基于Web数据库的在线动态组卷

The Practice of Composing Test-Paper Dynamically Based on Web Database On-Line

网上“在线测试”是远程教学系统的重要组成部分 ,而实现网上测试的关键是探索一种高效而实用的动态组卷算法 .在开发“大学英语应试训练网站”、“基于 Internet的电子商务教学平台”的过程中 ,对网上在线测试子系统中的动态组卷进行了有益的尝试 .并在远程教学系统开发的过程中进行了动态组卷算法的优化实践 .

On-line Testing System' is an important component of 'Distant-learning System based on Internet'. Moreover, the key to realizng the testing is to explore a kind of algorithm that is dynamic, efficient and applied for composing test-paper. The author of this paper experimented with composing a dynamic test-paper in 'on-line testing subsystem' under the procedure of developing 'College English web-station for examinee' and 'Electronic Commerce teaching platform based on Internet'. This paper will introduce the process of optimizing algorithm about composing a dynamic test-paper in the course of developing distant-learning system.
