Abstract
630 students at a medical school evaluated 18 lecturers who had previously been nominated as ‘most effective’ or ‘least effective’ by over 50 per cent of a sample of 212 graduates from the same school. Lecturers rated as ‘effective’ by the graduates received significantly higher mean scores on each of the dimensions of the teacher rating form (TRF) than did those rated as ‘ineffective’. These results are taken as suggestive evidence that students can distinguish between effective and ineffective lecturers. Whether they will in fact do so under different circumstances is a matter for further research.
