Encouraging Critical Thinking Support System: Question Generation and Lecture Slide Recommendations

In recent years, online learning has gained popularity in Japan, increasing opportunities for remote study using lecture slides. However, a common issue in Japanese education is that students tend to not ask questions in class. To address this issue, we propose an online learning support system informed by research on "critical thinking" that facilitates the process of students' questioning and thinking. In this study, we aimed to clarify the relationship between the questions generated by students and the class slides. We did this by analyzing the hierarchical relationship of the keywords that appear in the slides. We also propose a method of recommending appropriate lecture slides for the questions that we hope will encourage students to ask meaningful questions and engage in productive discussions.
