It is to visualize it as converted data and try to study lesson improvement based on it. The text data of 268 first-year junior high school students from A junior high school and B junior high school were analyzed. In the frequency of occurrence analysis, the frequency of appearance of similar words and the frequency of appearance of similar words were found in both A and B junior high schools. In the words used during the lecture, "invite", "hazardous substance", "smoke", "lung", "emphysema", and "money" appeared. "Surprised", "know", "thank you", etc. appeared in the words of evaluation for the lesson. When looking at the relationships between men and women by school or by class, there was a tendency for the number of frequent words to appear differently depending on the school, and for words that characterize gender to appear. Looking at the co-occurrence network, it was possible to visualize the overall picture of the impressions of the lesson, and the lesson content that left an impression, the evaluation of the lesson, and the quantitative data of the content that left an impression and the evaluation appeared. By examining the lessons based on these visualized data, it was possible to prevent the subjective examination of the students as much as possible. Then, there was a remark that led to reminding the students how they thought about the information of the incoming lesson and became a new recognition. In the future, it will be a challenge to consider the relationship between each teacher's behavior, how to present teaching materials, and thoughts on smoking prevention lessons, and the lesson content that left an impression on the students.},
