This research is a Research and Development (R&D) study aimed at developing educational innovation entitled "Online Self-Training Program to Empower Teachers' Learning into Action to Enhance Active Learning in the Classroom", and implemented in schools. The online self-training program consists of 2 projects (1) a Development project for teacher learning which includes 7 self-training modules, and (2) the implementation of an online self-training program project which includes 1 self-training module to be used as a teaching guideline. The research consists of 4 steps. The final step was an experimental study. The results of the first project found that 12 participating teachers achieved post-test scores that met the standard of 90/90. The average post-test score was statistically significantly higher than the average pre-test score. Additionally, results from the second project found that, according to students' perception scores, the average post-test score was statistically significantly higher than the average pre-test score among 500 students. The results confirm that the "Online Self-Training Program to Empower Teachers' Learning into Action to Enhance Active Learning in the Classroom," is an effective educational innovation for teachers. Therefore, it can be disseminated for the benefit of teachers in schools on a broader scale in the future.
