虽然“互联网 + 支教”规模正在逐渐扩大,但一直缺乏科学全面的评价体系来及时反馈其教学效果,本文从能力提升、情感态度与道德培育、身心健康共三个方面选取了12个指标,同时基于DEMATEL法计算各指标权重来建立云支教培养效果评价体系,最后根据DEMATEL法计算得出的结果对优化云支教的培养路径提供建议。Although the scale of “Internet + volunteer teaching” is gradually expanding, there has been a lack of a scientific and comprehensive evaluation system for timely feedback on its teaching effect. This paper selects 12 indicators from three aspects: ability improvement, emotional attitude and moral cultivation, and physical and mental health, and calculates the weights of each index based on the DEMATEL method to establish an evaluation system for the training effect of cloud volunteer teaching, and finally provides suggestions for optimizing the training path of cloud volunteer teaching according to the results calculated by the DEMATEL method.
