Transcription is the critical first step in expressing a gene, during which an RNA polymerase (RNAP) synthesizes an RNA copy of one strand of the DNA that encodes a gene. Here we describe a laboratory experiment that uses a single assay to probe two important steps in transcription: (1) RNAP binding to DNA, and (2) the transcriptional activity of…

Jones, Eric; Glanz, Hunter; Wilkinson, Steven; Fogle, Emily – Biochemistry and Molecular Biology Education, 2023
Course-based undergraduate research experiences (CUREs) can provide undergraduate students access to research opportunities when student and faculty resources are limited. In addition to expanding research opportunities, CUREs may also be explored as a pedagogical tool for improving student learning of course content and laboratory skills, as well…

Hands-on courses utilizing preserved human tissues for educational training offer an important pathway to acquire basic anatomical knowledge. Owing to the reevaluation of formaldehyde limits by the European Commission, a joint approach was chosen by the German-speaking anatomies in Europe (Germany, Austria, Switzerland) to find commonalities among…

Lai, Emily R.; Rukavina, Nadia A.; Wisco, Jonathan J.; Zumwalt, Ann C. – Anatomical Sciences Education, 2023
The anatomy laboratory can incite strong emotional reactions in students, which can in turn facilitate growth in empathy, care for vulnerable others, and professionalism. Despite this, little is known about the relative emotional impacts of different laboratory modalities. The response to the COVID-19 pandemic created an opportunity to compare the…

The correlation of anatomy with pathophysiology is not intuitive for many medical students. Despite detailed cadaver dissections and three-dimensional models, board-style clinical correlation questions can still be challenging for first-year students. To facilitate understanding in this regard, prosections were developed to illustrate the clinical…

Purpose: Acoustic and perceptual quantification of vocal strain has been a vexing problem for years. To increase measurement rigor, a suitable single-variable matching stimulus for strain was developed and validated, based on the matching stimulus used previously for breathy and rough voice qualities. Method: A set of 21 comparison stimuli for a…

Tang, Hengtao; Arslan, Okan; Xing, Wanli; Kamali-Arslantas, Tugba – Journal of Computing in Higher Education, 2023
Socially shared metacognition is important for effective collaborative problem solving in virtual laboratory settings, A holistic account of socially shared metacognition in virtual laboratory settings is needed to advance our understanding, but previous studies have only focused on the isolated effect of each dimension on problem solving. This…

Postsession narrative notes written by professional tutors in a health sciences university writing center had never been analyzed to identify the most common elements noted as subpar in graduate students' scholarly writing. The purpose of this basic qualitative study was to examine these notes to identify the most common elements noted as subpar…

This dissertation investigates the experiences of multilingual writers in a writing center at a major research university based in the United States. It includes interviews with the writers and with the tutors who serve multilingual writers, to understand if these writers are getting what they need in the writing center to be successful in their…

The global COVID-19 emergency disrupted educational systems and created internship crises for universities and students. In response, one west coast social work program's practicum education department developed virtual, interactive labs that addressed the Grand Challenges (GCs), increased interdisciplinary collaboration, and ensured the…

Ready, Set, Go? Impact of the Pandemic on Student Readiness: Laboratories, Preparedness, and Support
Jennifer Garcia Ramos; Marcy H. Towns – Journal of Chemical Education, 2023
There is little doubt that the pandemic has had a significant impact on students' academic achievement and mental health across the K-16 spectrum. For undergraduate chemistry instructors, data on the number of laboratories students completed in high school and in what mode would be important information in considering what modifications could be…

An active-learning approach was employed in a project for our chemistry major students on the synthesis of biodiesel (BD) from an Amazon region oil. The project, involving activities in class and in the laboratory, was given during 8 weeks of the spring semester of 2022. The students were asked about their previous contact with the synthesis and…

We have developed a guided-inquiry laboratory exercise in which students perform viscosity measurements to infer the structure of poly(vinyl alcohol) (PVA) in aqueous solution. The activity combines both experiments and modeling. In the experimental portion of the exercise, students measure the viscosity of several solutions of PVA with differing…

This experiment demonstrates that copper(II) chloride dihydrate (CuCl[subscript 2]·2H[subscript 2]O) in different solvents (acetone, isopropyl alcohol, or water) displays divergent colors and visible-near IR spectra. Both the reactions of these solutions with 2 equiv of sodium hydroxide (NaOH) and the direct solid-state reaction of CuCl[subscript…

Electrophilic aromatic substitution reactions are common in the organic chemistry laboratory. These reactions, while ubiquitous, use corrosive reagents and halogenated or hydrophobic solvents that produce expensive and hazardous waste streams. The carboxylation of phenols (Kolbe-Schmitt reaction), although aqueous, typically involves conditions…
