Evaluation of peer teaching and deliberate practice to teach veterinary surgery

摘要

Objective To assess the impact of peer teaching and deliberate practice on surgical skills acquisition and retention in first- and second-year veterinary students. Study design Randomized, prospective, comparative study. Sample population Eighteen first-year and 25 second-year students from 1 college of veterinary medicine who had previously demonstrated proficiency in basic surgical skills. Methods Forty-three participants were divided into 3 groups: the test group (group A, n = 15), who participated in a structured peer-assisted learning program using deliberate practice; the time-practice control group (group B, n = 15), who participated in an unstructured peer-supported environment; and the assessment-only control group (group C, n = 13), who participated in the assessments. Participants performed a subcutaneous mass removal on a cadaver model and were assessed via a global rating system. Three assessment points were evaluated: pretraining, immediate posttraining, and retention. Results The number of participants who achieved acceptable or excellent grand total scores in group A increased after training. Among all participants, 22% in group A, 35% in group B, and 38% in group C did not achieve an acceptable total score at the retention assessment. Conclusion The study population improved in skill level and retention through the use of standardized video and peer instruction with attention to effective learning strategies, particularly deliberate practi
