Paradoxical Results in Multidimensional Item Response Theory
In multidimensional item response theory (MIRT), it is possible for the estimate of a subject’s ability in some dimension to decrease after they have answered a question correctly. This paper investigates how and when this type of paradoxical result can occur. We demonstrate that many response models and statistical estimates can produce paradoxical results and that in the popular class of line...
متن کاملLikelihood and Fairness in Multidimensional Item Response Theory
In multidimensional item response theory, it is possible for the estimate of a subject’s ability in some dimension to decrease after they have answered a question correctly. When this occurs, the fairness of the estimate may be called into question. This paper investigates how and when this form of non-monotonicity occurs. We demonstrate that many response models and statistical estimates can p...
متن کاملCognitive Assessment Applying with Item Response Theory
Using item response theory (IRT) in computer adaptive test (CAT) is critical to assess learners’ readiness for further learning. This theory has assumptions concerning the mathematical relationship between learner’s abilities and item responses. A numerical value from the theory has potential to decide who the best learner is. The IRT score only provides the learner’s result and lack of the ass...
متن کاملOn multidimensional item response theory -- a coordinate free approach
A coordinate system free definition of complex structure multidimensional item response theory (MIRT) for dichotomously scored items is presented. The point of view taken emphasizes the possibilities and subtleties of understanding MIRT as a multidimensional extension of the “classical” unidimensional item response theory models. The main theorem of the paper is that every monotonic MIRT model ...
متن کاملLinear Item Response Theory, Nonlinear Item Response Theory, and Factor Analysis: A Unified Framework
What it is now known as item response modeling [for an overview see van der Linden and Hambleton (1997)] originated as an effort to overcome the limitations of the factor model when applied to test items. Test items are most often categorical in nature, whereas the factor model was designed for continuous data. Unfortunately, over the years item response modeling and factor modeling have develo...
