This study aimed to synthesize and evaluate a STEAM Learning Ecosystem on Gamification System to Promote Innovators. The research was conducted in three phases: (1) synthesis, (2) development of the learning ecosystem, and (3) expert evaluation. The resulting ecosystem comprises three main elements: (1) STEAM Learning Ecosystem (Instructor, Learner, Investigate, Discover, Create, and Reflect), (2) Gamification Process (Goals, Rules, Reinforcement, Time Feedback, Competition/Cooperation, and Feedback), and (3) Innovation Skills (Creativity, Imagination, Inventiveness, Idea Generation, Novel Approaches and Problem-Solving). Nine experts evaluated the ecosystem's suitability using a questionnaire. The results showed the highest level of suitability (mean±SD=4.60±0.49) across five aspects: objectives, design principles, elements, learning process, and ease of understanding. This research contributes to STEAM education by providing a comprehensive framework integrating gamification strategies to foster innovation skills. The proposed ecosystem offers a structured approach for educators to design engaging and effective STEAM learning experiences that promote innovative thinking. Further research could explore this ecosystem's practical implementation and impact in various educational settings.
