Rationale and Objectives: Medical student surveys are used extensively in the development and modification of curriculum. The purpose of this study was to look at medical student surveys of a radiology lecture series, evaluating the accuracy of student perceptions of learning and factors affecting them., Materials and Methods: After a "Case of the Week" lecture series, 156 3rd-year medical students returned a survey evaluating the experience with 10 questions on a four-point scale (1 = disagree, 4 = agree very much) and took a clinical competency assessment (CCA) examination with a radiology substation. Survey responses were compared with actual examination performance, analyzed for how overall learning was characterized in specific educational objectives, and evaluated for factors affecting perceived learning., Results: The mean response for perceived CCA examination preparedness was 1.83. The mean radiology station test score was 90.43%. Correlations between student perception of learning and the scoring of focused learning objectives ranged from 0.33 to 0.48 (P < .01). Students responding 1 to items assessing perceived lecture organization, stimulation to read, and interest in the field of radiology had mean scores for perception of overall learning of 2.09-2.44 and mean scores for recommendation of course continuation of 1.68-2.46. Students responding 4 had means of 3.25-3.81 and 3.06-4.0, respectively., Conclusion: Student perceptions of the value of curriculum were inaccurate compared with external measures of performance, and students poorly related their general impressions to specific learning objectives. Perceived lecture organization, stimulation to read, and interest in radiology as a specialty affected perceived overall learning and perceived value of the lecture series.

Rationale and Objectives: The Comprehensive Clinical Assessment (CCA) examination at the University of Michigan Medical School is a series of test stations through which the mastery of clinical skills is evaluated. The purpose of this study was to determine whether student performance on the radiology station improved in years when radiology faculty presented case-of-the-week unknowns to the 3rd-year students., Materials and Methods: The authors compared four separate classes of medical students in examination years 1993, 1994, 1995, and 1996 by using the total CCA examination score, the radiology station score, and radiology station pass/fail rates. Radiology case-of-the-week presentations were given by the radiology faculty only in academic years 1993-1994 and 1994-1995 (examination years 1994 and 1995)., Results: The means and standard deviations of the radiology station scores for the examination years when case-of-the-week presentations were not given, 1993 and 1996, were 78.92 +/- 13.62 and 79.76 +/- 13.62, respectively. In the years case-of-the-week presentations were given, 1994 and 1995, the radiology station scores averaged 90.83 +/- 8.58 and 89.97 +/- 9.66, respectively (P < .001, global alpha = .05). Total CCA percentage correct scores were similar for all years studied. In 1993 and 1996, 7.6% and 5.3% of students, respectively, failed the radiology station. In 1994 and 1995, 0.4% and 0% of students, respectively, failed (P < .0001)., Conclusion: Case-of-the-week presentations by radiology faculty increased 3rd-year students' basic radiologic knowledge as evidenced by increased scores on the radiology station of the CCA examination.

Rationale and Objectives: Clinical competence certification is now required in some specialties in medicine. A Comprehensive Clinical Assessment (CCA) was created to test mastery of critical skills by students at the end of the 3rd year of medical school., Methods: The CCA is a series of stations that test skills the faculty consider important for all medical students (eg, breast examination, electrocardiogram reading, chest pain assessment, ophthalmology photographs). The radiology station was designed to evaluate imaging skills believed to be taught and learned in the core 3rd-year rotations., Results: External measures (National Board Examinations, grade point average, and overall score) of clinical performance of the 608 medical students who completed the CCA examination between 1991 and 1993 were found to be correlated with the radiology station scores., Conclusion: The radiology station in the CCA examination is a reproducible measure of clinical performance.
