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.
Dates 17th -19th May 2006; 13th-15th September 2006; 13th-15th December
2006
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 software
" Write a good Rasch paper.
Dates: 22nd-24th May 2006; 18th-20th September 2006.
Advanced Issues Workshop.
This workshop will concentrate on introducing 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. The approach
taken with be that of working in groups to solve measurement issues.
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
" Use the item bank to inform and use Computer Adaptive Testing
software. Currently we use FastTEST pro.
" Understand the potential for unfolding models and use the Ratefold
Software.
Dates: 25th-26th May 2006; 21st-22nd September 2006.
Advanced Workshop (2) on Dimensionality.
This workshop will build on the previous advanced workshop and will use the
simulation of data to address problems associated with multidimensionality
in data. Participants will work on a common problem with the intention of
comparing and contrasting traditional test theory approaches with modern
test theory approaches based on the Rasch model.
At the end of this workshop, students should be able to:
" Simulate data to address dimensionality issues
" Undertake and interpret traditional approaches to dimensionality.
" Produce comparative analysis from both RUMM2020 and WINSTEPS
" Write a collective group paper on the substantive topic given for
the workshop.
Dates 25th-27th September 2006.
