IN MATHEMATICS AT THE 8TH GRADE LEVEL

Josefino G. Saclao
ABSTRACT
There are two groups, the control and the experimental, each with 45
students, for a total of 90 students from Pulong Buhangin National High School.
One group was taught using the SIM-MOD while the other was not. Both the
groups were pre and post tested. Further, detailed statistical analysis was
conducted for data analysis.
There has been a pattern on the preferences of the participants with regards
to the design of the SIM-MOD. Most of them have been attracted to the distinct
design of the learning materials and they found the tasks contained in the SIM-
MOD not that easy to accomplish. There has also been a pattern on the
preferences of the participants with regards to the delivery of the intervention
program on “Rational Expressions”. Majority of them have appreciated the support
provided for them before, during and after the intervention program. Most of them
have found the allotted time per session, per week, not enough for them to
accomplish the tasks contained in the SIM-MODs.
The independent sample t-test shows the scores of the control and
experimental groups on the pretest do not have significant differences before the
SIM-MOD was used by the experimental group (p-value is 0.855). Upon using the
SIM-MOD, a posttest was given to the participants. The p-value of 0.000 with a t-
value of -11.019 is an indication of the significant differences between the scores
of the participants from the control and experimental groups. This implies that the
participants who used the SIM-MOD have significant higher scores than those who
did not use the learning materials. Also, there is a significant difference (p-value of
0.000 and t-value of 7.727) present in the mean gain scores of the participants
with regards to their pretest and posttest scores. This is an indication that the use
of SIM-MOD is an effective way of improving the achievement of the students in
their Mathematics subject.

The study recommends teachers to develop and use SIM-MOD in other
topics in Grade 8 Math. Conduct similar studies on the use of SIM-MOD in other
discipline. Use SIM-MOD as a remediation material to enhance the academic
achievements of low performing students in Math and as enhancement material to
furtherly improve the cognitive skills of above average and average type of
students in Math and in other discipline. Encourage administrators, mathematics
supervisors, and teachers to make SIM-MOD in all topics not only the least
mastered skills in a given subject area. Teachers shall be provided with more
seminars and workshops on the principles of SIM-MOD construction.
Rationale
Today, mathematical methods pervade literally every field of human endeavor and play a
fundamental role in economic development of a country. In our journey towards scientific and
technological advancement, we need nothing short of good performance in Mathematics at all
levels of schooling. Unfortunately, performance of students in Mathematics at the end of secondary
education has not improved in the past decade (NAT 2005-2015).
There are many possible reasons for this. One is that many students have a weak
foundation with rational numbers and so are unable to handle something that looks like a “fraction
with x’s on it.” Another reason is the students’ inadequate skills on factoring, most particularly
Factoring Trinomials of the form x2 + bx + c where the numerical coefficient of x2 is one (1) and the
other type of Factoring Trinomials of the form ax2 + bx + c, where the numerical coefficient of x2 is
greater than one (1). One last reason is the scarcity of effective learning materials. It is along this
light that the researcher was motivated to develop learning materials to be able to address these
problems encountered by some Grade 8 students of PBNHS.
Page 3 of 70
These learning materials are called SIM-MODs. SIM-MOD is a combination of strategic
intervention materials and modular instructions. These SIM-MODs were evaluated by the experts
and the respondents themselves and the impact of these SIM-MODs to some Grade 8 students
were likewise investigated.
Bunagan (2012) defined Strategic Intervention Material (SIM) as meant to reteach the
concepts and skills (least mastered). It is a material given to students to help them master
competency-based skills which they were not able to develop during a regular classroom teaching.
It consists of both learning strategies (for students) and content enhancement (for teachers). It is
multifaceted approach to help students to become independent and successful learners. He further
differentiated SIM and modules. This intervention material (SIM) focuses on the skill not mastered
by students during regular class. It does not involve pretest and posttest and includes fun activities.
Module, on the other hand, contained different topics included in a given chapter and intended for
regular classroom teaching and distance learning. Module requires pretest and posttest and also
includes fun activities. A SIM may have six parts and these are: title card, guide card, activity card,
assessment card, enrichment card and reference card. On the other hand, a module may contain
the following parts: statement of purpose, desirable skills, instructional objectives, pretest, learning
activities, posttest, and answer key.
The combination of Strategic Intervention Material (SIM) and Module otherwise known as
SIM-MOD is a two-in-one packet of learning materials used for remediation and enhancement
purposes, consisting of cognitive objectives, a sequence of activities, and provisions for evaluation.
These packets of materials aimed at enhancing poor achievements of the learners, are
learning materials developed by the researcher. This contribution of his which he considered to be
one of the latest innovations in the field of Mathematics education has combined features that of a
SIM and a module. The objectives are written in cognitive terms and are specific. The sequence of
learning activities is designed to:
There had been a number of conducted researches that proved the effectiveness of
intervention materials and other related strategic and modular approach. Some of them are as
follows:
Arora and Singh (2005) conducted research on Development and Evaluation of Self-
Learning Modules to Enhance the Traditional Physiology Class at CMC Ludhiana. The results
(posttest average of 84%) indicated that Self-Learning Modules to enhance were an effective
method of studying and reinforcing learning. Comparison with other teaching methods indicated
that the students would prefer Self Learning Modules as an additional method of learning but not a
replacement for lectures and textbooks. Students recommended that SLM experiment should
continue and suggested an SLM library for self - study.
Soberano (2010) mentioned that Strategic Intervention Materials were effective in mastering
the competency based skills in chemistry based on the mean gain scores in the posttests of the
experimental and control groups. He found out that there was a positive transfer of learning in both
the groups. However, the higher mean was observed from the experimental group after the
presentation of the intervention materials.
The study conducted by Togonon (2011) on the development and evaluation of Project-
Based Strategic Intervention Materials (PB-SIMs), PB-SIM is a valid instructional material in
teaching high school chemistry. Results showed a significant difference between the achievement
of the students before and after being exposed to PB-SIMs.
The study of Escoreal (2012) on Strategic Intervention Material as a tool to reduce least
mastered skills in Grade 4 Science, concluded that SIM provides baseline information and should
be implemented to avoid marginalization of pupils. Her study also indicated that there is a significant
reduction in the pupils’ mean number of least mastered skills after SIM implementation.

