Corin L. Bowen – ProQuest LLC, 2021
This thesis contains two areas of research. The first part contributes to the field of engineering mechanics. This research investigates the thermomechanical shape memory behavior of shape memory alloy (SMA) springs. As SMA springs undergo stress- and/or temperature-induced phase transformation, they experience varying combinations of axial,…

Iwuanyanwu, Paul Nnanyereugo – Journal of Education in Science, Environment and Health, 2019
The present study explores students' understanding of calculus-based kinematics (henceforth, CBK), in which argumentation is taken as the sequence of the modes of fostering reasoning and problem-solving. The investigation stresses the importance of arguments students bring to the learning situation of CBK and recognizes the active construction of…

Miller, Andrew; Gift, Alan – Journal of Chemical Education, 2019
A service-learning project was completed in both a senior and sophomore-level analytical chemistry course. Both projects took place at a local wetland managed by a nonprofit volunteer group. The two classes performed an in-depth water quality analysis and soil/sediment extractions examining the spatial variation of nutrients. The senior-level…

Fung, Fun Man; Watts, Simon Francis – Journal of Chemical Education, 2019
The redesign of an advanced analytical and physical chemistry practical module for senior undergraduates is described in this report. The underpinning rationale for the changes is to use cooperative learning groups placed in situations beyond their previous experience to increase the student experience of Kolb's Learning Cycle to a level greater…

Ortiz Lechuga, Eugenia Guadalupe; Tovar Herrera, Omar Eduardo; Arévalo Niño, Katiushka – Biochemistry and Molecular Biology Education, 2019
In this work, we present the results of an undergrad student from the perspective of its first approach as a principal researcher in a project. In order to gain practical experience, one of the options for students that have interest in pursuing a postgraduate program corresponds to a research stay in a laboratory of their selected field…

Johnson, Josiah W.; Mitchell, Christian D.; Deloach, Anna M.; Simpson, Hannah E.; Dunlap, Tori B. – Journal of Chemical Education, 2019
Protein structure, function, and signaling are a large portion of biochemistry. Because of this, proteins are often used as model systems in biochemistry laboratory courses, where a course-long project might comprise protein expression, purification, and characterization. Two common protein expression methods are isopropyl…

Cooper, Melanie M.; Stowe, Ryan L.; Crandell, Olivia M.; Klymkowsky, Michael W. – Journal of Chemical Education, 2019
The fundamental structure of a typical mainstream two-semester organic chemistry course, populated mostly by life science majors and taught at universities throughout the United States, has changed little since the 1970s. However, much of the research on learning in organic chemistry has been devoted to characterizing student difficulties of…

Contreras-Cruz, David A.; Cantú-Reyes, Margarita; García-Sánchez, Juan M.; Peña-Ortíz, Daniel; Sánchez-Carmona, Miguel A.; Miranda, Luis D. – Journal of Chemical Education, 2019
A photochemical reactor was tested in an undergraduate teaching laboratory through the environmentally friendly aromatization of a 1,4-dihydropyridine, successfully using air as an oxidant, organic dye fluorescein as a photosensitizer, and sodium carbonate as a base. This experiment allowed students to be taught key concepts of photochemistry,…

Liu, Yujuan; Myers, Emily J.; Rydahl, Stephanie A.; Wang, Xisen – Journal of Chemical Education, 2019
An instructional research-like multiweek laboratory project for a second-semester introductory general chemistry laboratory course has been developed. The ultrasonic-assisted synthesis method using low cost commercial ultrasonic cleaners has the convenience of running multiple students' reactions simultaneously. Taking advantage of short reaction…

Aubrecht, Katherine B.; Bourgeois, Marie; Brush, Edward J.; MacKellar, Jennifer; Wissinger, Jane E. – Journal of Chemical Education, 2019
Chemistry educators have a responsibility to teach students about the essential role the field of chemistry has in a sustainable future for the planet. Chemical products, such as pharmaceuticals, plastics, electronics, agrochemicals, and building materials, all benefit society yet unintended consequences resulting from the production and use of…

Ernawati, M. Dwi Wiwik; Muhammad, Damris; Asrial, Asrial; Muhaimin, Muhaimin – International Journal of Evaluation and Research in Education, 2019
Creative thinking is needed in 21st century learning. This quantitative study aimed to determine whether chemistry education students at Universitas Jambi have the initial ability of creative thinking. The type of research that is used is a research design survey that is strengthened by the results of interviews to support the results of…

Mullins, Joseph J.; Prusinowski, Allen F. – Journal of Chemical Education, 2019
A microwave-promoted synthesis of a carbocyclic curcuminoid has been developed for the undergraduate organic chemistry laboratory curriculum. The experiment features several teaching points: A novel Knoevenagel iminium-mediated condensation forms a highly conjugated, intensely colored natural product. Reaction occurs uniquely at the less acidic…

Malinak, Steven M.; Hertzog, Jerald E.; Pacilio, Julia E.; Polvani, Deborah A. – Journal of Chemical Education, 2019
Laboratory experiments that offer interdisciplinary experiences for students are appealing and are increasingly popular additions to undergraduate chemistry curricula. Students can capitalize on their knowledge of multiple areas of chemistry while working through an application, and this fosters the development of progressive problem-solving…

Miquet, Johanna G.; González, Lorena; Sotelo, Ana I.; González Lebrero, Rodolfo M. – Biochemistry and Molecular Biology Education, 2019
Enzyme kinetics is an essential topic in undergraduate Biochemistry courses. A laboratory work that covers the principal basic concepts of enzyme kinetics in steady state is presented. The alkaline phosphatase catalyzed reaction of phenyl-phosphate hydrolysis was studied as a model. The laboratory experience was designed to reinforce the concepts…
