Gee, Harold W., III; Gorton, Elizabeth S.; Cho, Sua; Fynewever, Herb – Journal of Chemical Education, 2022
We have developed and implemented a change to our General Chemistry curriculum that makes the point that "not all chemists are white men." This builds on recent textbook analyses, which showed that General Chemistry textbooks overwhelmingly and unnecessarily focus on the biographies of scientists that are white men. We demonstrate a way…

Ricca, John G.; Duersch, Bobby G.; Plaza, Tito S. Sempértegui; Haky, Jerome E. – Journal of Chemical Education, 2022
Elemental analysis is performed in a variety of ways in food and environmental sciences; thus, we have designed an activity in which students gain experience with research-level lab techniques in a real-world context through the quantification of key elements in breakfast cereals using microwave plasma optical emission spectroscopy (MP-OES). The…

Melia, Lucas F.; Barrionuevo, Santiago D.; Ibañez, Francisco J. – Journal of Chemical Education, 2022
A computational laboratory experiment is carried out to investigate the size-, geometry-, and chemistry-dependent properties of small molecules known as polycyclic aromatic hydrocarbons (PAHs) at the Facultad de Ingeniería (Universidad Nacional de La Plata, UNLP), Buenos Aires, Argentina. This computational research was adapted for upper-division…

Bazilio, Arianne A.; Kovarik, Michelle L.; Morrison, Janet F. – Journal of Chemical Education, 2022
Chemical solubility and equilibria are paramount for understanding everyday systems. Recent events have led to more interest by the general public in chemical equilibria that occur in drinking water systems. This presents a great opportunity to increase student interest and engagement in the more complicated aspects of chemical equilibria. Shiny…

Yousef, Abraham L.; Smith, Alexis G. – Journal of Chemical Education, 2022
A multistep synthesis of a novel arylidene 3­(2"H")-furanone has been designed and optimized for the second-year organic laboratory. The three-step sequence consists of a nucleophilic substitution, intramolecular cyclization, and acid-catalyzed aldol condensation, and can be carried out within two 3 h laboratory periods. The final…

Ali, Numan; Ullah, Sehat; Raees, Muhammad – Education and Information Technologies, 2022
Virtual Periodic Table (VPT) is an effective software tool to present elements in a conceivable three-dimensional (3D) mode. VPT is used to assist users in their learning before performing any hands-on activities in chemistry laboratory. Various VPTs have been developed for enhancing the learning process of chemistry education. Different types of…

Mason, Kevin; Schieffer, Steve; Rose, Tara; Matthias, Greg – Science Teacher, 2022
A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Giancaspro, Joseph; Scollan, Patrick; Rosario, Juan; Miller, Elizabeth; Braziel, Samuel; Lee, Sunghee – Biochemistry and Molecular Biology Education, 2022
In an upper-division interdisciplinary laboratory experiment, students use Raman spectroscopy to highlight how the overall structure and conformational order of lipid bilayers can be influenced by their individual phospholipid composition. Students prepare a supported lipid bilayer, as a model cell membrane, by spreading liposomes made of various…

Vo, Kimberly; Sarkar, Mahbub; White, Paul J.; Yuriev, Elizabeth – Chemistry Education Research and Practice, 2022
Problem solving is a fundamental skill that chemistry graduates should possess, yet many students have difficulties solving problems in chemistry. These difficulties may be either student- or instructor-driven. Instructor-related difficulties could stem from some teaching practices, such as expecting students to apply procedures without requiring…

Corrales, Adriana; Komperda, Regis – Journal of Chemical Education, 2022
Graduate education in chemistry typically follows an apprenticeship model, primarily aimed at preparing students for academia; however, the inclusion of teaching within this apprenticeship is not always clear as faculty, students, and other stakeholders do not agree on the need for instructional training. Despite the variability in training, a…

Jennifer G., Abigail; Jenny, Jeslin C.; Balaji, Vijayarangan Prasanna; Yadav, Rakhi – Journal of Chemical Education, 2022
Chemistry and innovations have long been coexisting in the classroom and are essential criteria for assessment. Chemistry entrepreneurship is the art of commercializing chemistry innovations and ideas to a wider audience, taking them beyond classroom and assessment. The innovative ideas when realized with social relevance show prospects for…

Jensen, Andrew; Brown, Niamh; Kosacki, Nathalie; Spacek, Sara; Bradley, Alexander; Katz, Daniel; Jimenez, Jose L.; de Gouw, Joost – Journal of Chemical Education, 2022
The COVID-19 pandemic has posed a challenge for maintaining an engaging learning environment while using remote laboratory formats. In this work, we describe a Student Choice Project (SCP) in an undergraduate instrumental analysis course that was adapted for remote learning without sacrificing research-based learning goals. We discuss the…
