This research aimed to develop learning by e-learning system in Mahamakut Buddhist University, Mahavajiralongkorn Rajaviyalaya Campus. The method used in this study was Participatory Action Research that consisted of two cycles of planning, practice, observation, and reflection during two semesters in the academic year 2020. Twenty-one teachers and forty students were voluntarily involved with the desired development and participated in this research. The three expectations from the development outcomes were: 1) the improvement under the identified indicators, 2) the researcher, the research participants, and the campus learned from practice, and 3) knowledge gained from practice will benefit continuous improvement in the future. The research findings illustrated three following aspects. Firstly, in both Cycles 1 and 2, the means of post-practice evaluations were higher than the means of pre-practice evaluations in the following programs; e-learning system development, meditation practice learning development, and teacher's skill enhancement for creating online media. Secondly, the researcher, the research participants, and the campus learned the following common aspects: an awareness of the importance of participation, being an all-the-time learner, and transcribing lessons from practice which was previously often neglected. Finally, the knowledge gained correlates with Kurt Lewin's Force-Field Analysis which consists of the following concepts: 1) Expected change, 2) Driving factors for change, 3) Resistance to change and 4) Overcoming resistance. Each component defines a set of thoughts and beliefs that Mahamakut Buddhist University, Mahavajiralongkorn Rajaviyalaya Campus, will implement as a basis for reviewing and strengthening an additional set of ideas and beliefs.
