Abstract
This paper introduces our CAI Teaching Materials to help reading in Japanese. Generally, it is difficult for students to grasp of the relation between topic of discourse and discourse structure, and among of units of discourse structure, both are hierarchically organized. Thus we plan that the students should be aware of understanding the process using a visual information on the computer's display. It is because that computer is suitable to show this process with effect of sound, color and movement. The result of the whole process is memorized in computer, and will then generate it for materials in class activities.
