Peer reviewed Peer reviewed
PDF on ERIC Download full text
Aybek, Eren Can; Demirtasli, R. Nukhet – International Journal of Research in Education and Science, 2017
This article aims to provide a theoretical framework for computerized adaptive tests (CAT) and item response theory models for polytomous items. Besides that, it aims to introduce the simulation and live CAT software to the related researchers. Computerized adaptive test algorithm, assumptions of item response theory models, nominal response…

Choi, Seung W.; Podrabsky, Tracy; McKinney, Natalie – Applied Psychological Measurement, 2012
Computerized adaptive testing (CAT) enables efficient and flexible measurement of latent constructs. The majority of educational and cognitive measurement constructs are based on dichotomous item response theory (IRT) models. An integral part of developing various components of a CAT system is conducting simulations using both known and empirical…

The Random-Threshold Generalized Unfolding Model and Its Application of Computerized Adaptive Testing
Peer reviewed Peer reviewed
Direct linkDirect link
Wang, Wen-Chung; Liu, Chen-Wei; Wu, Shiu-Lien – Applied Psychological Measurement, 2013
The random-threshold generalized unfolding model (RTGUM) was developed by treating the thresholds in the generalized unfolding model as random effects rather than fixed effects to account for the subjective nature of the selection of categories in Likert items. The parameters of the new model can be estimated with the JAGS (Just Another Gibbs…

A Genre-Based Perspective for the Development of Communicative Computerized Adaptive Tests
Peer reviewed Peer reviewed
Direct linkDirect link
Lopez-Cuadrado, Javier; Armendariz, Ana J.; Latapy, Marion; Lopisteguy, Philippe – Educational Technology & Society, 2008
This paper discusses the communicative potentials of Computerized Adaptive Testing. The study is based on a model that offers a set of independent communicative concepts to describe the Genre of an interactive application. This model will be the starting point to analyze the stages of the interaction cycle that are typically inherent to every…

Item Response Modeling with BILOG-MG and MULTILOG for Windows
Peer reviewed Peer reviewed
Direct linkDirect link
Rupp, Andre A. – International Journal of Testing, 2003
Item response theory (IRT) has become one of the most popular scoring frameworks for measurement data. IRT models are used frequently in computerized adaptive testing, cognitively diagnostic assessment, and test equating. This article reviews two of the most popular software packages for IRT model estimation, BILOG-MG (Zimowski, Muraki, Mislevy, &…

Item Response Theory: Introduction and Bibliography. Research Report No. 196.
PDF on ERIC Download full text
Hambleton, Ronald K. – 1989
A brief overview of item response theory is provided, and a 186-item bibliography of books and articles on the subject dating from 1953 to June 1989 is presented. The overview includes a definition of the theory, a discussion of its development and application, and comparisons with classical test theory. All publications in the bibliography were…
