Many instructors have experienced a situation where students demonstrate content competency on one task but fail to do so on an analogous task that requires the application of the same content understanding and reasoning skills. Observed inconsistencies in student performance could be interpreted in several ways. For example, in some cases, it could be argued that students may simply not possess the formal knowledge and skills necessary to arrive at a correct answer. In other cases, however, students may switch their cognitive mode, seeming to abandon the formal knowledge and skills in favor of (perhaps more appealing, but incorrect) intuitive ideas. In order to address the identified patterns of incorrect and inconsistent responses, it is critical to have a diagnostic instrument that allows for (1) disentangling reasoning from conceptual understanding and (2) pinpointing specific aspects of student thinking (conceptual understanding, reasoning strategies, or both) that should be targeted during instruction. Already existing assessment instrument in physics tend to measure improvements in overall student performance rather than documenting growth along both dimensions (i.e., conceptual understanding and reasoning). In this presentation, I will discuss current efforts directed toward the development of the Dimensions of Conceptual Understanding and Reasoning Instrument and will outline future work that focuses on multiple data streams used for establishing validity and reliability.

I discuss how lattice stochastic methods provide a synergistic interplay between the fields of particle physics and condensed matter/solid-state physics.  I describe how such synergy has enabled simulations of the largest lattices to date used to determine the quantum phase transition of the Hubbard model on the 2D honeycomb lattice.  I also provide an example of how recent algorithmic advances in tackling the sign problem in simulations of solid-state systems can potentially benefit particle physics.
