The retrospective pre-post: a practical method to evaluate learning from an educational program.

OBJECTIVES: Program evaluation remains a critical but underutilized step in medical education. This study compared traditional and retrospective pre-post self-assessment methods to objective learning measures to assess which correlated better to actual learning. METHODS: Forty-seven medical students participated in a 4-hour pediatric resuscitation course. They completed pre and post self-assessments on pediatric resuscitation and two distracter topics. Postcourse, students also retrospectively rated their understanding as it was precourse (the "retrospective pre" instrument). Changes in traditional and retrospective pre- to postcourse self-assessment measures were compared to an objectives-based multiple-choice exam. RESULTS: The traditional pre to post self-assessment means showed an increase from 1.9 of 5 to 3.7 of 5 (p < 0.001); the retrospective pre to post scores also increased from 1.9 of 5 to 3.7 of 5 (p < 0.001). Although the group means were the same, individual participants demonstrated a response shift by either increasing or decreasing their traditional pre to retrospective pre scores. Scores on the 22-item objective multiple choice test also increased, from a median score of 13.0 to 18.0 (p < 0.001). There was no correlation between the change in self-assessments and objective measures as demonstrated by a Spearman correlation of -0.02 and -0.13 for the traditional and retrospective pre-post methods, respectively. Students reported fewer changes on the two distracters using the retrospective pre-post versus the traditional method (11 vs. 29). CONCLUSIONS: Students were able to accurately identify, but not quantify, learning using either traditional or retrospective pre-post "self-assessment" measures. Retrospective pre-post self-assessment was more accurate in excluding perceived change in understanding of subject matter that was not taught.

Learning while evaluating: the use of an electronic evaluation portfolio in a geriatric medicine clerkship.

BACKGROUND: Electronic evaluation portfolios may play a role in learning and evaluation in clinical settings and may complement other traditional evaluation methods (bedside evaluations, written exams and tutor-led evaluations). METHODS: 133 third-year medical students used the McGill Electronic Evaluation Portfolio (MEEP) during their one-month clerkship rotation in Geriatric Medicine between September 2002 and September 2003. Students were divided into two groups, one who received an introductory hands-on session about the electronic evaluation portfolio and one who did not. Students' marks in their portfolios were compared between both groups. Additionally, students self-evaluated their performance and received feedback using the electronic portfolio during their mandatory clerkship rotation. Students were surveyed immediately after the rotation and at the end of the clerkship year. Tutors' opinions about this method were surveyed once. Finally, the number of evaluations/month was quantified. In all surveys, Likert scales were used and were analyzed using Chi-square tests and t-tests to assess significant differences in the responses from surveyed subjects. RESULTS: The introductory session had a significant effect on students' portfolio marks as well as on their comfort using the system. Both tutors and students reported positive notions about the method. Remarkably, an average (+/- SD) of 520 (+/- 70) evaluations/month was recorded with 30 (+/- 5) evaluations per student/month. CONCLUSION: The MEEP showed a significant and positive effect on both students' self-evaluations and tutors' evaluations involving an important amount of self-reflection and feedback which may complement the more traditional evaluation methods.
