THE EFFECT OF LAB BASED INSTRUCTION ON ACT SCIENCE SCORES
By Michelle Hamilton
Standardized tests
, although unpopular
, are required for a multitude of reasons. One of these tests
is the ACT.
The ACT is a college readiness test that many high school juniors take to gain
college admittance.
Students throughout the United States are unp
repared for this assessment.
The average high school junior is three points behind
twenty
-four,
the ACT recommended score
, for the science section. The science section focuses on reading
text and
, interpreting graphs,
charts, tables and diagrams with an emphasis on experimental design and relationships among
variables. For students to become better
at interpreting and understanding scientific graphics they
must have vast experience
developing
the
ir own graphics.
The purpose of this study was to
provide students the opportunity to generate their own graphics to master interpretation of them
on the ACT.
According to
a t
-test the results show that students who are continually exposed to
creating graph
s are able to understand and locate information from graphs at a significantly faster
rate.

Pictorial representations and g
raphics
or diagrams that
represent connections between numbers,
points, lines, bars
are all around us. We see them everyday in newspapers, online, in textbooks,
in the media and especially on standardized tests (McBride 2009).
On average
, there are 1.38
graphics per page in
high
school
science textbooks and about 1.46 graphics per page in scientific
journals (Yeh
and McTigue
2009). Graphics
are extremely useful to display information quickly
and concisely. However, even with this overexposure to visual graphics and data there is s
till a
widespread lack of graph construction and interpretation in science courses (Tairab
and Al
-Naqbi
2010). With the
pressure on students to succeed
on standardized tests
science teachers
need to
rethink how
they
teach graph
construction and interpretat
ion in their
high school
science courses.
Standardized tests
are not
popular with the majority of teachers, students and parents
. In fact
, students think admission or ap
titude tests Òfocus on trivia, ask tricky questions and are not
relevant to what is tau
ght in schools
Ó (Bangert
-Drowns
et al.
1984). A survey of standardized
science tests
showed
that these tests do not
usually
measure studentÕs ability to think, but
rather
to memorize scientific fact
or to read text and graphics quickly (Morgenstern
and Renner
1984). Despite
the
unpopularity
for these standardized tests
they are here to stay. One common
standardized test is the America
n College Test
or ACT. This test is considered to be a college
readiness test
becau
se the ACT focus
es on
deep problem solving skills
and application of
knowledge
of learned skills
in the form of data manipulation,
and information analysis
(ACT Inc.
1996). The ACT is u
sually
given to
high school
juniors
or seniors
and it is
comprised of 5
sections:
English, M
ath, Reading, Science and Writing.
Each of the four multiple
-choice sections
(English, Math, Reading, Science
) are out of 36
possible points. These four multiple
-choice tests are then averaged to calculate an ACT
!!!%!!composite score
- also out of 36 possible p
oints. The writing score is out of a possible 12 points.
Each section of the ACT has
a distinct score that is deems test takers
as college ready by t
he
ACT organization
. The college ready score for
the English section is
an
18, the
math and reading
section
s have a college ready score of 22, the science has a college ready score of 23 and the
writing section does not have a readiness score
(ACT
2015). The English section of the ACT focuses on sentence structure, grammar, authorÕs purpose and
writing style. The math section of the ACT requires students to memorize and then utilize
common math formulas including simplistic math all the way up to trig
onomi
c functions. The
reading section focuses on reading comprehension of four different passages types
: prose fiction,
social studies, humanities, and natural sciences
. The science section focuses on reading and
interpreting graphs, tables, and other visual re
presentations of collected data
. In addition
, the
ACT Science test also expects student to compare and contrast
experimental designs, methods
and conflicting viewpoints
of different scientists
(ACT Inc. 1996)
. The ACT board describes this
portion of the AC
T as follows
: Òmeasures the interpretation, analysis, evaluation, reasoning, and
problem
-solving skills required in the natural sciencesÓ (ACT
Inc.
2015). The science portion
clearly involves science content, unlike the other ACT subsections. However, memo
rization of
facts is not required because all required information is presented to the students (Allensworth
et al.
2008). For students to be successful on the science portion of the ACT they must be able to interpret and
understand graphs in detail.
The ability to decode information presented in graphs
was deemed
Ògraphi
cacyÓ in 1965. Graphicacy
can be
explained as Òthe ability to read graphs, defining it as
proficiency in understanding quantitative phenomena that are presented in a graphical wayÓ
(Friel et al.
1996). Due to the unique nature of
the
ACT
science test
, and
its focus on graphicacy
, !!!&!!in addition to
the popular use of graphics in all print including journals, texts, and media
, the
science
portion
of the ACT
is the focus of this study.
It
has been very apparent over the last decade that our current Michigan high school students are
underprepared
for the ACT
, despite their desire to succeed.
In 2008, when
the
entire state of
Michigan required every junior to take the ACT
, the number of students that were college ready
in all subject areas was only 14.8%. In 2013 the number of Michigan juniors that were college
ready in all subject areas was 18.1% Finally, in 2014 the number of Michigan juniors that were
college ready in al
l subject areas was 17.8% while their average ACT score was 19.8 (Higgins
et al.
2014). The Michigan average for juniors in 2014 on the science section was 20.4, which is
significantly lower
than the state cut scores
by about three full points
(ACT 2015).
Looking specifically at Grand Ledge Public High School in 2014
, the mean ACT composite
score
of the tested juniors
was a 20.6
. This average is only about
one point
below
the state cut
-score.
Grand Ledge High SchoolÕs English score was 20
.0, which is abou
t 2 points above the
state cut
-score
. The juniorsÕ math average was a 20.1
- almost two full points below the state cut
-score.
