Longitudinal growth data on this child were obtained from the Child Development Laboratory of the Bureau of Research and Services of the College of Education at Michigan State University. The data covered the following four areas: [1] Physical Development, [2] Mental Development, [3] Subject- Matter Achievement, and [4] Personality, Aptitudes, and Abilities. These data, collected over a period of twelve years by the laboratory personnel, included actual measure— ments of height and weight at frequent intervals, mental ability tests, personality and interest inventories, periodic anecdotal records of the individual's behavior throughout the 2 study, information from the school records, and interviews with the boy's teachers and parents. The Olson and Courtis techniques of interpretation of growth data were used to discover the individual's patterns of growth and'the interrelationships which existed among them. From the analysis and interpretation of these data it was concluded that the school did not provide the type of learning eXperiences for the child which were consistent with child growth and develOpment principles. It was assumed that if the learning eXperiences planned for the individual had been geared more nearly to his needs, interests, and abilities positive changes might have been affected in his academic achievement, as well as in his personal-social relations and his attitudes, habits, and emotional adjustments. Implications were drawn from this longitudinal case inventory for individualizing the program of instruction for the boy under study. An attempt was also made to show how like data for children could contribute to the individualization of the curriculum for each child in a group. Suggestions were made in the areas of evaluation and testing, meeting individ- ual interests and needs, personal-social relationships, motivation for learning, and effective home-school relations. This study was meant to be illustrative of how individ- ual methods could be used to adapt the curriculum to the learner.

Since the broad aim of education is to improve the quality of living in the school, the family, and the community, the kind of program that exists, the variety of experiences that are provided and the wide use of materials and resources that are available, are very important. Up until recently, educators have conceived improvement as a matter of manipulating these exterior factors on the assumption that content, methods, and materials are the crucial aspects of learning. With the ever increasing research on the individ- ual and how he grows and learns this concept has been modified. More and more research has demonstrated that there is no magic formula which will apply to all human beings everywhere. In spite of the use of the best known techniques, the ever increasing acquisition of knowledge, and the almost limitless resources and materials, a corresponding degree of success on the part of the learners has not been achieved. Learning takes place within the individual. It is dependent upon what he brings to the situation: his attitude, habits, feelings, abilities, past experiences, interests, 2 needs, and a host of other conditioning factors.1 These can not so easily be controlled. Within any group the range is great and the multiplicity of the combinations of determinants and their complexity approach infinity.2 Although the physical environment for two individuals may be ostensibly the same, each individual perceives this environment differently. If it is assumed that the individual is himself part of his environment then he becomes an impor- tant factor in the learning situation. For the purposes of this study Denton is the case in point. An attempt has been made to find out as much as possible about this individual, not Just for the knowledge, not Just to try to understand the boy, but most important to discover ways in which this knowledge may be used to enrich the environment for learning and to “tailor-make” the program so that comparable individuals may benefit most from the expe- riences which are provided for them and which they provide for themselves. Any curriculum to be most effective must be so determined. Admittedly, no generalization can be made on the basis of this one case. Furthermore, the writer on the basis of 1Arthur I. Gates, §£,gl., Educational ngcholo x (New York: Macmillan, 1942), Chapter IX. 2Association for Supervision and Curriculum Deve10pment, Guidance in the Curriculum, 1955 Yearbook (Washington, D. 0.: National Education Association, 1955). pp. 50-51. 3 this one detailed study, does not intend to suggest an answer to all the educational problems. What is intended is to analyze these data and indicate a process or manner of approach to some of the problems which exist and project some possible ways for arriving at better solutions to these problems. Neither is it assumed that the curriculum should be built for one child, but rather that each child should be considered carefully if Optimum learning for all is to be the goal. Formal education in our society is a group process, and the interaction among this group is vital to the ultimate ends of education. Although this is not an attempt at curriculum con- struction it implies a curriculum sufficiently flexible to be adaptable to each child. It must be remembered that even though individuals within a group have many differences, at the same time there exist certain common