BACKGROUND: Traditional cadaveric dissection is declining whilst plastinated and three-dimensional printed (3DP) models are increasingly popular as substitutes to the conventional anatomy teaching and learning methods. It is unclear about the pros and cons of these new tools and how they impact students' learning experiences of anatomy including humanistic values such as respect, care and empathy. METHODS: Ninety-six students' views were sought immediately after a randomized cross-over study. Pragmatic design was used to investigate the learning experiences of using plastinated and 3DP models of cardiac (in Phase 1, n = 63) and neck (in Phase 2, n = 33) anatomy. Inductive thematic analysis was conducted based on 278 free text comments (related to strengths, weaknesses, things to improve), and focus group (n = 8) transcriptions in full verbatim about learning anatomy with these tools. RESULTS: Four themes were found: perceived authenticity, basic understanding versus complexity, attitudes towards respect and care, and multimodality and guidance. CONCLUSIONS: Overall, students perceived plastinated specimens as more real and authentic, thus perceived more respect and care than 3DP models; whereas 3DP models were easy to use and prefered for learning basic anatomy.
背景:传统的尸体解剖正在减少,而塑化和三维打印(3DP)模型作为传统解剖教学和学习方法的替代品越来越受欢迎。目前尚不清楚这些新工具的优缺点,以及它们如何影响学生的解剖学习体验,包括尊重、关怀和同理心等人文价值观。
方法:在一项随机交叉研究后,立即征求了 96 名学生的意见。采用实用设计研究了使用心脏(第 1 阶段,n=63)和颈部(第 2 阶段,n=33)解剖塑化和 3DP 模型的学习体验。基于 278 条关于使用这些工具学习解剖的自由文本评论(与优势、劣势、改进之处相关)和焦点小组(n=8)的完整逐字记录,进行了归纳主题分析。
结果:发现了四个主题:感知的真实性、基本理解与复杂性、对尊重和关怀的态度,以及多模态和指导。
结论:总的来说,学生认为塑化标本更真实、更逼真,因此比 3DP 模型更受尊重和关怀;而 3DP 模型易于使用,更适合学习基本解剖。
