This educational design research aimed to develop and evaluate a video-assisted learning module (VALM) to enhance learners’ mathematics proficiency and improve teachers’ instructional efficiency. The study, anchored on the ADDIE Model, gathered data from year 11 and 12 pupils and five experts. Analysis revealed least-learned competencies in general mathematics, particularly exponential, logarithmic and inverse functions. The VALM comprised a learning module with supplementary video content. The module included a cover page, preface, objectives, study and practice guides, assessment, references, solution boxes, graphing pages and an answer key. The video featured a title, disclaimer, objectives, step-by-step solutions and references. Both learners and experts rated the materials highly acceptable regarding learning objectives, content, organisation, presentation, format, design, activities, and assessment. The VALM was helpful, easy to understand, enjoyable, convenient and mobile. Results suggest that video-assisted learning modules are conducive to enhancing mathematics proficiency and serve as practical supplementary instructional tools across various teaching-learning scenarios in general mathematics.
