This research aimed to investigate by utilizing the Research and Development (R&D) methodology, to yield innovative educational outcomes. The focus was on efficiently deriving educational innovations from experimental research that had been conducted in field settings. The intended applicability of the research findings was directed towards benefiting schools that serve as the target population, and thereby, facilitating the widespread dissemination of the research outcomes. This educational innovation took the form of an online self-training program, which was comprised of two distinct projects. Firstly, there was the Teacher Development Project, which encompassed seven modules designed for the professional growth and learning of educators. Secondly, the Teacher-Led Learning Enhancement Project consisted of modules that were intended to be practically applied by teachers in facilitating the translation of the acquired knowledge into student development, with a single module dedicated to this aspect. The experimental research results from the first project revealed that those teachers belonging to the experimental group (consisting of 13 individuals) had attained post-test scores by the 90/90 standard. Furthermore, the scores exhibited statistical significance, given that these scores had been higher than the scores obtained from the pre-test. In addition, the experimental research findings from the second project revealed that the target group of students, who benefited from the developmental intervention (210 individuals), had exhibited post-test scores that had been significantly higher than their respective pre-test scores. This factor demonstrated that the utilization of the Research and Development (R&D) methodology in this study had resulted in the development of an educational innovation termed "Online Self-Training Program to Enhance Teacher Learning for Student Development: The Case of Collaborative Leadership Skills." The effectiveness of this innovation aligned with the research hypotheses, and thereby demonstrated that the program could be beneficially applied to teachers and students in those schools that serve as the target population. Consequently, the research outcomes can be disseminated for future use and implementation.
