Development and Validation of Virtual Supplementary Learning Material (VSLM) in Science for Junior High School

This research developed and validated a virtual supplementary learning material (VSLM) focusing on the least mastered topics in science based on the Most Essential Learning Competencies (MELCs): for Grade 7: MELC 3 & 4; Grade 8: MELC 3 & 6; Grade 9: MELC 1 & 3; and Grade 10: MELC 3 & 4. This study aimed to innovate a learning material to enrich the new normal education system. The data were collected using quantitative and qualitative approaches. The researcher used a checklist type of questionnaire and interview sheet form. The acceptance was rated based on its high validity with specific aspects: learning objectives, content, adequacy, presentation, and usefulness. There were 2 groups of respondents for the study. The first group was composed of 8 master teachers and 10 science teachers who validated the learning material based on its aspects. The second group was composed of 156 least performing Junior High School students who utilized the developed learning material. Findings revealed that the student’s performance increased based on the Pre-test and Post-test results after the utilization of the developed VSLM. The results showed that the utilization of the developed VSLM is significant for an effective increase in the level of performance in terms of conceptual understanding, self-efficacy, and motivation of the least performing Junior High School students. As such, it can also be used as supplementary learning material to promote science literacy by the schools since it is a virtual type of material that students can adapt and relate with.
