This research aims to explore the motivations driving faculty engagement in extracurricular activities at universities and to investigate the patterns of such involvement. Qualitative study was conducted, focusing on five professors who repeatedly participated in the Convergence Project, an extracurricular program at a university in South Korea. The findings reveal that motivations for faculty engagement include positive responses to external requests, a sense of responsibility as an educator, and a passion for the field of research. Furthermore, faculty engagement is characterized by their behaviors, emotional responses, and cognitive processes. Specifically, participants engaged in the program by assisting students, experiencing joy, and feeling a sense of accomplishment. They also prioritized understanding, analyzing, and continuous problem-solving efforts. This study demonstrates that faculty engagement is a multidimensional phenomenon involving a variety of aspects, such as time investment, physical activities, emotional responses, and cognitive engagement. Additionally, it emphasizes that participation in extracurricular programs represents a growth experience for faculty members. Finally, recommendations are provided for promoting faculty engagement in extracurricular programs at universities.