Salviejo, Edwin I, Arcanes, F. and Espinosa, A. (2014) on their study on Strategic
Intervention Material – Based Instruction, Learning Approach and Students’ Performance in
Chemistry revealed that the use of SIM-BI is effective in terms of improving students’ performance
and learning approach. The surface learners performed equally well as the deep learners when
SIM-BI was used. The positive result of the survey suggested that the SIM was appreciated and
appealed to both types of learners.
The traditional curriculum focused on the teacher rather than the learner. However, in recent
years, there has been a paradigm shift taking place, moving the emphasis from teaching to learning
a more student-centered curriculum. This change has impacted on the curriculum design process
with a greater emphasis on the learning in terms of knowledge, skills and competencies within
intervention/ learning materials. The focus is on how learners learn and the design of effective
learning environment.
Even the best designed intervention/learning materials, with very worthwhile defined
learning outcomes, can fail if the teaching strategies employed are inappropriate to encourage and
support the learners towards meeting the desired learning outcomes (Ramsden, 1992).
Toohey (1999) defined a teaching strategy as “a plan for someone else’s learning, and it
encompasses the presentations which the teacher might make, the exercises and activities
designed for students, materials which will be supplied or suggested for students to work with, and
ways in which evidence of their growing understanding and capability will be collected.”
The question remains when designing modules for learning, why is it important to be aware
of the theories the underpin learning? A theory should make explicit the underlying psychological
dynamics of events related to learning. Each theory is based on different assumptions about the
nature of learning and it is suggested that one should identify his own theory of learning because
the strategies one might use to enhance learning will directly follow from one’s orientation.
In addition to taking cognizance of different learning theories, it is also important to take into
account that there is no universal way of learning. Brown and Atkins (1991) state that differing
students will use different strategies on different tasks. They stress the importance of ‘learning-for-
understanding’ and ‘learning-for-knowledge’ orientations, with learning being a continuous process
of development back and forth between the two.

