This study investigates the application of action research to enhance the development of research methodology knowledge among graduate students. Students, in this study context, were dissatisfied with current courses, leading to knowledge gaps and limited application of research approaches. Through iterative cycles of action research, a book club intervention was implemented. Key findings highlight several critical design elements: selecting engaging textbooks, optimizing group size for interaction, scheduling sessions during breaks, actively facilitating discussion and misconception correction, and integrating technological tools for communication and reflection. Overall, this study underscores the potential of action research as a valuable framework for developing effective educational methodologies, emphasizing the need for thoughtful design in creating supportive learning environments. Future studies should explore innovative teaching approaches that incorporate diverse perspectives to further enrich graduate education.