elements. For example, there is a wide range of abilithes, but within this range there are many likenesses; interests differ but there are those common to some in the group and often to many or most of the individuals; needs vary but some are basic to all. It should be repeated that it is not being inferred that a teacher with thirty pupils should build thirty curricula, one for each child, but that the curriculum be so enriched that each is able to find himself within it-«meet his needs, follow his interests, and approach more nearly his potential. )4 The implications for educational practice included in this study are not limited solely to data of this individual study. These findings serve as a basis for discussion and as an example from which to project the thesis but are tempered necessarily by the present day literature in the field, and the writer's experiences, observations, and philosophy of education. The purpose of this study, then, may be summarized as follows: 1. To summarize the multiple growth data collected on one child over a period of time. 2. To point up by graphic and longitudinal methods inter-relationships which exist among the different aspects of growth and development in the case of Denton. 3. To relate the longitudinal study of Denton to the established norms and to discover if possible his individual growth patterns. A. To draw implications from this study for educational practices, and to demonstrate how data on individual children may be helpful in planning programs of instruction which would more realistically meet the individual needs of children. 5. To suggest the kinds of data which are most helpful in interpreting growth. Chapter II deals with the general develOpmental character— istics of Denton with reference to the established norms. The 5 following categories have been arbitrarily selected to allow for a more workable organization: [1] Physical grOWth and health status, [2] Mental Development, [3] Academic learnings, [A] Personal and social development, [5] Home and family environment, and [6] General school environment. Chapter III attempts to show inter—relationships which exist among the various aspects of Denton's growth. There are presented graphically by means of both the Olson concept of organismic age and the Courtis theory of cyclical growth. Some attempt has been made to reconcile where possible this case with the above hypotheses and to indicate patterns and rate of growth as well as to predict future growth and possible maxima. Chapter IV is a consideration of implications of this study for improvement of classroom practices. This includes suggestions to teachers to help the child set realistic goals which are consistent with his potential, his rate and pattern of growth, as well as his needs and interests. There is no deliberate attempt on the part of the writer totbe unduly critical of present practices although many of the statements which appear in this chapter may necessarily appear to be. The emphasis is entirely upon change for better’educational experiences for all children. 6 The Data and How They Were Gathered Denton is one of a study of seventy individual children which was begun on a COOperative basis by the Everett Elemen- tary School and the Child Development Laboratory of the Bureau of Research and Services, College of Education, Michigan State University. This school was selected because of its proximity to the university and for the reason that the students, the curricular content, and the teaching methods were considered typical for the State of Michigan. The formal study was begun in the fall of 19A} when this group of boys and girls entered kindergarten. It was carried on in detail through the sixth grade of the elementary school. The data for grades seven through eleven have been collected somewhat informally since the studies were not continued in detail through these years.3 The following are described as the major purposes. 1. Research to determine the relationship of the child's growth and development to the school program. 2. ObserVation.of children as a part of a program for training teachers to understand better the principles of child growth and development. 3Some of these children continued their schooling in the Everett high school. Twenty-two of them have at the time of this study completed the eleventh grade. The staff of the Child DevelOpment Laboratory and graduate students have col- lected the information from records and interviews for the secondary school years. 7 3. Service to the school and thus the child involved in the program. The studies have been carefully supervised by the Child Development Staff of the University. The observations were done by students being trained in these techniques. The testing was done by graduate students and laboratory staff members. The research aspect of the study involved the recording, processing, and interpreting of tests and measurements of the twenty-two individuals for a period of twelve years. The tests and measurements recorded by a trained graduate student or a staff member covered four areas: [1] Physical.Development, [2] Mental Development, [3] Subject-Matter Achievement, and [h] Personality, Aptitudes, and Abilities. Physical Development. Height and weight were recorded regularly from the first month of kindergarten in l9b3 through the last month of the sixth grade in 1950. Two measurements were recorded in the eighth grade and one in the tenth. Height and weight at birth plus early dentition and early physical developmental tasks were recorded from the family's and doctor's records. “It is obvious that the validity of these data can be questioned, but must be accepted as the most valid data obtainable. 