Abstract

BACKGROUND:

Little objective evidence exists regarding what makes a good lecture. Our purpose was to determine qualities of radiology review course lectures that are associated with positive audience evaluation.

METHODS:

57 presentations from the Ottawa Resident Review Course (2012) were analyzed by a PGY4 radiology resident blinded to the result of audience evaluation. Objective data extracted were: slides per minute, lines of text per text slide, words per text slide, cases per minute, images per minute, images per case, number of audience laughs, number of questions posed to the audience, number of summaries, inclusion of learning objectives, ending on time, use of pre/post-test and use of special effects. Mean audience evaluation scores for each talk from daily audience evaluations (up to 60 per talk) were standardized out of 100. Correlation coefficient was calculated between continuous variables and audience evaluation scores. Student T test was performed on categorical variables and audience evaluation scores.

RESULTS:

Strongest positive association with audience evaluation scores was for image quality (r = 0.57) and number of times the audience laughed (r = 0.3). Strongest negative association was between images per case and audience scores (r =‚ÄČ-0.25). Talks with special effects were rated better (mean score 94.3 vs. 87.1, p < 0.001). Talks with the highest image quality were rated better (mean score 94.1 vs. 87.5, p < 0.001). Talks which contained a pre/post-test were rated better (mean score 92 vs. 87.8, p = 0.004).

CONCLUSION:

Many factors go into making a great review course lecture. At the University of Ottawa Resident Review Course, high quality images, use of special effects, use of pre/post-test and humor were most strongly associated with high audience evaluation scores. High image volume per case may be negatively associated with audience evaluation scores.
