Greetings Rasch SIG colleagues,
I hope 2014 finds you well. In lieu of AERA fast approaching, I wanted to share a few brief comments. First, I wanted to acknowledge the efforts our Program Co-Chairs Kelly Bradley and Jessica Cunningham for their work in putting together this year's Rasch Measurement SIG sessions. This year's program includes several paper and poster sessions focusing on everything from instrument development to item and person fit and Rasch-based modeling approaches. I hope you'll make every effort to seek out these events if you'll be able to attend AERA.
I'm also quite excited to report that David Andrich has graciously agreed to speak at this year's business meeting. The title of his talk is "On Rasch Measurement Theory" in which he presents a timely discourse on the work of Georg Rasch:
"This presentation argues that the contribution and significance of the work of Georg Rasch to the understanding and practice of social measurement is both understated and misunderstood when it is seen primarily as an exercise in response modeling. It is argued that a complex of understandings of his contribution, which entails (i) an a-priori criterion of invariance of comparisons within a specified frame of reference, (ii) rendering this criterion in the form of class of probabilistic models which have sufficient statistics for all parameters, (iii) articulating these models with a body of knowledge of statistical inference, and (iv) anchoring the models in an empirical paradigm of item and test construction, justifies it being referred to as the Rasch Measurement Theory. In making the case, the paper makes some comparisons and contrasts with the principles of Classical Test Theory and Item Response Theory and suggests that both these approaches to social measurement have less of a claim to being called a theory than the approach by Rasch."
Hopefully his abstract whets your appetite a bit and will have you marking your calendar accordingly. As with recent history, you can expect the business meeting to be in line with the past few in that I will be providing a brief State of the SIG address prior to introducing David. The meeting is scheduled for Thursday, April 3rd from 6:15pm to 7:45pm. Hors d'oeuvres and a cash bar will be provided. I will send out more detailed information on all presentations and logistics prior to the AERA conference.
I also wanted to acknowledge the fact that we have just wrapped up an election which will mark the first implementation of SIG bylaws. Specifically we'll be welcoming three newly elected SIG officers. Of course results are yet to be tallied and delivered, so I'm afraid I have nothing official to report as of this publication. But stay tuned, as we shall know within the month.
Thanks kindly. I look forward to seeing you in Philadelphia!
