Pasachoff, Jay M.; Mativi, Jason W. – Physics Teacher, 2020
To span the great distance from the solar system to the farthest clusters of galaxies in the universe, astronomers break down the distance indicators into steps. The nearest ones are measured geometrically, with what is known as parallax. Among the objects whose distances are thus directly measured are a rare type of star known as a Cepheid…

Cranwell, Philippa B.; Page, Elizabeth M. – New Directions in the Teaching of Physical Sciences, 2020
The use of a group-based approach to project working has been shown to provide significant advantage to students in terms of project outcomes, motivation and engagement. The Department of Chemistry at the University of Reading has recently explored the use of group projects for final year practical work. In this model, students are presented with…

Sirnoorkar, Amogh; Mazumdar, Anwesh; Kumar, Arvind – Physical Review Physics Education Research, 2020
We elaborate on a new approach of assessing content-based epistemic clarity of college physics students in terms of their ability to discriminate between different epistemic warrants for propositions in a chained argument in physics. A threefold classification (nominal, physical, and mathematical) of warrants is used, with each class split into a…

Saparullah; Purwanto, Agus; Wisnuwijaya, Rhyko Irawan; Sari, Emi Kurnia; Dwandaru, Wipsar Sunu Brams – Physics Education, 2020
The objective of this study is to design a temperature measurement system based on a non-contact method using a sensor camera from a webcam. The material being measured is nickel wire given an electrical current of 4.5 A-6.5 A with an interval of 0.5 A. The temperature measurement is based upon the measurement of the average pixel value…

Smith, Emily M.; Stein, Martin M.; Holmes, N. G. – Physical Review Physics Education Research, 2020
Many instructional physics labs are shifting to teach experimentation skills, rather than to demonstrate or confirm canonical physics phenomena. Our previous work found that many students engage in questionable research practices in attempts to confirm the canonical physics phenomena, even when confirmation is explicitly not the goal of the lab.…

Hepworth, Katherine; Ivey, Cesunica E.; Canon, Chelsea; Holmes, Heather A. – Journal of Geoscience Education, 2020
An interdisciplinary undergraduate atmospheric science modeling course was cotaught at a midsize public university by three professors from atmospheric science, statistics, and design using a blended learning approach. The in-class portion of the course taught upper-level students numerical weather prediction modeling and statistical evaluation…

Gjerde, Vegard; Holst, Bodil; Kolstø, Stein Dankert – Physical Review Physics Education Research, 2020
Introductory physics is taught to several hundred thousand university students every year. It is seen as especially difficult by many and the failure rate is often high. A relevant question is whether one can increase the success rate among the weaker students? Retrieval practice is an established learning strategy with large benefits. However, as…

Kottmeyer, Alexa M.; Van Meter, Peggy; Cameron, Chelsea – Advances in Physiology Education, 2020
College biology courses commonly use diagrams to convey information. These visual representations are embedded in course materials with the expectation that students can comprehend and learn from them. Educational research, however, suggests that many students have difficulty understanding diagrams and the conventions (e.g., labels, arrows) they…

Vemu, Sheela; McDonald, Jeanne Gillespie; León-Valderrama, Nidia Vanessa – Intersection: A Journal at the Intersection of Assessment and Learning, 2020
A process for adapting a case study as a high impact practice for undergraduate microbiology classes is described and its use in assessing global awareness as an institutional outcome at the course level. Documenting the student learning of content objectives and retention is addressed. Four student artifacts are assessed with an adaption of…

Beatty, Abby E.; Driessen, Emily P.; Gusler, Taylor; Ewell, Sharday; Grilliot, Amy; Ballen, Cissy J. – CBE - Life Sciences Education, 2021
While science has profound social impacts, we often teach biology as removed from societally debated issues. Here, we address this gap in biology education through the implementation of novel materials that promote ideological awareness (IA). Using mixed-method analyses, we explore students' perceptions of the relationship between science and…

Hung, Hui-Chun; Young, Shelley Shwu-Ching – Australasian Journal of Educational Technology, 2021
The emergence of open online courses and flipped classrooms has brought new opportunities to unbundle the traditional university. This study aimed to investigate a thermal physics classroom integrated with an open online learning mode to afford various learning strategies for students in Taiwan. Moreover, we examined students' preferred learning…

Rabin, Jeffrey M.; Burgasser, Adam; Bussey, Thomas J.; Eggers, John; Lo, Stanley M.; Seethaler, Sherry; Stevens, Laura; Weizman, Haim – International Journal of STEM Education, 2021
Rate of change concepts from calculus are presented and applied rather differently in college mathematics, physics, biology, and chemistry classes. This is not simply a matter of pedagogical style but reflects real cultural differences between these disciplines. We describe the efforts of our interdisciplinary collaboration to understand and…

To investigate patterns of gender-based performance gaps, we conducted a meta-analysis of published studies and unpublished data collected across 169 undergraduate biology and chemistry courses. While we did not detect an overall gender gap in performance, heterogeneity analyses suggested further analysis was warranted, so we investigated whether…

Welleford, Andrew S.; Weaver, Lauren M.; Platt, Kristen M. – HAPS Educator, 2021
Engagement of multiple learning modalities has been shown to promote learning. This study aimed to develop resources for anatomical sciences educators interested in adding additional teaching modalities into their repertoire. Three review sessions were created for the muscle anatomy unit of an undergraduate anatomy and physiology course, each…

He, Zhiyu; Ding, Shansen; Wang, Luyang; Wang, Guoqing; Liang, Xingguo; Takarada, Tohru; Maeda, Mizuo – Journal of Chemical Education, 2021
Demonstration of a colorimetric approach for nucleic acid detection represents an attractive educational experiment for chemistry undergraduate students in the time of coronavirus pandemic. Herein, a rapid and vivid detection method that visualizes the presence of a specific DNA sequence is described. The plasmon resonance of gold nanoparticles…
