| 目的 探讨以问题为基础的学习（problem-based learning， PBL）结合传统教学在心电图诊断教学中的应用效果。方法 选取2011级临床医学专业80名学生为研究对象，随机分为常规组和研究组，常规组针对心电图诊断实施传统教学，研究组针对心电图诊断采用PBL结合传统教学，观察2组的教学效果。计量资料行独立样本t检验，采用均数±标准差（x±s）表示，计数资料采取χ2检验，以P＜0.05为差异有统计学意义。结果 研究组教师对学生的学习满意度为95.0%（38/40），常规组教师对学生的学习满意度为80.0%（32/40），2组满意度比较差异有统计学意义（P=0.001）。研究组学生对教学方法的满意度为100.0%（40/40），常规组学生对教学方法的满意度为87.5%（35/40），2组比较差异有统计学意义（P=0.000）。研究组学生的技能操作、理论知识和心电图分析能力的评分均明显高于常规组，差异有统计学意义（P=0.012、0.021、0.016）。结论 心电图诊断教学中将PBL与传统教学相结合的效果优于单独传统教学，能提高教学质量，值得推广。 |

| Objective To investigate the effect of problem-based learning（PBL） combined with traditional teaching in the teaching of electrocardiogram（ECG） diagnosis. Methods Totally 80 2011 grade clinical medicine students were enrolled and randomly divided into study group and regular group. Traditional teaching method was implemented in regular group while PBL com-bined with traditional teaching was applied in study group. Effect was observed；measurement data were analyzed by independent samples t test and were expressed as mean ± standard deviation x±s；enumeration data were analyzed by χ2 test. P<0.05 signifies statistical differences. Results Satisfaction degree of students towards teachers was 95.0%（38/40） in study group and was 80.0%（32/40） in regular group with statistical significances between two groups（P=0.001）. Satisfaction degree of students towards teaching method was 100.0%（40/40） in study group and was 87.5%（35/40） in regular group with statistical significances between two groups（P=0.000）. Operating skills， theoretical knowledge and ECG analysis capabilities scores were significantly higher in study group than in regular group with statistical differences（P=0.012， P=0.021， P=0.016）. Conclusions Implementing PBL teaching combined with traditional teaching can achieve significantly better teaching effect than traditional teaching， therefore it is worthy of application and promotion. |
