Keebaugh, Christof; Marshman, Emily; Singh, Chandralekha – Physical Review Physics Education Research, 2019
We discuss an investigation of student difficulties with the corrections to the energy spectrum of the hydrogen atom for the intermediate field Zeeman effect using degenerate perturbation theory (DPT). The investigation was carried out in advanced quantum mechanics courses by administering free-response and multiple-choice questions and conducting…

Maries, Alexandru; Sayer, Ryan; Singh, Chandralekha – Physical Review Physics Education Research, 2017
Research suggests that introductory physics students often have difficulty using a concept in contexts different from the ones in which they learned it without explicit guidance to help them make the connection between the different contexts. We have been investigating advanced students' learning of quantum mechanics concepts and have developed…

Young, Daniel E.; Meredith, Dawn C. – Physical Review Physics Education Research, 2017
The resources framework provides a useful and generative model of student thinking and learning. In particular, it suggests various strategies for instruction such as priming resources and refining intuition that allow students to build on knowledge they already have. In this paper, we describe the affordances of the resources framework in guiding…
