| Abstract: | Physics instructors and education researchers use research-based assessments (RBAs) to evaluate students' preparation for physics courses, including mathematics and physics content. Using separate mathematics and physics RBAs consumes course time. We are developing the Mechanics Cognitive Diagnostic as an online test using computerized adaptive testing and cognitive diagnostic models. The MCD assesses mathematics and physics content knowledge within a single assessment. We used an evidence-centered design framework to inform the extent to which our models of skills students develop in physics courses fit the data from three mathematics RBAs. We used responses from the Calculus Concept Assessment, Calculus Concept Inventory, and Pre-calculus Concept Assessment. The "deterministic inputs, noisy 'and' gate'' (DINA) analyses demonstrated a good fit for skills. The classification accuracies for the skills were satisfactory. Including items of the three mathematics RBAs in the MCD's item-bank enables flexible assessment of mathematics and physics skills as per instructor's needs. |
