Introduction to Many-Facet Rasch Measurement

Analyzing and Evaluating Rater-Mediated Assessments. 2nd Revised and Updated Edition

«[…] this book covers a diverse array of both basic and important topics related to Rasch measurement, providing insights into complexities and intricacies involved in rater-mediated performance assessment. This books is highly recommended to researchers, practitioners, and other stakeholders who are interested in Rasch measurement, but only have a limited understanding of Rasch modeling. The book is also suitable for advanced learners and applied researchers who could consult advanced modeling techniques discussed in Chapters 8 and 9.»<br /> (Chao Han, Measurement: Interdisciplinary Research and Perspectives, 2019, Vol. 17, N° 2)<br /><br /> «The strengths of this book are numerous. Discussing the MFRM approach in the context of language testing can make the concept of facets (raters, students, etc.) and their associated issues (e.g., rater variability) appealing to educators. The book discusses the limitations of standard approaches in reducing between-rater variation and shows how the MF»
