UV9220 – Introduction to Rasch-analysis with Rumm 2030

Course content

  • Basic principles of the Rasch model for dichotomous data: introducing the basic mathematical model, perspectives on the Rasch model as fundamental measurement, interpreting item and person location, item characteristic curves, wright maps, test targeting
  • Extension of the model to polytomous data (the rating scale and partial credit model): interpretation of thresholds and category characteristic curves (including the problem of reversed thresholds)
  • The principle of invariance of measurement: assessing model fit in RUMM (compared to other widely used fit indexes), assessing differential item functioning in RUMM, assessing dimensionality of data in RUMM. The application of RUMM 2030 for conducting Rasch analysis of data.
  • Introduction to advanced topics: e.g. using subtests, using the Rasch model for anchoring, building facets into the model etc.

Learning outcome

The aim of the course is to provide insight into the theoretical underpinning of Rasch analysis and to discuss the use of Rasch analysis to educational data (cognitive content as well as questionnaire data). Students should be able to carry out analysis and interpret their findings after participation on the course.
Part of the time will be dedicated to carrying out and interpreting analysis of a data set. Participants will have the opportunity to bring their own data and work on these Wednesday. The lecturers will assist in analyzing and interpreting your data.
