Case studies for self-directed learning environment using lecture archives

The main topic addressed in this paper is to support graduate students of diverse backgrounds to take basic courses, before joining a research group to specialize in a particular field. In order to realize effective graduate education, we have developed two types of lecture archives system which systematically store actual lectures in School of Information Science and deliver them as complementary learning materials on the campus network. This paper describes overview of the lecture archives systems in 2005 and 2006, and reports on the case studies of the lecture archives systems. The results of students' questionnaires indicate those effectiveness and some future tasks.
