The purpose of this research was to employ the Research and Development (R&D) methodology to produce an educational innovation, called "Online Self-Training Program for Empowering Teachers' Learning to Develop Students' Design Thinking Skills", expected to be widely used among the schools that are the target population in disseminating the research results. This online self-training program consisted of two projects: (1) the development project for teachers' learning, consisting of seven self-training modules for teachers' learning, and (2) the project for teachers using learning outcomes for student development, consisting of a self-training module used as teachers' practice guideline. The experimental results of the first project revealed that the post-test scores of 16 teachers met the standard criteria of 90/90 and their post-test scores were significantly higher than the pre-test scores. The experimental results of the second project pointed out that the post-test scores of 300 students were significantly higher than their pre-test scores. The research results were, therefore, by the established research hypotheses, indicating that the effectiveness of the educational innovation was confirmed. As a result, it can be used to benefit teachers and students in schools that are the target population for disseminating research results.
