This study was to understand about teachers' self-supervision experience through their own teaching analysis in a child-care center. The participants of this study were eight teachers working at D private child care center. Five types of data were collected; classroom video recordings, lesson plans, teacher self-evaluations and journals, and four times individual in-depth interviews. Qualitative analysis was done on the collected data. The results of this study were as follows:
First, the teachers had no idea of what self-supervision is, and thinking that they are evaluated through self-supervision. By having experienced self- supervision, they came to realize that self-supervision is an evaluation on their own performance, which helps improve their teaching skills. Second, the teachers gradually became confident, comfortable and satisfied with self-supervision. Third, the teachers focused on their own discourse, ways of talking and tone, children's interests and reactions, and lesson plan and introduction-unfolding- wrapping up of a teaching process while self-supervision. Finally, self-supervision helped the teachers do away with stereotypes, be flexible in responding to children, and acquire new knowledge through problem solving. Furthermore, they attempted to collaborate with their peers by participating in other class or sharing video recordings in self-supervision.
