From 2004 to 2017, Korean science teachers have performed the overseas volunteer activity of science experiments in Timor-Leste. The purpose of this study is to analyze the developmental process of this activity. As the theoretical framework, we used coteaching, Cultural Historical Activity Theory (CHAT), and structure theory. The authors analyzed various data through cogenerative dialoguing, which included consecutive analysis and discussion, and confirmed by member check. As a result, the volunteer activity was divided into three periods, and the cases of coteaching in each period were described in three phases: preparation, implementation, and evaluation. This could be described as an increase in the number of interactions among elements in the 3rd generation CHAT model. In addition, the development of the volunteer activity was described as follows: a change of structure by practice, an increase of agency, and a change of practice by the theory of structure. We discuss the importance of an emotional and psychological construct in the continued implementation and development of this volunteer activity.
