The study was conceptualized to address the need for the development and validation of an intervention material for least learned competencies in selected topics in Physics 10. Moreover, it is also focused on understanding how the intervention material will help improve the learners? mastery of concepts and the perceived effectiveness of the intervention material to the learners. The research design used in this study is the Quasi-Experimental method of research. The present study concerns the development and implementation of an intervention material for least learned competencies in selected topics in Physics 10. Thus, a quasi-experiment was used. The respondents of the study were Grade 10 learners in Magdalena Integrated National High School. The area of investigation was limited to four (4) areas of investigation: 1) what is the level of performance of the Grade 10 students in Physics? 2) what is the level of acceptability and validity of the intervention material as rated by teachers and students? 3) if there is a significant difference between the student?s performance in terms of pretest and posttest? and 4) if there is a significant relationship between the level of acceptability as rated by the teachers and students and the mean scores of the students. The findings of the study were the difference in the learners? academic performance it was noted that there was a substantial increase in the students? performance. Shown by a mean difference of 11.13, it was found that there is a significant difference in the students? performance, based on their pre-test and post-test scores (t=-27.518, p=0.00). In addition, the difference in the level of acceptability as rated by the two groups of respondents, both the students and the teachers assessed the acceptability of the intervention material in terms of adaptability as highly adaptable. No mean difference was noted in their ratings about its adaptability. Therefore, there is no significant difference in ratings given by the students and the teachers with regard to the adaptability of the supplemental material (t=0.309, p=0.764). It was concluded that the adaptability, content, and usefulness of the intervention materials were acceptable to the teachers and students as interventions for the least learned competencies in selected topics in Physics 10 and the students? performance pretest and post-test were evident that the result of the posttest increased thus, the intervention materials were effective to the least learned competencies, they increased their academic performance after they use the intervention learning materials.
