Student Difficulties with Operators Corresponding to Observables in Dirac Notation

Analogous Patterns of Student Reasoning Difficulties in Introductory Physics and Upper-Level Quantum Mechanics

Here we focus on an investigation that suggests that, even though Dirac notation is used extensively, many advanced undergraduate and Ph.D. students in physics have difficulty expressing the identity operator and other Hermitian operators corresponding to physical observables in Dirac notation. We first describe the difficulties students have with expressing the identity operator and other Hermitian operators corresponding to observables in Dirac notation. We then discuss how the difficulties found via written surveys and individual interviews were used as a guide in the development and validation of a Quantum Interactive Learning Tutorial (QuILT) to help students develop a good grasp of these concepts. We also discuss the effectiveness of the QuILT based on in-class evaluations. We thank the National Science Foundation for support.

Ask your colleagues how they learned to do research. Most of us learned how to do research by reading publications our advisor told us to read and discussing the research with the research group or the group leader. We basically learned by doing something similar to that which has been already done and failing. In the failing, we modified some part of what we were doing and tried again. In this presentation I will present what my students do in Junior Lab to learn about designing a lab, communicating the results, and decision making in the process. I will also share my evaluation of their actions and reflect upon this process.

Junior Physics Laboratory: Scientific Reasoning, Communication & Decision Making

Students’ self-efficacy, interest and identity in physics can influence their learning, performance and career decisions. Therefore, we investigated the impact of learning environment on male and female students’ physics self-efficacy, interest and identity in calculus-based introductory physics. Findings can be useful in creating equitable and inclusive learning environments in which all students can thrive. We thank the National Science Foundation for support.

How learning environment predicts male and female students’ physics motivational beliefs in introductory physics courses

Student outcomes in introductory physics courses influence their retention in STEM disciplines and future career aspirations. This study investigates how the learning environment predicts male and female students’ outcomes, including grade, self-efficacy, interest, and identity. These findings can be useful to provide support and to create an equitable and inclusive learning environment to help all students excel in algebra-based physics courses.
