Alison Bates; Kathryn M. Williams; Ann E. Hagerman – Biochemistry and Molecular Biology Education, 2025
We created a novel laboratory experience where undergraduate students explore the techniques used to study protein misfolding, unfolding, and aggregation. Despite the importance of protein misfolding and aggregation diseases, protein unfolding is not typically explored in undergraduate biochemistry laboratory classes. Yeast alcohol dehydrogenase…

Meryssa Piper; Jessica Frankle; Sophia Owens; Blake Stubbins; Lancen Tully; Katherine Ryker – Journal of Geoscience Education, 2025
Rock and mineral labs are fundamental in traditional introductory geology courses. Successful implementation of these lab activities provides students opportunities to apply content knowledge. Inquiry-based instruction may be one way to increase student success. Prior examination of published STEM labs indicates that geology labs, particularly…

Yannik Hilla; Maximilian Stefani; Elisabeth V. C. Friedrich; Wolfgang Mack – Cognitive Research: Principles and Implications, 2025
Whether or not it is possible to predict military performance using laboratory measures constitutes an important question. There are indications that humans possess a common multitasking ability enabling them to perform complex behaviors irrespective of task requirements. Working memory processing abilities likely illustrate cognitive substrates…

Kiya Lasater; Natalie J. McDonald; Thang Tran; David Pershing – Chemical Engineering Education, 2025
This paper describes an innovative, new, laboratory experiment conceived as a Senior Capstone Project by the student authors to provide experience with heat pipes for students in our junior-year Process Laboratory course at the University of Utah. Heat pipes can transport energy over long distances with minimal temperature gradients and no moving…

Amanda Rae Buchberger; Jericha Mill – Journal of Chemical Education, 2025
The COVID-19 pandemic was an unprecedented event that, out of necessity, drastically changed the way undergraduate chemistry courses were taught. With the cancellation of in-person classes, laboratory experiences were delayed and/or moved to the virtual space, the latter keeping the general framework of the laboratory experiment but removing the…

Thai-Huy Nguyen; Maya Rabinowitz – Community College Journal of Research and Practice, 2025
The COVID-19 pandemic disrupted community colleges and created a new context in which they were forced to operate. Faculty, especially those who normally taught in-person, were required to transition quickly to fully online classrooms. Drawing on semi-structured interviews conducted at the start of the pandemic with 17 students pursuing degree…

Sabrina González; Ana Cristina S. M. Rocha – Paedagogica Historica: International Journal of the History of Education, 2025
In the first decades of the twentieth century, amidst the emergence of experimental psychology, Latin American educators became pedagogical innovators and advocates of school reforms. They used the classroom as a laboratory to study children's intelligence and collect data that could potentially improve their education. This paper traces…

Larry Collins; Alexis R. Hartley; Christopher T. Jurgenson – Journal of Chemical Education, 2025
NMR prediction using ChemDoodle, NMR calculation with Gaussian, and hands-on data collection using a benchtop NMR spectrometer were explored to assess their synergistic capacity in teaching NMR to organic chemistry students. Nine molecules representing functional groups commonly encountered in undergraduate organic chemistry were selected. Spectra…

Joseph Chiarelli; Melissa A. St. Hilaire; Brandi L. Baldock; Jimmy Franco; Stephen Theberge; Anthony L. Fernandez – Journal of Chemical Education, 2025
There is a growing need for chemistry students to be able to handle and manipulate large datasets and analyze them in an efficient and accessible way. This creates the need to develop course materials that introduce these topics early in the undergraduate curriculum. To address this growing need, this activity introduced RStudio to students…

R. A. Paggi; M. C. Ferrari; M. Cerletti; M. I. Giménez; T. S. Schwarz; A. Marchfelder; R. E. De Castro – Biochemistry and Molecular Biology Education, 2025
Perturbation of gene expression using RNA interference (RNAi) or CRISPR interference (CRISPRi) is a useful strategy to explore the function of essential genes. In the archaeon "Haloferax volcanii," the CRISPR-Cas system has been adapted as a CRISPRi tool to silence the expression of specific genes. We developed a laboratory class (LC) to…
