题库设计与成卷系统

Question-base design and paper-generating system

探讨了题库设计过程中应该考虑的诸要素 ,给出了一个基于Foxpro平台的题库与成卷系统 .该系统以本科高等数学的考试为背景 ,现有试题 50 0余道 .就题库中的每道试题 ,引入了试题难度、区分度等主要量化指标 .基于这一已有题库的试卷生成系统 ,可以交互方式依用户要求在题库中检索试题 ,并最终生成一张试卷 .该系统可以保证试题选取的随机性和无重复性 ,试运行良好 .

Question-base is a very useful application sample of database technique. But designing a question-base is concerned with many aspects and difficulties, some of which are out of the range of computer science. This paper discusses some elements in question-base design and gives out a paper-generating system based on a existed question-base. This system is running well now.
