Abstract:

Objective To explore the value of problem-based learning (PBL) method in clinical teaching of brain arteriovenous malformations surgical treatment. Methods A total of 30 postgraduates in Neurosurgery Department at Beijing Tiantan Hospital, Capital Medical University were randomized into PBL group and traditional lecture-based learning (LBL) group. After the course, the postgraduates in two groups took examination of basic theoretical knowledge, case analysis and operative treatment strategies. Examination scores were compared between the two groups. Results Compared with the LBL group, the performance in theoretical knowledge tests in PBL group was lower, which had no significant difference (P =0.51); however, the scores for case analysis and operative treatment strategy analysis of PBL group were significantly higher than that of the LBL group (P <0.001). Conclusion The PBL teaching model is better for teaching in brain arteriovenous malformations surgical treatment. It can effectively improve the abilities of case analysis and operative treatment strategy analysis.

摘要：

目的 探讨以问题为基础教学（problem based learning，PBL）在脑动静脉畸形外科临床教学中的应用 价值。 方法 选取首都医科大学附属北京天坛医院神经外科轮转的研究生30例，随机分为实验组和对照 组各15例，分别采用PBL教学和以授课为基础的教学法，对两组学生进行基础知识、病例分析和手术 治疗策略分析测试，比较两组的测试成绩。 结果 实验组与对照组相比较，基础理论知识考试成绩有降低趋势，但差异无显著性（P =0.51）； 病例分析考试成绩（P <0.001）和手术治疗策略分析（P <0.001）较对照组显著增高。 结论 PBL教学法是适合脑动静脉畸形临床教学的有效方法，有助于培养研究生的病例分析能力和 手术治疗策略分析能力。
