A pilot study to develop a methodology for educational planning. Colombia was chosen for analysis primarily because there is a relatively extensive educational television (ETV) project currently under way from which data of a type unavailable elsewhere could be obtained. The analysis considers the technology as it interrelates with the entire educational system in which it is to function, and proposes alternative means to attain similar improvements in that system. Four alternatives for improving the primary-school system and four for the secondary-school system are examined, including the use of ETV. In all of the alternatives, the major expenditures are for building up and maintaining a viable educational base--the teacher-training program, increased teacher salaries, and more and larger schools. The cost of upgrading education through the use of ETV is shown to be competitive with that of the traditional method--providing more teachers. Only half as many additional qualified teachers would be needed in a system using ETV. In the case of Colombia, it might be impossible to improve the quality of education without an effective substitute for some of the trained teachers needed. 150 pp. Ref.
