Advanced database functions for distance education system: VIEW Classroom

Abstract

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.

Allocation of Tutors and Study Centers in Distance Learning Using Geospatial Technologies

“…Kagwa and Kambyashi (1997) indicated the importance of using advanced database technologies integration in distance learning which will improve the overall quality of distance learning delivery by maximizing interaction between the learner and the educator [17]. The usage of technology based support system increases the interest of both learner and educator [18].…”
