title: The audio-visual revolution: do we really need it?
abstract: In the United Kingdom, The audio-visual revolution has steadily gained converts in the nursing profession. Nurse tutor courses now contain information on the techniques of educational technology and schools of nursing increasingly own (or wish to own) many of the sophisticated electronic aids to teaching that abound. This is taking place at a time of hitherto inexperienced crisis and change. Funds have been or are being made available to buy audio-visual equipment. But its purchase and use relies on satisfying personal whim, prejudice or educational fashion, not on considerations of educational efficiency. In the rush of enthusiasm, the overwhelmed teacher (everywhere; the phenomenon is not confined to nursing) forgets to ask the searching, critical questions: 'Why should we use this aid?','How effective is it?','And, at what?'. Influential writers in this profession have repeatedly called for a more responsible attitude towards published research work of other fields. In an attempt to discover what is known about the answers to this group of questions, an eclectic look at media research is taken and the widespread dissatisfaction existing amongst international educational technologists is noted. The paper isolates out of the literature several causative factors responsible for the present state of affairs. Findings from the field of educational television are cited as representative of an aid which has had a considerable amount of time and research directed at it. The concluding part of the paper shows the decisions to be taken in using or not using educational media as being more complicated than might at first appear.
