Abstract

Persistent low performance in Science among Filipino learners, as evidenced by international assessments such as PISA and TIMSS, highlights a critical gap in the development of scientific literacy, particularly in understanding complex concepts in Earth and Life Science. This issue is further heightened by limited use of engaging, differentiated, and competency-based instructional materials that address least mastered skills. To address this gap, this action research investigated the effectiveness of a Gamified Strategic Intervention Material using a Competency-Based Instruction (SIM CBI) approach in improving the academic performance of Grade 11 learners. Anchored in Differentiated Instruction, Game-Based Learning, and Constructivist Learning theories, the study utilized a mixed methods design in which meta-synthesis and meta-analysis intersection was analyzed to elicit its meta-inference relationship. A meta-analysis procedure (pre-test and post-test) identified least mastered competencies, followed by the implementation of gamified intervention materials tailored to these learning needs. Results showed a significant improvement in learners’ performance, with mean scores increasing from 4.286 to 8.571, supported by a statistically significant p-value (
