Differential Performance Of Poor Readers In International Mathematics Tests By Item Formats, Luc Le Aug 2011

Differential Performance Of Poor Readers In International Mathematics Tests By Item Formats, Luc Le

Dr Luc Tu Le

The important role of language, including reading, on student performance on assessments in school academic areas such as mathematics has been addressed in number of studies. Although positive relations between different aspects of reading and mathematics performance have been investigated, there have been few studies focusing on the interaction between the context of the mathematics item and student reading proficiency, and most of those there were related only to the verbal loading. Recently, a low correlation between verbal loading and item difficulty was found for PISA mathematics items. This study used PISA 2003 mathematics data with 41 countries with about …

In operational testing programs using item response theory (IRT), item parameter invariance is one of essential requirements in common item equating designs. However, in practice, the stability of item parameters can be affected by many factors. Particularly, this study utilised data from the large-scale Graduate Skills Assessment (GSA) in 2010 to investigate the change of Rasch item difficulty by item positions. The test included 78 multiple-choice items and was presented in eight test forms by arranging the items in different orders. Items addressed three components of generic skills: Critical Thinking, Problem Solving and Interpersonal Understandings. Each test form was randomly …
