Abstract: This study aimed to develop green screen animation–based learning media for karate refereeing courses. It employed a Research and Development (R&D) approach using the ADDIE model, consisting of Analyze, Design, Develop, Implement, and Evaluate stages. The product developed was jury learning media for karate instruction. The participants included language, media, and material experts, as well as students from the Coaching Study Program. Validation results showed that language experts rated the product at 80%, material experts at 80%, and media experts at 82%, indicating that the media was suitable for further testing. Small-group trials yielded an average score of 80%, while large-group trials reached 90%, categorized as highly suitable. Therefore, the developed green screen–based learning media is considered highly appropriate for use in karate refereeing courses.
