SUMMARY:Applications of Item Response Theory (IRT) - Professor John Rust (
 University of Cambridge)
DTSTART:20110216T140000Z

UID:TALK22746@talks.cam.ac.uk
CONTACT:Michal Kosinski
DESCRIPTION:The modern era in psychometrics began with the publication of 
 Lord and Novick’s ‘The theory of mental test scores’ which introduce
 d item response theory (IRT) to the world. IRT\, together with its simplif
 ied version\, the Rasch model\, form the core of developments in assessmen
 t research today. They enable efficient use of item banking procedures\, c
 omputer adaptive testing\, and more transparent and effective test constru
 ction and item choice procedures. More recently\, the common ground and th
 eoretical underpinning between Structural Equation Modeling and IRT have b
 een successfully bridged\, giving birth to new and powerful psychometric p
 rogrammes such as Mplus\, R and Stata\, that enable pipeline accuracy in t
 est production procedures. We can’t teach these here\, but at the end of
  this session you should be familiar with the item characteristic curve an
 d be able to recognize a good pattern of curves from a poor one in terms o
 f the three parameters.
