| 摘 要： | 叙述了试卷难度的一种评估指标体系,讨论了几种组卷算法,提出了一种基于平衡策略的试题库组卷算法,该算法以题型、掌握要求等为约束条件对试题库进行小集合划分,根据试卷的整体难度给出各种题型难度系数的平衡点,并调整各类题型的难度系数向对应的平衡点逼近,以达到对试卷整体难度的控制,通过程序验证,该算法以较高的组卷效率实现了对试卷难度的控制.

| Abstract: | This paper narrated a kind of assessment index system of the difficulty of test paper and discussed on several kinds of generating paper algorithm,put forward a genarating paper algorithm based on balance strategy.This algorithm divided the test database into small collection considering test types,mastering requirement as constraint conditions.And it gave out the balance point of difficulty coefficient of various test types according to overall ditticulty,adjusted the difficulty coefficient to approach their corresponding balance point.By program verification,this algorithm realized the control of the test difficulty at a higher efficiency. |
