Introduction
A. Background of the Study
Education is the multidisciplinary sector of the community. It serves as the
foundation of a better life as others said: “Education is the key to success”. Thus,
much priority must be placed into education. As stated in the 1987 Philippine
Constitution Article II Section 17 that the State shall give priority to education,
science and technology, arts, culture, and sports to foster patriotism and
nationalism, accelerate social progress, and promote total human liberation and
development.
In response to giving priority in education, different strategies have been
tried to cope with this deficiency. But students are still incapable of
understanding the new learning their teachers are trying to convey. According to
a study, it showed that individual differences are the major problems in
education due to different intelligence, abilities, interests and rate of learning
(Vaishnav, 2005). With regards to individual differences, different methodologies
were used to address educational needs, until such time technologies were found
to help resolve the issue.
In the advent of these modern technologies, different courses and programs
were offered in colleges and universities in line with the utilization of these
technologies, one of which is the BSIT Program which is centered on the
evolution and continuous change of technology. The program includes science-
related subjects namely Physics, which is focused on the mechanics, heat,
electricity and magnetism; and Discrete Mathematics, which is focused on
binaries and logic circuit. These two subjects are often the most difficult subjects
for the students since these involve computations and knowledge on analysis.

3. This research wants to determine that if someone finds Physics difficult, he
may also find Discrete Mathematics difficult or vice versa. In short, it seeks to
find out if there is a significant relation between the aforementioned subjects
using the students’ academic performance or grades.
B. Objectives
General Objective
To determine if there is a significant relation between Physics 2 and IT6
based on academic performance of BSIT II Students A.Y. 2012-2013.
Specific Objectives:
1. To get the students grades in both Physics 2 and IT6 subjects
2. To get the mean grades in both Physics 2 and IT6 subjects per set
3. To calculate the Pearson r Correlation Coefficient.
C. Hypothesis
Ho = There is no significant relation between Physics 2 and IT6
Ha = There is a significant relation between Physics 2 and IT6
D. Significance of the Study
The research is significant to the researchers since it serves as their
passage towards passing the subject. This will also help the students and
faculty of this institution to evaluate which part of student-teacher relation
towards the subject needs enhancement. The institution will also benefit from
this research; it will show how effective the teaching strategies of the faculty
are.

4. E. Operational Definition of Terms
IT6 – the subject code for Discrete Mathematics offered in the BSIT Program
Mean Grade – the total average in the subject
Physics 2 – the subject code for Physics: Mechanics and Heat
Set – a group or cluster of BSIT II students

5. Chapter II
Methodology
A. Research Description
The research is descriptive evaluative since student’s academic performance
were used as the main data in the determination of the relation between the
subjects Physics 2 and IT6.
B. Data Gathering
The researchers gathered a copy of record containing all students’ academic
performance or grades from the Program Chairperson of the Institute of
Information Technology. This was done with an approval letter attached at the
end of this research paper.
C. Sampling Method
Since the population of the research subject is more than a hundred (163),
the researchers used the Stratified Sampling Method because the gathered
grades were grouped by sets.
D. Data Instrument
The researchers gathered a record of student’s grades in both Physics 2 and
IT6 from the Program Chairperson of the Institute of Information Technology.
The gathered data are then used to get the mean grades of the students per set
in both Physics2 and IT6.
E. Research Subject
The research subjects are the BSIT-II students of Davao del Norte State
College A.Y. 2012-2013.

6. F. Statistical Test
Pearson r Correlation Coefficient was used by the researchers to interpret the
data since the study aims to determine the linear relationship between the two
variables, Physics 2 and IT6.

B. Computation of Mean Grades
To compute the mean grades for the subjects in each set, this formula was used:
X = ∑x / N

11. In the two computations, same results were found (0.856) which is close to 1;
therefore there is a Positive High Correlation between Physics 2 and IT6, thus
Accept Ha.

12. Chapter IV
Summary, Conclusion, Recommendations
Summary
Physics 2 and IT6 are interrelated with each other, take for example in the
creation of a logic circuit board which is part of the Discrete Mathematics; you must at
least understand some basics of Electricity which is also a big part of Physics, for you to
create a functional one. Since these two subjects are correlated then if one finds
Physics easy, he may also find Discrete Mathematics easy or vice-versa. In a real
scenario, it’s not about passing both subjects but it’s about taking them individually and
differently but seriously because at the end of the day, it matters on how you do things
correctly and wisely.
Conclusion
Based on the results, the researchers conclude that there is a significant relation
between IT6 and Physics 2. It was also found that IT6 can somehow affect Physics or
vice-versa in terms of the academic performances or grades.
Recommendations
The researchers recommend to the future researchers of the same to use other
methodologies and tests to further prove the study. It is also recommended to make
the scope bigger, not just Physics 2 and IT6, but other subjects as applicable as it is.
