摘要
给出了一种依据试卷区分度确定算法参数的智能组卷难度正态分布算法。实例表明,相对于目前的通过设定组卷难度区间的概率和为1来确定算法参数,生成的试卷更好地体现了组卷难度分布设计所要求的试卷对不同考生的知识能力的区分和鉴别的考核要求。
A difficulty normal distributing algorithm for an intellectual test sheet generating system, which takes the algorithmic parameter based on the differentiability of test paper is proposed in this paper.The examples show that the algorithm has better ability to differentiate examinee than the difficulty normal distributing algorithm, it assumes that the summation of probabilities is 100 percent within the range of the difficulty distribution to take the algorithmic parameter.
