Effectiveness of Strategic Intervention Materials (SIM) on the academic performance of grade 7 students

The study aimed to determine the efficacy of Strategic Intervention Materials (SIM) on the academic performance of Grade 7 students. Employing a quasi-experimental design, the research focused on Grade 7 science students at Flora A. Ylagan High School, utilizing a naturally assembled group as the study subjects. To assess academic achievement, the researcher developed a teacher-made multiple-item test covering wave topics from the third quarter curriculum, aligned with the Department of Education’s learning competencies. The test items were validated by experts and master science teachers to ensure content validity. The academic performance of students was measured through a 50-item pre-test and post-test administered to both the experimental and control groups. The pre-test was conducted before any instructional treatment to establish baseline knowledge and initial equivalence between groups. The same test was given after the intervention to evaluate the impact of the SIM on students’ understanding of wave science concepts. Results indicated that the use of SIM offered a more effective approach to teaching wave concepts compared to traditional methods. However, it was also observed that some students improved their scores through conventional instruction. Findings suggest that instructional approaches should consider students’ analytical skills and learning styles. For diverse learners, employing varied teaching strategies is essential. Student-centered approaches are particularly recommended as they provide opportunities for learners to discover their talents and skills while enhancing self-confidence.
