identified (p. 21 ). Mastery of finese concepts was operationally defined as scoring above criterion on fine 26 item 71 evaluation instrument (in Appendix A) on which the modules and accompanying reports were evaluated. Perusal of Table 1 indicates that the designers achieved considerable mastery of key concepts as measured by the modules actually produced. Of fine 312 evaluations made, only nine were below the criterion level. However, each of the nine below the criterion level, judgennents were made by one evaluator but not the ofiner evaluator. From personal interviews with evaluators it seems that the "fail" judgements were either because of fine ambiguity of the rationale given in fine evaluation instrument or that the item did not seerm applicable for finat particular module or its intended users. For example, item VI A, preinstructional activities, was not fully addressed by two designers who maintained that they knew their learners to be highly motivated and therefore saw the need for only minimal amount of motivational preinstructional activity. In both of finese cases one evaluator rated fine item 0 but the other evaluator awarded at least the criterion level of points as a sign of accepting the designer's rationale. A close study of all of fine items which were judged as not reaching the criterion level revealed that the designer understood fine concepts involved 72 but considered their use in the module as inappropriate. As mentioned earlier, the designers chosen for finis pilot study had very little knowledge of key CBE concepts. From the data in Table 1 it is cl ear that the vast majority of key concepts haVe been mastered by all designers and thus it is suggested finat these key concepts can be and were acquired primarily finrough fine Manual. Finding 2: The Manual led to development of acceptable modules A total of six modules were designed. All six modules reached fine criterion level; findings are reported in Tables 1 and 2. It is reasonable to conclude that the Manual led to the development of acceptable modules as all designers had stat ed at the outset that they had no knowledge of how to design modules and their knowledge of key concepts was very low (see Appendix B). The question which remains unanswered concerns the amount of assistance fine designers required and received apart from the information provided in the Manual. Judging frorm the evaluation questions sent to the aufinor, four stated that finey required further reading of fine recommended texts, particularly Gagne (1975); three stated they required no further readings. No designer reported having sought any consultative help from anyone . 73 There was one deficinecy in the Manual expressed by the designers. They indicated the need for a finished product as a model of what was expected; this requirement was expressed by all designers. As the designers were the first group to produce modules there were no finished products avail able as models. While there were no finished products which met the criterion set down, there were some which in some ways resermbled the required product. The first such module was the one developed by the author, called 53921 which is on Control Data Corporation's flatg system . The designers in Hawaii had access to this program but the ones in Australia did not. To fill finis need for models, the designers were referred to Briggs (1977) where finree modules are included. However, those modules had been developed on a different format and therefore would have only been of minimal help to the designers (perhaps even confusing). However, the point was made that the designer experienced certain (unnecessary) anxiety which could have been avoided by the inclusion of a completed product. The absence of a finished product as a model for the designers in Australia seermed to have very little effect on the quality of their modules as the evaluations were equival- ent to the evaluations of the modules designed in Hawaii where the designers had fine Opportunity to see a module. 74 Docs.

When asked in the Post Module Development Survey (Appendix E) if finey would design another module following the Michigan State University model, all designers answered yes. A further question in fine same survey asked: would you recommend finis model to anyone else? The answer again was yes from all designers. Wifin these positive findings and an absence of negative findings, it may be concluded that the Manual develops positive attitudes to CBE and module design . Finding 5: Designers reported that fine Manual had affected their method of teaching. When designers were asked in fine Post Module Develooment Su rvey’if designing fineir module had changed their way of teaching, the answer was yes. Three designers reported that fine experience had greatly changed fine way they teach while the ofiner three designers reported finat their method of teaching had not changed a great deal but that finey approached the process of teaching in a different way. Finding 6: The diffusion and acceptance of CBE concepts by DURC was partly attained through the co-operative developrm ent of fine Manual . As reported earlier in this dissertation, there had been resistance to CBE concepts by DURC; it was hoped that the co-operat ive * Question , Appendix E 81 develOpment of the Manual would overcome finis resistance. While the evidence is not tangible or measurable, finere are signs that CBE concepts have become more acceptable to members of DURC. The supporting evidence is as follows: a. One member of fine group has completed a module (following the Manual) which has been summ atively evaluated. b. One module is being designed for fine purposes of a Doctoral Dissertation. c. Three instructors are in the process of designing modules for their own use wifin learners. d. Seven members of the DURC group are presenting the Manual as a workshOp at fine annual convention of the American Dietetic Association. e. The Manual has been cited in a number of presentations at conventions by members of DURC. In the next chapter (Chapter V, Summary and Conclusions) these findings are further discussed. CHAPTER V SUMMARY AND CONCLUSIONS This concluding chapter has four sections (a) summary of the pilot testing of the Manual, (b) major conclusions of the study, 1 (c) heuristics related to finis study and (d) recommendations for further research . Summarlof the Pilot Testing of the Manual The purpose of finis study was to see if a self instructional Manual could be developed, for a broadly defined group, so that mermbers from that group could independently design modules for use in higher education where higher level cognitive skills were required. At least five modules were to be designed. The completed modules were to be evaluated on a criterion-referenced instrument. Designers ___ By the term "heuristic" fine aufinor takes to mean findings based on evidence of experience from the conduct of this study, which may need further verification by more scientific methods. Some of fine conclusions need to be presented as heuristic because (a) the small N upon which these generalizations are based do not allow for more definitive statements and (b) these heuristics are worfiny of furfiner consideration by other instructional developers. 82 83 were also asked to complete an attitudinal questionnaire on their perception of the effectiveness and usefulness of fine Manual as well as their reaction to the whole process of designing a module. A total of six modules were developed for finis study, three in Australia, and three in Hawaii. A furfiner module was developed at Michigan State University; it was designed and tested as partial fulfillment of a Master's Degree and was not evaluated on the criterion-referenced instrument and therefore is not reported in Tables 1 and 2 (pp.74-77). However, as the module was tested experirm entally, those findings are reported in Chapter IV and Appendix C. Conclusions of the Study Conclusion 1: INFORMATION PROVIDED IN THE MANUAL RESULTED IN THE DESIGN AND PRODUCTION OF SATISFACTORY MODULES. Of concern to educators is the frequent inability of the learner, who has demonstrated possession of certain cognitive knowledge, to transfer such knowledge into practice. The designers in this pilot study cl early transferred fine cognitive skills they acquired from the Manual to fine design and production of their module. 84 Conclusion 2: HIGHER LEVEL COGNITIVE SKILLS WERE TAUGHT THROUGH THE MANUAL. The cognitive skills to be mastered in the Manual ranged from low level discrirmination to higher order rules. Designers demonstrated acquisition and capabilities of these skills by designing and producing modules where each module included higher order rules. By judging fine evidence provided in fine designer's formative evaluation of fineir own module, it was cl ear that their subjects also reached mastery of higher order rules. Conclusion 3: THE MANUAL WAS FOUND TO BE USEFUL IN MEETING THE NEED FOR WHICH IT WAS DESIGNED. Common criteria for assessing fine usefulness of an educat- ional product such as the Manual is to question its validity, feasibility, and effectiveness . 1 . Val idity—Did the Manual do what it was supposed to do? The Manual would be considered valid if (a) designers were able to gain knowledge of key CBE concepts and infonmation from it and (b) if those concepts would result in an acceptable module. 85 With respect to fine criterion of validity, evidence in this pilot study indicated that designers did gain cognitive knowledge of fine key CBE concepts. Further, all designers produced modules which exceeded set criteria. On fine evidence avail able, the Manual was val id . 2. Feasibility--The Manual would be considered feasible if five or more college level instructors, wifin only minimal know- ledge of CBE, and geographically distant from fine aufinor, would complete modules which met fine criterion level. With respect to fine criterion of feasibility, evidence in this pilot study showed that six college level instructors, all meeting the stipulations of this study, began and completed their modules, and all met the criterion level. Tlnerefore, for fine conditions set out in finis pilot study, the Manual can be considered feasible. 3. Effectiveness--The Manual would be considered effective if (1) designers reached mastery level on key CBE concepts and (2) the modules Which finey designed and produced would meet a criterion level . 86 Evaluation indicated that on (1) there were 52 evaluations made on each designer and 312 for fine group of six. Of the total of 312 evaluations, nine were below the criterion level. Of these nine, some judgements may be reversed because of dubious validity of the test item . Because of the large number of positive evaluations (303 or more) fine Manual can be accepted as effective wifinin the design of finis pilot study as enabling designers to reach mastery level . Evaluations on (2), that the modules would meet a criterion level, were all positive. Consequently, fine Manual was effective in this pilot study. 