Supporting physics instructors to use a variety of evidence-based approaches to improve student learning: An example from quantum mechanics
Paul Justice, Emily Marshman, Chandralekha Singh
Physics instructors need support to successfully adopt and adapt evidence-based active engagement (EBAE) approaches because improving teaching and learning is a process and support…
Using multiple representations to improve student understanding of quantum states
Emily Marshman, Alexandru Maries, Chandralekha Singh
One hallmark of expertise in physics is the ability to translate between different representations of knowledge and use the representations that make the problem-solving process ea…
Challenges in addressing student difficulties with basics and change of basis for two-state quantum systems using a multiple-choice question sequence in online and in-person classes
Peter Hu, Yangqiuting Li, Chandralekha Singh
Research-validated multiple-choice questions comprise an easy-to-implement instructional tool for scaffolding student learning and providing formative assessment of students' knowl…
Statistically equivalent models with different causal structures: An example from physics identity
Yangqiuting Li, Chandralekha Singh
Structural equation modeling (SEM) is a statistical method widely used in educational research to investigate relationships between variables. SEM models are typically constructed…
