云模型是实现定性概念与定量表示之间不确定性转换的模型。将云模型理论用于模糊教学评价中,利用云变换计算隶属函数,结合模糊评价算法求出符合实际情况的评价等级。实验结果表明,将该方法用于对双语教学的评价,能够使评价结果更准确、更全面、更科学,从而有效提高教学的质量,并能改进教学的方法。 Cloud models are models that enable the transformation of uncertainty between qualitative concepts and quantitative representations. The cloud model theory is used in the fuzzy teaching evaluation, the membership function is calculated by cloud transformation, and the fuzzy evaluation algorithm is used to find out the evaluation grade according to the actual situation. Experimental results show that using this method to evaluate bilingual teaching can make the evaluation results more accurate, comprehensive and scientific, so as to effectively improve teaching quality and improve teaching methods.