87 Heuristics As a consequence of the development and pilot testing of the Manual fine aufinor formulated certain heuristics which may be of interest to other instructional developers. The heuristics mentioned here are only a sample (in the author's view, the most important ones). However, a large number of heuristics emerged throughout the form- ative evaluation stage of the Manual which is not a part of this pilot study and therefore not reported here. Heuristic 1: A democratic responsive development of a product is more likely to result in its acceptance. Often, in instructional development, potential clients or designers are given a model which finey are to follow. This method amounts to the imposition of a method of accomplishing goals perceived by the developer of the model rafiner than fine target population. The situation is compounded where the designer has not met the target audience and is not aware of fine particular group's concerns. In this pilot study the Manual was developed for fine expressed needs of the target population. This meant finat every word of the Manual was critically read by at least fifteen members from the target population. As a result of the feedback, areas of concern to the target population were re-written and submitted for further review until the refinements were accepted and no major concerns were found . 88 Heuristic 2: Learners are likely to closely follow a completed product. All modules develOped for this pilot study followed closely the format of the Manual itself. That is, they all used print format, incorporating many of the techniques of programmed learning. While it was suggested to fine designers that the modules which make up the Manual could serve as models, it was also stated that the format and medium of their own modules should be determined by an analysis of fine learning outcomes; on finat criterion, a number of modules should have utilized visuals, movement, and in one case, a musical instrument. It appears that the novice designer requires exam pl es of the different media mentioned in the Manual to fully operational ize cognitive knowledge. Heuristic 3: Technical terms and jargon of education should be avoided, if possible. Many of the terms used in CBE are threatening to people outside education. Often the finreat is due to an impression that the term represents technical precision, and implies an entirely new forrm of operation which required a great deal of effort for anyone unfamiliar with it. For example, the term "module" seems to arouse such fears; the term is used in other fields such as the building industry, electronics and space technology, and to add to the confusion, in education it is used to mean different things, such as a block of tirmetable or components of a school system . 89 In such a situation, the author found it helpful to introduce new educational terms finrough terms finat were already understood. For example, fine term "module" was introduced initially as a "well designed lesson". Then as time went on and exarmpl es of modules became avail able and the components of a module became known, the correct technical terrm came into more frequent and accepted use. Heuristic 4: The design of modules is a time consuming, frustrating and difficult task; only people wifin special motivation will see the task through. The aufinor knew from previous experiences and from literature that it is very difficult to get faculty members to design and report on complex modules. The fact that, for this pilot study, six faculty members started and completed fineir modules is due to a combination of factors. At the start of the project, the author developed a mental profile of the faculty member most suitable for the pilot study. The person must feel a personal need to irmprove fine quality of teaching. Such a person is usually already a good teacher and has drawn attention to him/herself for this reputation, but now is seeking further improve- ment and is looking for outside help. Usually this person is a strong scientist or researcher in his/her own field and feels a need to also be successful as a teacher. 90 Recommendations for Furfiner Research This was a pilot study. Pilot studies are used to refine a product, the methodology used and measures employed. As a result of the present study, a number of recommendations for further developrment and research can be made. These recommend- ations can be classified as (1) improvements or refinements to the Manual , and (2) improvements in the mefinods of investigation to make the findings more generalizable. Improvements to the Manual A number of improvements need to be made to the Manual. According to the feedback received from fine designers, it is necessary to include a finished product with the Manual to serve as a model. This seems an obvious point as the diffusion of innovation literature stresses the necessity for innovators to see a finished product. Research needs to be carried out as to the type of model to be provided, for example, should it be 51 ide/tape, print, video, or a combination. Would a model using one medium influence designers to design similar medium modules? What should the length of the model be? Would a lengthy model encourage similarly lengthy products? How elaborate should fine model be? How does a costly, professionally designed and produced module affect the beginning designer, for example, would it be threatening or would it be motivational? 91 Designers commented on fine presentability of the Manual. The point was made finat the total number of pages approaches 300 and it is difficult to find a section of interest without spending a lot of time searching. Suggested changes include fine use of colored pages according to a code, e.g. white paper denotes conceptual background information, green paper for the seven steps of the model and so on. Another improvement could be the use of plastic tabs attached to fine different sections which would act as "thumb tabs". One unanswered question concerns the adequacy of fine Manual; is all the necessary material avail able in the Manual? The evidence indicates that designers need to go to further outside sources for more information. The author considers this to be acceptable; to include everything that is possibly required in fine Manual would make it a frightfully heavy volume. In the present Manual finere are a lot of references to which the designer could turn for furfiner information. However problems cwld arise where the references are not avail able, particularly in another country. Designers also pointed to a few typographical errors, areas where improvements in expression are needed and a total of three missing pages . The obvious shortcomings in the Manual need to be corrected and further development cycles could look into the question of the amount of inforrmation included. Further research should also look at 92 the different styles of expression used in the Manual. At the present, the styles are varied, ranging from harangues to adopt different attitudes, to hum or, to matter-of-fact presentations of research findings. Generally there were insufficient comments on the construction, content and presentation of fine Manual itself, possibly because such information was not actively sought by the author. Further develOp- ment cycles need to solicit more feedback frorm the designers . Improved Methods of Investigation There is a need for better evidence on the validity, feasibility and effectiveness of fine Manual. The mefinods used in this pilot study provided tentative evidence until the next cycle of refinement. In fine next cycle of refinement the following areas could be considered. Val idity.-- The validity of the evaluation items (in Appendix A) should be further studied to see if they correspond with, and consequently measure, the content of the Manual. Further, do the evaluation items accurately measure fine designer's knowledge and product? It seems that evaluation item VI A in particular needs to be further tested . The validity of pre and post test items, throughout the Manual need to be established. 93 Feasibil ity.--One area to be further researched is fine feasibility of the Manual as a self instructional entity. In this pilot study fine six designers were guided to some extent by corresponding wifin fine author where they were constantly encour- aged to keep to their time lines and complete their modules. However, without this constant monitoring would the designers carry on their task to completion? What factors could be built into the Manual which would ensure completion, e.g. the effect- iveness of tirme lines designed into fine Manual for purposes of self pacing? Effectiveness.-- In the next cycle of research and develop- ment better measures of effectiveness need to be used; measures which can provide better quantitative evidence on fine effectiveness of fine Manual . Two areas are of immediate interest. One area concerns the designer's knowledge gain and clnanges in attitude measured finrough pre and post test results. Such measures ShQJld provide clear data as to the designer's knowledge of key concepts and attitudes towards CBE, for pre and post treatment comparisons. The second area is the effectiveness of fine modules produced by the designers compared to traditional teaching methods . The experimental design presented as Appendix C is a possible guide to such experimentation and deserves replication. 94 Concl udigRemarks The Manual provides fine cognitive skills and fine procedural guidelines for fine design and development of a module. Two additional features of fine Manual are (1) that it is self instructional and (2) finat it particularly addresses the acquisitionofhigher order skills. The development of the Manual was through responsive interaction with a particular target group (college level instructors with minimal CBE background) where this author attempted to respond to the needs of finat group. In this pilot study, the Manual has been successful; it is now ready for a further cycle of development and evaluation. In this next cycle, summative evaluation in the form of comparing perform- ances of control and experimental groups should provide further data as to fine validity, feasibility and effectiveness of fine Manual . It is hoped that fine product (the Manual) and the principles used in its develOprment will prove useful to educators who are sufficiently concerned with the needs of learners to engage in fine learning and growth process finemselves.

