With computers becoming more ubiquitous in our daily lives and in our classrooms, questions of how students interact and learn with physical experiments and computer simulations are central in science education. We investigated how students' ideas about pulleys were influenced by the use of physical and virtual manipulatives. We found that there were(More)
Recent research results have failed to support the conventionally held belief that students learn physics best from hands-on experiences with physical equipment. Rather, studies have found that students who perform similar experiments with computer simulations perform as well or better on measures of conceptual understanding than their peers who used(More)
Operators play a central role in the formalism of quantum mechanics. In particular, operators corresponding to observables encode important information about the results of quantum measurements. We interviewed upper-level undergraduate physics majors about their understanding of the role of operators in quantum measurements. Previous studies have shown that(More)
How can one convey to interested teachers and researchers nuances of the ways an instructor teaches? of the ways students learn within that instructional context? of the details of that student learning? What aspects of these issues, motivated by the need to communicate a culture of teaching and learning, contribute to a culture of research? One(More)
Quantum probability theory offers a viable alternative to classical probability, although there are some ambiguities inherent in transferring the quantum formalism to a less determined realm. A number of physicists are now looking at the applicability of quantum ideas to the assessment of physics learning, an area particularly suited to quantum probability(More)
