This research aimed to conduct a study to develop an educational innovation called "Online Self-Training Program to Empower Teachers' Learning into Practice: The Case of Flipped Classroom Learning Management," efficiently using the Research and Development (R&D) methodology. This online self-training program consists of two projects: 1) A Teacher Development Project: It includes self-training modules for teacher learning, comprising 10 modules. 2) A Teacher Implementation Project: It involves a self-training module for teachers to use as a practical guideline, consisting of 1 module. The results of the experimental research in the first project revealed that among the experimental group of 16 teachers, their post-test scores met the standardized criteria of 90/90, and they had statistically significantly higher scores compared to their pretest scores. In the second project's experimental research, it was found that the post-test scores of 640 students showed a statistically significant increase in their perception of flipped classroom learning management when compared to their pre-test scores. The research results were consistent with the predefined research hypotheses, indicating that the educational innovation produced by this research has been confirmed to be effective. It can be beneficially applied to teachers and students in schools that are the target population for disseminating the research findings in the future.
