Raising Teaching/Learning Materials to Multimedia
To say from the standpoint of instructors, it is very difficult to present learning materials of good quality, in the current situation.
In the case of blackboard, giving complete expressions or fine pictures is impossible.
This is same for OHP because of the way it is used (simple presentation where attendants' intuitive understanding is expected).
These problems are solved in the way of giving printed matters to each student. But the most appropriate expression for explaining mathematical subjects is the animation.
Because the resolution of the TV monitor is low, expecting the explanatory animated expressions of mathematical subjects is too much.
The combination of a high resolution projector and a big screen allows us to share the contents in the personal computer, and this is a big progress of the situation. But the limitations of the "simultaneous class" remains in the form of "cutting off private conveniences of each learner".
Compared to these, in the case of the Internet online class, we can aim at progressing teaching/learning materials in the form of "multimedia materials" and "personal and interactive learning materials".
