Examination of map reading skills with orienteering activity: An example of 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 ...

A Many-facet Rasch Model to Detect Halo Effect in Three Types of Raters

Raters play a central role in rater-mediated assessment, and rater variability manifested in various forms including rater errors contributes to construct-irrelevant variance which can adversely affect an examinee’s test score. Halo effect as a subcomponent of rater errors is one of the most pervasive errors which, if not detected, can result in obscuring an examinee’s score and threatening val...
