Construction of a Web-based virtual classroom and its effective analysis

In classroom, information between teachers and students includes course content and learning scene. Course content is mainly information, and learning scene is assisted information that can effectively prompt learners exchanging idea and acquiring knowledge. A based-Web virtual classroom should have the same features. Because of the limitation of bandwidth and QoS of network, it is very difficult to transfer teaching and learning information by video in Internet. The paper probes into a strategy of developing virtual classroom by the streaming media technologies. By contrast with two kinds of information, the Web-based virtual classroom we built includes two parts: real time teaching environment (RTTE) and collaborating learning environment (CLE). RTTE transports course content and feedback information into teachers or students. This paper firstly discusses the strategies of creating a virtual classroom for the remote learners. Secondly, it designs the architecture of a virtual classroom.