8 Mental Development. The Kuhlman-Anderson test Was administered in the first, second, fourth (twice), fifth, sixth, and eighth grades. It was processed in terms of mental age, grade age, and I. Q. An individual test, the Stanford-Binet, was administered in the seventh grade. Subject-Matter Achievement. The Stanford Achievement test was administered regularly through the elementary school. Some other measures of achievement were also used. Samples of work, teacher progress reports, and semester ratings may be found in the individual's record file. Personality, Aptitudes, and Agilities. The Millard Personality Inventory was recorded by the teacher each year from second through sixth grade. The Rorschach test, the Thurstone Temperament Schedule, the Mooney Problem Check List, the Differential Aptitude Tests, and the Kuder Preference test were administered at the high school level. In addition to the above, the following are included in each child's file: 1. A yearly case inventory including information relating to the following six areas: A. General School Background . Physical Growth and Health . Mental Development B C D. Academic Learnings E. Personal and Social Deve10pment F . Home and Family Environment 9 2. Periodic anecdotal records of the individual's behavior throughout the study. 3. Samples of the individual's work. h. Photographs. 5. Recordings of unstructured interviews. 6. Information from the school records, including health and attendance records. 7. Interpretations of the growth data both in terms of organismic age as reported by Olson, and the law of growth as reported by Courtis. The Multiple Approach 3g Child Study In the case of Denton an attempt has been made to gather data about many factors which are significant to the very complex processes of growing and learning. It is not implied that these factors are separate and distinct. The human organism does not grow and develop in a compartmental- ized way. The child grows as a whole. In order to try to arrive at some degree of understanding about grthh, some of these factors which can be observed and measured are sorted out for study. Many others might have been selected. An attempt is made to find out some things about how eachflaspect of growth relates to total growth, and to see if there is a togetherness of growth as it proceeds toward maturity. SStuart A. Courtis, "Maturation Units for Measurement of Growth,'.§ghogl and Society, Vol. xxx (November 16, 1929). 10 It is not the purpose here to prove the relationship of these aspects, but to use the available data to show whether or not Denton conforms to this concept. » The longitudinal study of an individual might be con- cerned with the measurement of one aspect of growth over a period of time. The multiple approach, however, in this case has been used. Data have been collected and recorded about many factors contributing to Denton's physical growth and his increase in skill and complexity of function. The Longitudinal and Crossegectional flgthggg The testing programs which have grown so extensively in the past three or four decades have furnished those who are working in the field of education with worlds of data about people from which valid generalizations can be made. For example, in the areas of mental ability or I.Q., reading and other academic achievements, physical grOWth, the develOp— ment of motor skills, etc., data are available from which normal curves can be constructed and against which individuals and special groups can be measured. This method, however, can and often does work a hardship upon an individual since it ignores his uniQueness and does not take into account the wide range which necessarily exists within the data to contribute to its oversimplified conclusions. Misuse of the results of these cross-sectional studies has tended to cause confusion among such designations as "average," ”normal," "exceptional,“ and “sub~normal,! 11 It has given credence to such misconceptions as "the five-year-old child," ”third—grade reading," or "sixth grade spelling." Instead of being conceived as reference points‘ or norms they too often have become in practice to be used as goals or standards, and have become expectations for all children. The present movement toward wider use of the longitud- inal method of study of the multiple aspects of the growth and development of individuals does not ignore nor minimize the importance of the cross-sectional approach. The longitudinal method in dealing with individual growth patterns helps those who work with boys and girls to understand them in terms of their own abilities, skills, interests, and developments rather than measuring them only against the cross-sectional sampling. There is, of course, some use of the norms, but they are not being used as a standard for all. EXpectation and prediction become individ- ualized rather than being based alone upon generalized measure- ments which are not so effective when applied to specific entities. According to Olson: The cross-sectional method is economical and rapid, and it is possible to get data that can be summarized in a brief period of time. The longitudinal method is expensive and