<![CDATA[Accelerating science education in the Philippines remains a challenge for many educators. Consistent low performance scores of the Filipino learners based on the Programme for International Student Assessment (PISA) 2022 results call for a need to innovate learning materials and approaches in the field of science education. Hence, this research focuses on the creation of vodcasts enriched with PhET simulations to teach vector concepts in physics and evaluate its effects on the students’ understanding and perception. This is to provide supplementary learning resources to grade 12 science, technology, engineering, and mathematics (STEM) students who face challenges in understanding physics caused by insufficient instructional materials that concretize concepts through visuals. The study is grounded on analysis, design, development, implementation, and evaluation (ADDIE) model for developing vodcasts on vectors as supplementary educational materials. The evaluators rated the vodcasts “satisfactory” yielding a mean rating of 4.15. The implementation resulted in a normalized gain of g=0.68, signifying an average improvement in the understanding of the learners. The main conclusion drawn from this study emphasizes on the effective use of vodcasts to supplement the learning of vectors. In other words, the implementation of well–designed vodcasts can significantly enhance vector instruction and lay the foundation for further improvements in physics and science education.]]>
