摘要

本文引入了一种子测试分层诊断分类模型(Testlet hierarchical diagnostic classification model,TH-DCM),将属性分层和项目捆绑考虑在内。参数估计采用了期望最大化算法和解析降维技术。研究人员进行了一项模拟研究,以评估所提出模型在不同条件下的参数恢复情况,并将 TH-DCM 与测试子高阶 CDM(THO-DCM;Hansen, M. (2013)。用于认知诊断的分层项目反应模型(未发表的博士论文)。UCLA; Zhan, P., Li, X., Wang, W.-C., Bian, Y., & Wang, L. (2015).多维试题效应认知诊断模型。Acta Psychologica Sinica, 47(5), 689. https://doi.org/10.3724/SP.J.1041.2015.00689)。结果表明:(1) 忽略大的小测验效应会恶化参数恢复;(2) 在大多数条件下,假设每个小测验内的小测验效应相等的多维小测验效应认知诊断模型与假设小测验效应不相等的小测验效应认知诊断模型表现一样好;(3) 联合属性分布的错误规范对参数恢复有不同程度的影响;(4) 在某些层次结构下,THO-DCM似乎是TH-DCM的稳健替代品。为了说明问题,还分析了一组真实数据。

A Testlet Diagnostic Classification Model with Attribute Hierarchies.

In this article, a testlet hierarchical diagnostic classification model (TH-DCM) was introduced to take both attribute hierarchies and item bundles into account. The expectation-maximization algorithm with an analytic dimension reduction technique was used for parameter estimation. A simulation study was conducted to assess the parameter recovery of the proposed model under varied conditions, and to compare TH-DCM with testlet higher-order CDM (THO-DCM; Hansen, M. (2013). Hierarchical item response models for cognitive diagnosis (Unpublished doctoral dissertation). UCLA; Zhan, P., Li, X., Wang, W.-C., Bian, Y., & Wang, L. (2015). The multidimensional testlet-effect cognitive diagnostic models. Acta Psychologica Sinica, 47(5), 689. https://doi.org/10.3724/SP.J.1041.2015.00689). Results showed that (1) ignoring large testlet effects worsened parameter recovery, (2) DCMs assuming equal testlet effects within each testlet performed as well as the testlet model assuming unequal testlet effects under most conditions, (3) misspecifications in joint attribute distribution had an differential impact on parameter recovery, and (4) THO-DCM seems to be a robust alternative to TH-DCM under some hierarchical structures. A set of real data was also analyzed for illustration.