Their
reading average was a 20.7
, again almost 2 full points below the cut
-score
. Finally,
the
juniors had
an average of 21.1
on the ACT science section
, which is
approximately
1.9 points
below the state cut
-score
(Michigan Department of Education 2015)
. The low scores at Grand
Ledge High School are unusual because the school is well known for its academic achievement.
These res
ults have led administrators and teachers to ask the following question: Òwhat can we
do as a school to help students improve their ACT scores?Ó
According to Slack and Porter
(1980)
, these standardi
zed or Scholastic Aptitude Test scores
can
be substantiall
y influenced as a result o
f coaching from educators
. Coaching is defined
as Òutilization of an aid or too
l by a test
-taker to acquire information and techniques for the purpose
!!!'!!of attaining the highest score possible on a testÓ (Stockwell
et al.
1991). Standardized test
coaching usually involves a lot of repetitive practice, simple test
-taking strategies, and exposure
to the testing format and old tests.
However,
continued
poor performance on the ACT
shows that current ACT preparation is not
working. Cur
rently students are focusing on the ACT as a last minute sprint, but this type of
preparation does little to no g
ood. The ACT requires years of developing and applying
learned
skills (Allensworth
et al.
2008). One study conducted in
the
Chicago School Dist
rict discovered
that th
e average English teacher spent
roughly
60% of their student
sÕ junior year preparing for
the ACT and about 40% of math and science
classes involve
some kind
of ACT preparation
. This
preparation
time was
usually d
esignated for practic
e problems,
practice tests,
and
test-taking
strategies. Despite these efforts Chicago Public Schools
saw a minimal
and insignificant
increase
in ACT scores
. These
small improvement
s on standardized tests
were
attributed to
increased
student familiarity of
the passages and timing
, which reduce
student anxiety and nervousness
(Fallows
1980). Poor test results
, despite preparation
, have
caused
teachers
to wonder
how they can
actually
impact
their student
sÕ performance on
standardized tests
, like
the ACT
, by coaching or teaching
if practicing the test is not enough.
The answer lies in the
type of practice and activities
completed by students.
A number of factors can influence the
increase in
ACT score
s including
the objectives of the activities or th
e appr
oach taken by the teacher in addition
to the studentsÕ
educational background (Scholes
and Lain
1997). When teacher coaching
occurs in addition
to
cooperative learning between students a significant increase in scores can be expected (Din
and
Soldan
2001). Therefore, just practicing for ACT or providing general coaching is not enough to
!!!(!!produce improvement in ACT
Science
scores. Instead co
-learning and activity based instruction
are
important for gains to occur.
To better prepare high
school students
for the ACT Science assessment teachers
must
focus on
analyzing data and
graph interpretation.
It is extremely important that students can interpret and
understand graphs on the ACT Science test. Therefore, science teachers must provide direct and
explici
t graph instruction pr
ior to the ACT. This is because
Ògraph instruction with a context of
data analysis may promote a high level of graph comprehension that includes flexible, fluid, and
generalizable understanding of grap
hs and their usesÓ (Friel
and Bri
ght 2001). However, many
high school teachers often neglect
graphic instruction and construction
because it is assumed that
pictures and graphics are self
-explanatory and require little if any clarification (Malmitsa 2008).
However, r
esearch shows that
hig
h school
students have not acquired graphing skills and they
are inadequate at using
and interpreting
graphs
(McKenzie
and Padilla
1986). When teachers
develop
materials to address this inadequacy they must first recognize the factors that affect
student u
nderstanding of graphics.
When deciphering tables and graphs there are a multitude of factors that determine
a student
Õs performance.
One of
these factors
is the complexity of data representation. For example, t
ables
are usually easier and more quickly
interpreted by stud
ents. Other factors
that influence data
interpretation
include the number of points, displays, configuration and trends within the dat
a.
One thing that can influence
success with these complex figures is the studentÕs experience,
which c
an provide
specific skills
to better understand and read graphics (Meyer
et al.
1997). Not
only is more graph experience needed but students need to
be provided with real world
applications. This is
extremely important
, because
having real life context of
graphs
helps
!!!)!!students learn significantly better (McBride 2009).
When implementing
real
-life graph
experiences the
graph fluency of students improve.
For
students to
be fluent in graphic interpretation
teachers
must focus on
three levels of
graphica
cy. T
he first level
focuses
on extracting
data from
a graph.
This level of graphicacy is
usually much easier for students
than determining relationships between variables
. The second
level
of graphicacy is of medium difficulty to students, because
it usually
involves interpolating
between points in the graph and determining
relationships in presented data.
Finally, the third
and most challenging level
of graphicacy
, involves extrapolation from the data and further
interpretation of the relationships identified i
n the graph (Friel
et al.
1996). The first level of graphicacy,
being able to quickly locate information on
a graph
, is common
ly
assessed on the ACT Science section.
These questions are embedded throughout
all three
distinct
science passage
types: Data Representation,
Research Summary
and Conflicting Hypotheses
. These low
-level questions are fairly easy to
answer
but are commonly missed by ACT
test takers. The most common mistake for students
on these questions occur
s due to
a lack of
math
knowledge, reading or language errors
, reading
graph
axes
or scales
wrong
. These mistakes are
usually due to rushing
(Friel
and Bright
2001). Tier two
(medium level questions
) on the ACT Science portion require
interpolation or
determining relationships between data sets.
These questions are also embedded throughout the
three passage types on the Science ACT.
