Importance of dissection in learning anatomy: personal dissection versus peer teaching.
Full Abstract
Two studies or approaches to time savings in teaching gross anatomy were implemented and tested. Personal dissection vs. peer teaching of the upper and lower extremities revealed subtle effects of dissection on examination performance. Although peer teaching was generally successful, students preferred to dissect for themselves, lacking confidence in being taught by other students. ANOVA and multiple range tests carried out on the examination means indicated no difference between each student's scores on upper and lower extremity questions. However, subtle effects were reflected in significant differences (P < 0.05) in both ratio (upper%/lower%) and difference (upper%-lower%) between each student's percent scores on upper extremity and lower extremity questions, indicating enhanced performance on the extremity dissected. Students dissecting both extremities were intermediate in both ratio and difference, and not significantly different from either the "upper" or "lower" extremity groups. A questionnaire indicated that students who dissected only one extremity would have preferred to have dissected both extremities, and, contrary to overall examination performance, disagreed that they had learned both extremities at a satisfactory level. Although documenting adequate learning with time savings, the results are consistent with the contention that hands-on dissection enhances learning and confidence in the subject matter, because examination performance as well as personal satisfaction was enhanced on the extremity that was dissected.Copyright 2002 Wiley-Liss, Inc.
