Low-cost video-films in the teaching of undergraduate and postgraduate medical students

The high cost of producing good-quality video-films for teaching has hindered the use of this method, which has been shown to improve significantly the efficiency of teaching and the retention of knowledge. During the last five years, a series of short video-films has been produced using inexpensive video-cameras and home video-recording and editing equipment. A variety of techniques were developed to allow recording of lecture presentations, while using the equipment as a teaching aid, without the need for technical staff. The positioning of the camera, the monitor, the slide projector and lighting were critical to the productions. Similar productions at low cost were obtained from recordings of operating theatre sessions, tutorials and clinical ward rounds. A survey of students exposed to teaching with video-film as part of a lecture presentation confirmed that the subject matter being taught was more easily understood and enjoyable and generated more discussions on than other forms of teaching.
