Passon, Oliver; Zügge, Thomas; Grebe-Ellis, Johannes – Physics Education, 2019

Elementary particle physics is gradually implemented into science curricula at the high school level. However, common presentations on educational, semi-technical or popular level contain or support severe misconceptions. We discuss in particular the notion of 'particle', the interaction between them and the use of Feynman diagrams. In many cases…

Truhlar, Donald G. – Journal of Chemical Education, 2019

Dispersion forces are ubiquitous in chemistry, yet they are often misunderstood. This article provides background into why they are called dispersion forces and explains how to describe them in terms of time-independent quantum mechanics. The article also describes the breakdown of the multipole series that is often used to describe dispersion…

Zhu, Guangtian; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2012

We describe the development and implementation of research-based learning tools such as the Quantum Interactive Learning Tutorials and peer-instruction tools to reduce students' common difficulties with issues related to measurement in quantum mechanics. A preliminary evaluation shows that these learning tools are effective in improving students'…

Keeports, David – European Journal of Physics, 2012

Macroscopic objects, although quantum mechanical by nature, conform to Newtonian mechanics under normal observation. According to the quantum mechanical correspondence principle, quantum behavior is indistinguishable from classical behavior in the limit of very large quantum numbers. The purpose of this paper is to provide an example of the…

A series of computational laboratory experiments aimed at teaching students principles of rational drug design are described and evaluated. These experiments range from an introduction to viewing protein-ligand complexes to optimizing geometries of potential drugs with quantum chemistry and automated docking. Student feedback indicates that such a…

Marshman, Emily; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2015

Compared with introductory physics, relatively little is known about the development of expertise in advanced physics courses, especially in the case of quantum mechanics. Here, we describe a framework for understanding the patterns of student reasoning difficulties and how students develop expertise in quantum mechanics. The framework posits that…

Sayer, Ryan; Maries, Alexandru; Singh, Chandralekha – Physical Review Physics Education Research, 2017

Learning quantum mechanics is challenging, even for upper-level undergraduate and graduate students. Research-validated interactive tutorials that build on students' prior knowledge can be useful tools to enhance student learning. We have been investigating student difficulties with quantum mechanics pertaining to the double-slit experiment in…

Porter, C. D.; Heckler, A.F. – Physical Review Physics Education Research, 2019

Quantum mechanics is a notoriously counterintuitive subject within physics and has been the subject of a number of studies at the undergraduate level, and a few pioneering studies at the graduate level. The sketching of wave functions in a confining well is in one sense one of the most basic activities in quantum mechanics. But in another sense,…

Baily, Charles; Finkelstein, Noah D. – Physical Review Special Topics - Physics Education Research, 2015

Most introductory quantum physics instructors would agree that transitioning students from classical to quantum thinking is an important learning goal, but may disagree on whether or how this can be accomplished. Although (and perhaps because) physicists have long debated the physical interpretation of quantum theory, many instructors choose to…

Dangur, Vered; Avargil, Shirly; Peskin, Uri; Dori, Yehudit Judy – Chemistry Education Research and Practice, 2014

Most undergraduate chemistry courses and a few high school honors courses, which focus on physical chemistry and quantum mechanics, are highly mathematically-oriented. At the Technion, Israel Institute of Technology, we developed a new module for high school students, titled "Chemistry--From 'the Hole' to 'the Whole': From the Nanoscale to…

Brown, Erin; de la Peña, Lisandro Hernández – Journal of Chemical Education, 2018

The quantum mechanics of a simplified Pöschl-Teller potential in one dimension is analyzed at an elementary level. The number of bound states of this potential is determined by a parameter "l" characterizing the depth of the potential energy. The resulting collection of potentials with varying depth, as well as their ground state…

Greca, Ileana M.; Freire, Olival, Jr. – Chemistry Education Research and Practice, 2014

Finding the best ways to introduce quantum physics to undergraduate students in all scientific areas, in particular for chemistry students, is a pressing, but hardly a simple task. In this paper, we discuss the relevance of taking into account lessons from the history of the discipline and the ongoing controversy over its interpretations and…

Körhasan, Nilüfer Didis – Educational Sciences: Theory and Practice, 2015

Quantum theory is one of the most successful theories in physics. Because of its abstract, mathematical, and counter-intuitive nature, many students have problems learning the theory, just as teachers experience difficulty in teaching it. Pedagogical research on quantum theory has mainly focused on cognitive issues. However, affective issues about…

Wall, Kathryn P.; Dillon, Rebecca; Knowles, Michelle K. – Biochemistry and Molecular Biology Education, 2015

Fluorescent proteins are commonly used in cell biology to assess where proteins are within a cell as a function of time and provide insight into intracellular protein function. However, the usefulness of a fluorescent protein depends directly on the quantum yield. The quantum yield relates the efficiency at which a fluorescent molecule converts…

de Freitas, Elizabeth; Sinclair, Nathalie – Canadian Journal of Science, Mathematics and Technology Education, 2018

Human reasoning about and with uncertainty is often at odds with the principles of classical probability. Order effects, conjunction biases, and sure-thing inclinations suggest that an entirely different set of probability axioms could be developed and indeed may be needed to describe such habits. Recent work in diverse fields, including cognitive…
