The goal of this study is to explore how the ecological context of teacher education influences affect South Korean teacher educators' professional development. The findings reveal that South Korean teacher educators' main concerns about their professional development are related to conducting research. Furthermore, the global influences on South Korean teacher educators' work are also strong. They need to know global trends in education in order to obtain research topics and need to communicate with foreign scholars and educators actively for the purpose of active scholarship. The author recommends on using reflective methods, such as action research or self-study research to facilitate teacher educators.
