Abstract
It is argued that auditory and audio‐visual materials will play an increasing part in programmed instruction in the future. In some areas, especially in the teaching of reading and languages, and in the direct teaching of people who cannot read, audiovisual programs are practically a necessity. Work already carried out in these areas is surveyed. But if psychological evidence to the effect that the use of both audio and visual modalities can produce more effective teaching than the use of either modality alone is correct, then a general use of audio‐visual programs emerges. In any case, an advantage might be expected for audio programs in a number of specific areas, such as in some industrial training situations, and when programs are used in a group situation. There may also be a future for audio‐visual programs presented via the mass media of radio and television. Research related to all these possible uses of audio‐visual programs is surveyed. An audio‐visual teaching system developed at Educational and Scientific Developments Ltd. is described, as are some experiments carried out using it. Some recent work in which this system is used with severely subnormal children is reported briefly.
