摘要

教育测试通常有一组由共同刺激(试题)连接的项目。在这样的设计中,项目之间产生的依赖关系称为testlet效应。特别是,定向测试效应(DTE)指的是一种递归影响,即对早期项目的反应可以积极或消极地影响后期项目的分数。本研究旨在引入一种创新的测量模型来描述多个多重评分的开放式项目之间的dte。通过仿真,我们发现:(1)Latent GOLD®可以准确地恢复项目和DTE参数,(2)通过拟合标准项目反应理论模型忽略正(或负)DTE可能导致测试信度高估(或低估),(3)将一个测试小的多个项目折叠成一个超级项目仍然可以有效地消除DTE。(4)目前流行的多维度策略,即添加妨害因素来描述项目依赖关系,并不能充分解释DTE;(5)将提出的DTE模型拟合到包含妨害因素的测试数据中,可以观察到正的DTE,但没有更好的拟合。此外,利用所提出的模型,我们在真实的历史考试中证明了积极和消极的dte共存。

Modeling Directional Testlet Effects on Multiple Open-Ended Questions

Educational tests often have a cluster of items linked by a common stimulus (testlet). In such a design, the dependencies caused between items are called testlet effects. In particular, the directional testlet effect (DTE) refers to a recursive influence whereby responses to earlier items can positively or negatively affect the scores on later items. This study aims to introduce an innovative measurement model to describe DTEs among multiple polytomouslyscored open-ended items. Through simulations, we found that (1) item and DTE parameters can be accurately recovered in Latent GOLD®, (2) ignoring positive (or negative) DTEs by fitting a standard item response theory model can result in the overestimation (or underestimation) of test reliability, (3) collapsing multiple items of a testlet into a super item is still effective in eliminating DTEs, (4) the popular multidimensional strategy of adding nuisance factors to describe item dependencies fails to account for DTE adequately, and (5) fitting the proposed model for DTE to testlet data involving nuisance factors will observe positive DTEs but will not have a better fit. Moreover, using the proposed model, we demonstrated the coexistence of positive and negative DTEs in a real history exam.

期刊介绍: The Journal of Educational Measurement (JEM) publishes original measurement research, provides reviews of measurement publications, and reports on innovative measurement applications. The topics addressed will interest those concerned with the practice of measurement in field settings, as well as be of interest to measurement theorists. In addition to presenting new contributions to measurement theory and practice, JEM also serves as a vehicle for improving educational measurement applications in a variety of settings.
