The Efficacy of the Strategic Intervention Materials (SIM) to the Achievement in Physics of a Selected Group of Public School Students in Las Nieves, Agusan del Norte

Abstract

The main purpose of the study was to determine the efficacy of Strategic Intervention Materials (SIM) to the achievement in Physics of a selected group of fourth year public school students in Mat-i, Las Nieves, Agusan del Norte. It is a pretest-posttest quasi-experimental method that aimed to determine the least-learned competence and performance of the fourth-year pupils in Physics before and after utilization of the SIM. The study used the ADDIE model which consisted the five (5) phases namely: Analysis, Design, Development, Implementation and Evaluation. The SIMs that were utilized by the selected group of students followed careful planning and formulation and were validated and assessed by credible evaluators and students themselves. The substantial contents of the
said materials were based on least-learned or least-mastered concepts or areas among the suggested ten (10) core topics in Physics. Results of the study revealed that the utilization of the SIMs were effective in improving the least-learned competence of the learners in Physics as evidenced by its significant increase in their posttest scores. Moreover, the increase in the performance in physics is highly determined by the introduction of SIM in the class and not by the remediation in mathematics.