Instructional Goal A. The designer should clearly indicate the rationale for selecting the topic for their instruction. The rationale should include such items as their expertise in the content area, ability to provide the instruction within a reasonable amount of time, the availability of students to try out the materials in the formative evaluation, and the need for this type of instruction. The goal statement should be a clear indication of the outcome of the instruction. Although the goal does not need to be stated in precise behavioral terms, it should reflect, in general, what students should be able to do when they have completed the instruction. ll. Instructional Analysis A. The designer should indicate which instructional analysis methodology has been chosen and why it was selected. The designer should include a complete instructional analysis chart that lists all the subskills associated with the instructional goal. The subskills should be stated in behavioral terms. Entry behaviors should be included on the chart and clearly indicated as such. The designer should describe the diagram previously described in B and indicate the relationship of the subskills to each other. ll6 ~ The designer should describe the entry behaviors that have been identified and explain the rationale for including them. For instruction that has no relevant entry behaviors, students should explain why none are required. Ill. Description of Target Population A. The designer should describe the general characteristics of the target population for whom their instruction is being prepared. The target populations may vary from a particular classroom group to a national category of students. Important aspects of this component are that the target population is identified and that there is some statement of the implications of the relationship between the general characteristics of target students and the instruction to be provided for them. IV. Performance Objectives A. The designer should include in the documentation report a chart that indicates in one column the subskills and instructional goal as identified in the instructional analysis and in a second column, the corresponding performance objectives and terminal objective for the instructional unit. Subskills and objectives should be numbered similarly in order to indicate their relationship. The objectives for the instruction should be stated using the three components suggested by Mager. These include the conditions, performance, and criteria. The alternative approach to writing objectives suggested by Gagne and Briggs is also appropriate. Student should indicate which format they have used for the objective statements. ll7 V. Criterion-Referenced Tests A. The designer should provide a clear indication of the relationship between their test items and their instructional objectives. This relationship can be indicated by assigning the same numbers to test items as was used to number the corresponding subskills and objectives, or, a chart can be developed which indicates the item number of each performance objective and the corresponding test items. The designer should indicate the criterion used to judge the mastery level of learners' performance relative to each of the objective and to the total test. After reviewing the test, the instructor should determine if there are adequate number of test items and whether the items are appropriate for the target population and the content of the instruction. VI. Instructional Strategy A. The designer should describe how their instruction will motivate learners, inform them of what they are going to learn, and remind them of related information which they already know. The designer should describe how the content will be presented to learners. This explanation should not simply be a running description of the specific content, but rather an indication of how ”chunk" size will be determined and sequenced. A description should be included of the activities provided to learners to practice the behavior taught in the instruction. The provision of feedback for learners' performance should be described. ll8 The evaluation of testing strategies was discussed previously in Section V. Although the designer is not typically required to develop any remedial or enrichment activities, a brief description of suggested ones should be included. After examining the instructional strategies described by the designer, the instructor should examine the instructional unit itself to determine whether the materials are consistent with the strategies described by students in their documentation sections. VII. Formative Evaluation A. The designer should describe the preparation of instruction for the one-to-one formative evaluation. This description should include the format of materials to be evaluated, the characteristics and entry behaviors of learners who participated in the evaluations, the criteria for the selection of the learners, and the procedures followed in conducting the one-to-one evaluation. The designer should describe the results of the one-to-one evaluation, particularly the major comments received from learners during the evaluation. There should be a description of the types of revisions made in the materials and the rationale for these revisions based on the results of the one-to-one evaluation. The designer should provide a complete description of the characteristics and entry behaviors of learners who participated in the small-group evaluation. There should also be a complete description of the procedures employed in l19 implementing the evaluation. The description should include the format of the materials, the procedures which were used for testing, the instructions given to learners, and the feedback received at the end of the instruction. There should be a description of all instruments and procedures used to collect data. These descriptions can be used to document the effectiveness of the instruction and to identify points in the materials that still need revision. Students should summarize the data collected, including the display of such items as pretest and posttest performance, performance on embedded-test items, learning time, performance by objectives, and learner attitudes as indicated on questionnaires. VIII. Suggested Revisions A. The designer should describe, based on the data and information gathered during the small-group evaluation, the revisions which remain to be made in their materials. The relationship between these revision recommendations and the data obtained during the small-group evaluation of the materials should be apparent. The designer should indicate revisions that remain to be made in the test instruments as a result of the data and information gathered during the small-group evaluation. The designer should indicate any instructional procedures that need to be revised as a result of information gathered during the small-group evaluation. They should describe any changes in procedures or materials needed if materials were used in a regular classroom setting. ll9/l Criteria for Evaluating Designer-Prepared Instructional Materials l. Materials should include objectives, pretests/posttests, and the instruction. 2. The instruction should follow the instructional strategy established for the unit as described in the documentation report. Some general guidelines: a. Have adequate motivation and attention getting ideas been provided for the content to be taught and the characteristics of the target learners? Have learners been informed of necessary prerequisite knowledge or skills? Have students been informed about what they will be learning to do (common language objectives)? Have ideas and concepts been presented in a logical sequence? Is enough explanation provided for pupils to actually ”learn" the ideas, concepts, and skills? Are accurate and adequate examples included of ideas, concepts, and skills being taught? Are there embedded tests to provide pupils with the opportunity to practice skills? Is adequate and accurate feedback provided to pupils responses to the embedded tests? 3. Are materials legible, clear, and easy to follow? 120 It may be expected that the instructional materials will be prototype or first drafts that are inexpensively produced. Drawings and illustrations should be stick figures or magic marker drawings and materials should be inexpensively duplicated. This ”draft” nature of the materials should not detract from the students' evaluation of their materials. The important issue is that the materials include the information on the right pages, and in the right order, so that it can be tested with target learners, analyzed, and revised before being produced in a more polished format.

Also an achievement at the Mastery level of ninety percent accuracy on the posttest would indicate that the dietetic student can apply Problem-Oriented Medical Record (POMR) knowledge into accurately writing a dietetic problem, plan of action and SOAP progress note. IZS 126 When the hypothesis predicts that differences will exist in the data and allows this difference to be in either direction (larger or smaller), a two-tailed test of its null hypothesis is performed since the difference can fall in either tail of sampling distribution (Nie et a1., 1975). The T-test provides the capability of computing whether or not the difference between two sample means is significant. Two types of tests may be performed. 1. Independent samples: the cases are classified into two groups and a test of mean differences is performed for specific variables. 2. Paired samples: for paired observations arranged casewise, a test of treatment effects is performed. An example would be the same (or similar) individual being measured before and after treatment. The goal of the T-test statistical analysis is-to establish whether or not a difference between two samples is significant. "Sig- nificant" is used to mean "indicative of" or "signifying" a true dif- ference between the two samples (Nie et a1., 1975). A significance level for testing the null hypothesis was chosen and set at equal to or less than .05. This significance level is exactly the probability of rejecting the null hypothesis when it is true (Nie et a1., 1975). If it is known whether the two populations have the same vari- ance, an F test of sample variances may be performed. The null hypo- thesis with alternative hypothesis and a significance level a' is chosen. An a' level of .05 was chosen. From the sample variances, F was computed. If the probability for F is greater than a', the t value based on the pooled-variance estimate is used to determine probability. 127 If the probability for F is less than or equal to a', the t value is based on the separate variance estimate to determine probability (Nie et a1., 1975). Results of Hypothesis Testing Each hypothesis is presented along with a report of findings. Five of the protests of the Michigan State University Conventional Study Plan Dietetic Students were misplaced so the data from these students could not be included in the analysis of data. Hypothesis A: Dietetic students at MSU and the University of Hawaii given a self-instructional module or equivalent lecture presen- tation to learn the application of the POMR concept to client nutri- tional care will show no gain in score from pretest to posttest to indi- cate that learning has taken place. This hypothesis was tested using the dependent T-test. Results are reported on Table 1. Findings: The null hypothesis was not supported. There was a significant gain from pretest to posttest for all groups (a < .001). The pretest scores for both treatments showed greater deviation compared to the deviation in the posttest scores, which may also indicate that more students learned the POMR concept in an equivalent manner. Hypothesis 8: Dietetic students at MSU receiving the self— instructional module on POMR will not show a significant difference in achievement on the posttest compared to dietetic students at MSU given an equivalent lecture presentation on POMR and same posttest. This hypothesis was tested using the independent T-test.

Results are reported on Table 2. Findings: The null hypothesis was supported. The difference in achievement on the posttest scores for the module and lecture groups was not significantly different. Further analysis revealed that the Conventional Study Plan students in the module group had the lowest standard deviation. The Coordinated Study Plan students in the module treatment may have been a more homogeneous group. The pretest scores were analyzed at the same time the posttest scores were analyzed and so were also included on Table 2. There was a significant difference in pretest scores between the lecture and module groups of the MSU Coor- dinated Study Plan students (.001) whereas pretest scores in the lecture and module treatments for the MSU Conventional Study Plan students were notrsignificantly different. Hypothesis C: Dietetic students at Michigan State University receiving the self-instructional module on POMR will show a significant difference in achievement on the posttest compared to dietetic students at the University of Hawaii given the same self-instructional module and posttest. This hypothesis was tested using the independent T-test. As the dietetic curriculum had two offerings, the Coordinated Study Plan and Conventional Study Plan, the data were collected separately for students enrolled in each plan. Results are recorded on Table 3. Findings: The null hypothesis was not supported. The differences in achievement on the posttest percentage mean scores were not significant. 130 .pom: mm: oumsnumo oocmnno> pudendum < .moms mm: unmanumo oonmnne> ponoom < o n .8. v a n... nfiunmnemnmm mam.n man. was.~ nmc.~ nonno enmecmnm mnm.a mme.~ oao.v ons.e connmn>oe unneemnm poem. an kn.n owmv.nm ooov.ew omen. km.nn mn.n ooom.mm ooon.~m can: . umouumom men.v eso.~ Nan.m onm.m nonnm enmeemnm nso~.nn ncm.n Nmo.n one.On connnn>oe enmecmnm mnnm. en vo.n nmm~.mn cocv.me pence. wn ma.m ooom.mv ooo~.oo can: amouona Anuzd nonuzv amaze Acnuzd .nonn we osnm> .>:ou .>:oo .>:ou .enoou nnmn-o3n n nnaza: .amz nnmzn: am: nmon cameo: onsuooq I4 .mncopsum team xpsum m.>:ouv fineonuco>cou one a.onooov moumtnmnoou xuwmno>nca madam damage“: you nanoseconh onsmoz mom onsuooq toosuom monoom coo: ommucoonon amonnmoa en ooeonommna new unsound an outonommfla now swoon? u:op=odom:~--.~ unnoh 131 41 .mom: was oqunumo oocmnnn> ounnmmom <0 .mom: was unmanumo ooconno> monooa < a .mo. v a nu ncmunnnnmnma mma. mam.m mam. mnn. nonno enmecmnm mno.m mnm.m mno.m ~ms.n connmnsoe enmenmnm owns. nm.o as. nooo.mm owne.nm omen. mm on.n noeo.ma ooom.mm can: nmonnmoa nan.m men.v nan.m osc.~ nonno enmenmnm «so.Vn nvo.nn svo.sn nom.m connmn>oe ennecanm gene. on mm.n ooo~.mo nmw~.mn namno. mn nn.~ ooo~.mo ooon.mv can: umoumhn— Amnuzd Anuzd Amnuzd nonuzd nmon .nonn we o=Ho> .>:ou .>:ou .>:ou .mnoou nnan-ozn n nnazm: am: nnmzn: am: unspoz cameo: .mutomsum tend nesum a.>:ou nnmzmzv nmconueo>eou nnmzmz mo nunmno>ncs onu new mucoosum unnouono tend nusnm fi.>:oov unconnco>cou men n.mnoouv pounenpnoou nunmno>nta oumum townnon: now utosumonb onsmoz :n monoom one: ownncoonoa anonymod en coconoMMnn can «monond :n ooconomwno now unease utomeomomcnuu.m once 132 Further analysis (Table 3) revealed that the pretest percentage mean scores of the Michigan State University Coordinated Study Plan students and the University of Hawaii Conventional Study Plan students were significantly different (.013). In comparing the Conventional Study Plan students at Michigan State University and the University of Hawaii Conventional Study Plan students, it is seen that neither their pretest or posttest percentage mean scores were significantly different as also seen on Table 3. The dietetic students at Michigan State University and the University of Hawaii achieving ninety percent on the posttest are recorded on Table 4. The majority of students in each group achieved the ninety percent criterion level. Reliability of Posttest Evaluators The calculation of a Reliability Coefficient was used for esti- mating the reliability of the two independent evaluators of the posttest (Ebel, 1972). The formula is: anyg- Zx§y r: Jlnzxz - (EX)21.[n£y2 - (XX)21 The results of the formula indicated that the reliability coefficient was .69 indicating that the two evaluators had sixty-nine percent reliability. The score can range from zero to one with scores near one indicating high reliability between raters. l33 Table 4.--Number of Dietetic Students in Lecture and Module Treatments of Conventional and Coordinated Study Plan Students at Michigan State University and the University of Hawaii Achieving Ninety Percent on the Posttest.

