Abstract
This study aims to develop and evaluate an interactive digital simulation-based training module for the National Science Olympiad (OSN) in junior high school physics. The module was developed using the Research and Development (R&D) method following the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). It was designed as a web-based resource using Canva and integrated with simulations from GeoGebra and PhET to present physics concepts in a dynamic and interactive way. Validation by three experts from the Institut Teknologi Bandung resulted in an average score of 3,2 for content validity and 3,0 for media validity, both categorized as ^very valid^. The module was then tested on twelve junior high school students from Serang Regency who were prospective OSN participants. The training showed moderate effectiveness, with an average N-gain score of 0.37. Feedback from the participants and a supervising teacher yielded practicality scores of 3,5 and 3,8, respectively, indicating the module is ^very practical^.Based on these results, the module is considered effective, valid, and highly practical, making it suitable as a supporting tool for OSN science training at the junior high school level.
