混合教学模式下卫生统计学课程的成绩分析与评价
Performance Analysis and Evaluation of a Health Statistics Course in a Blended Teaching Model

目的：通过分析预防医学专业卫生统计学课程成绩，探讨混合教学模式对卫生统计学教学效果的影响。方法：采用形成性评价方式，得到预防医学专业2018级和2019级学生过程性评价成绩、总评成绩和期末成绩，进行对比分析。结果：期末考试成绩的均值和优秀率在两个年级的差异无统计学意义(t = 0.520, P > 0.05; ？？² = 0.637, P > 0.05)，2018级的过程性评价成绩和总评成绩均高于2019级(t = 6.295, P < 0.05; t = 2.316, P < 0.05)，2018级的过程性评价成绩优秀率、总评成绩及格率均高于2019级(？？² = 10.789, P < 0.05; ？？² = 4.433, P < 0.05)。结论：混合教学模式在提升学生学习效果上有积极作用，对提升教学质量具有显著意义，并为提升卫生统计学教学效果指明了方向。
Objective: To explore the influence of mixed teaching mode on the teaching effect of health statistics by analyzing the results of health statistics course in preventive medicine. Methods: Formative evaluation was used to obtain the process evaluation grades, overall evaluation grades and final grades of preventive medicine majors in the grades of 2018 and 2019, which were compared and analyzed. Results: The difference between the mean and excellence rate of final examination scores in the two grades was not statistically significant (t = 0.520, P > 0.05; ？² = 0.637, P > 0.05), and the process evaluation scores and overall assessment scores of Grade 2018 were higher than those of Grade 2019 (t = 6.295, P < 0.05; t = 2.316, P < 0.05), and the process evaluation grades of the class of 2018 were higher than those of the class of 2019 in terms of the excellent rate and the passing rate of the overall assessment (？？² = 10.789, P < 0.05; ？？² = 4.433, P < 0.05). Conclusion: The blended teaching mode has a positive effect on enhancing students’ learning, which is significant for improving teaching quality and points out the direction for improving the effectiveness of teaching health statistics.