They felt that more time was needed to be Spent on the Assessment Component of the SOAP Progress Note and less time on learning about Dietetic Problems. The students felt that they derived benefit from the embedded test questions while going through the module. The affective aspects of the module (music, cartoons and statements about their success, e.g., You're Doing Fine!) were enjoyed by all of the students and recommended to be left in the module. The dietetic students at the University of Hawaii thought that the cartoons of lesson two of the module needed to be more relevant to the content. Students reported there was confusion when they had to move back and forth between the slide tape and student booklet but this confusion decreased as the student kept going through the module. Also clarity as to whether or not only one answer is acceptable for the embedded test questions is needed. Those students attending the lecture treat- ment felt that the lecture was lengthy and repetitious but that the case study examples used were helpful. The students overall felt that they learned how to write SOAP notes in the correct format. l35 CHAPTER VI CONCLUSIONS/RECOMMENDATIONS Conclusions Major conclusions from this study concern Hypotheses A, B and C. Null Hypothesis A states that dietetic students at MSU and the University of Hawaii given a self-instructional module or equivalent lecture presentation to learn the application of the POMR concept to client nutritional care will show no gain in score from pretest to posttest (both tests measuring equivalent content) to indicate that learning has taken place. Hypothesis A was rejected since there was a significant gain in score from pretest to posttest to indicate that learning had taken place. Null Hypothesis B states that dietetic students at MSU given a self-instructional module to learn the appli- cation of the POMR concept to client nutritional care will show no significant difference in achievement on the posttest compared to dietetic students given an equivalent lecture presentation to learn the application of the POMR concept to client nutritional care and same posttest. Null Hypothesis 8 was accepted since there was not a significant difference in posttest percentage mean scores between the module and lecture groups in either the Coordinated Study Plan or conventional Study Plan dietetic students at Michigan State University. Null Hypothesis C states that dietetic students at MSU given a 136 self-instructional module to learn the application of the POMR concept to client nutritional care will Show a significant difference in achievement on the posttest compared to dietetic students at the University of Hawaii given the same self-instructional module to learn the application of the POMR concept to client nutritional care and same posttest. Null Hypothesis C was rejected since the posttest scores of the dietetic students at the University of Hawaii receiving the module treatment were not significantly different than the posttest scores of the Michigan State University dietetic students in the module groups. The University of Hawaii's dietetic students' high posttest scores may be accounted for by the fact that they were being offered an opportunity to participate in'a project being offered by another large mainland university. These students could have developed interest and curiosity with a desire to perform well. Forty one of the forty seven students (93%) participating in this study were able to achieve at the ninety percent criterion level on the posttest regardless of being in the lecture or module group. Over ninety percent of the University of Hawaii dietetic students achieved ninety percent on the posttest which may indicate that the POMR module has the potential of being used with other dietetic programs with their students achieving the ninety percent criterion level on the same posttest. The raters of the posttest for all groups showed a sixty nine percent reliability coefficient between each other. The use of the performance criteria checklist used in scoring the posttests probably I37 accounted for this reliability and further clarification of the criteria may yield higher results. Recommendations A major recommendation would be that the module be revised for clearer understanding based on the comments of the students. The whole module is being reviewed by the designer's Graduate Committee Members and Clinical Faculty of the Coordinated Study Plan in Dietetics at Michigan State University in order to convert it from a prototype into a Professional Instructional Module. A self-instructional module should be produced using a content area that does not change frequently in order to have the time spent in design and production worthwhile. Evaluation of more pre- and posttests of the module with'more dietetic students could be conducted to increase the validity of the module. It appears that the hierarchical process used to develop a final learning outcome (Hiob, 1978) has application for other types of cogni- tive learning in order to develop a sequential path leading the student to mastery of a subject. 'This thesis study has shown that the hier- archical process is successful in aiding the dietetic student in learning the application of the POMR concept to client nutritional care and, in the designer's opinion, be applied to the develOpment of other materials in the cognitive domain in dietetic curriculums.

A number of people have been very supportative throughout this project, especially Professor B. Wenberg, together with the faculty and graduate students of the Department of Food Science and Human Nutrition at Michigan State University Many of the modules in this Manual have been adapted from existing materials. Whenever possible, permission to adapt the original materials has been sought from authors when they could be identified. Two sources of materials need further acknowledgement: first, unpublished material acquired mainly as class notes at Florida State University, especially the text The Systematic Desigp_of Instruction by Walter Dick and Lou Carey (roneod) which has subsequently been published by Scott, Foresman and Co., Glenview, Illinois (1978) under the same title; and second, unpublished materials from various sources at Michigan State University, particularly from Dr. C. Gentry's classes. Many people have contributed in providing suggestions and testing the Manual -- to all these people I wish to express my gratitude. IllO WELCOME This is a self instructional Manual on how to design and produce modules. It has been formatively tested and is currently going through wider field testing . The author would be grateful for comments and suggestions to the further improvement of this Manual . The Manual is made up of a series of modules . You are asked to work through them all. Tests in various forms through- out the Manual will give you an indication of your progress; there may be a number of modules which you can skim through while others may need considerable concentration. The more effort you put into your work the greater will be your reward (anon. ). 141 Introduction The use of individualized self instructional programs is growing faster than any other method of improving instruction (Cross 1976). The reason for this focus is quite simple: students differ along numerous dimensions and well designed individualized instruction considers these individual variations and attempts to provide for them. The effectiveness of individualized instruction has been demonstrated in a large number of studies (Kulik 1974, Keller 1968). What is individualized instruction? If asked, each reader could probably provide a definition of individualized instruction and believe it was fairly accurate and reflective of the current thinking of most educators about individualization. However, if these definitions were shared, it would be found that there are almost as many definitions of individualized instruction as there are persons using the term. Current definitions vary from those which indicate that students will proceed at their own rate through a prescribed set of materials to reach a predeter- mined set of objectives, to definitions which indicate that students will be free to select their own means of achieving their own objectives. These two types of definitions reflect in part the two traditions which have contributed the most to the growth of individualized instruction. These two approaches may be characterized as the humanistic approach and the behavorial science or systems approach. 142 Educators who consider themselves in the humanistic camp have a genuine interest in the total development of individual children. They recognize the importance of individual differences and believe that the essence of an outstanding education is the display of genuine care and concern for students as they attempt to define those areas of learning which.are important and relevant to them. There is a strong focus on the personal growth and development of the individual student. This emphasis on individual personal development and human relationships is an attempt to counteract the increasing alienation which students encounter in their society and perhaps in their own homes. The rapid growth of the book sales in the personal development area and the establishment of various personal development groups reflect our society's interest in these same problems. Those.educators who favor the behavioral science or systematic approach to education have also had a significant impact on the individ- ualization of instruction during the past decade. This approach emphasizes the consideration of the inputs, processes and outputs of the education process. Research has been conducted on how to identify content for inclusion in the curriculum, how to better assess the knowledge and abilities of students, how to better design classroom procedures and in- structional materials, and how to make instruction more effective. The systematic approach to instruction had its initial impact in the development of programmed instruction. This medium of instruction emphasizes the importance of a precise definition of what it is that the student will learn and the importance of careful structuring of in- structional materials. Programmed instruction utilizes active student participation in instruction to facilitate achievement of given objectives. iMany of the teaching principles of programmed instruction are applied 143 today in the systematic design of instructional materials, although programmed instruction per se is not in great use. Both of these instructional approaches - the humanistic and the systems - emphasize the significance of individual differences and the necessity of providing appropriate instruction to the student. Self Test After each of these statements write (H) for humanistic or (S) for systematic approach: 1. Programmed learning is an example of which major approach? ( ) 2. Behavioral science prefers an approach which is ( ). 3. A precise definition of leaning is a feature of ( ) approach. 4. Personal growth and development of the total individual is the major concern of ( ) approach. m It should be noted that while in academic circles representatives of humanism and behaviorism debate the merits of their approaches, there is little evidence of this conflict when one views individualized instruction in use in classrooms. Recent studies by Fox and DeVault (1974) have indicated that the best examples of individualized instruction are those which blend the best of both the humanistic and the systems approaches to instruction. While the MSU dietetic model will advocate the behavioral science approach to designing, developing, and evaluating instructional materials, the authors are in full accord that humanistic and systems approaches must be integrated to provide the best atmosphere for effective student learning. Feedback: 1. Systematic 2. Systematic 3. Systematic 4. Humanistic IAS There are three major components in the implementation of individ- ualized instruction. The first involves the role of teachers; the second is the preparation of instructional materials; and the third is the delivery of instruction to students in the classroom. With the emphasis on selfinstructional materials, the instructor no longer plays the role of disseminator of all information. However, it is not totally agreed upon as to what the new role of the instructor should be. In some settings the instructor's role has been downgraded to a scorer of test papers and in others it has been upgraded to a general learning consultant to students. Clearly this is an area in need of continuing research because of the tremendous implications for the total instructional setting. Instructional designers who are preparing materials for use in individualized systems have neither ignored the role of teachers nor have they had it as their major concern. Their central purpose has been to identify those objectives that are to be achieved and to design instructional strategy and evaluation techniques that are employed. Therefore new materials designed specifically for selfinstruction are needed. The third area of concern is the delivery of instruction. A delivery system is defined as the integration of the instructor, students, and the instructional materials in a given setting in order to bring about the desired learning outcomes. 