Three Models for Home-Based Instructional Systems Using Television.
Case studies of three very different successful TV educational programs, with a discussion and checklist of the stages and components in developing successful uses of educational television. The examples are (1) [Sesame Street]; (2) Chicago's [TV College], a junior college degree program; and (3) Bavaria's [Telekolleg], preparation for the middle-level vocational degree examination. [TV College] and [Telekolleg] combine TV with printed materials, in-person seminars, faculty-student communication, and examinations. Cost per viewer per program varies by a factor of 1000, from [Sesame Street]'s $0.004 to [TV College]'s cost per credit student of $3.75. Per college credit hour, [TV College] averages $42 per student, 84 percent of on-campus instruction, while [Telekolleg] costs only 20 percent as much as conventional instruction. Important in the success of TV instruction are adequate preplanning, audience targeting, promotional contact with viewers, evaluative feedback, and the flexibility to adapt to it. 68 pp. Ref.
