Future Development of Instructional Television.
Barnett, H. J.; Denzau, A. T.
Instructional television (ITV) has been little used in the nation's schools because ITV hardware and software has been unreliable and expensive and teachers have yet to learn to use ITV. The perfection of inexpensive videotape recorders/players (VTR) and inexpensive tapes and cameras could remedy the problem. A package consisting of 10 mobile VTR's and television sets, a tape library, and several TV cameras per school of 50 rooms and proportionate equipment for schools of other sizes would cost only about $5 per student per year. If an active head-end at each school transmits the ITV programs by cable to the classroom it would cost about $33 per student per year. The cost of school ITV could be lowered by a dedicated school district cable system--a 40 channel cable to each school and thence to each classroom. The Federal Communications Commission sponsored 4-channel fixed service would provide less flexibility and would be slightly more costly for approximately equal service to classrooms. Although satellite distribution has been proposed for ITV in the United States, a lack of knowledge of the cost of satellites and satellite reception equipment makes it difficult to reliably estimate costs. Satellite distribution, however, should become increasingly possible in the future. (JY)
