Randomized Controlled Trial Comparative Study Clinical Trial
Videotaped vs traditional lectures for medical students.
Closed-circuit television (CCTV) provides medical departments with alternatives in instructional formats. Concern, however, has been voiced about teaching via TV because the medium itself might cause inattention. This study investigated whether TV will lower the test scores of medical students. ⋯ To detect attitudinal differences toward the two formats, the students were surveyed at the end of the series and intragroup agreement on specific questions was calculated. The students rated the lecture format more highly. In response to the question 'Did the audiovisual materials used by the instructor aid your learning?', the mean rating from the lecture group was 7.37 (scale of 0-9) compared to a mean rating of 5.93 from the video group (P < 0.0003).