providing opportunities for students to pursue topics in depth so that they can understand the
material for themselves;
ensuring an appropriate formative and summative assessment strategy.
These ideas resonate with teachers in today’s secondary education environment and have
implications both for choice of learning and teaching strategies and how one assess learning. An
awareness of these approaches to learning is fundamental to the entire intervention/ learning
material design process.
The fundamental principle of constructive alignment is that a good teaching system aligns
teaching method and assessment to the learning activities started in the objectives so that all
aspects of this system are in accord in supporting appropriate student (Biggs 1999:25).
There are three elements involved in the process of constructively aligning a module:
1. Defining the learning outcomes;
2. Choosing the learning and teaching methods that can lead to attainment of outcomes;
3. Assessing student learning outcomes.
The following approach will help one to think through and decide on appropriate teaching
strategies for developing learning materials. First, take time to read over the materials aims,
learning outcomes and content material. Then, focus on how best one can involve students in
making sense of the material through active engagement and application.
According to Blair (1998), students achieve at a higher level in their work if they are directly
taught by their teachers. In the Direct Instruction (DI) model, the teacher assumes the major
responsibility for the lesson’s progress and practice flexibility by adapting the class activities and
lessons to their students’ age and abilities. The teacher explains, demonstrates and monitors
progress of the students.
Research has shown that effective teachers clearly explain to students what is expected to
them prior to beginning of instruction.
Page 8 of 70
Research has shown that low level questions are most effective with at risk
students.
Basic Skills, Facts and Knowledge that a teacher must do:
Organizing content – the content to be learned must be selected and then analyzed
according to the learners’ needs
Lectures – often an essential part of the classroom instruction and one way in which new
material is delivered to students
Demonstrations – visual examples work particularly well in the presentation stage of this
model
Student practice takes place with teacher guidance
High frequency of questions and overt student practice (from teacher and/or materials)
Questions are directly relevant to the new content or skill
Teacher checks for understanding by evaluating student responses, then teacher gives
additional explanation, process feedback or repeats explanation – where necessary
All students have a chance to respond and receive feedback; teacher ensures that all
students participate
Prompts are provided during guided practice (where appropriate)
Initial student practice is sufficient so that students can work independently
Guided practice continues until students are firm
Guided practice is continued until a success rate of 80% is achieved
The major concerns of the study were to develop and use intervention materials / SIM-
MODs and to investigate their impact in enhancing Grade 8 students’ skills in performing operations
on Rational Algebraic Expressions. The conceptual framework of the study is shown on Figure 1.
The second frame enumerates the process or set of procedures that were to be undertaken
in the course of the study. The process involved: (1) Planning and Conceptualization of the study;
(2) SIM-MOD Development; (3) Evaluation of the SIM-MOD by subject matter experts and students;
and (4)Investigating Impact of SIM-MOD on students’ achievement in Mathematics at the Grade 8
level was the second phase of the study and the last step of the process. The products or outputs
of the study were the developed learning materials (SIM-MODs) and the target competencies:
Improved Skills in Performing Operations on Rational Algebraic Expressions are shown in the last
frame.
The aims of the study were to develop and use learning materials otherwise known as SIM-
MOD, and to investigate the impact of these learning materials on the students’ achievements in
Mathematics at the Grade 8 level. Specifically, this study sought to answer the following questions:

Students’ Academic Achievements in Mathematics at the 8th Grade Level.
The findings of the study are deemed particularly useful to the following users:
Mathematics Teachers. This study can make Mathematics teachers more aware of the
nature and extent of the prevailing problems in teaching Grade 8 Mathematics most particularly
“Performing Operations on Rational Algebraic Expressions”) and the possible remedial measures
to address these concerns.
Students. The students serve as the ultimate beneficiaries of the findings of the study
through the identification of teaching strategies that are appropriate to their characteristics as
learners and enhance their level of achievement in Mathematics.
Parents. The involvement of parents in the study habits of their children can be addressed
by the SIM-MOD. This will help the family bonding and boost morale of the students.
School Administrators. This research can guide the principal, curriculum planners and
other school decision makers through feedbacks on which learning approach should be adopted
by the students in learning a particular task. This also would enable them to make adjustments in
the Mathematics program/curriculum so that it will become more effective and responsive to the
needs of the teachers and make them more effective in teaching Mathematics.
Other Researchers. The study is also expected to serve as a source of useful information
in the conduct of related studies in the field of Mathematics instruction and in other areas of
educational management.

