Li, Jing; Singh, Chandralekha – Physical Review Physics Education Research, 2019
We discuss an investigation of the difficulties that students in a calculus-based university introductory physics course have with electric field and the superposition principle for the case of a continuous charge distribution and how that research was used as a guide in the development, validation, and evaluation of a tutorial on these topics to…

Maries, Alexandru; Singh, Chandralekha – Physical Review Physics Education Research, 2018
Drawing appropriate diagrams is a useful problem solving heuristic that can transform a problem into a representation that is easier to exploit for solving it. One major focus while helping introductory physics students learn effective problem solving is to help them understand that drawing diagrams can facilitate problem solution. We conducted an…

Marshman, Emily; Singh, Chandralekha – Physical Review Physics Education Research, 2017
Single photon experiments involving a Mach-Zehnder interferometer can illustrate the fundamental principles of quantum mechanics, e.g., the wave-particle duality of a single photon, single photon interference, and the probabilistic nature of quantum measurement involving single photons. These experiments explicitly make the connection between the…

Good, Melanie; Marshman, Emily; Yerushalmi, Edit; Singh, Chandralekha – Physical Review Physics Education Research, 2018
Physics problems can be posed in different ways. Given a physics scenario, different problem types presenting that scenario in various ways can emphasize different instructional goals. In this investigation, we examined the views of physics graduate teaching assistants (TAs) enrolled in a semester-long TA professional development course about the…

Mason, Andrew; Singh, Chandralekha – Physics Education, 2016
The ability to categorize problems based upon underlying principles, rather than contexts, is considered a hallmark of expertise in physics problem solving. With inspiration from a classic study by Chi, Feltovich, and Glaser, we compared the categorization of 25 introductory mechanics problems based upon similarity of solution by students in large…

Sayer, Ryan; Marshman, Emily; Singh, Chandralekha – Physical Review Physics Education Research, 2016
Just-in-Time Teaching (JiTT) is an instructional strategy involving feedback from students on prelecture activities in order to design in-class activities to build on the continuing feedback from students. We investigate the effectiveness of a JiTT approach, which included in-class concept tests using clickers in an upper-division quantum…

Lin, Shih-Yin; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2015
It is well known that introductory physics students often have alternative conceptions that are inconsistent with established physical principles and concepts. Invoking alternative conceptions in the quantitative problem-solving process can derail the entire process. In order to help students solve quantitative problems involving strong…

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…

Lin, Shih-Yin; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2013
In this study, we examine introductory physics students' ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. 382 students from a calculus-based and an algebra-based introductory physics course were administered a quiz in the recitation…

Zhu, Guangtian; Singh, Chandralekha – Physical Review Special Topics - Physics Education Research, 2013
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 development and implementation of a research-based learning tool, Quantum Interactive Learning Tutorial (QuILT), to reduce these difficulties. The preliminary evaluation…

Lin, Shih-Yin; Henderson, Charles; Mamudi, William; Singh, Chandralekha; Yerushalmi, Edit – Physical Review Special Topics - Physics Education Research, 2013
As part of a larger study to understand instructors' considerations regarding the learning and teaching of problem solving in an introductory physics course, we investigated beliefs of first-year graduate teaching assistants (TAs) regarding the use of example solutions in introductory physics. In particular, we examine how the goal of promoting…

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'…

Singh, Chandralekha; Haileselassie, Daniel – Journal of College Science Teaching, 2010
Science teaching and learning can be made both engaging and student-centered using pedagogical, computer-based learning tools. We have developed self-paced interactive problem-solving tutorials for introductory physics. These tutorials can provide guidance and support for a variety of problem-solving techniques, as well as opportunities for…
