课程教学质量分析系统的研究与实现

Research and Implementation of Course Teaching Quality Analysis System

基于数据仓库的数据挖掘是涉及人工智能、机器学习和数据库等多学科的一个相当活跃的研究领域。随着技术发展,如何更好地将数据仓库和数据挖掘技术应用于教育领域,进行针对教学质量测评系统数据仓库、教学质量相关主题数据立方体的数据挖掘,已成为目前教育领域应用研究的重点问题。论文参照学校教务部门对教学质量的评价体系,重点研究以考试成绩为主线的课程教学质量的分析方案,以Delphi为开发平台设计和实现了一个"课程教学质量分析系统"。论文在介绍了对数据仓库、联机分析处理(OLAP)等相关概念之后;给出了课程教学质量分析系统的分析模型和数据模型的设计;展示了课程教学质量信息的联机分析处理结果。

Data Mining,based on Data Warehouse,is a quite active research field which deals with a wide range of disciplines including Ar tificial Intelligence,Machine Learning,and Database etc.Along with the development of techniques,how to apply the techniques of Data Mining and Data Warehouse to the education and implement the data mining on the data warehouse of the teaching quality evaluation sys tem and subject-related data cube has become the key question of application research in the current educational field.This paper focuses on the research of the grade-centered course teaching quality analysis scheme which references the teaching quality evaluation system ad opted by Educational Administration Office,designs and implements a"Course Teaching Quality Analysis System"based on Delphi.After briefly introducing the conception of Data Warehouse and OLAP,this paper describes the design of the analysis model and data model of the system,and shows the results of OLAP on information of course teaching quality analysis.
