Computer Graphics as Teaching Materials

神奈川県茅ヶ崎市 The development of technology has allowed the computer to express more than numerical infomation. In the near future, the computer is going to play an important role as an expressive tool for users to present infomation. The capability resulting from the combination of this expressive ability and the interaction of computer and user is called multi-media or media integration . The computer is now changing its role from just a tool for reduction of labor to a medium for human communication. In this paper, first, the general situation of computer graphics (CG) and their possibility in education are described. From the educational viewpoint, it is necessary to pursue the ways to cultivate students who are able to participate in our highly visual-oriented society. As a specific example, the course of CG at Bunkyo University is discussed. In this discussion, an educational CG system is introduced. It is implemented using computer network technology. This system gives the students an opportunity to get experience of making CG with simple operations. As an evaluation of CG course, the results of a student opinion survey are analyzed by way of SS (Semantic Structure) analysis. The SS analysis provides ideas for considering various factors behind the responses of the students by revealing the hierarchical structure of the questions. Finally, the efficient use of CG technology in education is discussed. In this discussion, the use of CG in general education is not restricted in computer scientific subjects. After considering some technological restrictions which come from existing computer capability, in order to pursue the ideal use of CG in education, the authors forecast the future of CG technology, especially CG animation