'Various individualized delivery systems have been developed, and teachers have implemented methods for meeting the needs of their students which reflect the instructor's preferred styles of teaching. No one pattern has universally emerged as the best and most appropriate one. l46 Modular Instruction The types of instructional materials which are typically used in individualized instruction have come to be referred to as modules. Just as there is no universally accepted definition of individualized instruction, similarly there is no general definition of a module. An analogy may help in this explanation of what constitutes a module. Consider the technique known in the building industry as modular construction. Various components of a building are constructed in a factory and shipped to the construction site. These modules are then placed together in a particular configuration that results in the construction of a new building. Workers are still required to drive the nails and place the screws and bolts which hold the entire structure together. They also pour the foundation and add the finishing touches which make it a sound and secure building. Modular instruction may be considered in much the same way. A module is a selfcontained or selfinstructional unit of instruction which has an integrated theme, provides students with information needed to acquire specified knowledge and skills, and serves as one component of a total curriculum. Most instructional designers would agree with the definition given above. However they would differ on a number of the specific characteristics of modules. For example, the length of time required for students to study a module may vary from say one to fifteen hours. Some designers will insist that a module of instruction should include at least two alternative presentations of the instructional materials and preferably two or more modes of presentation to accommodate individual differences. 147 In addition, some designers would argue that a module should be strictly self-contained. That is, a student should be able to achieve all the objectives which are stated in the module without interacting with the teacher or other individuals. Other designers will specifically include in the design of the module the participation of peers, teachers, and outsiders in order to involve the student in a variety of interactive activities. . Designers even differ on whether students should be informed of the major objectives for a module. Some designers insist that students should receive precise statements of the objectives for a module while others argue that objectives may be rewarded at a level more appropriate for the student, or that objectives may be omitted all together. Regardless of the issues listed above, most modules involve some type of active participation by the student in terms of interacting with the instructional materials rather than being a passive reader of the materials. The student is asked to perform various types of learning tasks and receives feedback on that performance. There is some type of testing strategy which indicates to students if they have achieved mastery of the content, and what they should do if they have not yet achieved mastery. Based upon the description of prior paragraphs, how would you recognize a module if you saw one? In its most simple form, a module might be a typewritten statement to students which indicates what it is they are about to learn and how they will be tested. It would provide printed or typed instructional materials as well as some practice test items. A self-test which might be used prior to taking a terminal test could also be included. The most complex module might contain all of the items listed above, but also incorporate a number of alternative sets of materials from which the student might choose and the most appropriate one for him or herself. 148 Alternative media forms such as an audiotape or a filmstrip might be included. In addition, the student might go to a laboratory to conduct an experiment or go outside the school to gather information. Regardless of the simplicity or complexity of a module, it should be validated, that is, it should be demonstrated that students learn from it- that they can perform the skills as described in the objectives for the module. Methods have been developed which are used to obtain information from.students as a module is being developed to improve the quality of the module. After the module has been completed, data is collected which is used to demonstrate the extent to which the module is effective in bringing about anticipated changes in student ability. A. Judge the following statements as True or False 1. Most modules require active interaction by the student with instructional materials. 2. Tests are an important part of a module. 3.

What is a module? Do you agree with this definition: a module is a self-contained or self-instructional unit of instruction which has an integrated theme, provides students with information needed to acquire specific knowledge and skills and serves as one component of a total curriculum. Feedback: 1. (b) 2. (d) 3. (c) 4. (d) 5. False 6. Yes 151 The focus of this Manual is on learning. We will constantly ask the question "how does the person learn?" This approach differs markedly from the usual "how will I teach?" Well then, how does the person learn? The answers are provided in this Manual , starting with the next module on how we process information . 152 Our Model Given the need to develOp individualized instructional materials and being acquainted with the systems concept, what should we do next? One seemingly reasonable approach would be to use an already existing module as a model . There are several prob- lems associated with this approach. Any given module is designed to teach a particular type of learning to a particular type of student. What is needed is a more generalized model - one which will describe the procedures for developing a module regardless of the type of learner or the type of learning which is to occur. One general model for designing instructional materials is referred to as the systems approach model. It must be emphasized that there is no single systems approach model for designing instruct- ion. There are a number of models which bear the labs "systems approach, " and all of them include most of the same basic compon- ents. The systems approach model which will be presented includes the major components which are included in other models. The systems approach models are an outgrowth of over 20 years of research into the learning process. Each component of the model is based upon theoretical and/or research outcomes which demon- strate the effectiveness of that component. The model brings to- gether in one coherent whole many of the concepts which you may have already encountered in a variety of educational situations. The model is graphically presented on the next page. It includes six interconnected boxes. The boxes (each step) refer to sets of pro- cedures and techniques which are employed by the instructional des- igner to design, produce, evaluate and revise an instructional module. 153 6980 2282 not moose 0:8an .3.m..2 ect.}; 8:9”. to:n:_o>o til...

This recent research has generated a body of theory that explains how people take in information and how they organize information in memory. These activities of assimilating and arranging information are known collectively as information processing. By and large, researchers agree that human perception and human memory impose rigorous organization on what is learned and on how it is learned. Concepts are not stored randomly, but rather are related to other similar concepts in clusters, which in turn are related to other clusters of concepts. The whole forms a logical and often measurable cognitive structure. In addition, it is generally agreed that cognitive structures are changed when new concepts are learned, and also that they in turn act upon those new concepts to make them.more congruent with existing structures. What we learn changes what we know and what we know changes what we learn. The interesting question to ask now is: What is it that goes on inside the student's head when he learns? What is the process of learning like? Comtemporary theories conceive of learning as a matter of information processing. Stimulation from the learner's environment affects his central nervous system by a series of processing stages. The transformed information is stored in memory, and a final transformation makes possible a performance that is evident to an external observer. A 'more-or—less standard model employed in these theories is onlnext.page: .2 .m .wnmmo sonACIId 0...:me \\\I/J Aswan .mmonm nowhnn .nOnpopnumnH non mcncnmoq no maunucommm 155 m m m m n > o :85: o“ m w Iv 25» o m m n . ml .505 m o z :85: m m u m Fllml m .2 257023 _II. 2 11 o m m _ . _ r 5.252% o > _ x o ,Illv m I mmzoemum u a a o o e o . o o . C r mw.UZ.hDUmeL 156 (l) A.number of contemporary learning theories treat learning and memory as informationeprocessing, deriving their constructs from.computer science and linguistic theory, as well as from psychology. Atkinson and Shiffrin, 1968; Linday and Norman 1972. We use Atkinson-Shiffrin as an example of the general model. This is the way the model works. Stimulation from the learner's environment affects his receptors and enters the nervous system via a sensory register. This is the structure responsible for the initial perception of objects and events that the learner sees, hears, or otherwise senses. The information is "coded" in the sensory register, that is, it has the form of a patterned repre- sentation of the original stimulation. The information remains in this form for only the smallest fraction of a second. Entering the short-term memory, the information is again coded, this time into a.conceptual form. Thus, a figure like X becomes a representation such as an "X", a figure like 2 becomes the concept "two". (not the word two). Persistence in the short-term memory is relatively brief, a matter of seconds. However, the information may be processed by internal rehearsal and thus preserved in the short-term memory for longer periods. Rehearsal may also play a part in another operation; if the information is to be remembered, it is once again transformed and enters the long-term memory, where it is stored for later recall. ‘Most theories assume that storage in long-term memory is permanent and that later failures to recall result from difficulties of "finding" the information. It is important to note that the short-term and long-term memories may not actually be different structures, but only different ways of functioning of the same structure. Notice also that information that has passed from.the short-term memory to the long-term memory may be retrieved 157 back to short-term memory. The latter is sometimes spoken of as the "working memory" or the "conscious memory". When new learning depends partly on the recall of something that has previously been learned, this something must be retrieved from long-term memory and must re- enter the short-term memory. Information from.either short-term or long-term memory, when retrieved, passes to a response generator, which has the function of transforming the information into action. The neural "message" from this structure activates the effectors (muscles), producing a performance which affects the learner's environment. This action is what enables the external observer to tell that the.stimalatinnfhasohad its expected effect-that the "information has been processed", and the learner has indeed learned. A very important set of structures has yet to be described. These are labeled executive control and expectancies. Signals from these structures are presumed to activate and modify the flow of information. For example, the learner has an expectancy of what he will be able to do once he has learned, and this in turn may affect how an external stimulus is perceived, how it is coded in memory, and how it is transformed into action. Control processes originating in the executive control structure may determine how the information is coded when it enters long-term memory and how the search and retrieval are conducted for recall, among other things. (References to various theoretical accounts are: Atkinson & Shiffrin, 1968; Norman, 1970; Anderson & Bower,.l972; Lindsay & Norman, 1972). 158 Quiz According to modern learning theory, stimulation from the learner's environment affects his sense organs, and is transformed to patterns of neural "information" which are held for very brief periods in this form. What is the structure called that performs this function? A learner has acquired and stored the skill of expressing ounces as pounds and fractions of pounds. Some days later, he is required to use this skill in comparing the contents of cans of coffee. In re- calling the skill, what process is involved?. In the example of 7, if what has been learned is stored in Long-term Memory, to what structure does it fow, when recall occurs? 0......00.....0...0.00000000000000000000000000000000000COOOOOOOOOOOOO This is the most widely accepted information processing model.

