Collaborative Learning On-Demand on the Internet Mbone

Abstract

The ubiquity of the Internet potentially allows delivering a variety of electronic learning contents to a wide audience. This work proposes a new online learning paradigm, namely, collaborative learning on-demand (CLoD), and its supporting technology. The CLoD paradigm enables a group of workmates to on-demand request and watch the playback of an archived multimedia session for the purpose of collaborating and cooperatively constructing knowledge. CLoD is featured by cooperative playback systems, which are networked infrastructures providing collaborative media on-demand services. The chapter also details our MBone-based cooperative playback system, ViCROC, and presents an investigation of its usability.
