半翻转课堂结合知识点拍卖学习法在口腔黏膜病学教学中的应用

目的 探究半翻转课堂结合知识点拍卖学习法在口腔医学生理论授课中的应用与成效。方法 以中山大学光华口腔医学院四个年级本科生为研究对象，两个年级（n=198）采用半翻转课堂结合知识点拍卖学习法进行授课，另外两个年级（n=172）作为对照班，进行常规课堂教学。用课堂测验比较两个班级对重难点的掌握情况，并采用问卷评分调查两个班对课堂效果的反馈。采用SPSS 22.0进行独立样本t检验。结果 试验班课堂测验的平均得分高于对照班[（88.51±11.02） vs. （80.40±8.53）]。问卷结果显示，试验班学生对课程的兴趣、知识点理解与吸收、课堂满意度以及对章节内容的掌握情况，明显高于对照班[（7.28±1.51） vs. （9.10±0.73）；（6.92±1.44） vs. （8.69±1.62）；（6.09±1.87） vs. （7.61±1.46）；（6.40±1.04） vs. （7.70±0.86）]。结论 半翻转课堂结合知识点拍卖学习法具有创新性且教学效果明显，值得推广应用至各临床学科的理论授课中。

Application of semi-flipped classroom combined with the knowledge point auction learning method in teaching of oral mucosa diseases

Objective To explore the application of the semi-flipped classroom combined with knowledge point auction learning method in the theoretical teaching among stomatological students and its effectiveness.Methods Undergraduates from four classes at Guanghua School of Stomatology, Sun Yat-Sen University were taken as research subjects. Students from two classes (n=198) were taught using the semi-flipped classroom combined with the knowledge point auction learning method, while students from the other two classes (n=172) were taught with the regular classroom teaching method as controls. Classroom quizzes were used to compare the two classes'' mastery of important and difficult points, and a questionnaire was used to investigate students'' feedback on the class outcomes. SPSS 22.0 was used for the independent samples t-test.Results The mean test score of the experimental class was higher than that of the control class (88.51±11.02 vs. 80.40±8.53). The results of the questionnaire showed that students'' interest in the course, comprehension and absorption of knowledge points, degree of satisfaction with the class, and mastery of the contents in sections in the experimental class were significantly higher than those in the control class (7.28±1.51 vs. 9.10±0.73, 6.92±1.44 vs. 8.69±1.62, 6.09±1.87 vs. 7.61±1.46, 6.40±1.04 vs. 7.70±0.86 ).Conclusions The semi-flipped classroom combined with the knowledge point auction learning method is innovative and achieves good teaching outcomes. It holds promise for wider use in the theoretical teaching of various clinical subjects. To explore the application of the semi-flipped classroom combined with knowledge point auction learning method in the theoretical teaching among stomatological students and its effectiveness.
