摘　　要：目的研究传统讲授教学、线上教学、线上线下混合式教学3种模式在临床营养学选修课教学中的应用效果,评价混合式教学模式的优势。方法以四川大学2019年-2020年秋季、2019年-2020年春季和2020年-2021年秋季3个学期共316名选课学生为研究对象,线下组69人,采用传统讲授教学模式;线上组133人,利用学习通软件,采用完全线上授课教学模式;线上线下混合组114人,采用传统讲授教学模式并增加学习通软件线上教学内容。分析比较各组期末考试成绩和问卷调查满意度。考试成绩以中位数(下四分位数,上四分位数)表示。结果线上组[男:88.0(85.0,93.0)分;女:91.0(86.0,94.0)分]及线上线下混合组成绩[男:90.0(83.0,94.0)分;女:91.0(87.5,95.0)分]均明显高于线下组[男:83.0(77.0,89.0)分;女:77.5(67.0,87.0)分](P<0.001)。与线下组和线上组相比,女生对线上线下混合式教学模式的满意度更好(P<0.01)。结论线上线下混合式教学模式能显著提高学生成绩和学习积极性,可为推动临床营养学选修课课程改革提供依据。Objective To compare the effectiveness of three teaching modes,namely traditional teaching,online teaching,and online and offline blended teaching,in the teaching of the clinical nutrition elective course,and to evaluate the advantages of the online and offline blended teaching mode.Methods A total of 316 students taking the clinical nutrition elective course at Sichuan University in one of the three semesters,Fall 2019-2020,Spring 2019-2020,and Fall2020-2021,were enrolled as the study population.In the offline group,69 students used the traditional teaching mode;in the online group,133 students used the online teaching mode through Chaoxing Xuexitong application;in the online and offline blended teaching group,144 students used the traditional teaching mode combined with the online teaching.The final exam results and questionnaire satisfaction of the three groups were analyzed and compared.The exam results were presented as median(lower quartile,upper quartile).Results The exam results of the online group[males:88.0(85.0,93.0);females:91.0(86.0,94.0)]and the online and offline blended group[males:90.0(83.0,94.0);females:91.0(87.5,95.0)]were significantly higher than those of the offline group[males:83.0(77.0,89.0);females:77.5(67.0,87.0)](P<0.001).Compared to the offline teaching mode and online teaching mode,the female students’satisfaction with the online and offline teaching mode was better(P<0.01).Conclusion The online and offline blended teaching mode can significantly improve students’performance and learning motivation,and provide a basis for promoting the reform of the clinical nutrition elective course.
