The impact of peer interaction on the responses to clicker questions in an upper-level quantum mechanics course
Ryan Sayer, Emily Marshman, Chandralekha Singh
In this case study, we investigated the effectiveness of peer interaction on responses to in-class clicker questions in an upper-level quantum mechanics course. We analyzed student…
Closing the Gap between Teaching and Assessment
Chandralekha Singh
Evidence-based teaching is based upon a model of learning in which assessment plays a central role.
Improving Student Understanding of Magnetism
Chandralekha Singh
Formally investigating the sources of students' difficulties around specific subjects is crucial for developing appropriate strategies to help students. We have been studying diffi…
Graduate teaching assistants use different criteria when grading introductory physics vs. quantum mechanics problems
Charles Henderson, Emily Marshman, Ryan Sayer +2
Physics graduate teaching assistants (TAs) are often responsible for grading. Physics education research suggests that grading practices that place the burden of proof for explicat…
Physics graduate teaching assistants' beliefs about a grading rubric: Lessons learned
Edit Yerushalmi, Ryan Sayer, Emily Marshman +2
Explication and reflection on expert vs. novice considerations within the problem-solving process characterize a cognitive apprenticeship approach for the development of expert-lik…
Student difficulties with representations of quantum operators corresponding to observables
Emily Marshman, Chandralekha Singh
Dirac notation is used commonly in quantum mechanics. However, many upper-level undergraduate and graduate students in physics have difficulties with representations of quantum ope…
