ABSTRACT

Recent developments in technology are bringing advantages to distance teaching and removing some of the disadvantages previously associated with the use of audio-visual media. One of the major benefits of computers and cassettes is that they enable students to develop skills, through structured activities, practice, and feedback. Media such as television and computers provide source material which students can work on to expand their understanding and to which they can apply their knowledge. Different media provide alternative ways to reach understanding and comprehension, and in distance education, where tutor-student contacts are limited, a variety of presentation is essential. The use of media is essential for teaching science and technology at a distance. Far from eliminating human contact, technologies such as the telephone and cyclops make possible personal tutorial contact where otherwise it would be impossible for remote or isolated distant students.