These
tier two
questions seem to be more challenging
for students, because students must make inferences
, generalize or predict further outcomes from
the data (Friel
and Bright
2001). Generalizing
and
pre
dicting
usually requires higher
-level
thinking and problem solving
skills
. This type of
problem
solving
require
s students to draw
multiple pieces of informa
tion from the passage or graphs.
Anytime
more than one piece of
!!!*!!information
found within a
table or graph is needed to answer a question
student performance
declines (Bestgen 1990).
To reach
the
third level of graphicacy
it is extremely important for students to be able to
translate information between multiple graphics including tabl
es, line graphs, bar graphs, and
extrapolate information
. This
involves rearranging material, re
-sorting it
and extrapolating data
, requirin
g even more complexity for test
-takers.
Tier three graphicacy is
difficult
and
requires
student
s to
have logical reasoning ability, which is
not obtained until a
high sc
hool level (Wolff
and McGinn
1996). Therefore, during a studentÕs high school stay they
must be given deliberate
experience and training with graphs and other visual representations.
It is important to know that
it is not enough to only practice graphing with interpreting
. Students will not learn to use
graphics with repeated exposure to
them (Leinhardt
et al.
1990). Instead, s
tudents
need to Òactively participate in them
(graphs)
with their peersÓ (Wolff
and
McGinn
1996). Students
learn graphing
much better through their own engagement of graphing
tasks (Leinhardt
et al.
1990). This is be
cause s
tudents who are actively engaged in graphing
activities construct their own knowledge and increase understanding through participation (Patke
2013). Therefore, for s
tudent i
mprove
ment
to occur,
in all three
tiers
of graphicacy
, specific
scaffolded i
nstruction with continuous and diverse experience with graphics
is required in the
classroom
. Students need deliberate practice with the following aspects of graphing: interpreting
and highlighting trends, reading values, identifying tasks, and constructin
g graphs (Tairab
and
Al-Naqbi
2004). Of these items the most important aspect is graph construction
- students must
physically create graphs
. Graph construction is much more complex,
building
on interpretation
and
requiring
much deeper understanding
of the presented material
. To construct graphs s
tudents
must generate new
data
that
is not provided
by doing investigation
(Leinhardt
et al.
1990). !!!+!!Generating this new information helps student
s comprehend relationships better.
Constructing
graphs also r
equires students to develop higher levels of cognitive engagement.
The reason for
this is that gr
aph construction is very similar to putting together a puzzle which develops student
understanding of relatedness of the different variables being tested (Berg
and Smith
1994). Finally, g
raph construction allows students to mak
e predictions between variables,
which
permits
students to understand and quantify relationships
significantly better. Being able to quantify
relationships
is an integral part of experimen
tation
in the scientific community
(McKenzie
and
Padilla
1986). Students will be most successful with graph interpretation
and construction
when graphing is
paired
with
scientific inquiry
and hand
s-on science
(Yeh
and McTigue
2009). Hands
-on or inquiry science has a
variety
of positive effects on student learning.
For example, h
ands
-on or inquiry
science improves student attendance, work ethic, and attitude towards the material
. All
of
these outcomes
lead to better
student
success on standardized tests (Tretter
and Jones
2003). Inquiry learning
also
strengthens cognitive ability, provides students with a deeper appreciation
of science and helps
them
understand the fundamentals of science (Powell 2010). Finally,
inquiry
or hands
-on learning helps students retain information for longer periods of time and aids
students with logical approaches
to answer
ing
new questions with little background information
provided
(Patke 2013).
Not only does hands
-on inquiry
learning engage stud
ents and build their graphicacy it helps
students understand the scientific process better
. It also provides
motivation for utilizing
graphs
and identifying the
practical applications
for graphs
in daily life (Bestgen 1980)
. Part of
the
ACT
Science test re
quires students to critically think
about
presented scientific research,
experimental
design and
the validity of
collected data.
In fact, two of the three
ACT science
passage types
!!!,!!(research summary and conflicting hypothesis),
include concepts
that
require students to identify
proper scientific approach,
experimental design
and data analysis
. This part of the
Science
ACT
is best prepared for by
actually doing scientific laboratories, which involve
Òusing tools to
gather, analyze, and interpret data,
proposing answers, explanations and predictions (Turner
and
Rios
2008).Ó Inquiry or hands
-on science instruction
gives students the experience conducting
their own scientific experiments
, making them better prepared
to evaluate other scientific
experiments
and notice
inconsistencies or irregularities in
experimental design
(Tretter
and
Jones.
2003). With
the
increasing
availability of
technological information
it is imperative
that
students
improve their graphicacy so they have insight to ask critical que
stions
when presented data
(Aoyama 2007).
Research
shows that last minute prepping
and
learning general ACT strategies
is not significantly helpful for students on the ACT Science test
(Allensworth
et al.
2008). Improvement on the ACT Science portion
occurs when there is deliberate
and
direct instruction
on graphics. Furthermore,
practice and construction
of graphs and other visual aids is the best
method to positively
influence student
sÕ ACT Science scores.
It seems that t
he most growth
occurs whens s
tudents
are actively engaged in graphing
activitie
s. The purpose of this study is to
determine if participating in graphing activities
, including construction and interpretation
practice
, does improve ACT s
cience scores in high school students.
!!!$-!!GOALS AND OBJECTIVES
While teaching the science rotation of the ACT
Skills
class there were
two major goals.
The
first
goal was to increase
the ACT
student
Õs graphicacy including their
ability to create and
understand science information in the form of gra
phical representations
such as
tables,
single
-line graphs, bar graphs, and multi
-line graphs. The second goal was to increase
the
studentsÕ
ACT science score.