Preparatory Stage
This includes conceptualization and planning of the learning materials developed. Grade 8
students were assessed. Based on the pretest given to them AY 2014-2015, the results revealed
that most of these Grade 8 students or about 58.26% (134 out of 230) of the students belonged to
“Low Mastery Level. Hence, the researcher came up with an idea of developing learning materials
to address this problem. The preparation of materials and other pertinent aspects in the
development of the SIM-MOD were established in this stage.
SIM-MOD Development
This includes the design and development of the learning materials. The following steps
were undertaken in the development of the SIM-MOD: (1) Thinking through a rationale; (2) Deciding
on aims and learning outcomes; (3) Thinking about the content; (4) Exploring learning and teaching
Page 15 of 70
strategies and the appropriate learner support; (5) Focusing on assessment; (6) Considering
learner support ; (7) Planning evaluation strategy.
(1) Developing SIM-MOD Rationale. A need to enhance the skills of 217 Grade 8 students in
“Performing Operations on Rational Expressions” is the primary reason why these packets of
learning materials were developed. The baseline data the researcher obtained every start of every
academic year revealed that indeed the sophomores, now Grade 8 students, find Rational
Expressions as the most difficult topic to deal with in 8th Grade Mathematics under the K to 12
curriculum. Providing interventions for the students was not a first to the researcher. Interventions
were done yearly. The difference is, before, the learning tools provided only for the students were
some exercises taken from the reference book. Now, the learning materials which were being
offered to the students were learning materials developed by the researcher. Plus the assessment
done before was not as comprehensive and scientific as it is today. Findings before were not put
into writing as compared to the present study where every single detail and every action taken by
the researcher were properly documented. The subject matter is very important because for a
Grade 8 student to proceed to the next higher level of Math learning there is need for him to master
first these skills in “Performing Operations on Rational Expressions.” The researcher believes that
it is only through constant practice one can succeed in learning Mathematics. Hence, numerous
hands-on activities provided in these SIM-MODs are highly recommended to every Grade 8
Student.
(2) Deciding on Aims and Learning Outcomes of the SIM-MOD. The aim of the learning
materials indicates the general direction or orientation of the SIM-MOD in terms of its content and
32
its context within the programme. Aims were formulated based on the need to enhance the skills of
the students in “Performing Operations on Rational Expressions.”
Learning outcomes focus on learning rather than teaching and are not about what the
teacher can provide but what the lesson can demonstrate at the end of the course or intervention
program (with SIM-MOD employed).
(3) Thinking about the SIM-MOD content. The topics tackled in this SIM-MODs were as
follows:
SIM-MOD 1. What Are Rational Expressions?
1. Distinguishing between rational numbers and rational expressions
2. Finding all the meaningful replacements of the variable of the denominator of a rational
expression
3. Simplifying rational expressions
SIM-MOD 2. Products and Quotients of Rational Expressions
1. Recalling multiplication and division of rational numbers
2. Recalling factoring polynomials
3. Multiplying rational expressions
4. Dividing rational expressions
SIM-MOD 3. Sums and Differences of Rational Expressions
1. Recalling LCM, addition and subtraction of fractions
2. Recalling how to simplify rational expressions
3. Finding LCD of rational expressions
4. Adding rational expressions having the same denominator
5. Adding rational expressions having the different denominators
6. Subtracting rational expressions having the same denominator
7. Subtracting rational expressions having the different denominators
(4) Exploring learning teaching strategies and the appropriate learner support. According
to Ramsden (1992), even the best designed modules, with very worthwhile defined learning
Page 16 of 70
outcomes, can fail if the teaching strategies employed are inappropriate to encourage and support
the learners towards meeting the desired learning outcomes. With these SIM-MODs, the researcher
has maintained printing of colorful pictures, icons, cover page, etc. to catch students’ interest. It
was a common observation, that when a learning material to be used by a student is thick or
voluminous, he/she loses interests in reading it, so, to avoid such a situation, the learning materials
were subdivided into three packets entitled “What Are Rational Expressions? (SIM-MOD 1);
Quotients and Products of Rational Expressions (SIM-MOD 2); and Sums and Differences of
Rational Expressions (SIM-MOD 3).”
This innovation by the researcher entitled “SIM-MOD (Strategic Intervention Materials and
Module Combined: A Two-in-One Packet of Learning Materials for Enhancing Grade 8 Math
Students’ Skills in Performing Operations on Rational Expressions”, has the following features:
a. What this SIM-MOD is all about. It gives a preview of what students will learn.
b. What you are expected to learn. It presents the focus skills.
c. How to learn from this SIM-MOD. This contains some tips on how to use these learning
materials and mentions the virtues one learner has to possess while answering these packet of
intervention materials.
d. Flow chart in using this SIM-MOD. It includes the step by step procedure in using these
materials. Questions on when to start and when to stop are answered in this section.
e. Pretest. A measure which identifies the weaknesses of a student’s achievements. In this
study, students’ weakness in “Performing Operations on Rational Algebraic Expressions” were
identified and served as basis of remediation type of intervention program.
f. Guide Card. This provides the topic under focus and the skills the learner should master. It
introduces the activities the students have to perform. It also gives a review of the previous lessons
learned.
g. Activity Card. This defines the task/s that the learner should undertake in order to develop
the skill. It provides enough example and work-out solutions. If the learner will have difficulty in
answering the exercises, he can always refer to an example for help.
h. Assessment Card. This helps the learner measure his mastery of the skill upon completion
of the task/s. The result of the assessment also gives the teacher information on the
knowledge/skills the learner failed to understand so that the teacher could revise or improve the
materials to further develop/enhance the identified skills.
i. Enrichment Card. This extends learning providing additional concepts and exercises for
further application of knowledge/skills. This will challenge the learner to think creatively and develop
higher order thinking skills.
j. Reference Card. This provides additional content and emphasizes important facts or details
relevant to the concept in focus. It also provides a list of resources or books the learner may refer
to for further reading.
k. Posttest. It is a measurement of what has been learned by the student in performing
operations on Rational Expressions after undergoing series of intervention program.
l. Answer Key. The answers in the pretest and posttest are listed down in this section and
are found at the last page of these learning materials.
(5) Focusing on assessment. Assessment methods should be in accord with the learning
outcomes of the learning materials and should foster a deep approach to learning. The formative
assessment employed in this SIM-MOD by the researcher was used to inform the respondents as
to how they were progressing. Integral to this process was the feedback that the respondents
received from the researcher to improve their learning. Summative assessment was also used to
Grade 8 students at the end of a SIM-MOD to accredit them at the end of the programme. With
these SIM-MODs, assessment was given serious consideration and reflection and the choice of
assessment methods were all related to the learning outcomes. There was rarely one method of
assessment which satisfied all learning outcomes for a SIM-MOD. It is recommended that in
Page 17 of 70

