Differential Performance Of Poor Readers In International Mathematics Tests By Item Formats, Luc Le
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 …
Investigating Gender Differential Item Functioning Across Countries And Test Languages For Pisa Science Items, Luc Le
Dr Luc Tu Le
This study uses PISA cycle 3 field trial data to investigate the relationships between gender differential item functioning (DIF) across countries and test languages for science items and their formats and the four other dimensions defined in PISA framework: focus, context, competency, and scientific knowledge. The data used were collected from 60 test language groups by 50 participating countries with a total of about 83,000 15-year-old students. An IRT method is used to detect the gender uniform DIF for each of the language groups and the whole international sample. Gender directions have been drawn for each of the five item …