Unfortunately there do not seem to be .a_nx successful programs in Operation which are entirely competency based. It seems that a CBE program is too complex and radical to be fully implemented and accepted. This Manual follows many concepts of CBE, however it prefers to learn from realities Of the world and therefore picks and chooses. A reasonably accurate label for this Manual is to say that it is "mastery based". The two following modules will acquaint you with this all important concept of mastery and m astery learning .

MASTERY LEARNING The most wasteful and destructive aspect of our present educational system is the set of expectations about student learning each teacher brings to the beginning of a new course or term . The instructor expects a third of his pupils to learn well what is taught, a third to learn less well, and a third to fail or just "get by". These expectations are transmitted to the pupils through school grading policies and practices and through the methods and materials Of instruction. Students quickly learn to act in accordance with them, and the final sorting through the grading process approximates the teacher's original expectations. A pernicious self-fulfill ing prOphecy has been created. Such a system fixes the academic goals of teachers and students. It reduces teachers' aspirations and students' desires for further learning . Further, it systematically destroys the ego and self-concept of a sizeable proportion Of students who are legally required to attend school for ten to twelve years under conditions which are repeatedly frustrating and humiliating. The costs of such a system in reducing student Opportunities for further learning and in alienating youth from both school and society are too great to be borne for long . Most students (perhaps over 90 per cent) ga_n master what we teach . Our basic instructional task is to define what we mean by 165 mastery Of a subject and to discover methods and materials to help the largest proportion of our students reach it. --Benjamin S. Bloom Human Characteristics and School Learning, McGraw Hill, N.Y., 1976. I66 Introduction . Currently the strongest movement is the development of instructional programs to meet individual student needs. This is not a new theme but it has only been in the last decade, with developments in Technology and the systems approach, that such programs have been implemented on any large scale basis. The basic argument in favor of individualizing instruction comes from a multitude of research and evaluation studies that suggest student differences in interests, motivation, learning rate, goals, and capacity for learning, among other things; and, therefore, group-based instruction on a common curriculum is inappropriate to meet their educational needs. In addition, present group instruction practices fail to help the student to cultivate a sense of responsibility for his educational, personal , and social development or to make realistic educational decisions and choices about his future. The trend toward individualization of instruction has resulted in the development of a diverse collection of attractive alternative models. In this paper I will discuss Mastery Learning and allude to Individually Prescribed Instruction (IPI) and Program for Learning in Accordance with Needs (PLAN). For descriptions of IPI see Glaser 1968,1970, and for PLAN see Flanagan 1967,1971 . 167 The mastery learning concept was introduced to American schools in the 1920's with the work of Washburne (1922) and others in the format of the Winnetka Plan. The program flourished in the 1920's; however, without the technology to sustain a successful program, interest among developers and implementers steadily diminished (Block,1971). According to Block (1971), mastery learning was revived in the form of programmed instruction in the late 1950's in an attempt to provide students with instructional materials that would allow them to move at their own pace and receive constant feedback on their level of mastery. But programmed instruction was not effective for all students, and so, in an attempt to handle individual differences better, Bloom (1968) and his students (Airasian, 1971; Block, 1971) improved on the standard programmed instruction model by combining it with a model of school learning developed by Carroll (1963, 1970). Carroll's model of school learning provided the conceptual framework for more effective handling of individual differences within an Objective-based curriculum . In brief, Carroll's model states that the level of mastery reached by a student on any instructional task or school Objective is a function of the time actually spent learning the material and the amount of time he needs to master the material. The amount Of time a student actually spends learning the material depends on two factors - 168 time allowed, and his perseverance. The amount of time needed by the student is dependent on three factors - aptitude, quality of the instructional materials, and his ability to understand the instructional materials. Carroll goes on to explain how these five factors interact to effect student success in school learning. Since Bloom's original paper in 1968 describing mastery learning, a considerable amount Of mastery learning research has been conducted, and the results suggest that the mastery learning model can be easily and inexpensively implemented in courses at any level of education and in a wide range of content areas (Block, 1970). In particular, Block (1971) notes that the best results have been obtained when the course requires either minimal prior learning or previous learning, which all or almost all Of the students possess. In addition, various research findings have shown better results in courses when the content is highly structured and sequential in nature. The outstanding features of mastery learning appear to be that it is easily implementable, does not require the use of a computer to manage instruction, and is appropriate . for almost any content area. Also, if mastery learning is carried out properly, previous research suggests that students will achieve higher scores and have more interest and a better attitude toward school. The curriculum is organized into units of instruction defined by homogeneous clusters of behavioral objectives. Initial instruction on the objectives covered in the unit is group-based. In this respect, mastery I69 learning is structurally different from I PI and Project PLAN. For each unit, one or more criterion-referenced tests, called formative tests, are used to assess mastery of the Objectives. These tests are administered immediately following the completion of the group-based instruction. Individual ization is handled via supplemental materials, feedback, and corrective techniques, applied to students who fail to achieve the defined level of mastery on the test items covering the unit Objectives . Following the last unit of instruction in the course, a final test covering a represent- ative sample of course objectives is administered, and the data used for grading purposes. In describing the mastery learning model, Mayo (1971) notes that: 1. Students are made aware of course and unit expectations, so that they view learning as a cooperative rather unan as a competitive vents re. 2 . Standards of mastery are set in advance for the students, and grading is in terms Of absolute performance rather than relative performance. 3. Short diagnostic tests are used at the end of each instructional unit. 4. Additional learning is prescribed for those who do not demonstrate unit mastery. 5. Additional time for learning is prescribed to students who seem to need it. In summary, it should be noted that many variations on the basic mastery model, as originally proposed by Bloom (1968), are being I70 implemented in schools. For example, different implementers tend to vary in the extent to which feedback/correction procedures are avail able and used (Block, 1971_, Kim, 1971). Block (1971) notes that "To individualize instruction within the context Of ordinary group-based instruction, mastery learning relies heavily on the constant flow Of feedback information to teacher and learner(p.9). " However, it would seem that there is substantially less testing in a mastery learning program than in either IPI or Project PLAN. 171 As compared to IPI, there is no placement testing, and unit pretesting and curriculum-em bedded testing are not emphasized. Unit posttesting and final assessment represent the two major kinds Of testing in the program . In the spirit of Scriven (1967), tests to achieve these two purposes are called "formative" and "summative" tests, respectively. It should be noted, however, that formative tests, or unit posttests as they are called in IPI, are not used for grading . The student data derived from a formative test is used exclusively for diagnosing learning difficulties. A formative test, or alternately called a diagnostic-process test, is a criterion-referenced test that is designed to cover the objectives over a unit of instruction in the mastery learning program . It is used to determine whether or not a student has mastered the material and to serve as a basis for prescribing supplemental work in areas where the student is weak (Airasian, 1971). It is expected also, that the test will reinforce the learning of high-achieving students. Implementers of the mastery learning model have set the passing standard anywhere from 75% to 100%. There is no set number of items or format suggested to measure each Objective; in addition, there is a suggestion that instructional decisions are made on the basis Of responses to individual items . The formative tests in mastery learning represent the key to individualizing instruction since it is on the basis of the scores on these tests that individualization of instruction can take place. Units are kept small so that unit testing takes pl ace frequently in order to increase the effectiveness of the individualization Of instruction component of the program . 172 Although it remains an unresolved problem, the matter of setting mastery levels or cutting scores, by which students can be separated into mastery and non-mastery states on the basis of their performance on test items designed to measure Objectives included in the criterion-referenced tests, has been more actively researched in the context Of the mastery learning program than anywhere. In addition to the usual concern for setting mastery levels high enough to guarantee that students will have sufficient amounts of skill to begin the next segment of instruction, Block (1970) has noted that, in mastery learning, the mastery level is set in a way that will maximize interest in and attitude toward learning. Some interesting controlled research studies have revealed that a mastery level of about 80-85% is substantially better than a level th at is higher or lower. Bl ock's results suggest that setting mastery levels high (95%) may be best for cognitive learning but, in the long run, positive attitudes and interest in the subject are less likely to develop. With a reduction in the mastery level to 85%, there was a reduction in cognitive learning, but selected affective outcomes were maximized . If the mastery level is set lower than 80-85%, students do not usually have sufficient mastery of the skills to proceed effectively with the instruction. The prim ary purpose of the summative test in the mastery learning model is to grade students on the basis of their achievement Of course objectives. The items in the test are keyed to Objectives and are selected to be representative of the total pool of course Objectives . A criterion- referenced interpretation of the scores is recommended. Bloom (1971) 173 prOpOsed that cutting points be located on the ability continuum and that grades be assigned on the basis of a student's position on the continuum and not relative to other students in the course. A norm-referenced interpretation of the scores is also possible (Popham, 1976). A key part of the mastery learning program is the availability of an extensive number of instructional methods for use by students who fail to demonstrate mastery Of the Objectives covered on the formative test. A formative test is administered at the end of the group-based instruction on the unit objectives . Among the alternative resources that are typically avail able to the student are: small-group problem sessions, individual tutoring, and programmed instruction, audiovisual methods, academic games and puzzles, and reteaching. The developers of the program have left the decision on the appropriate instructional correctives to the student. It is expected that, through experimentation with many Of the instructional correct ives, the student will eventually learn which is "best" for him . This would seem to be a very realistic solution to the. problem because of the shortage Of ava'lable data on the apprOpriate matches between student characteristics and instructional correctives. 17h POST TEST ON MASTERY LEARNING By the term "mastery level" we mean A. the learner has perfected a particular task B. the minimum accepted level Of learner achievement C. the maximum measurable achievement level 0 none of the above In a typical mastery based instructional unit, the learner will A. always work by himself and not in a group B. always work in a group C. work in a group or by himself, depending on how the unit is organized In a typical mastery (or competency) based program, the learner A. is given constant feedback in the form of quizzes or questions B. is given a test where the scores indicate his level Of success In mastery learning the resolution of a learning problem by a student usually requires one Of the following measures: A. more time for learning B. different media or materials C. diagnosis to determine what missing prerequisites, knowledge, or skills he must first acquire to master the Objective D. consultation with his teacher E. all of the above 175 Does Carroll's Model Of School Learning (Mastery Learning) deal with matters such as (a) perseverance, (b) aptitude, (c) ability to understand instruction, (d) opportunity to learn?