(6) Considering learner support. From day 1 of the intervention program up to the time it was
ended, the researcher never left his target respondents answering alone these packets of learning
materials. The proponent had provided moral support, motivated the learners, and guided them in
performing tasks provided in the SIM-MOD. Answer sheets were also given for free by the
researcher.
(7) Planning evaluation strategy. Module design and development is an ongoing process.
The kind of evaluation mechanisms employed in this SIM-MOD by the researcher was used to elicit
meaningful information to assist him in reviewing and improving his module. It was based upon
criteria that were cooperatively developed and concerned with gathering information about the
quality and effectiveness of the learning materials. Evaluation is not just a retrospective process,
but can be an integral part of SIM-MOD development, informing one before, during and after the
process. The questionnaire used here by the researcher was the same questionnaire used by an
educationist in the field of mathematics education. The evaluation was based on the following:
a. Design
b. Clarity of directions used;
c. Readability
d. Importance of the content;
e. Appropriateness of activities;
f. Ease of task completion;
g. Opportunities for active learning; and
h. Usefulness in meeting learner’s needs
The developed learning materials have been checked and evaluated by experts before
subjecting it to final testing with the respondents.
The learning materials (SIM-MODs 1-3) have received the following mean ratings from the
experts. Each rating has its corresponding verbal interpretation. (1) Design of the SIM-MOD, 4.67
(Excellent); (2) Clarity of Directions used, 4.00 (Above Average); Readability, 4.67 (Excellent);
Importance of the Content, 4.44 (Above Average); Appropriateness of activities, 4.22 (Above
Average); Ease of task completion, 4.11 (Above Average); Opportunities for active learning, 4.11
(Above Average); and Usefulness of the SIM-MOD in meeting learner’s needs, 4.11 (Above
Average). 4.29 is the overall mean of these intervention materials withan “Above Average” rating
from the experts.
This is actually the second phase of the study, where the developed and evaluated learning
materials were investigated to determine their impact on students’ achievement in Mathematics at
the Grade 8 level. In investigating the SIM-MOD’s impact, the researcher utilized the quasi-
experimental design.
The design involved two groups of students, the control group and the experimental group.
Each group took the pretest before the conduct of the intervention program. After the experimental
phase (intervention) of the study, each group took the posttest. The gain score were compared for
Page 18 of 70
significant difference using the t-test for independent means. This was done to determine whether
the use of SIM-MOD had positive impact on the students’ achievement in Mathematics at 8th Grade
level.
Evaluation of SIM-MOD
After the testing stage, the experimental group, the one that used SIM-MOD, served as the
evaluators of the learning materials. Evaluation of SIM-MOD was based on: (1) design; (2) clarity
of directions used; (3) readability; (4) importance of the content; (5) appropriateness of activities;
(6) ease of the task completion; (7) opportunities for active learning; and (8) usefulness in meeting
the students’ needs.

