ABSTRACT
The capabilities of the technology may outrun the experience and expertise of the creative trainers who want to exploit the software. Important developments are occurring that will bring the power of electronic publishing software to bear in authoring computer-based training (CBT). Expert system shells can be described as elaborate authoring systems, usually using PROLOG, and capable of introducing artificial intelligence techniques into CBT. Despite several decades of research on educational television, and recent work on educational video, little is yet known about how trainees interact with dynamic video images. Even less is known about how they interact with these images integrated with text, as in interactive video. Frames of text on the computer can, however, be easily integrated electronically with sound, animation, graphics, spreadsheets and databases. Developers of the systems attempted to teach topics such as communication and management skills, without considering whether the medium was appropriate, given the relatively unsophisticated level of development of expert systems technology.
