ABSTRACT
The purpose of this chapter is to describe a multifunction microcomputer-based enhancement of audio teleconferencing. As a framework for discussion, distance education technologies are structured into three generations – correspondence, teleconferencing, and computer-based. It is argued that microcomputer-enhanced audio teleconferencing represents a move into the third generation (computer-based) of distance education delivery. While audio teleconferencing represents significant advances over correspondence study in terms of its communications capabilities, there does not exist an ability to interact visually in real time or provide continuous support and guidance. As a result of a discussion of common audiographic systems it was concluded that a microcomputer-based system which can support telewriting, computer-assisted learning, computer messaging, and computer graphics represents the most cost-effective multipurpose enhancement of audio teleconferencing available today. The system is designed for the addition of other technology (e.g. videodisc, videotex), thus providing a foundation for future developments and reducing the possibility of technological obsolescence. It is anticipated that the additional communications capabilities of this system will not only improve the quality of audio teleconferencing in general, but will make it possible to deliver courses requiring a visually interactive medium which were not previously possible.
