|Abstract Title:||Student Understanding of Quantum Measurement and Uncertainty|
|Abstract:||Introductory courses in classical physics appear to be promoting in students a perspective we are calling local realism, where, for example, it is assumed that a particle's position and momentum have simultaneous reality – both physical quantities can be described with well-defined values at all times. Such a perspective can be problematic for introductory quantum physics students, who must develop new epistemic and ontological resources in order to properly interpret what it means to have knowledge of quantum observables. We document this evolution in student thinking in part through pre/post-instruction evaluations using the CLASS survey. We further characterize variations in student epistemic and ontological commitments by examining responses to coupled essay questions and quantum attitudes statements. We find that, despite performance level in the course, many students are still exhibiting a realist perspective in some quantum contexts. We also find that this effect can be significantly influenced by instruction, where we observe variations for courses with differing learning goals.
