With economic globalization and the informatization of social life, English has become a language extensively used around the globe. The research on the evaluation of English teaching quality is of crucial practical significance and theoretical value. Hence, student evaluation form for the college English classroom teaching quality that has been evaluated and has good reliability is used in this paper to expound the principles of the triangular fuzzy number evaluation method and the range method based on the analytic hierarchy process (AHP). Examples are used to analyze the differences between the two methods as well as their advantages and disadvantages. The comprehensive evaluation result of the teaching quality evaluation of a teacher by using the range method is excellent (85.500 points), and the comprehensive evaluation result by using the triangular fuzzy number method based on the analytic hierarchy process is good (64.818 points). The results show that the range method is better for the comprehensive evaluation of teachers' teaching quality. The statistical analysis results suggest that there are differences between the two methods in the evaluation of the classroom teaching quality in colleges and universities (t = 11.197, P < 0.0001). In the evaluation of the teaching quality by using the triangular fuzzy number evaluation method based on the analytic hierarchy process, the non-linear and fuzzy features of evaluation factors are taken into consideration comprehensively. The weight values of various evaluation indexes are calculated scientifically. The qualitative and quantitative evaluations are combined to obtain the evaluation result of the classroom teaching quality of teachers more objectively, which is of great significance in the practical teaching quality evaluation process.
