【摘要】 随着计算机网络技术的迅猛发展,构建在计算机网络环境上的出卷系统也被越来越多的单位和部门所使用.考试从传统的纸质试卷作业变成计算机作业已经成为不可抗拒的潮流.在智能出卷系统中,有一个重要的参数就是难度系数.难度系数的准确性关系到整个试卷出题难度的准确性.本文提出了一种对试题出卷系统中的难度系数的自适应调节方法.利用统计规律和人工经验相结合的方式对题目的难度系数进行调节,使得出卷系统能够生成不同难度级别的试卷,以满足不同用户的需求.更多还原

【Abstract】 With the rapid development of computer and network technology,examination paper systems are used by more and more organization and departments.It’s inevitable that exam by computer will replace exam by paper.Coefficients of difficulty plays an important role in smart examination paper system.This paper presents an adaptive regulating algorithm to coefficients of difficulty for an examination designing system.The statistical rule in combination with human experience is used to adjust the coefficient of difficulty for individual test question so that the examination designing system can generate papers with various coefficients of difficulty in order to meet diverse requirements of test takers.更多还原
