There is no centralized policy for using television and radio for inservice teacher education in Britain. Teacher training colleges have their own low cost production units, two cities have all their schools linked on a closed circuit cable system, and the BBC broadcasts on open circuit one or two series for teachers each year. The largest user of TV and radio for inservice teacher education is the Open University, which provides specially designed multimedia courses leading to a degree. It increases the stock of teachers by allowing working adults to study part-time, and it provides courses to improve the pedagogy of existing teachers. TV and radio are only a small part of the Open University system, the main core of the teaching being specially prepared printed correspondence texts; television and radio tend to be used for functions difficult to achieve through print. Finding sufficient transmission time so all students can view a course is a difficulty, and the facility to transmit a program twice at different times is crucial. Radio is not as well used as television; teachers, in particular, do not use these media as much as other students. However, television is heavily used by students, who do benefit from viewing and listening, and the Open University has a low dropout rate. (Author/JEG)
