The Impact of Multimedia-Facilitated Instruction on the Academic Performance of Grade 8 Students in Science of Trece Martires City National High School

Abstract

INTRODUCTION

This action research determined the impact of multimedia-facilitated instruction in raising the academic performance in Science of grade 8 students of Trece Martires City National High School. Specifically, the significant difference in the level of academic performance of the two groups of student-respondents prior to the experiment based on their pre-test scores was noted. Likewise, the difference in the level of academic performance in science of the student-respondents in the control and experimental group after the use of multimedia-facilitated instruction was investigated.

METHODS

The study involved the two homogeneous Grade 8 classes at Trece Martires City NationalHigh School. Both classes were pre-tested to determine the students' level of academic performance in Science prior to the experiment. After this, the control group received the traditional approach in teaching Grade 8 Science while the experimental group was taught using multimedia-facilitated instruction. Both the control group and the experimental group were post-tested to check if there was improvement in their academic performance. The data was then prepared for analysis.

RESULTS

Results showed that both groups scored low in the pre-test with a mean of 4.53 and 4.88, respectively while both improved their scores in the post-test with a mean of 8.21 and 9.25, respectively. Moreover, the computed t-ratio of -0.1295 is lesser than the tabular value (1.960) at 0.05 level of significance which means that there is no significant difference in the pretest scores of the class groups. This means that both groups are on the same level prior to the experiment. Meanwhile, the computed t-ratio of 2.1295 is higher than the tabular value (1.960) at0.05 level of significance which means that the posttest scores of the groups significantly differ resulting in higher scores for the experimental group.

DISCUSSIONS

Grade 8 students in the experimental group outperformed those in the control group after the use of multimedia-facilitated instruction in Science. Therefore, the intervention multimedia-facilitated instruction is a viable strategy in teaching Grade 8 Science and is recommended to be adopted in the future.
