The purpose of this study is to analyze the dialogue in the instructional reflection using the gaze videos of pre-service teachers in the teaching practice. 4 pre-service teachers (3 females, 1 male) were instructed to wear a eye-tracking device during 4 weeks of teaching practice, and one instructional reflection was carried out using the gaze videos. The collected data were analyzed by the frequency of discourse contents, and analyzed by qualitative categorization. As a result of the study, it was found that discourses such as teaching materials, teaching behavior, student behavior, and other lessons were mainly expressed in the reflection of the gaze videos. And as the number of weeks of class reflection increased, it gradually became more educational. In addition, the gaze videos made it possible to infer the situation, actions, and thoughts of the time, and made it easier to grasp the students expressions and actions. Also, the teacher could recognize the scenes that were not recognized at that time, and they was able to grasp the problem of teaching behavior objectively. And it was possible to recognize and improve gaze treatment and allocation due to the indication of the gaze position.
