의학교육과정의 개편으로 해부학 강의 시간이 감소하면서 학생들이 참여하는 해부실습 시간을 보다 효율적 활용할 수 있는 교수 전략에 대한 관심이 높아지고 있다. 본 연구의 목적은 상호동료교수법을 활용한 교대해부실습(alternating dissection)이 실습시험 성적에 미치는 영향을 분석하는 것이다. 의과대학 의학과 1학년 학생을 가나다 순서로 각 실습대에 8~9명씩을 배정하였다. 각 조원을 다시 A조와 B조로 나누어 해부조와 관찰조로 분류하여 번갈아 가면서 해부실습을 진행하였다. 해부를 하지 않는 관찰조는 팀바탕학습을 기반으로 하는 자기주도학습을 실시하고, 당일의 해부를 마치면 해부조는 관찰조에게 동료가르침을 하였다. 새로운 실습방법과 전통적 실습방법에 따른 실습시험 성적은 유의한 차이를 보이지 않았으며, 교대해부실습에서 A조와 B조 사이의 실습시험 성적도 유의한 차이를 보이지 않았다. 그러나 부위에 따른 문항 분석에서 직접 해부한 부위에 해당하는 문항의 정답률이 관찰한 부위에 해당하는 문항의 정답률에 비해 유의하게 높았다. 정답률에서 유의한 차이를 보이는 문항은 전체 86개 문항 중에서 9개 문항이었다. 결론적으로, 의과대학 1학년 학생의 해부실습에서 상호동료교수법을 활용한 교대해부실습의 효용성을 확인하였다. 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.

This study was conducted to analyze the strengths and weaknesses of a 3-week family medicine clerkship program based on the results of an online survey taken by the students (N=127) and a structured interview with a focus group (n=10), aimed to improve the quality of the clerkship program. The online survey contained questions pertaining to goals, schedule, contents, arrangement, atmosphere, environment, evaluation, and satisfaction regarding the clerkship. The focus group interview addressed the schedule and achievements of the program. Scores were reported on a 5-point Likert scale. Most students were highly satisfied with the overall quality of the clerkship. The structured interview results showed that 97.6% of the clerkship program was executed according to the schedule. The focus group reported a perfect score of 5 points on several measures including: accomplishment of the educational goals of the family medicine clerkship, providing many chances to obtain medical histories and perform physical examinations on real patients, experience with various symptoms and diseases, positive attitudes of faculty members when teaching, notification of the guidelines for evaluation beforehand, well-constructed and effective clerkship schedule, and reflection of student feedback. However, the focus group gave low scores on: support for health accidents of students, access to patient information, enough opportunities to practice clinical skills, appropriate rest facilities for students, and fairness of clerkship evaluation process. In conclusion, the structured evaluation performed after the 3-week clerkship program motivated students and helped them ensure an efficient clerkship. This structured evaluation also suggested basic data to make the professor who is subject of the assessment. This study shows that structured assessment is an effective method which can be used to improve the quality of clerkships.
