Item Selection and Ability Estimation Procedures for a Mixed-Format Adaptive Test

Applied Measurement in Education, 2012
In this study we compared five item selection procedures using three ability estimation methods in the context of a mixed-format adaptive test based on the generalized partial credit model. The item selection procedures used were maximum posterior weighted information, maximum expected information, maximum posterior weighted Kullback-Leibler ...

Bi-Factor MIRT Observed-Score Equating for Mixed-Format Tests

Applied Measurement in Education, 2016
ABSTRACTThe main purposes of this study were to develop bi-factor multidimensional item response theory (BF-MIRT) observed-score equating procedures for mixed-format tests and to investigate relative appropriateness of the proposed procedures. Using data from a large-scale testing program, three types of pseudo data sets were formulated: matched ...

A Multidimensional Partial Credit Model With Associated Item and Test Statistics: An Application to Mixed-Format Tests

Applied Psychological Measurement, 2006
Multidimensional item response theory (IRT) models have been proposed for better understanding the dimensional structure of data or to define diagnostic profiles of student learning. A compensatory multidimensional two-parameter partial credit model (M-2PPC) for constructed-response items is presented that is a generalization of those proposed to date ...

The impact of scoring later on mixed format adaptive testing

This study investigated the impact of scoring polytomous items later on measurement precision, classification accuracy, and test security in mixed-format adaptive testing. Utilizing the shadow test approach, a simulation study was conducted across various test designs, lengths, number and location of polytomous item.

Refining the asymptotically correct standardization of person‐fit statistics for mixed‐format tests

British Journal of Mathematical and Statistical Psychology
Abstract Sinharay ( Psychometrika , 2016, 81, 992) suggested the asymptotically correct standardized version of a class of person‐fit statistics for mixed‐format tests. This paper provides an alternative and arguably simpler derivation of the standardization.
