Objectives The purpose of this study was to examine the after-school sports activity experiences of elementary school students in a small-scale setting and explore the educational implications of these experiences. Methods To achieve this, data were collected from 6 students in grades 3 to 6 who participated in after-school sports activities at a small-scale elementary school during the first semester from March to July 2023. Data col-lection involved participant observation, in-depth interviews, and document analysis. The data were analyzed us-ing iterative comparative analysis, and the credibility of the research was ensured through triangulation, peer dis-cussions, and confirmation from research participants. Results The students' experience in small-scale elementary school after-school sports activities is described as “Reviving the Spark of Small-Scale School Physical Education.” Due to insufficient preparation in regular physical education classes by homeroom teachers, students had lost interest. In response, after-school sports activities served the purpose of fulfilling the lack of physical activity, bridging care gaps, and providing enjoyable leisure time, positively impacting students' holistic development and self-realization. The educational significance is framed as “Illuminating the Torch of Public Education.” The collaborative format of after-school sports activities facilitated interaction between grade levels, fostering exchange among students. It provided opportunities for mutual learning and motivation between juniors and seniors. Additionally, it contributed to reducing private educa-tion expenses, restoring trust in public education, and offering a broad range of sports experiences. Conclusions The after-school sports activities in small-scale elementary schools provide students with oppor-tunities for growth and development on various levels. Therefore, the activation of physical education activities in small-scale elementary schools is necessary.
