Reliability of Ratings of Multidimensional Fluency Scale with Many-Facet Rasch Model

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...

Rater Errors among Peer-Assessors: Applying the Many-Facet Rasch Measurement Model

In this study, the researcher used the many-facet Rasch measurement model (MFRM) to detect two pervasive rater errors among peer-assessors rating EFL essays. The researcher also compared the ratings of peer-assessors to those of teacher assessors to gain a clearer understanding of the ratings of peer-assessors. To that end, the researcher used a fully crossed design in which all peer-assessors ...

Intellectual Achievement Responsibility. a Many-facet Rasch Model Analysis of the Scale by Crandall, Katkovsky and Crandall

The present study consists in the analysis of the responses of 485 high school Italian students to the items of the Intellectual Achievement Responsibility questionnaire (IAR; Crandall, Katkovsky, & Crandall, 1965) in view of the definition of a new form of the scale. The Italian version by Nigro and Galli (1988) was applied to the participants. The data were analyzed by means of the Many-Facet...