The students considered for this study were Grade 8 students of Pulong Buhangin National
High School, in Pulong Buhangin, Santa Maria, Bulacan of Section Daisy with 45 students; Section
Gumamela, 43 students; Section Santan, 42 students; and Section Dahlia, 41 students.
The participants mostly from Grade 8 level were grouped into two. One group was assigned
as the experimental group that had used the SIM-MOD while the other group was the control group
that was given traditional work exercises/assignment.
The participants of the study were chosen using the matching technique. The students’
average grade in the first and second grading in Mathematics during the AY 2014-2015 were
calculated and collected. The two groups were divided according to the following means. The top
students were distributed to both the groups. This was also done to the students who have low
averages. This means that both the groups will have almost the same participants. The average of
the grades was calculated using the excel. The results were the basis of distribution. The control
group has 45 students as well as the experimental group.
Instruments
The instruments used in the study were the evaluation instrument for the assessment of the
SIM-MODs, and the achievement test used as pretest/posttest in the study. The SIM-MODs, after
the development stage served as an instrument for the second phase of the study, which was the
investigation of the impact of the developed learning materials/SIM-MODs.
Pretest/Posttest
A 40-item multiple-choice type of test was prepared by the researcher as pretest and
posttest for investigating the impact of SIM-MOD on students’ achievement in Mathematics at the
Grade 8 level. The parallel tests were made after making a table of specification. The constructed
test items were validated by the subject matter experts and were tested to 9-A students of PBNHS
during AY 2014-2015. Minor changes have been made basing on the comments and suggestions
of the subject matter experts. This test was also again given to 9-B students to determine the
reliability of the test.
SIM-MOD
The three sets of learning materials (SIM-MOD numbers 1-3) developed in the first phase of
the study were used as research instrument in investigating the impact of SIM-MOD on students’
achievement in Math at the Grade 8th level. This instrument has undergone a meticulous process
of development and evaluation during the first phase of the study.
Page 19 of 70
Evaluation of the Instrument
The instrument used to evaluate the developed learning materials was a five-point rating
scale adopted from a study by Nivera (2006). The adopted instrument was then revised, mainly
through the researcher’s preferences to suit the needs of the study. The revised questionnaire has
been validated by two faculty members of Pulong Buhangin National High School, one is the Head
Teacher of the Mathematics Department and the other one is the Master Teacher of the same
department who is currently teaching Grade 10 Mathematics.
The evaluation sheet was made up of the following: (1) directions on how the learning
materials will be evaluated; (2) the series of statements as the basis for the evaluation of the SIM-
MOD; (3) section for general comments and suggestions for the improvement of the SIM-MOD; and
(4) the respondent’s name, grade level and section. 42
For the students/ respondents, the five-point Likert Scale was used in the evaluation of SIM-
MOD #’s 1-3. The degree values were determined by the ratings of the respondents and were
interpreted as follows: More Than Adequate (4.51 - 5.00); Adequate (3.51 – 4.50); Partially
Adequate (2.51 – 3.50); Inadequate (1.51 – 2.50); and Somewhat Inadequate (1.00 – 1.50).
For the experts’ evaluation of SIM-MOD #’s 1-3, the five-point Likert Scale was also used.
The degree values were determined by the ratings of the respondents and were interpreted as
follows: Excellent (4.51 – 5.00); Above Average (3.51 – 4.50); Average (2.51 – 3.50); Below
Average (1.51- 2.50); and Needs Improvement (1.00 – 2.50).
Only the students/respondents have evaluated the Delivery of the Program since they were
the only ones who underwent the intervention program on “Rational Algebraic Expressions.”
Before the intervention program was held, the recommending approval of the EPS I
Secondary and Elementary Mathematics, EPS I Research and Evaluation, and the approval of the
Schools Division Superintendent of the Division of Bulacan and of the parents were sought through
communication letters. Scores on the activities in the SIM-MOD of each student in each group
(comprised of 2classes in all) were compiled and attendance was monitored as well. The sessions
lasted for about two rating periods. Included in the program were the follow-up activities in the forms
of enhancement tests, worksheets and collaborative learning facilitated by the researcher with the
help of his student teacher from PUP Santa Maria and high performing students of Grade 8-
Sampaguita. The entire intervention program was monitored by Mrs. Evelyn R. Sicat and Mrs.
Ederlinda P. dela Cruz, Head Teacher of the Mathematics department and School Head of PBNHS,
respectively.
Page 20 of 70
After the intervention period, the participants have evaluated these packets of learning
materials otherwise known as SIM-MOD. And finally, the obtained data from the results of the
intervention program were processed, treated statistically, and interpreted.
Data Analysis
Data collected from the evaluation process were collated, processed, and analyzed
statistically using frequency distribution, mean and standard deviation. These were calculated using
the SPSS. Frequency distribution was used to show the participants’ evaluation of the SIM-MOD in
each of specific indicators in the questionnaire.
On the other hand, the mean was used to analyze the measure of the participants’
assessments Percentage Score Descriptive Equivalent to the
developed 96-100 Mastered learning
materials. The 86-95 Closely Approaching Mastery data were
presented in 66-85 Moving Toward Mastery tabular form
which served 35-65 Average Mastery as the basis
for presenting the analysis
15-34 Low Mastery
and interpretation.
5-14 Very Low Mastery

Equivalence
To determine the mastery level of the participants, the following Mastery Descriptive
Equivalence was used before and after the remediation program.

RESULTS AND DISCUSSIONS
To investigate the impact of the learning materials used for the intervention program on
Rational Algebraic Expressions, a quasi-experimental design was utilized. The mean grade scores
for the 1st and 2nd rating periods were used as baseline data for the comparability of the two groups
(control and experimental). t –test for the independent and dependent means were the statistical
tool used in this phase of the study.

