中文摘要 | 采用计算机模拟程序对允许检查并修改答案的计算机化自适应测验(CAT)进行研究,并采用新的评分方式对付Wainer策略。结果表明:综合考虑被试的两次作答信息可以得到更精确的能力估计值。大部分被试进行了修改,只有少部分答案被修改,在被修改的答案中大部分是由错误改为正确;综合Wainer策略 CAT的后验分布期望值(EAP)和极大似然估计值(MLE)可以“粗糙”对付Wainer策略。 |
英文摘要 | In the past decade, some paper-and-pencil (P&P) tests have been replaced by computerized adaptive testing (CAT) within many large-scale standardized testing programs. However, many researches and applications on CAT had limitations because most of the CAT did not allow examinees to review and change their answers. Among the operative CAT applications, there was only one that incorporated item review. Not allowing examinees to review and change their answers would result in test pressure and affe |
