摘　　要：计算机化自适应测验(computerized adaptive testing,CAT)可以根据每一名考生的不同作答进行自适应选题,提高了测验精度.但高精度也伴随着高曝光风险,分层类项目曝光控制策略作为项目曝光控制的方法之一,是近年来曝光控制研究领域的热点.同时,反应时(RT)的收集是CAT的一大优势,RT对于测验的实施具有重要价值.该文综合介绍了传统的分层策略,并结合RT的分层策略探讨当前分层策略应用于CAT项目曝光控制中存在的问题及其未来研究方向.Computerized adaptive testing(CAT)can improve test accuracy by selecting items according to the responses so far of each examinee.However,high accuracy is also accompanied by high exposure risk,which may lead to item leakage,reduce test efficiency and endanger test security.Stratification item exposure control strategy,as one of the methods of item exposure control,is a hot spot in the field of exposure control research in recent years.At the same time,the collection of response time(RT)is a major advantage of CAT,and RT is of great value to the implementation of tests.The synthesis of traditional and combined RT tiered strategies are presented and the current problems and future research directions are discussed in the application of tiered strategies to CAT item exposure control.