I77 WE HAVE WAYS FOR YOU TO MASTER Mastery Learning Evidence shows that most instructors begin each new quarter with the expectation that about a third of his students will adequately learn what he has to teach. He expects about a third of his students to fail or to just "get by." Finally, he expects another third to learn a good deal of what he has to teach, but not enough tO be regarded as "good students." This set of expectations, supported by policies and practices in grading, becomes transmitted to the students through the grading proce- dures and through the methods and materials of instruction. The system creates a self-fulfilling prophecy such that the final sorting of students through the grading process becomes approx? imately equivalent to the original expectations (Bloom 1977). 1. Most educational institutions employ grading practices such that inevitably one third of their students will be labeled as a. having failed or learned only enough to just "get by". b. having learned only an average amount of what was taught. c. having learned quite adequately what was taught. d. all Of the above 178 This set of expectations, which fixes the academic goals Of teachers and students is the most wasteful and destructive' aspects of the present educational system. It reduces the aspirations of both teachers and students; it reduces motivation for learning in students; and it systematically destroys the ego and self-concept Of a sizable group of students. Most students (perhaps over 90 percent) can master what we have to teach them, and it is the task of instruction to find the means which will enable our students to master the subject under consideration. Our basic task is to determine what we mean by mastery of the subject and to search for the methods and materials which will enable the largest proportion of our students to attain such mastery. 2. Under Bloom's concept of "Learning for Mastery", with appropriate learning conditions, real mastery of a subject can be achieved by a. at least 90% Of all students b. at least 752 of all students c. at least 652 of all students d. at least 50% Of all students 179 Part of our problems stem from the use of the bell curve for assessment.. We have for so long used the normal curve in grading students that we have come to believe in it. Our achievement measures are designed to detect differences among our learners, even if the differences are trivial in terms of the subject matter. ‘We then distribute our grades in a normal fashion. In any group of students we expect to have some small percent receive A grades. We are surprised when.the percentage differs greatly from about 10 percent. We are also prepared to fail an equal proportion Of students. Quite frequently this failure is determined by the rank order of the students in the group rather than by their failure to grasp the essential ideas Of the course. Thus, we have become accustomed to classify students into about five categories Of level of performance and to assign grades in some relative fashion. It matters not that the failures of one year performed at about the same level as the C students of another year. Nor does it matter that the A students Of one school do about as well as the F students of another school. 3. Using the 'normal' distribution curve as the basis for grading students assures that a. measured differences in achievement among students are important and significant differences. b. failure in a subject area is determined by the failure to grasp the essential ideas of the course. c. both a and b d. neither a nor b 180 Having become "conditioned" to the normal distribution, we set grade policies in these terms and are horrified when some teacher attempts to recommend a very different distribution of grades. Ad- ministrators are constantly on the alert to control teachers who are "too easy" or "tOO hard" in their grading. A teacher whose grade distribution is normal will avoid difficulties with administrators. But even more important, we find ways of convincing students that they can only do C work or D work by our grading system and even by our system of quiz and progress testing. Finally, we proceed in our teaching as though only the minority of our students should be able to learn what we have to teach. 4. Given students 'normally' distributed for aptitude in a subject, and providing all exactly the same learning conditions will result a. in a normal distribution of achievement. b. in a + .70 or higher correlation between achievement and aptitude. c. both a and b d. neither a nor b 181 There is nothing sacred about the normal curve. It is the dis- tribution most appropriate to chance and random activity. Education is a purposeful activity and we seek to have the students learn what we have to teach. If we are effective in Our instruction, the distri- bution of achievement should be very different from the normal curve. In fact, we may even insist that our educational efforts have been unsuccessful to the extent to which our distribution of achievement approximates the normal distribution. Individual differences in learners is a fact that can be demon- strated in many ways. That our students vary in many ways can never be forgotten. That these variations must be reflected in learning stand- ards and achievement criteria is more a reflection Of our policies and practices rather than the necessities Of the case. Our basic task in education is to find strategies which will take individual differences into consideration but which will dO so in such a way as to promote the fullest development of the individual. .A learning strategy for mastery may be derived from the work Of Carroll (1963), supported by the ideas of Morrison (1926), Bruner (1966), Skinner (1954), Suppes (1966), Goodlad and Anderson (1959), and Glaser (1968). In presenting these ideas we will refer to some Of the research findings which bear on them. 182 Put in its most brief form the model proposed by Carroll (1963) makes it clear that if the students are normally distributed with respect to aptitude for some subject.(mathematics, science, literature, history, etc.) and all the students are provided with exactly the gag; instruction (same in terms Of amount of instruction,.quality of in- struction, and time available for learning), the end result will be a normal distribution on an appropriate measure of achievement. Further- more, the relationship between aptitude and achievement will be re- latively high (correlations of + .70 or higher are to be expected if the aptitude and achievement measures are valid and reliable). Con- versely, if the students are normally distributed with respect to aptitude, but the kind and quality Of instruction and the amount of time available for learning are made appropriate to the characteristics and needs Of gash student, the majority of students may be expected to achieve mastery of the subject. And, the relationship between aptitude and achievement should approach zero. 5. Given students 'normally' distributed for aptitude in a subject and providing learning;conditions appropriate to the needs of each individual student will result in a. the majority of the students achieving mastery in the subject. b. a correlation between achievement and aptitude approaching zero. c. both a and b d. neither a nor b 183 We have come to recognize that individuals do differ in their aptitudes for particular kinds of learning and over the years we have developed a large number of aptitude tests to measure these differ- ences. In study after study we have found that aptitude tests are relatively good predictors of achievement criteria (achievement tests or teacher judgments). Thus, a good set of mathematic aptitude tests given at the beginning of the year will correlate as high as + .70 with the mathematics achievement tests given at the end Of the course in algebra, or some other mathematics subject. The use of aptitude tests for predictive purposes and the high correlations between such tests and achievement criteria have led many Of us to the view that high levels of achievement are possible only for the most able students. From this, it is an easy step to some nOtion of a causal connection between aptitude and.achievement. The simplest notion of causality is that the students with high levels of aptitude can learn the complex ideas of the subject while the students with low levels of aptitude can learn only the simplest ideas of the subject. 6. The high correlation usually found between aptitude tests and achievement tests indicate that a. high achievement is possible only for the high aptitude students. b. students with low aptitude can learn only the simplest ideas. c. both a and b d. neither a nor b 18h Carrol.sees aptitude as the amount Of time required by the learner to attain mastery of a learning task. Implicit in this formulation is the assumption that, given enough time, all students can conceivably attain mastery of a learning task. If Carroll is right, then learning mastery is theoretically available to all, if we can find the means for helping each student. One type of support for this view is to be found in the grade norms for many standardized achievement tests. These norms demonstrate that selected criterion scores achieved by the top students at one grade level are achieved by the majority of students at a later grade level. Further support is available in studies where students can learn at their own rate. These studies show that although most student eventually reach mastery on.each learning task, some students achieve mastery much sooner than dO other others (Glaser, 1968; Atkinson, 1967). Can all students learn a subject equally well? That is, can all students master a learning task at a high level of complexity? As we study aptitude distributions in relation to student performance we have become convinced that there are differences between the extreme students and the remainder of the population. At the top Of the aptitude dis- tribution (1 percent to 5 percent) there are likely to be some students who have a special talent for the subject. Such students are able to learn and to use the subject with greater fluency than other students. The student with special aptitudes for music or foreign languages can learn these subjects in ways not available to most other students. 185 Whether this is a matter of native endowment or the effect of previous training is not clear, although this must vary from subject to subject. We believe (as does Carroll) that aptitudes are predictive of rate of learning rather than the level (or complexity) of learning that is possible. Thus,‘we are expressing the view that, given sufficient time (and appropriate types of help), 95 percent of students (the top 5 percent + the next 90 percent) can learn a subject up to a high level of mastery. We are convinced that.the grade of A as an index of mastery of a subject can, under appropriate conditions, be achieved by up to 95 percent of the students in a class. It is assumed that it will take some students more effort, time and help to achieve this level than it will other students. For some students the effort and help required may make it prohibitive. Thus, to learn high school algebra to a point of mastery may require several years for some students but only a fraction of a year for other students. 