The objectives
for
the
twenty
-one day
ACT
rotation included: 1)
students
would
be able to
constr
uct simple graphs and be able to answer questions about their constructed graphs;
2) students
would
be able to quickly locate informati
on that is presented in any type of graph; 3
) Students
would
be able to
identify the relationship
s between multiple sets of data in terms of
direct vs. indirect or inverse relationships; 4
) Students
would
be able to skim the science ACT
passages when necessary to pull out important information when it is not directly i
ncluded in the
visual graphics; 5
) Students
would
be able to summarize the information in a provided passage in
their own words.
Three
different methods to
were implemented to
achieve these objectives.
First,
the ACT Science
section
was broken
down into mini
-lessons.
A particular graph
ic representation
was picked
that
was common on the ACT including tables, bar graphs, single
-line graphs, and multi
-line graphs
which were
briefly lectured on
methodology on how to approach
each type of
graphical
representation. Second,
hands on laboratory ac
tivities
were incorporated
allowing students to
collect their own data and then construct ACT like visual
aids.
The
students were expected
to be
more engaged in their own learning allowing for them to reach a higher level of understanding.
Third
, students
were exposed
to many
former
ACT passages
that included the same type of
graphical representation and
which had
them analyze the passages in the same ways they did
!!!$$!!with their own
collected
data. The expectation was that with all of this practice with constructing
and reading graphs
the
students would be able to in
crease their ACT Science scores and
graphicacy.
!!!$%!!CLASS DESCRIPTION AND DEMOGRAPHICS
This study was administered at Grand Ledg
e High School within the Grand Ledge Public
Schools District
in Grand Ledge, Michigan
. Grand Ledge
is a
moderately sized
suburban/
rural
school d
istrict located approximately 12
miles west
of downtown
Lansing, Michigan.
Grand
Ledge Public schools cover an area of 125 square
miles, which
includes Delta Mills, Mulliken,
Wacousta, Eagle and Delta Township. The majority of the district lies in Eaton County but also
includes parts of Ionia and Clinton Counties.
These communiti
es are made up of a population of
about 31,000.
As a result of this large and spread out area of residents
, there are many different
professions within the community. Many individuals commute from Grand Ledge to work in
Lansing, East Lansing and other town
s nearby. There is a mixture of professional, b
lue
-collar
workers,
and
farmers in
this area
. The population of
Grand Ledge consists of 52% wome
n and
48% men. The me
dian age of the population is 39
. The median income for a household is
$47,043, while the me
dian income for a family is approximately
$55,000. About 6.3% of the
families of the population live below the poverty line.
Grand Ledge school district was founded in 1886. Grand
Ledge
Public Schools consist of one
early childhood (Holbrook Early Childhood Center) and kindergarten center (Neff Kindergarten
Center), four elementary schools (Wacousta Elementary, Beagle Elementary, Delta Center
Elementary, and Willow Ridge Elementary), one
middle school (Hayes) and one high school. In
total
, roughly
5,300 students attend Grand Ledge Public Schools with approximately 1
,700 students
at the high school
. The student population is
88 percent Caucasian, 5.9 percent African
American, 3.2
percent H
ispanic, 2
.1 percent Asian, and 0.
4 percent
of other ethnicity. The high
schoo
l has a graduation rate of 88.97
percent
and o
f the students that graduate 90 percent
of them
continue education after high schoo
l. Within the district about 26
percent
of the
student
!!!$&!!population receives free or reduced lunch.
12.6% of the population at Grand Ledge qualifies
for
disability services.
Grand Ledge Public Schools have a teacher to student ratio of about
twenty
-four
students
to one
teacher
. As
a result
of the 2013 and 2014 ACT results
, Grand Ledge High School
has been deemed a red
district
by the state of MichiganÕs accountability scorecard (MI School Data 2015).
A red district
is one
that does not meet their targeted learning goals appropriated by the
state of Michigan.
In response to
the red school status
, the administration at Grand Ledge High Scho
ol decided to
implement an ACT S
kills class
for
the 2014
-2015 school year. The
expectation
for this course
was to prepare
students
for the ACT
and improve t
heir ACT scores in all subtests
. All
Grand
Ledge High School sophomores
were gi
ven an ACT practice test in the spring of 2014. A
ny student that received a
n ACT composite score between a 12 and 20
was required to take
the
ACT
skill class during the
following year
(2014
-2015). Students were removed from one of their
chosen elective courses and involuntarily placed into this ACT Skills course.
The
ACT Skills
class consists of three seventeen
-day rotations. One rotation covered
English
and r
eading
strat
egies
involving lots of
pract
ice and direct instruction from a certified English teacher. T
he
second rotation focused
on math preparation
taught by a certified math teacher. The final rotation
introduced
the science
-reasoning
subtest and focused on
graph i
nterpretation
and construction,
taught by a certified science teacher
. The ACT Skills class was considered a credit/no credit
class, in which
students had to complete all coursework to receive credit in the
class. At the end
of the trimester
students were
given a full
-length ACT post
-test and
could select a letter grade
based on their post
-test composite
score. A
composite score of a
21 or above would allow a
student to receive
a letter grade of an A. A
19 or 20 on the post
-test would grant a student a
letter
grade of a B and
if a student scored a
17 or 18 they could choose a C. F
inally
, any student
!!!$'!!receiving a 16 or
below
would only gain credit if they completed all of their coursework.
In this
study we will focus on the results of
the
three
-week scienc
e rotation only.
The study was conducted
in
six different classes of about twenty students
each
between
September 2014 and December 2014.
