| Abstract: | K-means clustering algorithm is an indirect clustering algorithm, which is based on comparability measurement of sample. We apply the approach of K-means clustering algorithm to analyze teaching quality of teacher, and select appropriate k. This method achieves to combine the evaluation of quantification and that of qualification, to realize the evaluating level, and to offer the reliable basis for confirming the evaluation index in the future. |
