Teachers pay more attention to children's habits and routines in their daily life, and pay more attention to their life activities. In every interaction between children and teachers, they constantly develop themselves and construct their own behaviors. At the same time, in the interaction with children, teachers perform the duties of educators and realize the educational function of kindergartens. In these small interactions, teachers may give full play to the educational opportunities involved in them, and may also hurt children's emotions and affect their healthy development. Through the discussion of this study, I hope to arouse teachers' reflection on their behavior, improve the quality of teacher-child interaction, and make children develop better, which is also the practical significance of this study.
