A Web-based distributed environment to support teleteaching: design and implementation issues

Web based systems have been shown to be useful tools for supporting educational communication for teachers and students. In this paper we present such a system, which is an integrated distributed learning environment (IDLE). We present the technical description of this IDLE and we discuss its main characteristics like the transmission of multimedia data over the network, the manipulation of the educational procedure and the management of the users. In addition we list the functionalities of the IDLE and also discuss some implementation issues.