There were 72
students involved in this study, all of
whom
signed the
Parent Consent and Student Assent Form
(Appendi
x A). This group of students
represented
approximately 4% of the high school population. 100 percent of these
seventy
-two
students were juniors.
This student population was targeted because they did not meet the state
cut score of an ACT composite score of
21.25 during their spring 2014 pre
-test. The ACT
composite score is an average score of all subsections of the ACT including
- English, Math,
Reading and Science. The state has determined that a
student scoring
23 and over
on the ACT
Science portion is considered college ready. Despite none of these students meeting the state cut
score for ACT composite
, two students
in the study
were
already
college ready for the science
subsection of the ACT. Of the 72
students participat
ing in the study nine of them were special
education students
, which is thirteen
percent
of the
student
population.
55 percent of the students
were males and 45 percent were females. This group of individuals is
fairly
representative of the
entire school
population.
!!!$(!!IMPLEMENTATION
To begin
the
ACT Science rotation each student
in all six classes
took an ACT Science pre
-test which can be found in the supplemental material document C
. The pre
-test was proctored exactly
like the actual ACT
. It consisted
of 40 questions,
and
35 minutes was allott
ed for the students to
finish the pre
-test. Students were asked to try their best and were not given any help or
clarification on any questions. After the initial pre
-test the ACT Science unit began.
The focus of
the science rotation was graph interpretation
, understanding
and construction
. Activities included ACT practice sets, vocabulary building
, and labs including data collection
followed by
graph construction
(Supplemental
Materials C
). During each mini
-unit
students were
presented with a lecture that included explicit instructions
on how to read and interpret each type
of visual representation (i.e. tables, bar graphs, etc). After the lecture students participated in
one
or more hands
-on laboratories
. These
laboratories
included pre
-formulated
ACT like follow
-up questions,
which
focused on all three tiers of graphicacy
with a major focus on relationships
between variables
. Following
these laboratories
each s
tudent worked individually on one or more
practice A
CT passage
s that focused on the same type of visual representation
(i.e.
bar graphs)
. Students were then given
solutions to each ACT practice
set. After
these activities
containing
a specific
learning
target
, the students were given a quiz over that type o
f visual graphic.
The
quizzes
(Supplemental materials
A)
contained the former ACT pa
ssages the students practiced,
but with completely different questions.
Once the quiz was completed and corrected the next
mini
-unit began.
In addition to these mini
-units
throughout the three
-week science rotation,
typical
ACT science vocabulary was embedded into the curriculum.

!!!%-!!REVIEW OF
GRAPHING ACTIVITIES
All six classes were presented the same activities over their ACT Science rotations.
In total there
were six hands
-on labs used during the seventeen
-day unit. The first two activities targeted
construction of data tables. The first lab
(Supplemental Materials
A1)
required students to collect
data on different types of solutions. Q
ualitative
data
were
collected including
physical
observations
such as
odor, color,
and
texture
. Quantitative data
were
also collected including:
pH,
the solutionÕs
effect on red
and blue
litmus paper
. The second activity
(Supplemental
Materials
A3)
was a
student measurement survey. Within this activity each student worked in
groups of three or four and collected qualitative data including: t
-shirt color, student name, hair
length (short, medium, or long), etc. and quantitative data including: arm span, he
ight (cm), age,
etc. All of
these
data
were
collected and placed into one
large
data table.
The third activity
(Supplemental Materials
A5)
targeted bar graphs.
Students
completed an
online simulation to determine what affected the
pendulumÕs period
. This a
ctivity used the PhET
Interactive Simulations pendulum simulator developed by the University of Colorado
(http://phet.colorado.edu/sims/pendulum
-lab/pendulum
-lab_en.html).
Students altered two
different
variables:
pendulum length and
mass. Students constructed a data table and then
completed two different bar graphs comparing a pendulumÕs period to the height in
the first
graph
and a pendulumÕs period to the
mass in the
second graph
. The fo
urth activity
(Supplemental Materials
A8)
address
ed single
-line graph practice. Students
worked as a group in the hallway to record the time it took for a bowling ball to travel down
a hallway. Each student stood at a
different tile in the hallway and recorded the amount of time it
took for the bowling b
all to cross their tile. Students
recorded
the
se data into a table and then
constructed two separate single
-line graphs. The first line graph compared the distance the
!!!%$!!bowling ball travelled to the time, while the second line graph compared the number of t
iles passed to the travel time.
The fifth and sixth activities targeted
strategies to generate a multi
-line graph
. The fifth activity
(Supplemental Materials
A11)
required students to soak different
ÒgrowÓ toys in different
solution
volumes
and types over
48 hours to determine the percentage of increase in weight,
width and length. Students collected these three measurements before and after
soaking the grow
toys
. Students then had to calculate the percentage of increase in size by comparing their toyÕs
measurements before and after including the masses, widths and lengths. All of this information
was collected and placed into one data table. Students then graphed
these
data onto three
different graphs
, one comparing solution
volume
to the percentage of mass increase, another
comparing solution
volume
to the percentage of width increase, and their last graph comparing
solution
volume
to the percentage of length in
crease. Each of these graphs had
three different
lines one for each type of solution (sugar water, distilled water and tap water). The sixth and
final lab activity
(Supplemental Materials
A13)
required students to construct
a multi
-line graph
from pre
-exist
ing data. Each student was given N
ational
Oceanic
Atmospheric
Administration
(NOAA)
weather
data from Lansing during 2013.
These
data included relative humidity,
maximum average temperature and precipitation. Students graphed
these
data for every month
during 2013. This graph was particularly interesting because students needed to construct three
lines on the same graph using three different y
-axes.
