Book excerpt: This book, first published in 1984, provides a comprehensive review of the range of technology that was being used in distance education. Technological developments in word processing, video-disc and viewdata as well as computer-based learning had revolutionised the potential for distance education. These developments required the role of more ’conventional’ distance learning media, such as broadcasting, tuition and text, to be reassessed. This book, written by international experts in the field, explored the state of the art at the time, and also provided their ideas on how future developments were likely to evolve. This book is ideal for those studying education and communications.
