"The object of this document is to attempt to identify the prerequisites for an efficient use of modern communication media for formal and non-formal educa tion in rural areas in developing countries [...] Although one cannot entirely separate the way the teaching process is treated from the way the organisational aspect is handled, the purpose of this study is to examine the factors on the organisational side which make for an efficient use of media, based on the results of more than tventy years' experience throughout the world. In view of the variety of media available and the considerable difference in the requirements of the various countries, there can be no question of recommending a specific type of organisation. Our aim is a far more limited one, i.e. to highlight what, judging by this experience, are the most common organisational problems encountered in the use of modern communication media in education and to describe how the technical constraints inherent in the media affect methods of organisation, bearing in mind the specific characteristics of the rural environment."
