ABSTRACT
This chapter concentrates on the pedagogic ones, including the problem of motivation of both students and teaching staff. Distance teaching methods, as compared with the more traditional face-to-face teaching, involves quite different costs in terms of both money and manpower for the providers, as well as quite different cost structures. Nowadays, in distance teaching, naming the subject is only a part of the matter, even though it is a very important part. The variety of types of audience, and the greater opportunities for access they have, brings about a demand for a much wider range of subject matter, from professional courses through academic and practical courses to community interest courses. The use of redundancy simply means teaching the same ideas in several different ways: for example, analysing them in terms of other concepts, by analogy, by applying them in different contexts, by contrasting them with alternative ideas, by repetition but in different words, by the use of different media.
