摘要
为了有效地利用计算机来减轻教师的工作负担,使计算机能够从已有的试题库中自动组合相关试题形成试卷,提出基于难度系数的数学模型,利用正态分布的概率函数确定不同难度级别试题的最大分数,实现自动抽题的随机组卷的智能算法。
In order to reduce the teachers＇ burden, we use computers to form examination paper from the item pool. Designs the mathematical model based on the coefficient of difficulty, it uses the normal distribution function to the maximal score of different degree of difficulty question and realizes an algorithm of automatic test-question extraction.