!!!%%!!TRACKING STUDENT PROGRESS
Students were tracked regularly throughout the
seventeen
-day
science rotation.
Students
submitted their labs after completing them
so they could be photocopied
for use in this study
. The original labs were then returned to students and we
re corrected
, in detail, during
class.
Students were expected to correct their
work and fix any mistakes that they made with the
follow
-up questions or graph construction.
Students were required to keep all of their materials
for the course in an ACT binder. To further monitor student progress and class participation
students were r
equired to submit their binders two times during the science rotation for a binder
check. Student binders were reviewed and
scored as
credit or no credit and then returned the
following day. To receive credit students had to complete all coursework and hav
e corrections
written on all of their labs or ACT practice sets.
If students did not complete all of their
coursework they could not receive credit in the class at all.
Of the 72 students included in this
study
all 72 students received credit for the ACT b
inders.
!!!%&!!ASSESSMENTS
Assessments for the science rotation included
one pre
-test, four mini
-quizzes and one full
-length
ACT post
-test (Supplemental Materials C
). The pre
-test was an old full
-length ACT Science test.
The mini
-quizzes consisted of two or three former ACT passages
that
included the targeted
visual representations. The first mini
-quiz
(Supplemental Materials C
1) focused on the student
sÕ ability to interpret tables, the second
(Supplemental Materials C
2) focused on bar graphs, the
third
(Supplemental Materials C
3) focused on single
-line graphs, and the last mini
-quiz
(Supplemental Materials C
4) focused on multi
-line graphs. Despite these post
-tests being only a
portion of the actual ACT
, the scores were
calculated using the
scored
percentages and these
were
compared to the standard ACT chart
(Supplemental Materials C
5) and
were
scored
out of
36 possible points.
The post
-test (Supplemental Materials C
6) was identical to the pre
-test and
also was scored
out of 36 possible points
. At the end of the ACT Science rotation an anonymous student survey
(Supplemental Materials
C7) was administrated
. Students were asked a variety of questions about the science rotation.
Some of these were general questions that f
ocused on the helpfulness of the ACT Science
rotation. Other questions were more specific about what activities
were helpful or not
. Approximately one third
of
the
student
s in this study
discussed their thoughts about the graphing
activities their
responses
are shown
in Table 2 in the data and re
sults section of this paper
. !!!%'!!RESULTS AND ANALYSIS
On the first day
of the ACT science rotation students were given a pre
-test (Supplemental
Materials C1
) to
determine baseline information about
their
prior ability on the ACT Science
section
. This pre
-test was comprised of a previously used ACT Science section
, which contained
tables, pictures, bar graphs, single li
ne graphs and multi
-line graphs
. The
ACT science rotation
students were given an identic
al post
-test at the conclusion of this section
. Their scores were
analyzed and a t
-test was done with p= 0.05
. Figures 1
-5 show
comparisons of the pre
-test data versus the
mini
-lesson quizzes and the post
-test scores for all students who volunteered to par
ticipate in the study.
Figure 1 compares the
ACT Science pre
-test scores to the ACT Science post
-test scores of all 72 study participants.
Figure 2 compares the ACT Science pre
-test scores to the tables practice quiz. Figure 3 compares
the
ACT Science pre
-test scores to the bar graph practice quiz. Figure 4 compares the ACT
Science pre
-test scores to the single
-line graph practice quiz. Finally, Figure 5 compares the ACT
Science pre
-test scores to the multi
-line graph practice quiz.
All quiz and test averag
es improved
from pre
-test to post
-test. Tests and quizzes were graded using a standard ACT scale ranking
students betwe
en 1 and 36 points,
Appendi

has details on
how the ACT score is scaled
. A
scatter plot was chosen to present data so individual improvement from the pre
-test to post
-test and mini
-lesson quizzes could be seen.
!!!%(!! Figure 1 shows
that of the 72 students
assessed 57 students increased their ACT scores, while
nine studentÕs ACT science score decreased
(students
2, 12, 14, 51, 58, 60, 61,67 and 70)
and six
student
Õs ACT science score remai
ned the same
(students 13, 18, 32, 52, 54 and 55)
. Of the 57
students who improved their score twelve students signifiicantly raised their score
by six or more
points
(students: 5, 11, 16, 21, 26, 28, 31, 40, 43, 51, 69, and 72)
, while nine students only raised
their score by one point (students: 4, 10, 23, 25, 35, 37, 41, 47, and 59).
As a whole group the
average pre

!!!&-!!In addition to these assessments
, individual graphing activities were collected
including
a pH lab,
Pendulum Lab, Bowling Ball Lab, Grow Toy Lab, and Meteorology Lab Graphing Activity
(Supplemental Materials
B). Every student in this study completed
all of the
graphing activities
mentioned in Table 1
. With the
constructing
table labs
(pH lab and student measurement lab)
students did not make many
, if any
, mistakes entering data
into their tables
. On these labs some
students underlined or highlighted main ideas (
Supplemental Materials
B1 and B2)
, but few
students marked up their table
s to find the data attached to follow
-up ACT like questions. With
the bar graph
(pendulum lab)
activity
no students made any graphing errors
. An exemplar
example of this lab
is shown
in
Supplemental Materials
B3. The bowling ball lab focused on
single
-line
graphing. With this graphing activity students did have a
difficult
time plotting the
data points.
