The study is oriented to three key groups: experts, students and teachers, constructs multivariate indicators, selects subjective and objective empowerment methods, and establishes a fuzzy comprehensive evaluation model of the effectiveness of the blended English teaching model. Seventy-eight experts, 61 students and 45 teachers are invited to conduct the fuzzy comprehensive evaluation. Taking a blended English classroom as the evaluation object, the students were most satisfied with the teaching effect, with an overall excellent affiliation of 0.638. The experts also highly recognized it, with an excellent and good affiliation of over 91%. Teachers were more cautious in their evaluations, with a slightly higher percentage of good (37.3%) than excellent (34.5%). The blended teaching model V={Excellent, Good, Moderate, Pass, Poor}={0.520,0.302, 0.110, 0.053 ,0.015}, with a weighted score of 87.65, which is in the category of “Excellent”.