slow, and it takes many years to accumulate data that will help trace the course of deve10pment of individual children. The cross- sectional method was very effective in showing the individual differences that exist among children 12 with respect to any trait at any given age. It tells little, however, about the individuality of growth or change with time. The cross-sectional method tends to minimize and conceal by an averaging— out process the changes which may actually be very dramatic . . . . There is no real antagonism between longitudinal and cross-sectional methods. Both are useful and supplement one another; both have advantages and limitations. A thorough knowledge6of both methods permits more penetrating analyses. Teachers generally are seeking more and more information about the boys and girls with whom they are dealing. They are no longer satisfied with only the objective test results, but are becoming increasingly aware of the importance of such factors as the family relations, cultural background, inter- personal relations, attitudes, and values of the individual. The techniques for gathering data such as illustrated in this case of Denton are being used more commonly by teachers as they feel the need for individualizing the program of instruction. The professional teacher is no longer content with the traditional approach which offers the same diet for all appetites even though they differ widely both in degree and kind. When dealing with growth on a longitudinal basis, there are certain parameters which need to be used and described; namely, starting-point, rate, maxima. and growth pattern. '1 6Willard 0. Olson, Chi;g DevelOpment (Boston: C. D. Heath, 1949). pp. lu-15. 13 Significance g; Starting-Point Actual starting point or incipiency is somewhat difficult to determine. For purposes of physical measurements the starting point is coincidental with conception. There are those also who hold that certain predispositions are formed prenatally from the mother's attitudes about pregnancy, her acceptance of the situation and her calmness, serenity or anxieties and fears. No one is able to discover exactly the incipiency for the various developmental tasks.7 The point at which a child takes his first steps might be considered the incipiency for walking; when he says his first word, for talking; or when he reaches a certain score on a reading test, for reading. Olson and Hughes in their longitudinal studies of reading achievement have for their purposes arbitrarily adjudged a child to have learned to read when he has achieved a reading age of eighty-fourmonths on the Gates Primary Reading Test. For their studies this then becomes the incip- iency or starting-point of the growth curve. The dictionary defines incipiency as “very beginning, early stage." As it relates to the Courtis technique it assumes that the child emerges into a given cycle with certain 7Incipiency for many aspects of growth and development could very logically be traced back to conception, and for others, to birth. lu grthh already manifested. It accounts for growth already made and provides a starting point for such growth under consideration in a Specific cycle. Equivalent Growth Age A B C Chronological Age in Months Fig. 1. Comparative Growth Curves To illustrate the importance of the starting-point and its relationship to the grOWth pattern, the three hypothetical graphic illustrations shoWn above may be used. In these figures z represents the norm or average while x and y represent individual cases. In Figure 1-A, x and y have different starting-points but approximately the same rate of growth. In Figure l-B, x and y have approximately the same starting-point but different rates. In Figure 1-C, x and y have different starting-points, approximately the same rate, but different maxima. 15 In Figure 1-A, x would be considered by many as a faster grower than y since his level of achievement is higher. On the basis of achievement alone, a teacher may be misled without the additional information regarding incipiency and rate of growth. The tendency is to treat x as though he were achieving more than y when in reality they are achieving identically in terms of amount; x is an early starter; y is a late starter. With the portion of the data shown here it is not possible to determine differences in maxima. These illus- trations of comparative growth curves are not unusual examples of actual cases. Starting—point by itself is no measure of future grOWth. When a child begins walking, talking, cutting teeth, or reading. is not a valid basis on which to predict either rate or maxi— mum of growth. It is also important to note that all the cases shown in these examples may be growing towards maturity at their own individual rates, and, were this true, would be said to be equally successful in the specific area of growth being considered. Significance 2; Rate As has been shown in the discussion of starting-point, rate is an important aspect in the longitudinal study of growth and deveIOpment. According to OlsonB, ”Rate refers to the amount of increment or increase in a structure or 8Olson,.9_p_. cit., p. h. I 16 function in terms of units of time." Since this rate does vary greatly from child to child, it becomes mandatory for those dealing with children in the learning situation to have this knowledge about each child in order that the expectations which he sets for himself or are set for him, have