RESUMEN
The reformation of medical curriculum induced the reduction of anatomy course schedule especially in contact hours in anatomy laboratory. It has led to the use of more efficient teaching approaches in anatomy laboratory. The purpose of this work provide a detailed analysis of alternating dissections with reciprocal peer teaching in anatomy laboratory. Students were assigned alphabetically, in teams of eight or nine, to each dissecting table. The team was subdivided into two groups, A and B, each group dissected every other session. Students excused from dissection spent their time with team-based learning and self-directed learning. Dissected peer-teaching groups presented structures from the dissection to groups absent during dissection. Practical exam scores of the alternating dissection indicated no significant difference with those of classical dissection of previous year. Subgroup analysis of practical exam scores in alternating dissection was also no significant difference between group A and B. Assessment of question types showed that correction rates of questions in the dissected region was significantly higher on dissection group assignment. There were 9 questions (out of 86) in which there was a significant difference in correction rates between A and B groups. In conclusion, the laboratory paradigm of alternating dissection with reciprocal peer teaching demonstrated an effective method of learning gross anatomy laboratory for first year medical students.
