目的 探讨和评价3D打印技术制作个体化心脏病变三维立体模型,配合以问题为基础学习(problem based learning,PBL)教学的效果。方法 选取北京大学医学部临床医学专业2010级和2011级本科生、外科研究生共200人作为研究对象,以100名2011级学生作为实验组,100名2010级学生作为对照组。根据教学大纲要求,对实验组学生采用3D打印个体化心脏病变三维立体模型+多媒体配合PBL教学,对照组采用常规教具+多媒体配合PBL教学。学习结束后,分别对两组学生进行考核和问卷调查,评价教学效果。结果 实验组学生在理论知识、临床思维、学习能力、外科操作能力方面优于对照组学生,差异具有统计学意义(P<0.05)。结论 3D打印技术制作个体化心脏病变三维立体模型,配合PBL教学的模式,有助于加强对心脏病的学习和理解,获得了较好的教学效果,在医学教育方面有很好的应用前景。

Objective To explore and evaluate the teaching effect of the 3D printing technology applied for the PBL model in cardiac surgery clinical teaching.Methods 100 clinical medicine students of eight-year program of grade 2011was as the test group,and 100 clinical medicine students of eight-year program of grade 2010was as the control group. In test group, we introducedthe 3D printing technology to the PBL model in cardiac surgery clinical teaching.The traditional teaching aidswere applied for PBL model in control group. After the course,the teaching effect was evaluated by examination and questionnaire.Results Through the 3D printing technology teaching aids,the students adapted to clinical practice and training more quickly,mastered the key learning points and methods better than them in control group (P<0.05).Conclusions 3D printing technology applied for the PBL model is a promising method in cardiac surgery clinical teaching.
