In 1961 a three year study was inaugurated in Hampshire County, England, to investigate the possible applications of closed-circuit television in secondary schools. The study included investigations of new teaching methods and of the technical, financial, and administrative arrangements prerequisite to the use of television on a large scale. The first phase focused on the use of the equipment in a single classroom which was then linked to a second classroom. The second phase saw the construction of a studio and the linking of the original school with two others by cable. Studio teaching methods, production techniques, program content, and the balance between enrichment and curriculum materials were the foci of this phase. The third phase was concerned with an objective program assessment, consisting of a series of controlled experiments to ascertain the most effective uses of the television medium. Some of the more important findings indicate that television teaching is equal or superior to conventional instruction; programs must be directed to a limited ability range; students show high interest in locally produced programs; lesson and teaching notes should be issued for each broadcast; and a talk-back system on a limited scale is effective for establishing pupil-teacher communication. The report includes information on facility design and administration, production techniques, and staff use. (MT)
