摘　　要：目的探索合理应用新教学技术,建立适合临床医学本科生《医学统计学》实验教学的新方法。方法从西安医学院2016级18个临床医学本科班中抽取临床1604班(n=62)和全科1618班(n=54)为研究对象。1604班为试验组(A组),采用"传统演示+混合"式教学法;1618班为对照组(B组),采用传统演示法。从满意度问卷、教师自评和成绩3方面进行效果评价。用SPSS 22.0进行卡方检验、t检验和秩和检验。结果学期末两组对统计学的价值认知比上课前均有提高,且试验组[93.5%(58/62)]高于对照组[68.5%(37/54)](χ^(2)=12.20,P<0.001);试验组的总体满意度(Z=-7.05,P<0.001)、上课方式满意度(Z=-3.95,P<0.001)均高于对照组;两组对课程内容满意度差异无统计学意义(Z=-0.27,P=0.784);试验组有更多的学生认为实验课加深了对统计理论的理解(χ^(2)=26.87,P<0.001);在后4次实验课中,两组的后测均高于前测成绩,但试验组前、后测成绩均高于对照组;试验组软件操作成绩高于对照组(t=8.27,P<0.001);两组期末考试成绩差异无统计学意义(t=0.29,P=0.773)。结论"传统演示+混合"的实验教学符合现阶段医学本科生的学习规律和心理,能更好地提高学生对统计学的价值认知和满意度,尤其是混合式教学能更好地培养学生的团队合作、表达、分析和SPSS操作的能力。Objective To explore the application of new teaching techniques and establish a new model for experimental teaching of Medical Statistics for undergraduate students of clinical medicine.Methods We enrolled 2 classes of students from Xi'an Medical University as research objects,and they were randomized into study group(n=62)and control group(n=54).The study group received"traditional demonstration+blended"learning,while the control group only received traditional teaching.On the premise of balanced comparability,the effects of the two teaching patterns were evaluated from such three aspects as satisfaction questionnaire,teacher's self-evaluation and achievement.SPSS 22.0 was performed for chi-square test,t test and rank sum test.Results At the end of the semester,the value cognition of statistics in both groups was higher than before class,and the study group[93.5%(58/62)]was higher than that in the control group[68.5%(37/54)](χ^(2)=12.20,P<0.001).The overall satisfaction(Z=-7.05,P<0.001)and the satisfaction with teaching methods(Z=-3.95,P<0.001)of the study group were significantly higher than those of the control group,with no statistical difference in satisfaction with teaching contents between the two groups(Z=-0.27,P=0.784).More students in the study group thought that the experimental class deepened their understanding of statistical theory(χ^(2)=26.87,P<0.001).In the last four experimental classes,the post-test scores of both groups were higher than those of the pre-test,but the pre-test scores and post-test scores of the study group were higher than those of the control group.The performance of software operation in study group was higher than that in control group(t=8.27 P<0.001).There was no statistical difference in the final test scores between the two groups(t=0.29,P=0.773).Conclusion The"traditional demonstration+blended"learning is more in line with the students'learning pattern,and can better improve students'cognition and satisfaction of the statistics,especially can better cultivate students'te
