The Use of Computer Simulated instruction (Csi) of Optics toG10 Student of Bnhs Sy 2017-2018 and its Effect on their Performance

Abstract

INTRODUCTION

Concepts in Physics are considered to be the least understood by high school students since they usually involve solving complex problems alongside memorizing mind-boggling formulas. However, very few innovative teaching strategies were developed in order to address such concern. Thus, this study investigated whether the use of computer simulation instruction was more effective than face-to-face instruction in increasing G10 students of Balayan National High School's performance in topics on optics.

METHODS

The research design employed for this study was quasi-experimental research design of two groups' pre-test, post-test control design. The study lasted for a period of two weeks due to the experimental nature of the research. Topics on optics covered in Grade 10 Science K to 12 Curriculum was provided through a simulation program found in the website https://simbucket.com/lensesandmirrors/ using ray diagrams to the experiment group, whereas the control group had the same instruction through face-to-face teaching methods. A pre-test/post-test composed of twenty multiple choice questions addressing the contents on optics was given to both groups.

RESULTS

Based from the results obtained from the study, a computed t (100) = 1.72 which is less than the t-critical for two-tailed test, t crit=1.98 and p>0.05 was obtained from an independent t-test of the pre-test of both groups. This implies that the two groups selected for the study were homogeneous since there is no difference in their performance. Also, there was a significant difference between the post test of both groups. This is shown by a computed t (100) =7.83 which is greater than the t-critical for two-tailed test, t crit=1.98 and p<0.05.

DISCUSSIONS

By implication, the students who were taught with computer simulation outperformed the students who were exposed to the traditional method of teaching. Thus, the treatment given to the experimental group is effective and responsible for the differences in the performance of students in favorof the treatment class. Students nowadays tend to learn more when using audio-visual teaching strategies which also cater to their short attention span. A lot of researches agreed on the effectiveness of using computer simulation for supporting science teaching and learning. It was therefore recommended that the use of computer simulated instruction (CSI) should be encouraged so as to complement other methods of teaching science in high school students.
