Direct linkRana, K. P. S.; Kumar, Vineet; Mendiratta, Jatin – European Journal of Engineering Education, 2017
One of the most elementary concepts in freshmen Electrical Engineering subject comprises the Resistance-Inductance-Capacitance (RLC) circuit fundamentals, that is, their time and frequency domain responses. For a beginner, generally, it is difficult to understand and appreciate the step and the frequency responses, particularly the resonance. This…

Robinson, Rebekah L.; Neely, Amy E.; Mojadedi, Wais; Threatt, Katie N.; Davis, Nicole Y.; Weiland, Mitch H. – Biochemistry and Molecular Biology Education, 2017
The concepts of protein purification are often taught in undergraduate biology and biochemistry lectures and reinforced during laboratory exercises; however, very few reported activities allow students to directly gain experience using modern protein purification instruments, such as Fast Protein Liquid Chromatography (FPLC). This laboratory…

Mowry, Curtis; Milofsky, Rob; Collins, William; Pimentel, Adam S. – Journal of Chemical Education, 2017
This laboratory introduces students to laser-induced breakdown spectroscopy (LIBS) for the analysis of metals in soil and rock samples. LIBS employs a laser-initiated spark to induce electronic excitation of metal atoms. Ensuing atomic emission allows for qualitative and semiquantitative analysis. The students use LIBS to analyze a series of…

Noll, Robert J.; Fitch, Richard W.; Kjonaas, Richard A.; Wyatt, Richard A. – Journal of Chemical Education, 2017
A kinetic isotope effect (KIE) experiment is described for the physical chemistry laboratory. Students conduct a hypochlorite (household bleach) oxidation of an equimolar mixture of 1-phenylethanol and 1-deuterio-1-phenylethanol to acetophenone. The reaction occurs in a biphasic reaction mixture and follows first-order kinetics with respect to…

Bopegedera, A. M. R. P.; Coughenour, Christopher L.; Oswalt, Andrew J. – Journal of Chemical Education, 2016
Limonite is the field term for a mixed assemblage of ferric oxyhydroxides, often containing nonferric silicate impurities. It is abundant on Earth's surface, possesses variable iron content, and is easily recognized by distinctive yellow and ochre hues. Limonite is a unique centerpiece for undergraduate chemistry laboratories because each sample…

Wilkinson, Shane M.; Sheedy, Timothy M.; New, Elizabeth J. – Journal of Chemical Education, 2016
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…