This was most likely due to
the
unique units
of the collected data
. Students had
trouble plotting a point, because they were unsure where to place their dat
a points. Another issue
students had
while completing this lab was
drawing
a best
-fit line. A lot of the students just
connected the dots and did no
t even attempt to create a best
-fit line as
shown
in
Supplemental
Materials
B4. Supplemental Materials
B5 sh
ows an exemplar example of the
bowling ball
lab. Another interesting point about this lab is that s
ome students who had already taken physics
actually wrote down the formula
for velocity even tho
ugh there was no need for math
(Supplemental Materials
B6). The multi
-line graphing activities
(grow toy lab and meteorology
graphing lab)
contained the most student graphing errors. One unusual mistake
was made within
the
grow toy
lab. One
student graphed the mass, length, and width before and after in a
compari
son plot (
Supplemental Materials
B7). This graph should have only included the
percentage increase of these measurements. An exemplar student example for this lab
presented
in Supplemental Materials
B8. The last graphing activity
(meteorology lab)
involved
plotting
!!!&$!!already collected data
. The most common mistake on this graphing activity
was students
connecting data points out of order as seen in
Supplemental Materials
B9. An exemplar student
example for this lab can be found in
Supplemental Materials
B10. Table 2
includes a select group of statements collected from the anonymous survey given at the
end of the ACT Science rotation. The entire set of survey questions can be found in Appendix
D7.
The
purpose of this survey was to get feedback from students abo
ut the activities
completed
and materials
used
in the class
. The surveyÕs main focus was to question students about what
specific activities
were
helpful and unhelpful
to them
. It was also conducted to see how students
felt about the ACT Science section after their completion of the ACT Science rotation.
Almost
twenty percent of
students felt that the laboratories were not helpful. Only
about 7% of the polled
students
thought t
he laboratories were beneficial. It is important to note that o
nly the statements
that discussed the laboratories or hands
-on activities were included in this paper
; therefore, only
a portion of
students
responses were included.

!!!&&!!CONCLUSION
Overall the data show
that compared to the pretest
, on average students improved their ACT
score on all of the mini
-quizzes and the post
-test (Figures 1
-5). Comparing the pre
-test to the
post
-test, a paired T
-test (p= 0.05) was conducted. Results show that all pre
-test data compared
to the mini
-quiz data and the post
-test data are statistically significant, showing that there is a
difference between the pre
-test and each of the quizzes and post
-test.
However, there was a much larger increase in scores between the pre
-test and mini
-quizzes than
between the pre
-test and post
-test. These results are most likely due to the level of difficulty of
the types of que
stions on each mini
-quiz. The first mini
-quiz focus was tables
(Figure 2)
. This
quiz had the largest student growth
, probably because tables are easier for students to interpret
and understand (Meyer
et al.
1997). The second mini
-quiz focused on bar graphs
. This quiz
showed the second highest student growth again this material is usually easier for student to
approach in a timed situation
(Figure 3)
. The
third
and
fourth
mini
-quizzes had approximately a
three
-point increase of student growth
(Figure 4 and 5
). This growth is much lower than the
student growth for the tables and bar graph mini
-quizzes, which may be attributed to the level of
difficulty of the material. Generally, speaking line graphs are more challenging for students
because they require deepe
r level thinking.
This is because students must look at the graph as a
whole to gain meaning of the relationships between the variables
requiring well
-developed
problem solving skills
(Leinhardt
et al.
1990). Another factor that may have influenced scores
is the length of assessment. Each of the mini
-quizzes was only a portion of the actual ACT Science test. The first three mini
-quizzes consisted
of two passages each. The ACT science test appropriates students only five minutes to complete
a passage. There
fore, these three mini
-quizzes were only ten minutes in duration. The forth mini
-!!!&'!!quiz consisted of three passages and was fifteen minutes in duration. The post
-test was a full
-length ACT Science test, which includes seven passages and lasts for 35 minutes.
Since the post
-test is longer than the mini
-quizzes test fatigue may have impacted these results. Students may
have had a harder time focusing for a longer period of time. Also the post
-test included all types
of graphics including tables, bar graphs, sin
gle
-line graphs and multi
-line graphs. Some students
might have weaknesses in one or more of these areas that did not affect the individual mini
-quizzes.
Finally,
one last
factor that influenced student success was motivation. Some students were not
motiv
ated to improve their ACT scores. One reason students may have lacked motivation was
their post
-high school plan. Students in this course that are not planning on attending college saw
little value or worth in an ACT Score so they did not try as hard
as th
ose planning to
. Another
reason for lack of motivation was the involuntary enrollment in this course. A handful of
students were upset or annoyed that they could not take an elective class because they had to take
the ACT Skills class. Due to this lack of
motivation, some students did not utilize their class time
well. In fact, some students completed the mini
-quizzes and post
-test well before time was
called. This lack of effort would have impacted the student growth averages.
Despite
the significant improvement
on the ACT Science post
-test,
many students did not
attribute that to the hands
-on inquiry labs. In fact, the majority of students thought the labs did
not help them in any
way. Some students described the uselessness of the la
bs because they
already knew how to collect data and create graphs. The majority of students that thought the
labs were not helpful explained that it was because they did not have to do it on the actual ACT
test.
Students had a hard time
determining
the
importance of the hands
-on labs. A
s a result of this
in the future I would be more explicit in explaining why we are doing hands
-on activities to
!!!&(!!students.
Despite the
unpopularity of the labs
among
the students, some students did express
their interest in t
he labs. The students that did enjoy their labs had a variety of reasons including:
helped with attention span, the labs provided an application of the ACT questions, the labs were
fun, and they were hands
-on. When labs were conducted students seemed more
engaged and
student participation was increased. In addition, students asked more questions about the
relationships between the measured variables, which promoted deeper understanding.
