| Abstract: | The present teaching management adopts the arithmetical average method to analyze and evaluate students’ performances,which is difficult to truly reflect the states of students learning process.In this paper,based on a fully completed score-sheet of academic performance sampled from a class in a senior high school in Shanghai,the K-means approach is adopted to cluster the examination score,and a detailed analysis is subsequently conducted on the clustering results.The introduced approach proves more realistic and convincing,which can be used for more effective teaching and learning planning. |
| Keywords: | K-means algorithm clustering the academic performance the examination analysis |
