At the University of Texas Houston Medical School, a rotational dissection system was introduced to improve coordination between the Gross Anatomy and the Introduction to Clinical Medicine (ICM) courses. Six students were assigned to each cadaver and divided into two teams. For each laboratory, one team was assigned to dissect and the other to attend ICM or study independently. For the next laboratory, the assignments were reversed. At the start of the session, the team that had dissected previously spent 30 minutes teaching the other team. In 2012, the students were given three traditional practical examinations with 50 questions drawn equally from each laboratory. Students also completed three mid-course evaluations. There were no significant differences in overall performance between the two teams. Nevertheless, we wanted to determine how well individual students identified structures they had dissected compared with those they had not. For dissected structures, the mean percent correct was 80.0?±?13.0 (mean?±?standard deviation), and for undissected structures, it was 78.3?±?14.1. The difference was small, but statistically significant (P?=?0.0007). Although this result validated the concerns expressed by some students, it did not appear that a change in the system was justified. Students were generally enthusiastic about the opportunity to learn clinical skills in the first semester of medical school, and 91-96% of the students agreed that learning anatomy at the same time helped them understand the physical examination exercises in ICM.
