Many-Facet Rasch Measurement
This chapter provides an introductory overview of many-facet Rasch measurement (MFRM). Broadly speaking, MFRM refers to a class of measurement models that extend the basic Rasch model by incorporating more variables (or facets) than the two that are typically included in a test (i.e., examinees and items), such as raters, scoring criteria, and tasks. Throughout the chapter, a sample of rating d...
متن کاملRasch Trees: A New Method for Detecting Differential Item Functioning in the Rasch Model.
A variety of statistical methods have been suggested for detecting differential item functioning (DIF) in the Rasch model. Most of these methods are designed for the comparison of pre-specified focal and reference groups, such as males and females. Latent class approaches, on the other hand, allow the detection of previously unknown groups exhibiting DIF. However, this approach provides no stra...
متن کاملA penalty approach to differential item functioning in Rasch models.
A new diagnostic tool for the identification of differential item functioning (DIF) is proposed. Classical approaches to DIF allow to consider only few subpopulations like ethnic groups when investigating if the solution of items depends on the membership to a subpopulation. We propose an explicit model for differential item functioning that includes a set of variables, containing metric as wel...
متن کاملExamining the Teachers’ Sense of Efficacy Scale at the Item Level With Rasch Measurement Model
The purpose of this study is to examine the psychometric quality of the Teachers’ Sense of Efficacy Scale (TSES) with data collected from 554 teachers in a U.S. Midwestern state. The many-facet Rasch model was used to examine several potential contextual influences (years of teaching experience, school context, and levels of emotional exhaustion) on item functioning within the TSES. Results sug...
متن کاملItem Bias Detection using the Log linear Rasch Model
A method is proposed for the detection of item bias with respect to observed or unobserved subgroups. The method uses quasi-loglinear models for the incomplete subgroup x testscore x item 1 x x itek k contingency table. If subgroup membership is unknown the models are Haberman's incomplete-latent-class models. The (conditional) Rasch model is formulated as a quasi-loglinear model. The parameter...
