講義における学生の質問行動を促進するチャットボットの評価

抄録

The questioning behavior of students in a lecture helps to improve the understanding of not only the questioner him or herself but also other students around him or her. In addition, it can be a very useful feedback for the lecturer to improve the class. However, for many students, questioning behavior causes psychological resistance. In this study, we have developed a chatbot system to encourage students to ask questions. In fiscal year 2021, the system was implemented in an on-demand online class for general education courses in the field of information technology, and its effectiveness in encouraging students to ask questions was verified. The results of the experiment showed that students found it easier to ask questions using the system compared to the conventional question forum. In particular, it was found that checking the questions and answers of other students may encourage them to ask more questions.