An independent sample t-test was conducted to compare the student scores and mean gain
scores who used the SIM-MOD and those who did not while under the intervention of “Performing
Operations on Rational Algebraic Expressions” for about two rating periods, 3rd and 4th quarters
of AY 2014-2015. The table shows that scores of the control and experimental group on the pretest
do not have significant differences before the SIM-MOD was used by the experimental group (p-
Page 22 of 70
value is 0.855). Upon using the SIM-MOD, a posttest was given to the participants. As seen on the
table, the p-value of 0.000 with a t-value of -11.019 is an indication of the significant difference
between the scores of the students from the control and experimental group. This implies that the
participants who used the SIM-MOD have significant higher scores than those who did not use the
intervention materials. Also, there is significant difference (p-value of 0.000 and t-value of -7.727)
present in the mean gain scores of the participants with regards to their pretest and posttest scores.
This is an indication that the use of SIM-MOD is an effective way of improving the achievement of
the students in their Mathematics subject. The results confirmed findings of Salviejo, Aranes and
Espinosa (2014) that Strategic Intervention Material-Based Instruction has motivating capabilities
that demands attention and creates strong impact to the learners. It also mentioned in their earlier
study that SIM-BI could provide effective communication and proper instruction matched with the
learning needs of the students.
Table 3 presents the participants’ evaluation based on the design, presentation, usefulness,
etc. of the developed learning material. It can be viewed from the table that students find the design,
presentation, usefulness, etc. of SIM-MOD #1 to be “Adequate” (average mean of 4.33).

Most items in the evaluation of SIM-MOD #1 have received an “Adequate” rating from the
participants. Only item 6 (Ease of task Completion) got the lowest mean rating of 3.38. Item 1
(Design of SIM-MOD) has received the highest mean rating of 4.56. The results indicate that
majority of the participants has appreciated the design of SIM-MOD #1 but the completion of the
task contained in it was not that easy for them. 49
Table 4 presents the participants’ evaluation based on the Delivery of the Program or the
Way the Intervention Program with SIM-MOD #1 employed was delivered to the students. It can be
viewed from the table that the students find the Delivery of the Program with SIM-MOD #1 to be

It can be gleaned from the Table 4 that only Item 2 (Time allotted for the program) has
received the lowest mean rating of 3.44 and Item 3 (Support provided for the learners) has received
the highest mean rating of 4.67. The results indicate that majority of the students who underwent
intervention program on “Rational Algebraic Expressions” with the use of SIM-MOD #1 has
appreciated the support provided for them. But what they considered as a problem was the time
allotted for the program. For them, they had a hard time accomplishing tasks in the SIM-MOD due
to the limited time that was given to them in every session per week.

The Delivery of the Program with SIM-MOD #3 has received an “Adequate” rating except
for Item #2, Time allotted for the Program, with the lowest mean rating of 3.40. The support provided
for the learners (Item 3) has received the highest mean rating of 4.38 from the participants. The
perception of the students on the Delivery of the Program with SIM-MOD #3 was just the same as
the Delivery of the Program with the other two SIM-MODs. The support provided by the researcher
was very much appreciated by the participants. But what bothered them in accomplishing the tasks
contained in the intervention material was the time allotted to them in every session per week.
Table 9 presents the summary of the students’ evaluation of the developed SIM-MODs/
learning materials. It can be gleaned from the table that all criteria of the developed learning
materials have received an “Adequate” rating from the participants with an overall mean of 4.31. In
general, the overall mean for the Delivery of the Program was 4.11 with an “Adequate”rating from
the Grade 8 participants.

