意図的にグループを形成する授業支援システムの開発

抄録

The GPA averages in large classes are lower than those in small classes. This tendency is because large classes must be one-way teaching from teachers to students. For this reason, a system has been developed to realize active learning through group learning, even in large classes, since FY 2018. So far, a proof-of-concept of a group formation system has been conducted to evaluate group composition using a group discussion visualization system, support for LTI 1.3 in the LTI tool, and implementation of group formation using Word2Vec. As a result, initial research objectives were achieved by FY2021. Therefore, this fiscal year is positioned as the final year of our research, and the implementation of a system based on the results of the research to date is conducted. First, a summary of the research results to date and the development of the system reflecting these results are described. The research question is set - “How to implement the research results?” As a result, a system with REST architecture was developed as an LTI tool linked with an LMS and formed groups based on a similarity between keywords using Word2Vec. The significance of using this system in classes and developing a system for research purposes are discussed. For the former, the system’s significance is that group discussions can be realized in large classes without teachers’ and teaching assistants’ administrative work. For the latter, we proposed using the system in the research community, in classes as an OER (Open Educational Resources), and as a reference for companies.
