With the expansion of the scale of university,the number of students in colleges and universities also showed a growing trend,and various colleges and universities have also established their own teaching management system,such as school register management system,the academic performance management system and so on.Though equipped with specialized databases,these systems have been serving simply for data backup,enquiry and counting.Their failure to hunt for the related and potential information contained in the data and conduct comprehensive analysis correspondingly is a waste of the educational information resources.Data mining technology is a viable and effective method to solve this problem.Using data warehouse and data mining technology to analyze academic achievements and explore its internal and potential information is of great practical significance to the construction of the curriculum,specialty construction and improvement of teaching quality.In this paper,the data mining technology is applied to analyze academic achievements in our college,then the result can be used as a guide to make decision.The main contents of this paper are divided into the following aspects:First,it studies the achievements and learning information of each course and obtains the relevant initial data.Second,it cleanses,integrates,transforms and loads the original data sources extracted from the academic achievements data management system,then designs and establishes data warehouse by using MS SQL Server 2008 R2 EE.Third,this paper uses the association rules mining,clustering and classification methods to analyze the teaching data,digs out the interesting rules,and finds out the inter-impacts among courses and the relationship between academic performance and learning behaviors/activities.Finally,it analyzes and compares different data mining methods,assesses their outcomes respectively so as to provide scientific reference for teaching managers to make decision.This paper expounds the concepts of data mining,as well as the theoretical foundation and analysis process about association rule mining,clustering rule mining and classification rule mining methods.It focuses on applying data mining technology to analyze academic achievements,taking advantage of the above three mining methods to analyze academic achievements sample of a group of students,and then drawing the corresponding conclusions.Firstly,through the analysis of the relevance between different course grades,some feasible suggestions can be provided for the arrangement of curriculum order.Secondly,the lack of traditional classification method for grades can be made up through the clustering analysis of course grades.Thirdly,by analyzing the factors that affect the academic achievements,there will be an useful reference for improving the course achievements as well as improving the teaching quality.
