Per studentequivalentannualcosts are estimatedfor airborne television,InstructionalTelevisionFixed Service(ITFS),satellitetelevision, UHF television, closed circuittelevision,video tape recordings,film,radio, language laboratories, and dial access systems. The appendix analyzes componential and operating costs for five media systems (instructional television, audiovisual media system1 educational radio, learning and language laboratories, dial access), using guidelines established in VolumeI of the study. Estimated costs are presented graphically with price ranges and design considerations. Researchers must examine the possibilities of cost savings in media development and consider the relationship of instructional technology to the educational system, government, and the knowledge industry.
