Tran, Jennifer B.; McCoy, Julia C.; Bailey, Lori M.; McDaniel, Brody P.; Simon, Ryan L.; Marchetti, Barbara; Karsili, Tolga N. V. – Journal of Chemical Education, 2020
Molecular photochemistry is an integral field in chemistry. Despite this, it is often difficult to demonstrate an effective hands-on experiment that offers a unique opportunity to students to observe photochemistry in action. Although simple laboratory experiments which use a UV-vis wavelength lamp do provide some photochemical information, the…

MacKellar, Jennifer J.; Constable, David J. C.; Kirchhoff, Mary M.; Hutchison, James E.; Beckman, Eric – Journal of Chemical Education, 2020
Although principles and practices of green and sustainable chemistry have been articulated for more than 20 years, they have yet to become systemically infused into the undergraduate chemistry curriculum. The American Chemical Society Green Chemistry Institute (ACS GCI) has convened stakeholders from across the chemistry education community to…

Simões, Manuel; Malcata, F. Xavier – Journal of Chemical Education, 2020
A laboratory experiment is described in which students carry out immobilization of the enzyme invertase via entrapment in alginate (Ca-alginate) and, accordingly, estimate values for kinetic constants and mass transfer coefficients. Immobilization of enzymes, or confinement thereof to a defined space with retention of most catalytic activity, is…

Bolay, Austin L.; Hiester, William; Davis, Nicole Y.; Weiland, Mitch H. – Journal of Chemical Education, 2020
Polymers are ubiquitous and essential to modern society, which is why the American Chemical Society has mandated inclusion of polymer chemistry in the undergraduate curriculum. To meet this requirement, we have chosen to weave a polymeric theme through multiple laboratory courses beginning with organic chemistry, where students use aspartic acid…

Joos, Bjorn; Van Bael, Marlies K.; Hardy, An T. – Journal of Chemical Education, 2020
A eutectic system is a mixture of two or more substances, displaying a melting temperature lower than its standalone components. The eutectic composition displays the lowest melting temperature of all mixtures. Typically, a eutectic system is used as an example of binary phase diagrams to demonstrate to undergraduate students. Herein, the liquidus…

Aguirre-Mendez, Claudia; Chen, Ying-Chih; Terada, Takeshi; Techawitthayachinda, Ratrapee – Journal of Chemical Education, 2020
Argumentative writing advances students' understanding of scientific concepts, ability to communicate, and scientific literacy. However, it remains unclear which components of argumentative writing drive such advancement. Further, most studies on argumentative writing have focused on students majoring in science, rather than in the nonsciences.…

Archila, Pablo Antonio; Molina, Jorge; de Mejía, Anne-Marie Truscott – Research in Science Education, 2020
Contrary to the situation at primary, middle, and secondary school levels, university science courses provide students with very few opportunities to reflect upon the nature of science (NOS). The first goal of this study was to provide evidence that the co-construction of evolutionary trees, an important component of university biology education,…

Oliveira, Alandeom W.; Bretzlaff, Tiffany; Brown, Adam O. – Research in Science Education, 2020
The present study examines the exemplification practices of a university biology instructor during a semester-long course. Attention is given specifically to how the instructor approaches "memorable exemplification"--classroom episodes identified by students as a source of memorable learning experiences. A mixed-method research approach…

Rodriguez, Jon-Marc G.; Bain, Kinsey; Towns, Marcy H. – International Journal of Research in Undergraduate Mathematics Education, 2020
Mathematics is used in the physical sciences to describe and model phenomena, resulting in a unique interface between mathematics and disciplines such as chemistry and physics. This paper focuses on themes emerging from a larger project that investigated how students understand and use mathematics in chemical kinetics, a field of study concerned…

Britson, Carol A. – HAPS Educator, 2020
Providing word banks for human anatomy and physiology lab practicals is uncommon because instructors want to avoid cueing effects, but there is little published data on their effects on student performance. In the 2016-2017 academic year, word banks were not provided for students taking lab practicals in Anatomy and Physiology I and II while in…

Vroom Redden, Alexis M.; Barton, Callie M.; William, Kyle R. – Journal of Chemical Education, 2020
Guided inquiry is the practice of allowing students to come to their own conclusions about a set of data instead of verifying a known result using a given experimental procedure. Open inquiry takes this idea one step further by allowing students to develop their own experiment and then analyze the data to arrive at a conclusion. To expose upper…

Koudehi, Masoumeh Foroutan; Zibaseresht, Ramin – Journal of Chemical Education, 2020
Suzuki-Miyaura coupling reactions are well-known among the most versatile catalytic C-C bond formation reactions. Two different routes of C-C bond Suzuki-Miyaura coupling reactions for the undergraduate organic chemistry laboratory courses have been designed and explained. A two-step reaction involving a catalyst preparation as the first step and…

Verma, Abha; Goyal, Navneet – Journal of Chemical Education, 2020
A new two-step experiment has been designed and developed for the curriculum of the Organic Chemistry Laboratory 2 (CHEM2240L) sophomore course at Xavier University of Louisiana, in New Orleans. Initially, cyclohexanol was converted to cyclohexanone using bleach as the oxidizing agent followed by the formation of the cyclohexanone oxime. However,…

Pulukuri, Surya; Abrams, Binyomin – Biochemistry and Molecular Biology Education, 2020
In order to succeed in biochemistry, students must transfer and build upon their understanding of general chemistry and introductory biology concepts. One such critical area of knowledge is bioenergetics. Student misconceptions around energy and free energy must be addressed prior to learning more advanced topics, such as energy flow in metabolic…

Emrani, Jahangir; Ahmed, Maryam; Newman, Robert H.; Thomas, Misty D.; Mowa, Chishimba Nathan; Teleha, John – Journal of Chemical Education, 2020
Genome editing has widespread influence in many fields, including medicine, biotechnology, and agriculture. Despite their origins in chemistry laboratories, these techniques are currently under utilized in chemistry curricula. Introducing future generations of chemists to these emerging technologies is essential in chemistry classrooms. The…
