Evaluating the Effectiveness of the Strategic Intervention Material in Improving the Academic Performance in Science among Grade 9 Students of Dacanlao Gregorio Agoncillo National High School

Abstract

INTRODUCTION

It has been reported in the National Achievement test results last 2011 by Department of Education, that amongst all other discourse, Science has consistently given lower rates. Science teachers need aids to transfer this knowledge to students on their aim to make them more scientifically literate. Strategic Intervention Material is a teaching aid that can be introduced to any teaching methods in order to stimulate the activity of the students inside and outside the classroom. The researcher has delved to study the effectiveness of the developed SIM in the academic performance of Grade 9 students in science.

METHODS

This study was composed of respondents from Grade 9 Science teachers and students who are currently enrolled in Dacanlao GANHS. Test papers and raw scores of students were analyzed to identify the competency that was least mastered.In this manner, the sample respondents of this study covered sixty students divided into two; the experimental and controlled group. The developed SIM was evaluated and validated through questionnaires by eighteen science teachers. Data were tallied and interpreted with the use of weighted mean and t-test.

RESULTS

Both the teachers and students found out that the SIM was effective in improving the academic performance of the students as shown by weighted mean of 2.33. A mean score of 32.85% and 94.67% level proficiency indicated that the remedial strategy of incorporating Intervention material in the experimental group was more effective than the controlled group. It was also proven by the achievement level of 4.30 for the controlled group and 9.27 for the experimental group that the intervention material enhances the academic performance of the students. With the weighted mean of 2.33, students believed that the Intervention Material was strongly effective in catching their interest. Moreover, teachers' responses agreed with students' responses as shown by the weighted mean of 2.33.

DISCUSSIONS

In the light of the findings, the researchers found out that students performed better based on the results of their posttest and thus showed significant effects ontheir academic performance in Science. No significant difference existed between the responses of students and teachers on the effectiveness of the SIM as to its title, objectives, activities, and assessment tools used. Upon analyzing the findings and theresult of the study, the researchers suggested to utilize ICT to enhance and further develop the material.
