Research On Comprehensive Evaluation And Application Of Middle School Academic Achievement Based On Fuzzy Cluster Analysis

Examinations have always been an important means of teaching quality evaluation in middle school.Under the background of comprehensive promotion of education quality comprehensive evaluation reform in China,it is of great significance to explore new methods and strategies for comprehensive evaluation of middle school examination results.It is necessary for the school to carry out periodical achievement analysis and evaluation in time for the same grade students in the same middle school.In the research,fuzzy cluster analysis is applied to explore the value of academic performance data.In the end,the comprehensive evaluations of students' academic level,teacher's teaching level and head teacher's management level are realized.These evaluation conclusions have important reference value for middle school education decision-making.Firstly,dynamic clustering method based on fuzzy equivalence relation is used to generate fuzzy dynamic clustering graph for fuzzy cluster analysis.By establishing the mathematical model of data preprocessing,the achievement of periodical academic examination is integrated.Then,the standardized processing method of "Mean Normalization" is adopted to realize the transformation from original achievement to academic achievement.By comparison and demonstration,the Euclidean distance method is determined as the construction method of fuzzy similarity matrix.By using the "Square Method" to calculate the transitive closure,the structure of the fuzzy equivalent matrix is realized.Finally,the fuzzy dynamic clustering diagram is generated according to different classification thresholds.Secondly,the clustering method based on similar "Cluster" is proposed,and the dynamic analysis of each data object in the fuzzy dynamic clustering graph is realized.By the group of objects with obvious similarity under different classification thresholds,the limitation of classification threshold is broken.Then,the rule of the data in the fuzzy dynamic clustering graph is revealed by the visual representation of the cluster cylindrical graph.Thirdly,according to the result of fuzzy clustering analysis,the comprehensive evaluation of "grade" and "leaning branch" is realized.Fourthly,based on the results of the analysis and comprehensive evaluation,the application exploration is made from the two aspects of class management and teaching management.The empirical research shows that the dynamic clustering method based on fuzzy equivalence relation is feasible and effective for the comprehensive evaluation of middle school academic achievement.The conclusions can effectively guide the education work of the school in the next academic stage.
