Diagnostic radiology is expanding, playing an increasingly central role in patient care, which heightens the importance of radiology teaching in undergraduate medical education. This study examined the impact of increased structure and systematic evaluation on student performance in a radiology elective. The evaluation protocol included premultiple and postmultiple choice examinations (70 questions each), a film interpretation quiz (ten films, 20 questions), faculty assessment of a student oral case presentation, and student evaluations of the elective experience. The relationships among the evaluation techniques, as well as differences in class level and course ratings were also examined. Two different treatment groups were studied. Group 1 was given general objectives and information regarding availability of recommended resources, including self-learning materials for the elective, didactic seminars, and viewbox exposure. Group 2 was given specific written instructional objectives, a structured schedule for viewing the self-learning materials, and the same seminars and viewbox exposure. The statistically significant higher performance of the structured group suggests that medical students achieve the objectives of an elective better when learning activities are well defined, structured, and systematically evaluated. In addition, those students receiving the structured experience rated the radiology elective more favorably.
