Many medical schools provide curricular or extra-curricular courses focused on service activities for social responsibility. Research on service learning varies from theory to teaching model, but research on service learning in medical education is difficult to find. Therefore, this study's aim was to develop a model that combines a medical education curriculum with service activities in Korea. A design based research method was used to develop a service learning model in medical education in Korea by; analysing problems in educational settings (2014-2017), reviewing literature, and going through a total of three formative cycles. As a result of applying the first Service Learning Model in Korea Medical Education (K-SL-ME), which was developed through a literature review, to the school setting in three cycles and revising it, we developed a final Service Learning Model in Korea Medical Education, with stages of preparation, orientation, implementation, reflection, celebration, and evaluation. Analysis of students' results over the three years showed that the feelings of reward, interest, and satisfaction levels increased progressively. In particular, the students showed a stronger sense of reward, interest and satisfaction in the final K-SL-ME model applied in 2017 than in the first K-SL-ME model applied in 2014. This study is significant in that it outlines the concepts, need for, and teaching model of service learning necessary for the delivery of service-related programmes in medical education in Korea.
