PBL 与 3D 打印数字化技术在脊柱外科教学中的应用
Application of PBL and 3D Printing Digital Technology in Spine Surgery Teaching
目的 探究问题驱动教学法(Problem-based Learning,PBL)联合 3D 打印技术、数字化工具及人工智能反馈系统,对脊柱外科临床教学中医学硕士研究生理论掌握、临床技能、综合素质及教学认可度的影响,构建“数字化—素质化—智能化”三位一体新型教学体系。 方法 选取2023年3月— 2025年3月在脊柱外科轮转的医学专硕68 名(分批次入组,每批次教学周期8 周),随机分为实验组与对照组各34名。对照组用传统教学,实验组加用PBL、3D打印、数字化平台及AI反馈系统,比较两组理论成绩、临床技能、综合素质及教学评价得分。 结果 实验组理论成绩(82.56±5.32)分、临床技能(85.36±4.89)分、综合素质(88.62±4.15)分、教学评价(35.28±3.15)分,均显著高于对照组(75.12±6.18)分、(73.25±5.67)分、(76.35±5.23)分、(26.75±4.23)分,差异有统计学意义(P<0.05)。 结论 该新型教学模式可提升专硕多方面能力,为脊柱外科临床教学改革提供有效路径,值得推广。
Objective To explore the impact of the PBL teaching method combined with 3D printing technology, digital tools, and artificial intelligence (AI) feedback systems in the clinical teaching of Spinal Surgery on postgraduate students’ theoretical knowledge, clinical skills, comprehensive competencies, and acceptance of the teaching, and construct a “digital-qualitative-intelligent” three-in-one teaching system. Methods A total of 68 professional degree medical postgraduates rotating in the Department of Spinal Surgery of our hospital from March 2023 to March 2025 were enrolled (in batches; each teaching cycle lasted 8 weeks) and randomly assigned to the experimental group and the control group (n=34 each). The control group received traditional teaching, while the experimental group received an integrated mode combining PBL, 3D printing, a digital teaching platform, and an AI feedback system. Theoretical knowledge, clinical skills, comprehensive competency, and teaching evaluation scores were compared between the two groups. Results The experimental group achieved significantly higher scores in theoretical knowledge (82.56±5.32), clinical skills (85.36±4.89), comprehensive competency (88.62±4.15), and teaching evaluation (35.28±3.15) than the control group (75.12±6.18, 73.25±5.67, 76.35±5.23, and 26.75±4.23, respectively), with all differences being statistically significant (P<0.05). Conclusion This new teaching mode enhances various competencies of professional master’s students and provides an effective pathway for reforming clinical education in Spinal Surgery, making it worthy of promotion.
