应用德尔菲法和优序图法构建翻转课堂教学指标评价体系

Application of Delphi method and superiority chart in constructing the flipped classroom teaching index evaluation system

目的探讨使用德尔菲法和优序图法构建翻转课堂教学指标评价体系。方法采用德尔菲法进行专家咨询,采用优序图法计算翻转课堂教学评价体系中各指标的权重。采用SPSS 17.0软件对指标的重要性赋值进行统计分析。结果经两轮专家函询后,形成翻转课堂教学模式评价体系,一级指标3项,权重分别为(0.32,0.56,0.12);二级指标6项,权重分别为(0.45,0.55;0.56,0.44;0.55,0.45)、三级指标20项。结论德尔菲法是最常用的指标评价法,利用其对相关指标进行筛选和修正远优于其他数理学统计方法。在权重确定方面,优序图法相对于因子分析法,不需要建立判断矩阵,也不需要进行一致性检验,具有操作简单、省时省力的特点,值得推广。

Objective To explore the use of Delphi method and superiority chart to construct flipped classroom teaching index evaluation system.Methods Delphi method was applied to conduct expert consultation,and the superiority chart was used to calculate the weight of each index of the flipped classroom teaching evaluation system.SPSS 17.0 was used to statistically analyze the importance assignment of indicators.Results After two rounds of correspondence consultation,the evaluation system of flipped classroom teaching mode was established,with 3 first-level indicators with weights of(0.32,0.56 and 0.12);6 second-level indicators with weights of(0.45,0.55,0.56,0.44,0.55 and 0.45)and 20 third-level indicators.Conclusion Delphi method can not be substituted for other methods of mathematical statistics.In terms of weight determination,compared with analytic hierarchy process(ahp),the superiority chart does not need to establish judgment matrix,or to conduct consistency test.This method is simple to operate,time-saving and labor-saving,and is worthy of extensive promotion.
