Abstract

Purpose: Virtual interactive 3-dimensional models (VI3DM) and immersive virtual reality are implemented in medical education and surgical training. VI3DM allow learners to view and interact with a virtual 3D object and help in conceptualising learning objectives that demand high cognitive and visuo-spatial skills. However, the effects of VI3DM in medical education are unknown. We aimed to determine whether VI3DM are helpful in conceptualising complex anatomical structures. Materials and methods: We included 5 specimens, which were assessed by 200 first-year medical students categorised into experimental (n = 100) and control (n = 100) groups using a systemic randomisation method after matching for age and sex. The experimental group was given VI3DM as interventional learning resources while the control group was given 2-dimensional photographs as conventional learning resources for self-directed learning for 30 minutes. Participants completed a questionnaire before and after the learning session to assess their knowledge related to external features, attachments, and relations of anatomical specimens. Results: The scores of the experimental group improved significantly in the post-test compared to those of the control group for all 5 specimens included in the study (p < 0.05, confidence interval = 95%, unpaired student's t-test). Conclusions: VI3DM can help conceptualise external features, attachments, and relations of anatomical structures.

随机对照试验:虚拟互动三维模型在解剖学和医学教育中的作用。
目的:虚拟交互式三维模型(VI3DM)和沉浸式虚拟现实技术已应用于医学教育和外科培训。VI3DM 允许学习者观看虚拟三维物体并与之互动,有助于实现对认知和视觉空间技能要求较高的学习目标。然而,VI3DM 在医学教育中的效果尚不清楚。我们旨在确定 VI3DM 是否有助于复杂解剖结构的概念化。材料和方法:我们纳入了 5 个标本,由 200 名一年级医学生进行评估,在年龄和性别匹配后,采用系统随机法将其分为实验组(100 人)和对照组(100 人)。实验组使用 VI3DM 作为干预性学习资源,而对照组则使用二维照片作为传统学习资源,进行 30 分钟的自主学习。学员在学习前后填写了一份问卷,以评估他们对解剖标本的外部特征、附件和关系的了解程度。结果显示与对照组相比,实验组在后测试中对所有 5 个标本的得分都有显著提高(p 结论:VI3DM 能够帮助学生对解剖标本的外部特征、附着物和关系进行概念化:VI3DM 有助于对解剖结构的外部特征、附件和关系进行概念化。
