Abstract
In this study, we discuss the design and development of prototype interactive educational materials for a class of mathematical information science in university. These materials are mainly assumed to be used for learning by oneself. In addition, we assume that (1) these materials are used on several types of devices, (2) complex mathematical formula can be handled, and (3) the developing tools are as usual as possible. We have actually developed the prototype materials and used them in the class. The effectiveness of them and the contents in the development are discussed.
