Recommendations for the use of notebooks in upper-division physics lab courses
Jacob T. Stanley, H. J. Lewandowski
The use of lab notebooks for scientific documentation is a ubiquitous part of physics research. However, it is common for undergraduate physics laboratory courses not to emphasize…
Developing skills vs reinforcing concepts in physics labs: Insight from E-CLASS
Bethany R. Wilcox, H. J. Lewandowski
Physics laboratory courses have been generally acknowledged as an important component of the undergraduate curriculum, particularly with respect to developing students' interest in…
Electronics lab instructors' approaches to troubleshooting instruction
Dimitri R. Dounas-Frazer, H. J. Lewandowski
In this exploratory qualitative study, we describe instructors' self-reported practices for teaching and assessing students' ability to troubleshoot in electronics lab courses. We…
Impact of instructional approach on students' epistemologies about experimental physics
Bethany R. Wilcox, H. J. Lewandowski
Student learning in undergraduate physics laboratory courses has garnered increased attention within the PER community. Considerable work has been done to develop curricular materi…
Open-ended versus guided laboratory activities: Impact on students' beliefs about experimental physics
Bethany R. Wilcox, H. J. Lewandowski
Improving students' understanding of the nature of experimental physics is often an explicit or implicit goal of undergraduate laboratory physics courses. However, lab activities i…
Collapse and revival of the monopole mode of a degenerate Bose gas in an isotropic harmonic trap
C. J. E. Straatsma, V. E. Colussi, M. J. Davis +5
We study the monopole (breathing) mode of a finite temperature Bose-Einstein condensate in an isotropic harmonic trap recently developed by Lobser et al. [Nat.~Phys., \textbf{11},…
Nothing works the first time: An expert experimental physics epistemology
Dimitri R. Dounas-Frazer, H. J. Lewandowski
The ability to troubleshoot is an important learning outcome for undergraduate physics laboratory courses. To better understand the role of troubleshooting in electronics laborator…
Research-based assessment of students' beliefs about experimental physics: When is gender a factor?
Bethany R. Wilcox, H. J. Lewandowski
The existence of gender differences in student performance on conceptual assessments and their responses to attitudinal assessments has been repeatedly demonstrated. This differenc…
Lab notebooks as scientific communication: investigating development from undergraduate courses to graduate research
Jacob T. Stanley, H. J. Lewandowski
In experimental physics, lab notebooks play an essential role in the research process. For all of the ubiquity of lab notebooks, little formal attention has been paid to addressing…
Investigating the role of model-based reasoning while troubleshooting an electric circuit
Dimitri R. Dounas-Frazer, Kevin L. Van De Bogart, MacKenzie R. Stetzer +1
We explore the overlap of two nationally-recognized learning outcomes for physics lab courses, namely, the ability to model experimental systems and the ability to troubleshoot a m…
Alternative model for the administration and analysis of research-based assessments
Bethany R. Wilcox, Benjamin M. Zwickl, Robert D. Hobbs +3
Research-based assessments represent a valuable tool for both instructors and researchers interested in improving undergraduate physics education. However, the historical model for…
