Improving student understanding of addition of angular momentum in quantum mechanics
Guangtian Zhu, Chandralekha Singh
We describe the difficulties advanced undergraduate and graduate students have with concepts related to addition of angular momentum in quantum mechanics. We also describe the deve…
Improving Students' Understanding of Quantum Measurement Part 1: Investigation of Difficulties
Guangtian Zhu, Chandralekha Singh
We describe the difficulties that advanced undergraduate and graduate students have with quantum measurement within the standard interpretation of quantum mechanics. We explore the…
Improving Students' Understanding of Quantum Measurement Part 2: Development of Research-based Learning Tools
Guangtian Zhu, Chandralekha Singh
We describe the development and implementation of research-based learning tools such as the Quantum Interactive Learning Tutorials (QuILTs) and peer instruction tools to reduce stu…
Students' Understanding of Stern Gerlach Experiment
Guangtian Zhu, Chandralekha Singh
The Stern Gerlach experiment has played a central role in the discovery of spin angular momentum and it has also played a pivotal role in elucidating foundational issues in quantum…
Improving Students' Understanding of Quantum Mechanics via the Stern-Gerlach Experiment
Guangtian Zhu, Chandralekha Singh
The Stern-Gerlach experiment has played a central role in the discovery of spin angular momentum. It can also play a pivotal role in teaching the formalism of quantum mechanics usi…
Surveying Students' Understanding of Quantum Mechanics
Chandralekha Singh, Guangtian Zhu
Development of conceptual multiple-choice tests related to a particular physics topic is important for designing research-based learning tools to reduce the difficulties. We explor…
