Data collected by the Corporation for Public Broadcasting indicate that more than 70 percent of all institutions of higher education make some use of television. Ten percent use it only for noninstructional purposes such as promotion, recruitment, or staff development; 61 percent use it for instruction; and 36 percent use it to supplement existing courses. Tracking the exact number of students enrolled in courses using television is complicated by problems of definition and unavailability of adequate data. However, studies indicate that in 1979, about one half million students were enrolled in more than 6,000 courses offered over television. Data on the use of radio are just beginning to be available. So far, figures collected indicate that 53 percent of all institutions of higher education used radio for instructional purposes in 1979. Those colleges and universities offered a total of almost 10,000 courses involving substantial use of radio and enrolled almost one half million students in those courses. A variety of factors which hinder the use of television and radio for instruction in higher education is identified for three levels: institution, faculty, and student. (Author/LLS)
