It is a matter of some importance for institutions of further and higher education to investigate ways of improving teaching effectiveness. Many studies have been undertaken in both Europe and elsewhere. These have, in general, been published in the academic journals and a number of conferences have been held to discuss the techniques proposed. Almost without exception, the proposals which have been considered rely on behaviourally orientated methodologies akin to the many techniques currently in use in the USA (and in other countries where teaching assessment is common practice). It has been the author's contention that such techniques are an inappropriate way of improving teaching effectiveness as they demand a pre-specification of criteria deemed to be appropriate, the teacher is then assessed against this ‘ideal profile’. It is the author's view that the teacher should be perceived as a professional, capable of undertaking his task with autonomy. This is particularly valuable if a mechanism exists to assist him in identifying his strengths and weaknesses so that he can capitalise on the former whilst endeavouring to eradicate the latter (through the application of appropriate staff development). Thus, in 1975, as part of a doctoral research project, the author devised a teaching appraisal system which became know as TARGET. TARGET is an acronym for Teaching Appraisal by Repertory Grid Elicitation Techniques and is based on the principles of Personal Construct Psychology. The primary objective when using the TARGET system is to raise the perceptual awareness of the teacher to his strengths and weaknesses, this, in turn, may enable him to become more effective at this job. However, the system remains far less threatening than those aforementioned behavioural techniques. Since 1975, the author has continued his research and whilst TARGET has been, and is still, used in a number of institutions of further and higher education in the UK, USA, Australia and even India, the methodology developed has been refined and improved over the intervening period. Consequently, the technique now proposed by the author as the most efficient way of raising perceptual awareness (and thus achieving the same goals as the TARGET system), is to encourage individual lecturers to sit in front of a small microprocessor and interact with a programme, (designed using the same principles of Personal Construct Psychology), such that feedback can be given immediately in terms of his strengths and weaknesses. This paper briefly considers the TARGET system as it was devised, the interactive computer programme as it is currently used at Garnett College, (and some other institutions in Europe and Australia) and finally, illustrates the principles underlying both the TARGET and interactive computer programme by describing the game of MISUNDERSTOOD, which can be played without the hardwear support, of the video or computing kind, necessary in both the former methods. MISUNDERSTOOD can be played in groups of three or four (with a number of groups playing simultaneously) as a one-off staff development exercise. It has already been successfully used by an international motor company, a number of educational institutions and the Prison Education Officers Training Scheme. The author contends therefore, that raising perceptual awareness by any of the three methods described in this paper makes a positive and worthwhile contribution to the improvement of the effectiveness of the FE teacher, and supports this with evidence drawn from his experience of applying the techniques in a number of institutions in which he has been employed and had some responsibility for Staff Development.
