An Instructional Module on Mokken Scale Analysis
Wind, Stefanie A.
Educational Measurement: Issues and Practice, v36 n2 p50-66 Sum 2017
Mokken scale analysis (MSA) is a probabilistic-nonparametric approach to item response theory (IRT) that can be used to evaluate fundamental measurement properties with less strict assumptions than parametric IRT models. This instructional module provides an introduction to MSA as a probabilistic-nonparametric framework in which to explore measurement quality, with an emphasis on its application in the context of educational assessment. The module describes both dichotomous and polytomous formulations of the MSA model. Examples of the application of MSA to educational assessment are provided using data from a multiple-choice physical science assessment and a rater-mediated writing assessment.
