The impact of telecommunication technologies on vocational training

Objective: to outline the potential for effective and efficient interactive distance education systems made possible by recent advances in telecommunications technologies.
The lecture will review the systems for interactive conversational group training that have become available over the last few years. These include audio-(telephone-)based teleconference systems, audiographic systems (in which the graphic or visual component may be supplied by a variety of means including fax, electronic blackboards, slow scan video, interlinked computers, etc.), videoconferencing systems (one and two way video) and networked computer conferencing systems. We will also review the developments in networks and delivery systems, including the current state of the art in satellite communication and ISDN.