7. The fact that, on standardized achievanent tests, the top scores achieved by only a few students at one grade level are achieved by the majority at a later grade level, supports the view that a. aptitude is the amount of time required to attain mastery of a learning task. b. given enough time, the majority of students can achieve mastery of a learning task. c. both a and b d. neither a nor b 186 Whether mastery learning is worth this great effort for the students who may take several years is highly questionable. One basic problem for a mastery learning strategy is to find ways of reducing the amount of time required for the slower students to a point where it is no longer a prohibitively long and difficult task for these less able students. We do not believe that aptitude for particular learning tasks is completely stable. There is evidence (Bloom, 1964; Hunt, 1961) that the aptitude for particular learning tasks may be modified by appro- priate environmental conditions or learning experiences in the school and the home. The major task of educational programs concerned with learning to learn and general education should be to produce positive changes in the students' basic aptitudes. It is likely that these aptitudes can be most markedly affected during the early years in the home and during the elementary years of school. Undoubtedly, however, some changes can take place at later points in the individual's career. However, even if marked changes are not made in the individual's aptitudes, it is highly probable that more effective learning conditions can reduce the amount of time required to learn a subject to mastery for all students and especially for the students with lower aptitudes. It is this problem which must be directly attacked by strategies for ‘mastery learning. 187 8. Which of these statements is a mistaken assumption? Aptitudes are predictive of rate of learning rather than level of learning. Aptitudes for particular learning tasks are stable and cannot be modified by the environment or learning ex- periences. There are real differences in aptitudes for particular learning tasks at the extremes of the student population. Each individual student can vary considerably in his aptitudes for different learning tasks and subject areas 0 188 One may start with the assumption that individual students need very different types and qualities of instruction to achieve mastery. That is, the same content and objectives of instruction may be learned by different students as the result of very different types of instruction. Carroll (1963) defines the "quality of instruction in terms of the degree to which the presentation, explanation, and ordering of elements of the task to be learned approach the optimum for a given learner." Much research is needed to determine how individual differences in learners can be related to variations in the quality of instruction. There is evidence that some students can learn quite well through independent learning efforts while others need highly structured teach- ing-learning stiuations (Congreve, 1965). It seems reasonable to expect that some students will need more concrete illustrations and explanations than will others; some students may need more examples to get an idea than do others; some students may need more approval and reinforcement than others; and some students may even need to have several repetitions of the explanation while others may be able to get it the first time. 9. One of the more pressing requirements of instructional research today is a. to find the one method, material, and curriculum that is best for all students. b. to define the qualities and kinds of instruction needed by various types of learners. . c. both a and b d. neither a nor b p 189 ‘If the student has difficulty in understanding the teacher's instruction and/or the instructional material, he is likely to have great difficulty in learning the subject. The ability to understand instruction may be defined as the ability of the learner to understand the nature of the task he is to learn and the procedures he is to follow in the learning of the task. Here is a point at which the student's abilities interact with the instructional materials and the instructor's abilities in teaching. For the student in our highly verbal schools it is likely that this ability to understand instruction is primarily determined by verbal ability and reading comprehension. These two measures of language ability are significantly related to achievement in the majority of subjects and they are highly related (+ .50 to + .60) to grade point averages at the high school or college level. What this suggests is that verbal ability (independent of specific aptitudes for each sub- ject) determines some general ability to learn from teachers and in- structional materials. 10. Giving students a choice of alternative instructional methods and materials a. probably will have the greatest payoff in the ability of students to understand instruction. b. should help students to become more independent and to overcome feelings of defeatism and passivity about learning. c. both a and b d. neither a nor b 190 Carroll defines perseverance as the time the learner is willing to spend in learning. If a student needs to spend a certain amount of time to master a particular task, and he spends less than this amount in active learning, he is not likely to learn the task to the level of mastery. Carroll attempts to differentiate between spending time on learning and the amount of time the student is actively engaged in learning. - In our own research we are finding that the demands for per- serverance may be sharply reduced if students are provided with in- structional resources most.appropriate for them. Frequent feedback accompanied by Specific help in instruction and material as needed can reduce the time (and perseverance) required. Improvement in the quality of instruction (or explanations and illustrations) may reduce the amount of perseverance necessary for a given learning task. There seems to be little reason to make learning so difficult that only a small proportion of the students can persevere to mastery. Endurance and unusual perseverance may be appropriate for long-distance running -- they are not great virtues in their own right. The emphasis should be on learning, not on vague ideas of discipline and endurance. ll. Perseverance at a particular learning task will probably decrease a. 'with frequent positive feedback on progress. b. with frequent reward for correct performance. c. 'with evidence of coming success at the task. d. with repeated failure to achieve mastery of the task. 191 OPERATING PROCEDURES The operating procedures we have used are intended to provide detailed feedback to teachers and students and to provide specific supplementary instructional resources as needed.' These procedures are devised to insure mastery of each learning unit in such a way as to reduce the time required while directly affecting both quality of instruction and the ability of the student to understand the instruc- tiOn. Formative Evaluation. One useful operating procedure is to break a course or subject into smaller units of learning. Such a learning unit may correspond to a chapter in a textbook, a well-defined content portion of a course or a particular time unit of the course. We have tended to think of units as involving a week or two of learning activity. Using some of the ideas of Gagne (1965) and Bloom (1956) we have attempted to analyze each unit into a number of elements ranging from specific terms or facts, more complex and abstract ideas such as concepts and principles, and relatively complex processes such as application of principles and analysis of complex theoretical statements. We believe, as does Gagne (1965) that these elements form a hierarchy of learning tasks. -192 We have then attempted to construct brief diagnostic-progress tests which can be used to determine whether or not the student has mastered the unit and what, if anything, the student must still do to - master it. We have borrowed the term "Formative Evaluation" from Scriven (1967) to refer to these diagnostic-progress tests. Frequent formative evaluation tests pace the learning of students at the appropriate time. The appropriate use Of these tests helps to insure that each set of learning tasks is thoroughly mastered before subsequent learning tasks are started. 12. Formative evaluation tests a. are essentially diagnostic, self-study guides and, thus, a part of the learning process. b. are usually given at least six weeks apart to provide general review. c. are essentially comprehensive achievement tests. d. none of the above. 193 Each formative test is administered after the completion of the apprOpriate learning unit. While the frequency of these progress tests may vary throughout the course, it is likely that some portions of.the course —- especially the early sections of the course - may need more frequent formative tests than later portions. Where some of the learning units are basic and prerequisite for other units of the course, the tests should be frequent enough to insure thorough mastery of such learning material. For those students who have thoroughly mastered the unit, the formative tests should reinforce the learning and assure the student that his present mode of learning and approach to study is adequate. Since he will have a number of such tests, the student who consistently demonstrates mastery should be able to reduce his anxiety about his course achievement. For students who lack mastery of a particular unit, the formative tests should reveal the particular points of difficulty - the specific questions they answer incorrectly and the particular ideas, skills, and processes they still need to work on. It is most helpful when the diagnosis shows the elements in a learning hierarchy that the student still needs to learn. We have found that students respond best to the diagnostic results when they are referred to particular instructional materials or processes intended to help them correct their difficulties. The diagnosis should be accompanied by a very specific prescription if the students are to do anything about it. 13. 199 Which statement is correct? a. Students respond best to the diagnostic results of a formative test when they are given a general remedial prescription rather than a specific prescription. For students who fail to master a particular unit of material, the formative test should reinforce the learning and assure the student that his present mode of learning and approach to study is adequate. both a and b d. neither a nor b 195 These formative tests may also provide feedback for the teacher since they can be used to identify particular points in the instruction that are in need of modification. The formative evaluation tests also can serve as a means of quality control in future cycles of the course. The performance of the students on each test may be compared with the norms for previous years to insure that students are doing as well or better. Such comparisons can also be used to insure that changes in instruction or materials are not producing more error and difficulty than was true in a previous cycle of the course. 14. Which statement is incorrect? Formative evaluation tests la. should provide detailed feedback to the teacher on the particular points of instruction that need modification. b. should be graded to maintain high student motivation and to determine student capabilities. O. can serve as a means of quality control in future cycles of a course. d. provide detailed diagnosis and prescription of what is yet to be done before mastery is complete.