realistic value. In order to establish rate, measurements in the areas involved must be made periodically over a significant length of time. Height is a physical measure of growthivhich is least likely to be affected environmentally. In using this measure-' ment as a norm there is assumed to be a consistency of other aspects of growth and deve10pment with physical growth. The Courtis Technique, which interprets growth in generalized units of per cents of maxima, is not dependent upon actual magnitude of achievement. The judgments which are made in terms of correlations are on this basis. For example, an individual may be reaching his height maximum [100 per cent] at a chronological age of 195 months, and at the same time approaching mental maturity with a mental age of 250 months. He may be short or tall, but percentage wise these two growth curves would be coincidental at this point. In other words, he grew at constant rates in both aspects of growth toward dif- ferent maxima, both of which may be represented by 100 per cent. 17 Individual Patterns 2; Growth With the longitudinal approach, as more and more data are collected over a period of time and when these data are summarized graphically or organized systematiCally in other ways, certain trends of development begin to emerge. Certain regular progressions of change become apparent. These are referred to as patterns of growth. In cross-sectional studies patterns are determined for the sampling and these patterns are called the norms. When plotted as curves, these are called "normal curves.” In some of the graphs used in this study the individual's grOWth curves are compared with the norm or average-~the pattern of grOWth representing the total population. From these norms it has been established that all children progress through the same growth sequences. The average pattern, hoWever, does not represent for the individual ”normal develOpment.F According to Jenkins, Shacter, and Bauer: A specific statement of what is "normal development" at a particular age level is a dependable statement only as it is correctly interpreted with understanding that (1) individual children vary, each being like only himself; (2) "normal“ means not a point on a scale, but a range, extendin over a relatively wide portion of a measure; and (3 “deveIOpment“ refers not to physical growth alone, but to mental, social, and emotional growth as well. 9Gladys Gardner Jenkins, Helen Shacter, and William Bauer, These Are Your Children (Chicago: Scott, Foresman and Company, 19537. p. 2 . 18 In this longitudinal study an attempt has been made to discover the existing patterns of the physical growth and the development in such areas as mental ability, social respon— sibility, emotional adjustment, academic achievement, and family relationships, as well as the interrelations amongthem. Patterns in some of these areas [e.g., physical growth and academic achievement] lend themselves to more or lessOEUective measurement and can be demonstrated graphically. Patterns of deve10pment in other areas such as those which deal with the social and emotional are much more subjectively determined not through exact measurement but by the use of descriptive data collected by means of observational and interviewing tech— niques. The techniques used in observation and interview, the degree of skill of the persons gathering and recording the data, and the interpretation placed upon the data by the sum- marizer determine the validity of the data. As more data are collected and recorded by carefully supervised students andtw' trained staff members over a long period of time, individual biases and inaccuracies tend to be minimized. The individual pattern of development thus is not influenced by any single observation, test, or judgment. The more accurately descriptive and anecdotal material is the less susceptibleit is to misrep- resentation and misinterpretation. Although anecdotal tech- niques are admittedly subjective and open to question because of the human factor,they do furnish evidence whichhasa certain l9 validity in the case study approach in a variety of fields of endeavor, e.g., medicine, social work, psychology, sociology, and anthropology, as well as child growth and development. In establishing patterns of growth physical measurements, although subject to certain inaccuracies, are probably the most reliable measurements. There are certain intangibles occurring in the growth patterns which are used for interpre- tation. For example, When health factors intervene to arrest physical growth, certain behavioral changes may seem to occur. Description of behavior which is significant in the judgment of the professional observer may give understanding and insight into concomitant variations in the growth patterns. This does not necessarily assume a cause and effect relationship nor that the changes arise from a common cause. Normal Growth 9; the Individual When cross-sectional data are used, the term normal refers to a certain percentage Which falls within a determined range above and below the mean or>average. An individual who falls within this range whether it be in mental ability, achievement in certain skills or abilities, or growth in height or weight, is often described as normal or achieving or growing normally. It must be noted, however, that this evaluation is always in terms of the total sample. If each child grows and learns according to a discoverable