Abstract:
This study aimed to investigate the effectiveness of Strategic Intervention Materials (SIMs) in improving Grade 7 Science learning outcomes, particularly in chemistry. A quasi-experimental design was employed with two existing sections of 40 students each, assigned as the control and experimental groups. The developed SIMs were aligned with the least-learned competencies and quality assured by school learning resource evaluators in terms of curriculum alignment, reading materials content, printing content, illustration content, design and layout, paper and binding, size and weight, accuracy and recency of information, and contextualization. A 30-item pre-test and post-test were administered to determine the mean scores of both groups. Data were analyzed using a paired-samples t-test to compare mean scores and an Analysis of Variance (ANOVA) to test the significant differences between the pre-test scores for baseline comparison and the post-test scores for evaluating SIM effectiveness. Findings showed that the control and experimental groups had comparable pre-test scores. After using the SIMs, the experimental group obtained significantly higher post-test mean scores than the control group, indicating that SIMs enhanced students’ understanding of the concepts. The validated SIMs received very high ratings in all quality indicators, confirming their quality and relevance. It was concluded that SIMs are effective intervention materials for helping learners master science concepts. It is recommended that DepEd and schools lead the institutionalization of SIM use and support teachers in developing instructional materials, and that future research explore the long-term effects of SIMs in other learning areas and grade levels.