Looking at all of the
data
together there is a strong indication
that
student success on the ACT
Science section was impacted by the hands
-on graphing activities and the other practice that took
place.
This is most likely because when students actively engage in hands
-on science it increases
their understanding of the scienc
e and it helps them process information more successfully
(Patke 2013).
It seemed that the activities were effective in
meeting both of my goals: improving
ACT science scores and increasing student graphicacy.
Students not only improved their ACT
science
scores, but they got better at each graphing activity throughout the science rotation.
These gains were a direct result from the hands
-on activities, which increased student knowledge
and strengthened their ability to apply concepts to new data sets and gr
aphics (Powell 2010).
Student graphicacy can only improve from direct d
ata collection and construction
, because this
engages students and promotes high
-level thinking (Leinhardt
et al.
1990). Due to the significant gro
wth of student ACT Science scores
I would repeat these activities in an
ACT Skill class in the future.
However, there are a few areas I would reconsider addressing.
First, I would be more intentional when discussing the purpose of the hands on activities to my
students. Second, the pace of t
he course seemed very fast and rushed at the end of the science
rotation. In the future, it may be worthwhile to decrease the number of assessments given during
the class period. For example, giving a second pre
-test during class does not seem as beneficia
l !!!&)!!as using that class period for content. Finally, I would like to increase student involvement in
planning and running the different trials in each lab that we do. I think that increasing student
involvement in the process of science would increase their
scores even further.
Even with the success of this ACT Skill course
, unfortunately,
this course will not be taught
again at Grand Ledge High School. This is because
the State of Michigan has chosen to replace
the ACT with the SAT.
The SAT
will be completel
y revamped and will look brand new starting
in September of 2015.
The newly refurbished SAT should be similar in appearance to the ACT,
but it will not contain a science portion.
The science questions will be embedded into the reading
and math sections of
the SAT. This will change how general test taking strategies would be
taught in the science rotation. Due to the implementation of a new SAT test f
urther research is
necessary to determine if similar hands
-on graphing activities would also positively impac
t SAT
scores.
!!!&*!! APPENDIX
!!!&+!! Parental Consent and Student Assent Form
Dear Students and Parents/Guardians
I would like to take this opportunity to welcome you to my classroom and invite your son or
daughter to participate in a research project.
Utilizing scientific graphing and a laboratory
based approach to improve Science ACT scores in High School Students
, which I will
conduct as part of ACT preparation course this trimester. My name is Michelle Hamilton and I
am your studentÕs ACT preparation course teacher for the first trimester and I am also a masterÕs
degree student at Michigan State University. Researc
hers are required to provide a consent form
like this to inform you about the study, to convey that participation is voluntary, to explain the
risks and benefits of participation, and to empower you to make an informed decision. You
should feel free to ask
the researchers any questions you may have.
What is the purpose of this research?
I have been working on how to better teach the scientific
method to high school learners and I plan to study the results of this teaching approach on
student comprehension
and retention of the material. The results of this research will contribute
to teacherÕs understanding about the best way to teach about science topics. Completion of this
research project will also help me to earn my masterÕs degree in Michigan State Univ
ersityÕs
College of Natural Science.
What will students do?
Students will participate in the usual instructional curriculum for the
ACT preparation course but with added guided and open ended
graphing and chart reading
activities throughout the first trimester. Students will complete the usual assignments, class
demonstrations, pretests, posttests, laboratory experiments, and activities as they would for any
other unit of instruction. There ar
e no unique research activities and participation would not
increase or decrease the amount of work that students normally do. I will simply make copies of
studentÕs work for research purposes. This project will take place in the fall of 2014 and continue
throughout the first trimester of ACT preparation. I am asking for permission from both students
and parents/guardians (one parent/guardian is sufficient) to use copies of student work for my
research purposes.
What are the potential benefits?
My reason f
or doing this research is to learn more about
improving the quality of science instruction. I will not know about the effectiveness of my
teaching methods until I analyze my research results. If the results are positive, I can apply the
same teaching metho
ds to other science topics taught in this course, and ACT preparation
students will benefit by better learning and remembering the course content. I will report the
results in my masterÕs thesis so that other teachers and their students can also benefit fr
om my
research.
What are the potential risks?
There are no foreseeable risks associated with completing course
assignments, class demonstrations, pretests, posttests, laboratory experiments, and activities. In
fact, completing coursework will be very bene
ficial to students.
The consent forms were held
anonymously in locked file cabinet that will not be opened until after I have assigned grades for
this trimester.
That way I will not know who agrees to participate in the research until after
!!!&,!!grades are issu
ed. In the meantime, I will save all of the written work. Later I will analyze the
written work for students who have agreed to participate in the study and whose
parents/guardians have consented.
How will privacy and confidentiality be protected?
Inform
ation about you will be protected to
the maximum extent allowed by law. StudentÕs names will not be reported in my masterÕs thesis
or in any other dissemination of the results of this research. Instead, the data will consist of class
averages and samples o
f student work that will not include names. After I analyze the data to
determine class averages and choose samples of student work for presentation in the thesis, I will
destroy the copies of studentÕs original assignments, tests, etc. The only people who
will have
access to the data are the thesis committee at MSU, the Institutional Review Board at MSU and
me. The data will be stored on password protected computers and in locked file cabinets in
locked offices on MSU campus for at least three years after
the study.
What are your rights to participate, say no, or withdraw?
Participation in this research is
completely voluntary. You have the right to say ÒnoÓ. You may change your mind at any time
and withdraw. If either the student or parent/guardian reques
ts to withdraw, the studentÕs
information will not be used in this study. There are no penalties for saying ÒnoÓ or choosing to
withdraw.
