The application of data mining technology in analysis of college student´s performance

Data Mining is deeply data analysis method; it can take many goods to evaluate the high school students studying effectiveness. This paper take a high school computer department student´s information analysis as an example, according to the implementatation of data mining program, realized the whole process of classification and excavation of the data completely. The process includes making sure the Data Mining target, collecting the data, preprocessing data, classifying and generating the classification rule. ID3 is used to generate a decision tree and post-pruning method is used to pruning the tree. And the according to the decision tree, the classification rule is obtained. The results of Data mining can guide teaching scientifically and improve the quality of teaching.
