A. Introduction to Rasch Analysis
A workshop to introduce Rasch analysis. It will suit those working in the
measurement of outcomes in the health sciences, of attitudinal data in the
social sciences, or in educational testing. It will take the form of
hands-on tuition in using the Rasch Unidimensional Measurement Models
(RUMM2020) software package. At the end of the two-and-a-half days workshop
students should understand and be able to analyse data, using RUMM2020,
for:
"       Internal construct validity (Unidimensionality);
"       Category probability patterns for polytomous items;
"       Differential Item Functioning;
"       Scaling Characteristics.

B. Intermediate Rasch analysis.
This workshop will look at more advance topics using the RUMM2020 software,
and will include issues of pooling data from international studies, linking
scales and writing a Rasch paper. Students should have completed the
introductory course, or have experience with RUMM software.
At the end of this workshop, students should be able to:
"       Adjust estimates of patient ability (or trait) for cross-cultural
differences in outcome measures (to facilitate pooled data in international
studies).
"       Conduct multi-faceted Rasch analysis 
"       A brief comparison with WINSTEPS
"       Write a good Rasch paper. 

C. Advanced Workshop.
This workshop will concentrate of substantive methodological issues using a
range of software, and will include simulation of data,  issues in
developing item banks, Computer Adaptive Testing and the exploration of
alternative approaches, e.g. unfolding models.
 At the end of this workshop, students should be able to:
"       Simulate data to meet the requirements of different types of Item
response Theory Models.
"       Establish an item bank 
"       Develop Computer Adaptive Testing algorithms.
"       Understand the potential for unfolding models.
