A decentralized system of Closed Circuit Television (CCTV) was established in clusters of six to nine ghetto elementary schools in Chicago to increase the relevance of televised instruction, allow each group to provide its own curriculum, and to involve classroom teachers in program development processes. An additional benefit, that the programs provided teaching models for insecure beginning teachers (a sort of inservice teacher education), was discovered. Each cluster of the Chicago system generates programs for subject matter areas arranged by level of difficulty, and provides supplementary worksheets and booklets for each presentation. Implementation and utilization costs were found to be generally less than that of many currently operating instructional television systems. Also, low cost advantages of a centralized system were exploited by adapting centrally filmed segments, such as demonstrations, and "on location" filming to each cluster's programing. Implications for future elementary school education indicate an increasing use of instructional media for lesson presentations and a trend toward a diagnostic, individual counseling role for the teacher.
