摘要
通过分析高校统考课程成绩对高校教学进行分析决策的重要价值,以计算机基础统考课程成绩为实例,建立一个基于高校统考课程成绩的数据仓库模型。该成绩数据仓库不仅综合分析学生的总得分,而且将试卷难度和题型得分也做深入分析,分析结果不仅能让教学管理者了解到学生成绩波动趋势,而且可以更详细地知道成绩波动的原因所在,从而能帮助教学管理者更加科学快速地做出有效的决策,最终达到提高教学水平的目的。
To analyze the significance of the course grade of college-wide examination,takes grades of computer cultural foundation course as example,builds a data warehouse modeling based on the course grade of college-wide examination.The data warehouse not only comprehensive analyses the total score of students,but also depth analyses the paper difficulties and problem scores.The results can help teaching administrator to obtain the trends of scores,and find out the reason of the trends and there are helpful to administrator for making speedy,scientific and effectively decisions,so as to achieve the goal of enhancing the level of teaching.
