recent years, item response theory has been widely used in large-scale
psychological and educational testing. As its name indicates, item response
theory primarily focuses on the analysis at the item level in contrast with
classical test theory which mainly focuses on the analysis at the test level.
The most important property of item response theory is that the person
statistics (eg ability or attitude scores) are independent of the item samples
and the item statistics (eg item difficulty and item discrimination) are
independent of the examinee samples. This invariance property of item response
theory makes it theoretically more appropriate to be used in some measurement
situations, such as test equating and computerised adaptive testing. In this
workshop, based on the basic item response models such as the Rasch model, we
will discuss how item response theory works and how it can be used for test
equating purpose. In addition, we will also analyse the advantages and
disadvantages of item response theory relative to classical test theory.
Dr Serena Luo
is a research scientist with the Centre for Research in Pedagogy and Practices,
areas are in educational psychology, particularly non-cognitive variables in
self-regulated learning such as self-concept, achievement goals, achievement
emotions, learning strategies and social cultural understanding of learning.
Her doctoral thesis was on self-complexity, of which she received the Award for
Outstanding Research Postgraduate Student (2008). She is “intrinsically”
interested in quantitative research methodology and has published a number of
papers both on educational psychology and on psychological measurement. Serena
is passionate about using her quantitative skills to disentangle and reveal
meaningful relationships among educational variables and looks forward to
collaboration with researchers in NIE and internationally.
