Abstract

This study aims to analyze the need for a discovery learning-based e-module integrated with PhET simulation on reaction rates for grade XI senior high school and to evaluate its feasibility based on BSNP criteria. The research employed the Research & Development (R&D) method with the 4D model (define, design, develop, disseminate), limited to the develop stage. Instruments included interview guides, student needs questionnaires, and validation sheets. The findings revealed that the chemistry learning process at SMAN 14 Medan remains teacher-centered with lecture methods, causing students to be passive and struggle with conceptual understanding. Teaching materials are confined to textbooks, with no e-modules available. The developed e-module fulfilled the BSNP criteria, achieving average validity scores of 90.27% (material aspect) and 88.68% (media aspect), both in the highly valid category. The novelty of this study lies in integrating discovery learning with PhET simulation into an e-module for reaction rate topics, offering an interactive alternative to conventional textbooks. Keywords: e-module; discovery learning; phet simulation; reaction rate
