计算机自适应测试组卷方法策略与设计

Strategy and Design of Computer Adaptive Test Method for Paper Construction

计算机自适应测试(CAT)的组卷过程和方法与传统纸笔考试的组卷过程和方法有很大不同。CAT测试是进阶式的,每个进阶模块都分别要根据题目难度、区分度、猜度三参数情况,以及题目的知识点分布、能力层次等情况进行组卷。本文通过建立组卷数学模型,利用基于Web的ASP代码进行过程描述,以期达到较为理想的CAT组卷效果。

The difference is quite impressive between the progress and method of computer adaptive test （CAT） for paper construction and those of traditional written examination. The CAT is advanced, and each ad- vanced module can do paper construction based on three parameters--the difficulty, discrimination and surmise--of exam questions respectively, the knowledge point distribution and the level of student ability. This paper uses ASP code based on WEB to make the progress description by building a mathematical model and finally make a rela- tively ideal CAT paper construction effect that is expected.
