Çok Boyutlu Madde Tepki Kuramı Modelleri ve Paket Programları İçin Karşılaştırmalı Analizler

Abstract

Recently many researchers advocate that item and person interactions are very complicate and these interactions can not be assumed as unidimensional. These researchers prefer to use of the multidimensional item response (MIRT) models in their studies. Like IRT models MIRT models can be used also with different test applications (such as (1) Equating; (2) Linking; (3) Differential Item Function (DIF); (4) Standard setting; and others). All those applications have the same assumption that item parameters are calibrated as accurately as possible. Computer programs, parameter estimation techniques and test conditions have most important effects on the estimation of item parameter. Every estimation technique and software have different properties than each other. Some type of item parameter recovery studies typically provide a comparison of different models, different sample sizes, or different software.
