Abstract Title: Improving student understanding of degenerate perturbation theory in quantum mechanics
Abstract: We investigate student difficulties with degenerate perturbation theory in quantum mechanics by administering free-response and multiple-choice questions and conducting individual interviews with advanced students. We find that students display many common difficulties related to this topic. To improve student understanding, we use these difficulties as resources and develop a Quantum Interactive Learning Tutorial (QuILT) along with a pre-test and a post-test using an iterative approach. We will discuss the development and evaluation of the QuILT. We thank the National Science Foundation for support.