rate, and in relationship to his individual starting-point,the judgment 20 as to his success cannot be made on the basis of group established criteria. Being up to norm or below or above norm would not be indicative of success if the individual's ' rate of growthlae either unknown or not considered. What is being implied here is that norms can be estab- lished for each individual when enough longitudinal data are available to establish his patterns of grOWth. From these patterns it may well be determined that some of those who are above norm are retarded or not growing successfully according to their pattern. Contrariwise it will most certainly be found that many who are below the so-called norm seem to be growing and learning successfully according to their own rates. Much more accurate evaluation of present growth and prediction of future growth becomes possible on the basis of these kinds of data. Normal growth is what is normal for the individual—- abnormal refers to that which is inconsistent with his individ- ual rate and pattern of grOWth. Many of the implications this concept has for educational practices become quite obvious. Millard sums it up in this way: When single measurements of growth and achievement are the only data available for study, it is easy for teachers to fall into the error of considering one child as superior or inferior to another. Data from a single measurement are virtually useless in making reliable interpretations. Two girls with different reading scores may be used to illustrate the point that growth is a very complex process and does not lend itself to easy interpretations. Case histories indicated that Girl 3 21 received "F's" in reading in both the first and second grades. In grade three she was given "C's," in grades four and five her marks were "B's" and finally in grade six ”A's.” Girl A's marks followed a reverse pattern. In terms of growth, each girl was found to be following a rather precise sequence. This would indicate consistent growth throughout all grades. There was no change in the curves that would justify shifting evaluations. The marks given by the teachers had no correct interpretative values regarding the growth of either. The facts are that Girl A started her reading curve sufficiently early to seem superior, whereas Girl B started so late as to be considered dull. In regard to the maximum or real reading poten— tiality, Girl B was definitely superior, but for three years this potentiality was unrecognized.

Maternity and Infancy Denton was born in a hospital with a doctor in attendance on September 29, 1938. This was the mother's third pregnancy. She visited the obstetrician regularly every month during this time. Her pregnancy was normal except for a urinary disturb— ance two weeks before the delivery. She was in labor forty- eight hours before the birth as compared to thirteen hours for the first child and seven hours for the second. The labor was described as spastic. Some gas was used as anesthetic. The birth was listed as two weeks premature although Denton's weight [eight pounds, two ounces] would indicate a term birth. He was nineteen inches long at birth. By the end of the first month he weighed ten pounds, one ounce. The mother had breast fed the first two children, but claimed to have broken out with hives when she started nursing Denton. He was put on a formula at the beginning of the second month. The formula prescribed by the doctor was of low grade milk until the age of four months to control his weight. 22 23 He was a good sleeper, sleeping twenty hours to the third month, eighteen to the sixth, sixteen to the twelfth, and twelve hours from the twenty-eighth to the thirty-sixth month. Denton's mother reports that he was trained for the. toilet at two years. She started using rectal suppositories. twice daily when he was two weeks old and "never had a soiled diaper.” He was, however, a bed wetter until the age of sight when his father “gave him a good Spanking and he never wet the bed again.” The developmental tasks which were accomplished at indicated ages are shown in Table I. The ages of accomplishment compare quite favorably with the scales of Spock, Gesell, Watson and the publication of the Children's Bureau. In fact Denton's performance in each case cited represents the early end of the range given by these authorities as the norms. Although his birth was recorded as premature his early rate of grOWth was accelerated. He increased in weight to the extent that dietary measures were found necessary at the beginning of the second month. 24 TABLE I DENTON'S ACCOMPLISHMENT OF VARIOUS DEVELOPMENTAL TASKS AS COMPARED WITH NORMS ESTABLISHED BY SELECTED AUTHORITIES W Age Developmental Accomplishid Age Considered as Norm by Authority Task by Denton Spockz Gesellj— Watson“ C.B.P.5 Discovering 2-3 hands 3 months months 12 wks Discovering feet h months Sitting with Support 5 months 16 wks Sitting with- 7-9 7 6-8 out Support 6 months months 36 wks months months 7-1/2 6-12 8 7-9 Crawling months months no wks months months Standing with 8-12 9-12 Support 7 months months months Walking 12-15 15 lu—IS Alone 12 months months months months Cutting com- lsthalf plete set of of third 20-30 30 milk teeth 2h months year months months 1Doctor's and Family's Records. 2Benjamin S ock, Baby and Child Care (New York: Pocket 3Arnold Gesell and Frances Ilg, Child Development (New York: Harpers, 1949), passim. “Ernest H.

