线上教学效果量表的汉化及信效度检验

Translation and validation of the Chinese version Online Teaching Effectiveness Scale

目的 汉化修订线上教学效果量表并进行信效度检验,为高校开展线上教学效果评价提供适宜工具。方法 通过翻译、专家函询、预调查及文化调适等方法形成中文版线上教学效果量表,对435名大学生进行调查,分析量表的信效度。结果 中文版线上教学效果量表经过探索性因子分析提取展示、专业、促进及参与4个因子共10个条目,累积方差贡献率为89.023%;验证性因子分析最终模型中10个条目的因子载荷为0.446~0.936 (P<0.001);指标模型适配良好;量表总内容效度指数为0.967,条目内容效度指数为0.812~0.989;总量表Cronbach′s α系数为0.925,重测信度0.899。结论 中文版线上教学效果量表具有良好的信效度,可用于学生视角来评价教师线上教学效果的测评工具。

Objective To translate the Online Teaching Effectiveness Scale into Chinese,to test its reliability and validity,and to provide useful tool for evaluating online teaching effectiveness.Methods The Chinese version Online Teaching Effectiveness Scale(C-OTES) was formed through translation,expert consultation,pilot survey,and cultural adaptation,etc.Then 435 students were surveyed with C-OTES to test its reliability and validity.Results Such 4 common factors as display,professionality,promotion and participation,were extracted out of the 10-item C-OTES by exploratory factor analysis,and the cumulative variance contribution rate was 89.023%.Confirmatory factor analysis showed that the factor loading of 10 items ranged from 0.446 to 0.936(P<0.001),and the other model fit indexes were satisfactory.The content validity index(CVI) at the scale level was 0.967,and the CVI of each item ranged from 0.812 to 0.989.Cronbach′s α coefficient for the whole scale was 0.925.The test-retest reliability coefficient was 0.899.Conclusion C-OTES has good reliability and validity,and can be used as a tool to evaluate the teaching effect of online courses.
