In the anatomy laboratory, skill remains a critical component to unlocking the true value of learning from cadaveric dissection. However, there is little if any room for provision of instruction in proper dissection technique. We describe how near-peer instructors designed a supplemental learning activity to enhance the dissection experience for first-year medical students. This study aimed to evaluate the efficacy of this curriculum in improving participants' understanding of dissection technique and its impact on perceived challenges associated with the anatomy course. Curriculum was designed under faculty guidance and included didactic sessions, low-fidelity models, dissection, student presentations, and clinical correlations. Participants' (n = 13) knowledge of basic dissection techniques and concepts were assessed before the selective, and both participants' and nonparticipants' (n = 39) knowledge was assessed at the end of week one and week seven of the anatomy course. Scores were compared using repeated measures ANOVA followed by post hoc t-tests. Thirteen deidentified reflective essays were reviewed by four independent reviewers for themes that aligned with learning objectives. Participants in the selective course scored higher on assessment of dissection techniques and concepts one week after the selective compared to both nonparticipants and their own baseline scores before the selective. Analysis of student reflections resulted in four themes: confidence with dissection skill, sharing resources and transfer of knowledge, learning environment, and psychological impact of perceived challenges of the anatomy course. Near-peer driven supplemental exercises are effective in facilitating dissection skills. This dissection primer increases student confidence and alleviates apprehension associated with anatomy courses.
在解剖实验室中,技能仍然是从尸体解剖中获取学习真正价值的关键要素。然而,在提供正确解剖技术的教学方面几乎没有空间。我们描述了近伴导师如何设计一项补充学习活动,以增强一年级医学生的解剖体验。本研究旨在评估该课程在提高参与者对解剖技术的理解及其对解剖课程相关感知挑战的影响方面的效果。课程在教师指导下设计,包括理论课程、低保真模型、解剖、学生展示以及临床关联。在选择性课程之前评估了参与者(n = 13)对基本解剖技术和概念的知识,在解剖课程的第一周和第七周结束时评估了参与者和非参与者(n = 39)的知识。使用重复测量方差分析,随后进行事后t检验比较分数。四位独立评审员审查了13篇匿名反思性文章,以找出与学习目标一致的主题。与非参与者以及他们自己在选择性课程之前的基线分数相比,选择性课程的参与者在选择性课程一周后对解剖技术和概念的评估中得分更高。对学生反思的分析得出了四个主题:解剖技能的信心、资源共享与知识转移、学习环境以及解剖课程感知挑战的心理影响。近伴驱动的补充练习在促进解剖技能方面是有效的。这本解剖入门教材增强了学生的信心,并减轻了与解剖课程相关的担忧。
