Abstract


Aimed at student performance analysic of this section,only there is a huge database,but no in-depth anaylsis of the factors that lead to differences in student achievement,this pape designed and completed student performance analysis system.In this paper,the ID3 decision tree algorithm for the calculation of the shortcomings of overly complex was proposed based on rough set of centralized decision-making to improve the coordination of ID3 algorithm, and to improve the algorithm is applied to the student achievement analysis systems.After the improved ID3 algorithm is able to accurately tap out the hidden factors behind student achievement,and the calculation minus for fewer.This analysis system of student achievement and change the existing student management systems can only insert,delete,query and other simple operations situation.The use of data mining technology to solve the problems people have been confused fo school teachers,students and managers that can reference the data and conclusions,in order to improve the teaching aspects of the foundation.
