GSE Psychometric Laboratory

Rasch course

Rasch theory

A Course in Rasch Measurement Theory will be held in January 2020 in Sydney, NSW in collaboration with Professor Jim Tognolini

Course outline

Rasch models for measurement are used in large scale national and international assessments, not only to analyse test data after collection, but to use as criteria for design of test items and their administration. The GSE Psychometric Laboratory undertakes research and development for application to the broad area of measurement and assessment in education and the social sciences including psychology, health and marketing. The GSE Psychometric Laboratory does research in all areas of Rasch models for measurement, in particular epistemological, applied, and in software development. This is an opportunity to study with researchers who have made advancement in all these fields.

Course Structure:

The course will be at an intermediate level and consist of two parts:
1. Part I – Overview of introductory principles of Rasch measurement and the RUMM2030 software. RUM2030 is a very easy to use interactive program that analyses data according to the Rasch measurement model and provides comprehensive diagnostics in both tabular and graphical forms. It can also be used for large scale assessments including vertical equating.
2. Part II - Rasch Measurement Theory.
Participants have the option of attending only Part I or II or both parts of the course. 

The content of the course is based on two online units that have been taught by Prof Andrich and Dr Marais for many years. These units are EDUC5638 (Introduction to Classical and Rasch Measurement Theories) and EDUC5606 (Advanced Course in Rasch Measurement of Modern Test Theory)

Topics covered:

  • Theory of social measurement and Rasch models
  • Revision of Rasch's model for dichotomous responses and his original work
  • Multiple choice items and guessing
  • Understanding the Polytomous Rasch Model
  • Model fit statistics
  • Advanced understanding of differential item functioning (DIF): real and artificial DIF
  • Vertical equating and DIF
  • Assessing two violations of the assumption of local independence: multidimensionality and response dependence
  • Facets analysis and analysis of longitudinal data

Students enrolled obtain:

  1. Printed copy of the text book or similar
  2. Selected readings in electronic format
  3. A copy of the new RUMM2030 software for the duration of the course valid for 6 months

Students are encouraged to bring their own data to analyse.
