| 摘 要： | 允许题目检查能够促进计算机化自适应测验(CAT)在实际中的应用。在不影响能力估计精度和测验公平性的前提下, 允许CAT题目检查能够缓解考生考试焦虑, 减少无关因素引起的测量误差。区块题目袋方法是连续区块方法与题目袋方法的结合, 不仅能允许CAT题目检查, 还能够弥补题目袋方法的不足。研究结果表明：(1)合理作答策略下, 区块题目袋方法的估计精度在低能力水平上要优于题目袋方法; (2)在应对类似Wainer作答策略时, 区块题目袋方法的估计精度在所有能力水平上均优于题目袋方法。(3)随着区块数的增加, 区块题目袋方法的能力估计精度越接近无修改的基线水平。

| Abstract: | Most computerized adaptive testing (CAT) do not allow examinees to review items because it will drastically decrease measurement precision and bring about extra cheating strategies (Wainer, 1993; Wise, 1996). Allowing item review is essential to make CAT comparable with traditional tests. It also matters in application. Item review enables examinees to correct mistakes due to carelessness, which can further improve the precision of ability estimation. No such option may cause some negative consequences for their overall performance especially in high-stake examinations, such as tension or anxiety (Vispoel, Henderickson, & Bleiler, 2000). Therefore, it is worth trying if allowing item review could alleviate problems mentioned at the beginning (Wise, 1996; Vispoel, 2000, 2005). |
