There is a growing global interest in extending the field of study from stand-alone learning environment to collaborative or cooperative learning environment. In the light of the recent explosive growth of information communication technology, the platform for collaborative or cooperative activities should be revisited. This paper investigates the technological challenges in using distributed multimedia in a collaborative learning environment and proposes an architecture for multimedia processing in the collaborative learning environment. V-Class, a Java application suite with intensive distributed multimedia support, has been developed and deployed, allowing collaborative learning between students and tutors at remote locations. Students can engage in group activities and also collaborate with tutors. Each student sees a common shared window on which text or graphical objects may be added and which can then be shared online. A built-in chat room supports collaborative dialogue. Students can work either in collaborative groups or in teams as directed by the tutor. This paper summarizes the technical architecture of the V-Class system as well as the pedagogical implications of the suite.
