目的：评价在PBL和LBL相结合的模式中引入CBL的教学效果。方法：将本院麻醉学专业2014级两个本科教学班分别作为实验组（CBL＋PBL＋LBL组）与对照组（PBL＋LBL组）实施医用物理教学,采用问卷调查和期末考试相结合方式进行教学效果评价。结果：CBL＋PBL＋LBL教学效果明显优于PBL＋LBL。结论：在PBL和LBL相结合的模式中引入CBL是行之有效的。

英文摘要：

Purpose： To assess the teaching efficacy of combination of CBL, PBL and LBL compared to combination of PBL and LBL. Methods： Two 2014 undergraduate classes from the School of Anes- thesiology at our university were used as the experimental group （CBL＋PBL＋LBL） and control group （PBL＋LBL） respectively for the course of Medical Physics. A questionnaire and the final exami- nation were administered to determine the teaching efficacy. Results： Teaching efficacy in the experimental group is predominantly su- perior to that in the control group. Conclusion： combination of CBL, PBL and LBL is feasible and efficient.
