In this paper, the approach of fuzzy clustering is applied to analyze the teaching quality of teachers, which comprises selecting appropriatesimilar coefficient, setting up fuzzy similar matrix, and making classification with dynamic clustering. This method could therefore lead to the combination of the evaluation of both quantification and qualification, revealing the performance of the teachers objectively.
