This study aims to explore the problems and ways to improvement of the class "Sports Ethics and Group Dynamics" after the concept of OMAK (Observing Merits and Appreciating Kindness) was intergraded into the class. It applies the approach of action research by four circulation steps: planning, acting, observing, and reflecting (PAOR). Through the questionnaire designed by the authors, students' learning responses are collected and analyzed. The findings of this study are as follows: first, over 70 percent of the students recognize the course objectives, course contents, the ways of instruction and assessments, and agree with maintaining the design of the class as a whole. Second, although 20 percent of the students feel pressure for the class activities, almost 90 percent of the students agree keeping the practice of oral presentations. Third, for the satisfaction survey of individual units, more than 70 percent of the students think that almost every unit (expect for the unit of "terminology") of the class are worthy and should be kept. The researchers realize profoundly that the key to success of the class is the instructor's practice and realization of the concepts and content of the curriculum first, and through sharing of his/her experience, failure or success, s/he can deliver the spirit of the class.