General Health Factors Denton was rated by the teachers from grades one through six on the Millard Revision 9; the McFarlane Adjustment Inventory. In the area of Physical Efficiengy_and Health ‘gggggg there appears to be nothing unusual that would affect Denton's school experiences or activities. He is described as rather small-boned and of average build. He had the three- day measles at the age of four, chicken pox at age seven, rinngrm in the third grade, and tonsillitis in the second and third grade. On the various items of the inventory he is consistently rated ”normal," "good," "regular,” "sufficient," etc.,-~at the positive end of the continuum in all the factors of general health. The third gradeiieacher wrote, "Denton doesn't seem sickly in any way, but perfectly healthy and normal." The fourth grade teacher commented, ". . . average in height, weight, and health." At no time. according to this inventory is there any mention of special physical defects or difficulties. It is questionable as to just how much credence can be placed upon the teacher ratings. There is a possibility that in rating children by observation alone the tendency of the teacher might be to select the mid-point of the continuum unless there exists some defect too obvious to be overlooked. Since, however, he was rated in detail on the inventory during each 26 of the school years and the records show nothing abnormal nor indicate any general health problems, it may be assumed that Denton's physical characteristics and abilities were at least average and certainly satisfactory to his adjustment. It is also important to note that on the Mooney Problem Check List, Denton showed no particular concern about his personal health other than underlining item No. 114 "Frequent Colds.“ Figure 2 represents the Olson graph of Denton's height and weight in comparison with the norm for boys. It shows that Denton was above the average in weight throughout and with the exception of a short period around the age of seven, he was also above average in height. Around the age of eight there evidently occurred a spurt of upward growth without a corresponding increase in weight. This is the only point where proportionately his height increase was greater than his weight increase. As can be observed in the figure, Denton, With this exception, is somewhat heavy for his height. It is noted several places in the record that he is "stocky." This observation, however, is not borne out by the inter— pretation of his Wetzel Grid. The evaluation of Denton's physical fitness according to the Wetzel Grid shows him advancing in height and weight constantly through the normal channels with some deviations. He drOps briefly into the lower normal channel around the ages of six, nine, eleven,and thirteen and one—half. Toward Growth A86 27 th- 7o 4. : e ; a 1 70 so 90 100 110 120 130 1. Age in Months Fig. 2. Comparison of Height and Weight 28 his fifteenth year he drops slightly into the "fair" column for a short period from which he returns to lower normal. Something may well have happened here to affect his growth; some illness or deprivation or possible Spurt in height. Physical growth is an indication of other health factors. If children are growing successfully, the chances are that {fmfi they are in a reasonably healthy state. There is no doubt but what size has an effect upon the child as a Whole. It makes a difference if he is not large enough to participate in certain activities or to handle himself when challenged by L others. If a child is ill-proportioned, obese or too thin, this is likely to affect his social and emotional adjustment. Men who are too short and women Who are unusually tall sometimes compensate in terms of personality. Fluctuations in weight are common and attributable oftentimes to minor causes while height is affected only by major factors and cannot so easily be controlled. ‘gL Mgntal Ability Denton Was tested for mental ability both by the school and by the research staff. Figure 3 shows the results of these graphically. It is quite significant to note that the tests he was given in school graph almost identically with the research project results. Table II shows his I.Q. ranging from eighty-five to lO9--highest at the first grade level and lowest at grades five and seven. In grade six he was scored 140 .L Norm _ ..........