The Delivery of the Program with SIM-MODs 1-3 has obtained an overall mean of 4.11.
The time allotted for the program got the lowest mean rating of 3.44 and 4.51 was the
highest mean rating received and that was for the support provided for the learners.
The data indicate that the design of SIM-MOD Numbers 1-3 together with the support
provided by the researcher were highly appreciated by majority of the participants. Ease of Task
Completion was a problem to them due to the time allotted to them in every session per week.
These results conformed with the views of Guerra (1996) on the importance of designing our own
classroom materials. That by creating and designing our own materials, we are making a systematic
reflection; we are enriching our own process. The same results also conformed with the statement
made by Salviejo (2014) that a learning material if well design, can also help motivated students
to learn by attracting/marinating their attention. Likewise, materials should be examined for the level
of difficulty. They must be readable and accomplishable if they are to be truly accessible to the
students. Words to be used in the learning material should be suited to the reading comprehension
level of the students that need remediation for a particular topic.
Before the final implementation of the intervention program, the developed learning
materials were validated by the subject matter experts.
The following are the suggestions made by the subject matter experts for the improvement
of the developed learning materials aimed at enhancing Grade 8 students’ skills in “Performing
Operations on Rational Algebraic Expressions”:
Experts
“The color printing must be maintained all throughout the
Layout/Presentation production as well as the paper quality. Having it
produced otherwise will lose its appeals to the students.”
“Revise some of the instruction used in the activity cards
Instructions used (SIM-MOD #2) because it might confuse the learners.”
“Choose the letter of the correct answer (How?).”
“Compared to the first SIM-MOD, some of the
Content discussions (SIM-MOD #2) do not have guide card.”
“Content wise. Very good!”
Page 28 of 70
“The materials follow the scope and sequence of topics
in the K to 12 Mathematics curriculum.
“Have a clear instruction on the activities (SIM-MOD #1).
Activities
Try to name or give titles for the activities.”
“Good paper material.”
“Words to be used should be suited to the reading
comprehension level of the students.”
“Some fonts are obviously different (size) especially pp
5-6 (SIM-MOD #1).”
Others
“It is best to use the same icon for same activity (Just like
what is done for remember icon).”
“Continuous numbering of activities is needed. Example:
Guide Card 1-2-3 etc. Activity Card 1-2-3 etc. (SIM-MOD
#1).”
Summary
There has also been a pattern on the preferences of the participants with regards to the
Delivery of the Intervention Program on “Rational Algebraic Expressions.” Majority of the
participants have appreciated the support provided for them before, during and after the intervention
program in one of the least mastered skills in Grade 8 Mathematics. Most of them have found the
allotted time per session per week not enough for them to accomplish the tasks contained in the
SIM-MODs.
Conclusions
The following conclusions were drawn based on the findings of the study.
1. What are the procedures in the development of the SIM-MOD?
Page 29 of 70
SIM-MOD can be developed guided by an instructional design model such as the ADDIE
(Analysis-Design-Development-Implementation-Evaluation) model. Steps and processes should
be customized to the nature of the learning material to be developed. Specifically, for this study the
intervention material/SIM-MOD was developed through these stages: (1) Preparation; (2) SIM-
MOD Development; and (3) Evaluation.
4. What changes do the experts and students suggest to improve the layout/presentation,
instruction used, content and activities of the SIM-MOD including the delivery of the intervention
program?
SIM-MOD is a valid learning material in teaching Grade 8 Mathematics most specifically
“Performing Operations on Rational Algebraic Expressions.” Results showed that the scores of the
control and experimental groups on the pretest do not have significant differences before the SIM-
MOD was used by the experimental group (p-value is 0.855). Upon using the SIM-MOD, a posttest
was given to the participants. The p-value of 0.000 with a t-value of -11.019 is an indication of the
significant difference between the scores of the participants from the control and experimental
groups. Which led to the conclusions that SIM-MOD has significantly improved the achievements
of the Grade 8 students most particularly in “Performing Operations on Rational Algebraic
Expressions.” This furtherly led to the implications that there was a positive impact of using these
62
intervention materials in developing cognitive skills in the students of Mathematics at the Grade 8
level.
In order to extract information from the students beyond the remediation program, an interview
was conducted. This was done to ensure that some may be captured in order to shed more light
into the results of the research.
Qualitative Findings
When asked about the SIM-MOD experience through interview using open-ended questions,
the students had a lot to say. Even a simple answer and question session would turn into a
discussion as everyone had something to say. They were very excited because of the exposure to
the SIM-MOD.
Ease of Learning
Students gave their feedback. Most of them said that their learning of the rational expressions
made them understand the lessons better. They said the materials helped them in the learning
process. One student said, the SIM-MOD’s presentation made her learning of Mathematics more
Page 30 of 70
interesting. “I learned a lot,” one said comparing her dismal of Math for many years in the
elementary grades.
Perceived Usefulness
When students were asked about how they perceive to be the benefits of using the SIM-MOD
in their learning the rational expressions, they responded that it was a way that helped them to
apply the same techniques in studying other lessons. Some students also indicated that its
usefulness can be used as well even when they go to higher education – when they reach the
college level. The exposure to using the SIM-MOD according to some have given them the needed
self-reliance on doing mathematical activities by themselves. Their self-esteem was boosted as the
SIM-MOD promoted independence in solving mathematical problems as well as establishing 64
opportunities to mingle with their classmates.
Recommendations
The following recommendations were made on the basis of the results obtained from the
analysis of data:
1. Develop and use SIM-MODs in other topics in Grade 8 Mathematics to further validate the
results of the study.
2. Conduct similar studies on the use of SIM-MOD in other discipline to confirm the results of the
study.
3. Use SIM-MOD as a remediation material to enhance the academic achievements of low
performing students in Math and as an enhancement material to furtherly improve the cognitive
skills of average and above average type of students in Math and in other discipline.
4. Encourage administrators, Mathematics supervisors and teachers to make SIM-MOD in all
topics not only the least mastered skills in a given subject area.
5. Teachers shall be provided with more seminars, workshops on the principles of SIM-MOD
construction.
