Methods Totally eight classes were randomly assigned to the lecture based learning (LBL) group (n=4) and PBL group (n=4). The examination scores, questionnaire, and seminars were used to evaluate the teaching effectiveness. SPSS 11.5 software was used for statistical analysis. Results More than 50% of students in each group believed that the teaching method of PBL could activate learning enthusiasm and interest, improve problem analysis and independent study abilities. There were significant differences between the two groups in terms of comprehensive analysis, learning efficiency, digesting the contents of study and strengthening the teacher-student communication, and whether or not to perform PBL teaching. Apart from single choice questions, other types of examination questions and total scores have significant differences. Conclusions The PBL teaching model can effectively train undergraduateclinical thinking, cultivate the abilities of deconstructing problem, comprehensive analysis, literature retrieval, language expression, exploration innovation; and overall improve the teaching quality of evidence based medicine.Key words Problem-Based Learning; Evidence-Based Medicine; Teaching基金项目:兰州大学循证医学中心“循证医学本科生教学创新基金”(2008LDEBM-B)作者简介:田金徽,男(1978年~),讲师,以循证医学及医学信息检索为主要研究方向。Email: tjh996@*通讯作者,Email: yangkh2006@基于问题的学习(Problem-Based Learning,简称PBL),是在一定的情境中构建问题,让学生以小组的形式共同解决问题,并在该过程中完成知识的形成与整合。与传统教学模式(Lecture Based Learning,简称LBL)相比,PBL将“以教师为中心,学生被动学习模式”转变为“以学生为中心,学生主动学习模式”,激发了学生学习的兴趣和热情,增加了获得大量应用知识的机会,培养了学生掌握并运用知识和与他人相处的能力,提高了分析解决问题的技能,学习了隐含于构建问题背后的学科知识[1-3]。目前,PBL教学模式已在国外多所院校中推广、应用、修正和发展,并取得了良好的成效[4]。在我国,PBL教学模式处于起步阶段,中国医科大学、北京大学医学部、第四军医大学等学校已经开展了PBL教学试验,收到了良好的效果。为了探讨PBL教学模式在循证医学教学中应用的可行性及效果,我们在2005级临床医学专业1~8班循证医学教学中进行对比研究,为提高教学质量,深化教学改革,转变中国循证医学杂志 2009, 9(4): 392~395
