In Gifu National College of Technology, we have two classes, named as Fundamentals of Digital Systems and Applications of Digital Systems. These two classes have three features. First of all, they are conducted as e-learning. Because some students have little basic knowledge of digital systems, it is mandatory to attend some lectures. In addition, these classes have five different types of attendance. These types are students of Advanced Course, non-degree students, students from other colleges, adults of the Gifu Network University Consortium and students of Acquisition Program of Design Skills for Digital Systems, respectively. Furthermore, we rend practice boards. From some results of questionnaire survey, it was appeared that the practice boards were very useful for these classes.
