Many groups are underrepresented and unequally served in physics classes. We study differences in learning by gender, race, ethnicity, first generation, and rurual/urban status. These various dimensions interact in unexpected ways.

Gender Differences and the CSEM

We discovered that conceptual performance differences on the Conceptual Survey of Electricity and Magnetism between men and women were also present, but to a weaker degree, in other assignments in an introductory physics; however, no quantitative performance differences were detected.

Item Bias and the FCI

We used differential item function theory to show 9 items in the Force Concept Inventory demonstrated substantial bias with most biased against women. We proposed a reduced instrument to repair these flaws.

Item Bias and the FMCE and CSEM

We used differential item function theory to show that the Force and Motion Conceptual Evaluation and the Conceptual Survey of Electricity and Magnetism were substantially less biased than the FCI.

Other Populations

We have begun to explore differences in conceptual performance for other populations examining race, ethnicity, first generation status, and rural/urban status.
