基于虚拟仿真技术辅助的CBL-PBL联合教学模式在脑血管介入疑难病例教学中的应用研究
Application of virtual simulation technology-assisted CBL-PBL integrated teaching model in the teaching of complex cerebrovascular intervention cases
目的 探索基于虚拟仿真技术的案例教学法(case-based learning,CBL)与问题导向教学法(problem-based learning,PBL)联合教学模式在脑血管介入疑难病例教学中的实践效果,评估其对临床思维能力、学习满意度、团队合作能力及长期学习效果的影响。 方法 采用随机对照研究设计,选取2023年12月—2025年3月在郑州大学第一附属医院全年接受培训的住院医师和规培医学生共120名作为研究对象,按1∶1分为对照组(n=60)和试验组(n=60)。对照组采用传统讲授教学;试验组在CBL-PBL联合教学基础上,引入虚拟现实脑血管介入模拟系统及在线交互式案例推演平台,开展情境化教学。教学周期结束后比较两组在临床思维能力、学习满意度、团队合作与沟通能力以及1个月后的知识保持与迁移水平。 结果 教学结束后,试验组学生的临床思维能力评分高于对照组(P<0.001),满意度总评分及各主要维度均优于对照组(P<0.05);团队合作小组互评得分亦更高(P<0.001),但教师评分差异无统计学意义(P>0.05)。随访测试显示试验组学生的知识保持水平仍高于对照组(P<0.001),但两组成绩下降幅度差异无统计学意义(P>0.05)。 结论 基于虚拟仿真辅助的CBL-PBL联合教学模式能够有效提升脑血管介入疑难病例教学效果,有助于培养学员的临床思维、合作沟通能力及知识迁移能力,具有较高的应用价值和推广前景。
Objective To evaluate the practical effectiveness of a teaching model that integrates case-based learning (CBL) and problem-based learning (PBL) with virtual simulation technology in the teaching of complex cerebrovascular intervention cases. The study assessed its impact on clinical reasoning skills, learning satisfaction, teamwork abilities, and long-term knowledge retention. Methods A randomized controlled trial was conducted with 120 resident physicians and standardized training medical students who received training at the First Affiliated Hospital of Zhengzhou University from December 2023 to March 2025. Participants were randomly assigned to either the control group (n=60) or the intervention group (n=60) in a 1∶1 ratio. The control group received traditional lecture-based instruction, while the intervention group engaged in a CBL-PBL integrated teaching model enhanced with a virtual reality cerebrovascular intervention simulation system and an interactive online case-based learning platform to create immersive clinical learning scenarios. At the end of the teaching period, both groups were evaluated on clinical reasoning ability, learning satisfaction, teamwork and communication skills, and knowledge retention and transfer one month later. Results After the teaching intervention, the intervention group showed significantly higher clinical reasoning scores than the control group (P<0.001). Overall satisfaction and scores across all satisfaction dimensions were significantly higher in the intervention group (P<0.05). Peer-assessed teamwork scores were also significantly higher (P<0.001), although instructor-assessed scores showed no significant difference (P>0.05). Follow-up testing revealed that knowledge retention in the intervention group remained significantly higher than in the control group (P<0.001), though the rate of score decline over time did not differ significantly between groups (P>0.05). Conclusion The virtual simulation-assisted CBL-PBL integrated teaching model significantly enhances the instructional effectiveness for complex cerebrovascular intervention cases. It contributes to the development of clinical reasoning, collaboration, and knowledge transfer skills among trainees and demonstrates strong potential for broader implementation in clinical education.
