In order for undergraduate laboratory experiments to reflect modern research practice, it is essential that they include a range of elements, and that synthetic tasks are accompanied by characterization and analysis. This intermediate general chemistry laboratory exercise runs over 2 weeks, and involves the preparation of a Schiff base ligand and…

Pirinelli, Alyssa L.; Trinidad, Jonathan C.; Pohl, Nicola L. B. – Journal of Chemical Education, 2016
Polyacrylamide gel electrophoresis (PAGE) is commonly taught in undergraduate laboratory classes as a traditional method to analyze proteins. An experiment has been developed to teach these basic protein gel skills in the context of gluten protein isolation from various types of wheat flour. A further goal is to relate this technique to current…

Barcena, Homar; Chen, Peishan – Journal of Chemical Education, 2016
Students are introduced to spectrophotometry in comparing the antioxidant activity of pure eugenol and oil of cloves from a commercial source using a modified ferric reducing antioxidant power (FRAP) assay. The extraction of the essential oil from dried cloves is demonstrated to facilitate discussions on green chemistry. The anesthetic properties…

Hwang, Wu-Yuin; Purba, Siska Wati Dewi – Asia-Pacific Education Researcher, 2022
The Ubiquitous-Physics (U-Physics) app was upgraded to help students in learning inclined plane concepts. The new version of U-Physics allows students to see the experimental data not only in a graphical representation but also in a tabular representation. U-Physics provides a whiteboard function to support data explanations. The study…

Attardi, Stefanie M.; Mintz, Noah M.; Rogers, Kem A. – Anatomical Sciences Education, 2022
Online teachers are an under-researched population, but their perspectives are crucial to the successful implementation of online education. A fully online section of an established face-to-face (F2F) two-semester undergraduate anatomy course with a prosection laboratory commenced in 2012 at The University of Western Ontario, Canada. Professors'…

Digital tools and platforms offer new solutions to design and conduct university teaching. This case illustrates how such digital solutions may be utilized in problem-based learning programmes within life science educations. Specifically, the case evaluated the use of live-streamed and recorded lectures, the incorporation of digital formative…

Instructor Talk--noncontent and nonlogistical language that is focused on shaping the classroom learning environment--is a recently defined variable that may play an important role in how undergraduates experience courses. Previous research characterized Instructor Talk used by faculty teaching in biology lecture classrooms. However, graduate…

Andrade, Eric Francelino; Zaine Teixeira Debortoli, Gabriele; Gomes Batista, Victor Luiz; Newton Bizetto Meira de Andrade, James; Orlando, Débora Ribeiro; Rocha Lobo-Junior, Adalfredo – Journal of Biological Education, 2022
Learning the physiology of the cardiovascular system can be difficult for students, but the use of active teaching methodologies can help and enhance learning. To facilitate the understanding of how the cardiovascular system works, we built a functional model for Veterinary Medicine students attending a cardiovascular physiology lecture and…

Chiew, Fei Ha; Noh, Narita; Oh, Chai Lian; Noor, Nur Asmaliza Mohd; Isa, Che Maznah Mat – Asian Journal of University Education, 2022
The COVID-19 pandemic has brought about a true challenge to students and educators in the teaching, learning and assessment (TLA) of the psychomotor domain integral in laboratory experiment and design work. The pandemic has opened venues for open distance learning (ODL) with a completely new outlook for educators. The objective of this paper is to…

Stuart T. Guthrie – ProQuest LLC, 2022
This study was designed to produce a model for creating an affordable digital learning laboratory on a K-12 school campus. The need for a digital learning space is directly derived from the struggles of K-12 students to produce such objects during the COVID-19 global pandemic. This project outlines the recommended planning phases that can…

Jessica Robbins; Jaclyn M. Wells – Writing Center Journal, 2022
This article presents findings from an IRB- approved study about tutors' online information on writing center websites, scheduling systems, and social media. The study used surveys to investigate students' responses to tutors' online information and focus groups to investigate tutors' rationale for the information they shared. While many…

Graciela Arizmendi González; María del Carmen González Videgaray – Writing Center Journal, 2022
This study investigates postgraduate (PGs) and faculty needs concerning academic writing (AW) tutors' qualifications in an English as a Foreign Language (EFL) context. Tutors are the core element of a writing center (WC) (Hays, 2010). These professionals listen to (Burns, 2014), advise, and exchange information (Reid, 1993, in Hays, 2010)…

Olivia M. Reynolds – ProQuest LLC, 2022
Active learning is widely recognized as superior to traditional passive, lecture-based techniques for fostering learning in STEM courses. Interactive, hands-on learning where students interact with their peers and physical systems is an effective type of active learning. As the need for scientists and engineers continues to grow, understanding and…
