Gender-related differential item functioning (DIF) was examined in a context in which 3,946 middle school students received mathematics instruction focusing on problem solving. Reasons why four tasks on the performance assessment favored female students and two favored male students are discussed. (SLD)

Three different differential item functioning (DIF) detection methods were used to examine the extent to which items in a mathematics performance assessment functioned differently for matched gender groups from a sample of 1,782 sixth and seventh graders. Implications of the finding that two items were potentially biased are discussed. (SLD)

This study examined gender-related differential item functioning (DIF) using a mathematics performance assessment, the QUASAR Cognitive Assessment Instrument (QCAI), administered to middle school students. The QCAI was developed for the Quantitative Understanding: Amplifying Student Achievement and Reading (QUASAR) project, which focuses on…

This study used three different differential item functioning (DIF) procedures to examine the extent to which items in a mathematics performance assessment functioned differently for matched gender groups. In addition to examining the appropriateness of individual items in terms of DIF with respect to gender, an attempt was made to identify…
