Development of Intertextual Learning Videos on the Concept of Exothermic and Endothermic Processes

Learning the concepts of exothermic and endothermic processes remains challenging due to their abstract nature and the difficulty of connecting macroscopic, submicroscopic, and symbolic representations. This study aims to develop an intertextual-based learning video on exothermic and endothermic processes that is feasible in terms of content, pedagogy, and media aspects. The study used a Research and Development (R&D) approach based on the Borg and Gall model, limited to five stages: reseacrh and informating collecting, planning, develop preliminary form of product, preliminary field testing (review), and main product revision. Validation was done by experts in content, pedagogy, and media experts using assessment instruments based on the evaluated aspects. The review results indicate that the developed video meets the eligibility criteria after revisions based on expert feedback. The video integrates macroscopic, submicroscopic, and symbolic representations through the Predict–Observe–Explain (POE) model, supported by learning and multimedia principles. Therefore, the intertextual-based learning video is suitable as a learning medium to support students’ conceptual understanding of exothermic and endothermic processes.
