Medical student assessment of videotape for teaching in diagnostic radiology.

A series of six videotape recordings, prepared jointly by the Department of Radiodiagnosis and the Television Service, University of Leeds, described some aspects of the radiology of the chest, using only radiographs. A small group of final year medical students viewed these videotapes over the space of few days. Their scores for factual questions immediately afterwards were compared with their attitudes to the learning experience, expressed anonymously without knowledge of these scores. Students who scored the highest marks were most consistently critical of the videotapes; those with lower marks tended to record favourable attitudes when they performed best and unfavourable attitudes at other times. Scales set up by the students themselves to evaluate the experience produced a wide range of detailed and constructive suggestions. In general, students commented very favourably on the capacity of videotape to present fine radiographic details and we conclude that it is an appropriate medium for this purpose.
