Effects Of Item Positions On Their Difficulty And Discrimination : A Study In Pisa Science Data Across Test Language And Countries, Luc T. Le
OECD Programme for International Student Assessment (PISA)
This study was based on a four-cluster rotation design of 13 linked test booklets from PISA 2006 science data. It investigated effects of item positions on their difficulty and discrimination parameter estimates obtained from one and two parameter IRT Partial Credit models. The analyses were done separately for 57 test language groups from 53 countries with a total of about 340,000 students.
The results revealed that for all of the test language groups the items tended to become more difficult when they were located later in the test. However, a high linear relationship between the item difficulty estimates by the …

The Influence Of Equating Methodology On Reported Trends In Pisa, Eveline Gebhardt, Ray Adams
The Influence Of Equating Methodology On Reported Trends In Pisa, Eveline Gebhardt, Ray Adams
Prof Ray Adams
In 2005 PISA published trend indicators that compared the results of PISA 2000 and PISA 2003. This paper explores the extent to which the outcomes of these trend analyses are sensitive to the choice of test equating methodologies, the choice of regression models and the choice of linking items. To establish trends, PISA equated its 2000 and 2003 tests using a methodology based on Rasch Modelling that involved estimating linear transformations that mapped 2003 Rasch-scaled scores to the previously established PISA 2000 Rasch-scaled scores. This paper compares the outcomes of this approach with an alternative, which involves the joint Rasch …
