Abstract
This paper describes the concept and the implementation of an individual tutoring system called CALAT, which is integrated in the distributed hypermedia environment of World-Wide Web (WWW). The first implementation of CALAT is an extension of the conventional server/client of WWW, including an intelligent tutoring system(ITS) on the server side and a multimedia scene viewer on the client side.
In this implementation, the ability to adapt to individuals is made possible by a newly developed user identification technique and a viewer control protocol. The CALAT's second implementation will employ a totally different architecture in which coursewares will be distributed over the WWW servers. This implementation provides the potential for constructing courseware utilizing not only an enormous mount of multimedia resources on WWW but chunks of other coursewares distributed all over the world.
