Scowcroft, Victoria; Davies, Steve R.; Mathlin, Gary; Sloan, Peter A. – Physics Education, 2023
Astronomy is one of the few sciences where the data (star-light) can be seen by all. Yet, there is a disconnect between a typical undergraduate lecture and, for example, where a planet may be in the sky and how to observe it. With the advent of moderate cost, high-quality 'back-garden' astronomy, and standard computers powerful enough to produce…

Matthew Clemson; Alice Huang; Gareth Denyer; Maurizio Costabile – Biochemistry and Molecular Biology Education, 2025
The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

Cryogenic electron microscopy (cryo-EM) is a powerful technique capable of characterizing large protein complexes that are otherwise impossible to characterize using traditional crystallography methods. Cryo-EM has played a pivotal role in our understanding of the structure--function relationship of the spike proteins on the COVID-19 viral…

Killian, Benjamin J.; Singletary, Steven – Journal of Chemical Education, 2022
We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…

Christine E. Bell; Oana Birceanu – Advances in Physiology Education, 2025
One of the identified points of confusion and a barrier to students using generative artificial intelligence (GenAI) is knowing what their professor would consider appropriate use of GenAI in a classroom setting or course framework. This creates points of friction for instructors and students as they try to navigate an ever-changing landscape,…

Sedky, Nada K.; Arafa, Reem K. – Biochemistry and Molecular Biology Education, 2022
Nowadays, novel Biochemistry lab techniques are being introduced at a very fast pace in scientific research. This requires development of new labs for undergraduate Biochemistry courses to equip the students with up-to-date techniques. However, the time limit of Biochemistry labs for undergraduate students represents a major obstacle. This article…

Cynthia Y. Delgado; Richard E. Mayer – Journal of Educational Computing Research, 2025
This study examined whether answering focused explanative questions during pauses in an immersive virtual reality (IVR) lesson on pipetting procedures could enhance learning. The goal was to take a generative learning activity, known to be effective for declarative knowledge with conventional media, to the context of procedural knowledge with…

Navarre, Edward C. – Journal of Chemical Education, 2020
A simple computer interface for controlling a compact spectrograph for use as a spectrophotometer in an undergraduate teaching laboratory was developed. The project was implemented on a Raspberry Pi computer which permits the integration of a light source into the software. The interface was written in Python to facilitate modification by the user…

Kosenkov, Yana; Kosenkov, Dmitri – Journal of Chemical Education, 2021
A novel technology that employs computer vision (CV) to carry out an automatic titration experiment is presented. The experiment is designed to facilitate understanding of the basics of the CV technology and its application in chemistry among undergraduate students. The standard chemical procedure of titration has been chosen, since it is…

Wehrbein, William M. – Physics Teacher, 2022
Recognized as one of the most beautiful experiments of all time, the oil drop experiment performed by Robert Millikan and his graduate students (primarily Harvey Fletcher) is a standard in the repertoire of experiments performed by undergraduate physics students. However, "as a teaching lab it does not enjoy a good reputation for three…

Biswas, Subhrajyoti; Roy, Durjoy – Physics Education, 2022
At constant current (I) the forward bias potential (V) of a "pn" junction diode may be considered to vary linearly with temperature (t) within a temperature range. Based on this property we have constructed diode thermometer using germanium (Ge) and silicon (Si) diodes. The experimental "V-t" data at constant forward current…

Baker, Blane; Sherer, Maggie; Mossinghoff, Ben; Laycock, Will – Physics Teacher, 2022
A wood cantilever of length ~2.5 m is driven into resonance using the hand as a simple driver. Video recordings of these oscillations are analyzed to determine experimental second harmonic (n = 2) damped resonance frequencies. These frequencies are compared to theoretical ones, obtained from measurements of elastic moduli, damping properties, and…

In modern education, mobile applications offer flexibility for learning anytime and anywhere, yet biochemistry lacks mobile-based virtual laboratories. This study aimed to develop a 2D Mobile-Based Virtual Laboratory Simulation (2D-MViLS) for blood glucose level measurement and evaluate its impact on pharmacy students' learning experience. In…

Miguel Ángel Rodriguez-Florido; José Juan Reyes-Cabrera; Aday Melián; Carmen Nieves Hernández-Flores; Juan Ruiz-Azola; Manuel Maynar – Journal of New Approaches in Educational Research, 2024
The metaverse is known as the hypothetical iteration of the Internet as a single, connected, universal and immersive virtual world that can be accessed via immersive technology devices. One approach to this concept can be achieved through the use of multi-user immersive virtual reality applications. Immersive virtual reality (IVR), which uses…

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…
