The present study tested the possibility of operationalizing levels of knowledge acquisition based on Vygotsky's theory of cognitive growth. An assessment tool (SAM-Math) was developed to capture a hypothesized hierarchical structure of mat...
Rasch Mixture Models for DIF Detection: A Comparison of Old and New Score Specifications [0.03%]
DIF检测的rasch混合模型：新旧分数规范的比较

Rasch mixture models can be a useful tool when checking the assumption of measurement invariance for a single Rasch model. They provide advantages compared to manifest differential item functioning (DIF) tests when the DIF groups are only w...

Differential item functioning (DIF) for an item between two groups is present if, for the same person location on a variable, persons from different groups have different expected values for their responses. Applying only to dichotomously s...

Many scales contain both positively and negatively worded items. Reverse recoding of negatively worded items might not be enough for them to function as positively worded items do. In this study, we commented on the drawbacks of existing ap...
A Direct Latent Variable Modeling Based Method for Point and Interval Estimation of Coefficient Alpha [0.03%]

A direct approach to point and interval estimation of Cronbach's coefficient alpha for multiple component measuring instruments is outlined. The procedure is based on a latent variable modeling application with widely circulated software. A...
Investigating Measurement Invariance in Computer-Based Personality Testing: The Impact of Using Anchor Items on Effect Size Indices [0.03%]

A popular method to assess measurement invariance of a particular item is based on likelihood ratio tests with all other items as anchor items. The results of this method are often only reported in terms of statistical significance, and res...

This report summarizes an empirical study that addresses two related topics within the context of writing assessment-illusory halo and how much unique information is provided by multiple analytic scores. Specifically, we address the issue o...
Multidimensional Classification of Examinees Using the Mixture Random Weights Linear Logistic Test Model [0.03%]
基于混合随机权重线性物流测试模型的被试多维分类方法研究

An essential feature of the linear logistic test model (LLTM) is that item difficulties are explained using item design properties. By taking advantage of this explanatory aspect of the LLTM, in a mixture extension of the LLTM, the meaning ...
Maximum Likelihood Item Easiness Models for Test Theory Without an Answer Key [0.03%]
无答案键情况下极大似然项目难度模型测试理论

Cultural consensus theory (CCT) is a data aggregation technique with many applications in the social and behavioral sciences. We describe the intuition and theory behind a set of CCT models for continuous type data using maximum likelihood ...
Anchor Selection Strategies for DIF Analysis: Review, Assessment, and New Approaches [0.03%]

Differential item functioning (DIF) indicates the violation of the invariance assumption, for instance, in models based on item response theory (IRT). For item-wise DIF analysis using IRT, a common metric for the item parameters of the grou...
