Abstract
Radiovision is one of the lesser known, successful educational mass media, involving the recording of a sound broadcast, which is then played to its intended audience, together with a specially designed filmstrip. It is cheap, flexible and uses large, high quality, colour illustrations. It has been successful in many parts of the world, e.g. Australia, Africa, and Europe. Research findings are few but indicate the wisdom of extending the medium and further exploiting it. At present, it is used for the 7‐18 age group, though there are variations in use or being tried in higher education, e.g. by the Open University. Its extension as a medium in its own right to a wider variety of subjects, as alternatives to television, in certain circumstances as a means of revising television is desirable. It may be useful to explore other means of equally closely integrated sound/vision programs, using for example, booklets or posters as well as filmstrip. Radiovision needs more research, as do the slide/ tape variations in use. It remains important to exploit existing aids fully especially in view of present financial stringencies.
