Viewpoint of Class Subject and Classroom Space on Face-to-face Course and Online Course

COVID-19 made the performance of face-to-face course difficult and enforced that online course can take an important role in place of the face-to-face course. The online course is not necessarily a new type of course. In the universities, MOOC (Massive Open Online Course), and Moodle (learning management system), etc. have been already in service. In the school education, it is not sure that all lectures can be performed by the online course without any problems. The environmental improvement, the lecture preparation, etc. are not only barriers, but also the ages and levels of pupils, the kinds of schools, the subjects and contents of lectures, etc. are not always unified in the curriculum criterion: this fact indicates that the same procedure, the same framework and so on cannot be applicable uniformly. In this paper, we analyze the features of face-to-face course with respect to the goal and policy of school education, and then discuss the adaptability in the online course. In this case, we compare the video conference system ZOOM, the groupware system Teams with “together” mode, and our round-table-based interaction interface, and make the functionality and mechanism clear as the online course support system with interaction interface. Our round-table-based interaction interface was developed experimentally by our research project team about 12 years ago.
