This study attempted to explore 15 Korean elementary pre-service teachers' views of inquiry teaching. During a science teaching methods course, pre-service teachers implemented a peer teaching lesson, had a group discussion to reflect on five teacher educators' comments on their first peer teaching practice, and revised and re-taught the lesson as a second peer teaching practice. The Results indicate that pre-service teachers changed their views of inquiry teaching from following the process of inquiry or a completely unstructured discovery approach to facilitating students' inquiry learning with instructional guidance. The importance of reflective group discussion and re-teaching a lesson is discussed.
