Two authors discuss educational technology innovations, costs, and effectiveness. Sidney Tickton summarizes the CIT report of 1969-70 and new data highlights from the present study. He recommends that government agency sponsors of technology projects demand cost and result information and comparative studies with other systems presenting identical offerings. Sherwood Kohn sets forth the study objectives: (1) probe further into educational technology cost, and (2) attempt to assess potential benefits and costs of educational technology innovations. Mr. Kohn relates that the costs of educational TV, computer teaching techniques, and audiovisual aids were reviewed; the results of technological innovation in "controlled" environments and in disadvantaged and experimental schools examined; and the effect of new educational tools and techniques on productivity determined. Data were gathered from consultations with over 50 authorities; polls of 90 educational TV stations and 50 State education departments; searches at ERIC centers for new reports on instructional technology; and from analysis of reports published by local school units. Data revealed that TV and computers, because of their cost effectiveness promise, are being accepted as teaching tools in crucial areas, and that there exists a deeper understanding and a greater use of technology by educators with a corresponding change in emphasis from teaching to learning and from mass to individual instruction.
