The Research and development (R&D) methodology was employed in this research to create an educational innovation, called "Online Self-Training Program for Development for Teachers' Learning to Enhance Prosocial Behavior for Students", which was effective according to the specified criteria. This online self-training program consisted of two projects: 1) the development project for teachers' learning, comprising six self-training modules for teacher development, and 2) the project for teachers applying learning outcomes to learner development, consisting of a self-training module used as a guideline for teachers. The results of the experimental research showed that the developed educational innovation was effective according to the research hypotheses. The results of the experimental research in the first project showed that the post-test scores of 13 teachers met the standard criteria of 90/90 and were significantly higher than their pre-test scores. The results of the experimental research in the second project also revealed that the post-test scores of 55 students who were the target group of the development were significantly higher than the pre-test scores. This indicates that the educational innovation, called "Online Self-Training Program for Development for Teachers' Learning to Enhance Prosocial Behavior for Students" has been confirmed in quality. Therefore, it can be disseminated and used to benefit both teachers and students who are the target population on a large scale.
