Due to the recent development of network technology, it becomes more significant to develop systems to support various human activities on distributed systems. We have been developing one of the important applications of such systems; a distance education system called VIEW Classroom. Conventional distance education systems use video image of teachers and selected students when required. From initial stage this system has taken a stand on non-video base (although video function can be utilized) and tried to use database technology extensively in order io assist the whole range of teaching and learning activities. Typical features of VIEW Classroom are as follows: (1) Asynchronous interaction support: Many of conventional education systems are based on synchronous interaction, though asynchronous interaction can be also realized by object-oriented database functions. (2) Database views: Teacher and student can see different teaching materials if required. For example, teacher can see detailed explanations and students can organize their own textbooks by combining reference books and notebooks. (3) Question-Answer database: Since the number of students in a distance education system can be hundreds, we need an efficient way to answer questions issued by students. Previously asked questions are stored together with corresponding answers in Question-Answer databases for such a purpose. The following database can be used for selection of a student issuing questions. (4) Database to analyze student achievement: A serious problem of CAI systems is that it is required to prepare teaching materials in advance by considering all possible cases. In a distance education system on the other hand, we can improve teaching materials by repeated teaching experiences. We will store abstracted information of student actions during the lecture, which can be used to improve the teaching material. The database can be regarded as a kind of temporal databases. The database also stores past achievement of each student. Extensive use of such database technology is promising way for next-generation distance education systems.
