This paper discusses media comparison studies and reasons that research of this nature is pursued, especially in the area of computer-based interactive video (CBIV). Three scenarios are presented to demonstrate instances in which the knowledge of the relative effectiveness of CBIV is important and useful: (1) the case of the administrator who…

This examination of the educational and economic advantages of using videocassettes instead of broadcast television for Open University distance education begins by noting that, while the potential importance of television in distance education is widely recognized by educators, students appear to be less appreciative.

The costs of three types of transmission technology in distance education are compared, and the costs for equipping and installing a distance education classroom are estimated. Two of the technologies--fiber optics and microwave--deliver two-way, full motion video and two-way audio. The third technology, compressed video, also delivers two-way…

Compares the use of computer-based training (CBT) and interactive videodisc (IVD) for education and training. Highlights include research about CBT, including administrative strengths, cost effectiveness, motivation, feedback, and lesson control; steps involved in producing CBT and IVD materials; research about IVD, including content and learner…

A study of eighth grade science students compared the instructional effectiveness and the cost effectiveness of an interactive video system with the use of 16mm films for teaching a science unit. Results indicated that interactive video can be significantly more effective than conventional methods of instruction. (eight references) (LRW)
