Development and Acceptability of Video Instructional Materials on Research Management Guidelines for Public School Research Coordinators

The MATATAG curriculum emphasizes supporting teachers through professional development and research expansion. This study assessed the acceptability and effectiveness of developed video instructional materials on the Research Management Guideline. Specifically, it evaluated the materials in terms of content, instructional, and technical quality, as rated by Learning Resource Evaluators. A pre-experimental design and descriptive-developmental method were used. The participants included 70 research coordinators from public schools in the Philippines, identified through purposive sampling. Two tools were used: a 15-item RMG Assessment and an Evaluation Tool for Video Instructional Materials. Results showed that the video materials received a “very satisfactory” rating in all evaluated areas. Teachers’ understanding of the RMG significantly improved after using the videos, as shown by a highly significant difference between pretest and posttest scores (p = .000, t = -13.186). The materials aligned well with the Learning Resource Management Section (LRMS) standards regarding content, visuals, and digital effects. The study concludes that video instructional materials are effective supplementary tools for improving teachers' understanding of research processes. It recommends encouraging teacher collaboration in material development and reinforcing validation efforts by LRMS coordinators.
