In this study, the questionnaire survey, diversified classroom teaching, and multivariate evaluation are carried out on college students of non-English majors based on the Roche multiway tree clustering method. The SPSS statistical software is used for statistical analysis. The results show that Roche multiway tree cluster distribution of non-English major college students is at a medium level. There is no significant correlation between the comprehensive English performance and the overall Roche multiway tree clustering, and there is a low positive correlation between Roche multiway tree clustering and English listening. Studies have suggested that in comprehensive English classroom teaching, teachers should pay attention to the weak intelligence of students, teach students according to their intelligence difference, build a diversified classroom teaching evaluation model, and promote the all-round development of student intelligence.
