TA-designed vs. research-oriented problem solutions
Shih-Yin Lin, Chandralekha Singh, William Mamudi +2
In order to study graduate teaching assistants (TAs) beliefs and values about the design of instructor problem solutions, twenty-four TAs were provided with different solutions and…
Improving Students' Understanding of Quantum Mechanics by Using Peer Instruction Tools
Chandralekha Singh, Guangtian Zhu
Quantum mechanics is a challenging subject, even for advanced undergraduate and graduate students. Here, we discuss the development and evaluation of research-based concept tests f…
Students' Difficulties with Equations involving Circuit Elements
Jing Li, Chandralekha Singh
We discuss an investigation exploring students' difficulties with equations involving resistance, capacitance and inductance. We find that introductory physics students have great…
Developing a Magnetism Conceptual Survey and Assessing Gender Differences in Student Understanding of Magnetism
Jing Li, Chandralekha Singh
We discuss the development of a research-based conceptual multiple-choice survey related to magnetism. We also discuss the use of the survey to investigate gender differences in st…
Should Students be Provided Diagrams or Asked to Draw Them While Solving Introductory Physics Problems?
Alex Maries, Chandralekha Singh
Drawing appropriate diagrams is a useful problem solving heuristic that can transform a given problem into a representation that is easier to exploit for solving it. A major focus…
Probing Student Understanding With Alternative Questioning Strategies
Jeffrey M. Hawkins, Brian W. Frank, John R. Thompson +2
Common research tasks ask students to identify a correct answer and justify their answer choice. We propose expanding the array of research tasks to access different knowledge that…
