Development of electric circuit exercise system by e-learning

In this paper, we describe about the development of electric circuit exercise system that has interactiveness and effect of animation by using GUI operation, to make "Movement" of technological model easily underdtood for the students. Althogh we proposed iCass (Interactive Circuits and System Seminar) as a research similar to this paper, we advance the development of the educational support teaching material enhanced more by adding "Problem exercise" and "Learning assessment" insufficient in it.
