Development and Evaluation of Instructional Videos in Computer Systems Servicing for Grade 11 Students

This study developed and evaluated an Instructional Video designed to address the low mastery of Grade 11 Computer Systems Servicing learners in assembling and disassembling computer hardware at Bonfal National High School, Bayombong, Nueva Vizcaya, Philippines for School Year 2025 to 2026. Using the ADDIE model, the material was carefully planned, designed, developed, and assessed through a quantitative descriptive approach involving instructional materials experts, and CSS teachers. This material also adopted developmental research approach that involves the systematic design and development of the instructional video. DepEd’s Learning Resources Management and Development System (LRMDS) evaluation rating sheet for non-print materials were used in evaluating the instructional video. Findings revealed that the developed video effectively supported learners’ understanding and skill development, as reflected in positive learner feedback. The material obtained a very satisfactory overall rating (M = 3.83), demonstrating high acceptability in terms of content, instructional, technical, and accuracy components, with content quality receiving the highest evaluation (M = 3.90) followed by accuracy at (M=3.84) and technical quality at (M=3.83), while instructional quality was rated slightly lower (M = 3.76), results still confirmed the video’s relevance in classroom instruction. Mann-Whitney U test with a significance level of 0.05 showed no significant difference between the evaluations of experts and teachers (p = 0.624 > 0.05) across all assessed criteria indicating a shared perception of quality and effectiveness. The study concludes that well designed instructional videos can enhance competency-based learning and serve as reliable teaching tools, particularly in skills-based subjects although continuous improvement in learner engagement strategies is recommended to maximize student engagement, learning outcomes and educational impact.
