Student difficulties with Boundary Conditions in electrodynamics
Qing X. Ryan, Steven J. Pollock, Bethany R. Wilcox
Boundary conditions (BCs) are considered as an important topic that advanced physics under- graduates are expected to understand and apply. We report findings from an investigation…
Upper-division student difficulties with Separation of Variables
Bethany R. Wilcox, Steven J. Pollock
Separation of variables can be a powerful technique for solving many of the partial differential equations that arise in physics contexts. Upper-division physics students encounter…
Validation and analysis of the coupled multiple response Colorado upper-division electrostatics (CUE) diagnostic
Bethany R. Wilcox, Steven J. Pollock
Standardized conceptual assessment represents a widely-used tool for educational researchers interested in student learning within the standard undergraduate physics curriculum. Fo…
Upper-division student difficulties with the Dirac delta function
Bethany R. Wilcox, Steven J. Pollock
The Dirac delta function is a standard mathematical tool that appears repeatedly in the undergraduate physics curriculum in multiple topical areas including electrostatics, and qua…
