摘要
研究了在线测评系统的策略,重点介绍了抽题组卷策略,提出了动态确定题目难度系数的算法和随机组卷算法模型;在线评估是根据所做题目的知识点和历史记录,组织并生成个性化的学习计划,引导和督促学生学习。按照研究的策略,在J2EE平台上进行了设计,该文还介绍了系统所用的基于J2EE的主要技术。
This paper researches the strategy of online test-evaluating system,and instroduces the strategy of extracting and assembling subject,and brings forward dynamic algorithms of confirm difficulty coefficient and model of random assembling subject.Evaluating strategy is organizing and forming a individual plan according to knowledge point of worked subject and history records.The plan can lead the student study.The system is designed base on J2EE in term of above stragegy.This paper also introduces the main technology based on J2EE.
