This volume contains a collection of working papers designed to accompany the case studies of India and Latin America in providing a framework for the planning of educational broadcasting systems. The first two papers offer useful orientation to policy-makers who are considering educational television. Working Paper No. 3 compares the two media of instructional television and film with respect to educational effectiveness and economics of production and distribution. The fourth paper reminds us that communication depends on limited international resources and there are a finite amount of frequency spectrum available and a limited number of "parking slots" for satellites in synchronous orbit. Therefore, conservation must be practiced if maximum benefit is to be derived from what are properly world resources. Characteristics of organizational settings typically found in developing countries are discussed in the fifth paper. Working Paper No. 6 describes and documents the economic analysis used in estimating cost elements of educational television systems. The joint use of both educational television and radio, with radio as a backstop for television was the subject for the seventh and final paper. (HAB)
