Neuman, Annette W.; Harmon, Brenda B. – Journal of Chemical Education, 2019
An integrated lab-lecture project, known as the mini research project, was developed for a medicinal chemistry course for nonscience majors. In the lecture component of this project, students choose a plant essential oil with documented biological activity and prepare a literature review describing the importance, history, and current use of the…

Grosso, Carla; Liber, Marta; Brigas, Amadeu F.; Pinho e Melo, Teresa M. V. D.; Lemos, Américo – Journal of Chemical Education, 2019
Regioselectivity in hetero Diels-Alder reactions can be observed in a simple reaction between a nonsymmetrical heterodiene and an unsymmetrical heterodienophile. A 9 h and easy to implement laboratory experiment is described, in which students can observe the regioselectivity of inverse "electron-demand" hetero Diels-Alder reactions of…

Blackburn, Richard A. R.; Villa-Marcos, Barbara; Williams, Dylan P. – Journal of Chemical Education, 2019
A series of laboratory themed simulations developed by Learning Science Ltd. were integrated into a first year laboratory module at the University of Leicester. These simulations allow students to attempt the experiments they will do in the laboratory in a risk-free way that provides the opportunity to make mistakes and learn how to correct them…

Seery, Michael K.; Jones, Ariana B.; Kew, Will; Mein, Thomas – Journal of Chemical Education, 2019
Experimental design is a desirable outcome of laboratory education. Incorporating inquiry into the laboratory curriculum is attractive, but there are acknowledged concerns from practical, theoretical, and epistemological perspectives, and these are accentuated in upper-division courses. In this work, we draw on the extensive literature relating to…

Agcali, Rahime Yagmur; Atik, Bahar; Bilgen, Ecenaz; Karli, Berfu; Danisman, Mehmet Fatih – Journal of Chemical Education, 2019
Understanding the concepts of quantum mechanics has always been a challenge for undergraduate students. This is especially so because many of the introductory (analytically solvable) systems and problems discussed in textbooks are seemingly abstract. Using approximate experimental demonstrations of such systems and problems have been shown to be…

Calcabrini, Mariano; Onna, Diego – Journal of Chemical Education, 2019
The study of gels and their properties is a compelling topic both technologically and scientifically, and should therefore be emphasized in chemistry and material science syllabuses. In the present laboratory experiment, we propose two experiences, aimed at introducing gelation and gel transport properties using silica gels made from sodium…

Kwan, Ann H.; Mobli, Mehdi; Schirra, Horst J.; Wilson, Jennifer C.; Jones, Oliver A. H. – Journal of Chemical Education, 2019
Magnetic resonance is a powerful technology that has had a major impact across the physical, life, and medical sciences, from chemistry to medical imaging, with ever-expanding applications in new areas as diverse as mining and food science. It is, however, also a difficult subject to teach, as the theory is complex and requires some familiarity…

Boys, Alexander J.; Walsh, Mark C. – Journal of Chemical Education, 2019
Elementary and middle school science curricula typically focus on generating an interest in science and engineering through the use of hands-on activities that demonstrate specific concepts. Laboratory activities designed in this manner often circumvent some of the main challenges that engineers and scientists face, namely balancing advantages and…

Esselman, Brian J.; Block, Stephen B. – Journal of Chemical Education, 2019
The VSEPR model has well-established limitations in its ability to represent accurate molecular and electronic geometries of simple molecules, which can create a significant need for students to relearn structure and bonding concepts in organic chemistry. We present an alternate method for describing molecular geometries and electronic structures…

Dip, Irene; Gethers, Christina; Rice, Tonya; Straub, Thomas S. – Journal of Chemical Education, 2019
4-"tert"-Butylcyclohexanol is rapidly converted to 4-"tert"-butylcyclohexanone with swimming pool bleach in a homogeneous reaction at room temperature. This process introduces students to a heterocyclic compound not normally discussed in the introductory course and has significant advantages over standard procedures using…

Lindsay, Andrew J. – Journal of Chemical Education, 2019
A semester-long, project-based series of laboratory exercises is described that provides practical experience of the upstream and downstream processes involved in monoclonal antibody production. This 6 week project is aimed at final year undergraduate students undertaking primary degrees in biotechnology, biochemistry, or related disciplines.…

Ryan, Stephanie A. C.; Stieff, Mike – Journal of Chemical Education, 2019
Extant research on the efficacy of drawing for assessing learning in chemistry suggests it may provide richer information on the quality of students' mental models. Here, we examine the relative utility of formative assessments that involve drawing modalities as well as verbal and symbolic modalities. We analyzed the drawings, written…

Niece, Brian K. – Journal of Chemical Education, 2019
Models were prepared by 3D printing that can be used to demonstrate the operations required for the study of molecular symmetry. The models were designed to emphasize the order and locations of rotation axes and to clearly illustrate the more abstract reflection and improper rotation axes. The models were well-received by students in a course on…

Abell, Timothy N.; Bretz, Stacey Lowery – Journal of Chemical Education, 2019
The Enthalpy and Entropy in Dissolution and Precipitation Inventory (E2DPI) has been developed to measure student understanding of the dissolution of ionic solutes, aqueous precipitation reactions, and the enthalpy and entropy changes that accompany these processes. The E[subscript 2]DPI was designed using a mixed-methods protocol, such that the…

Sterner, Elizabeth S. – Journal of Chemical Education, 2019
Polymer chemistry lab experiments present a unique opportunity to allow students to experience the consequences of reaction mechanisms on the properties of the resulting product. In this organic chemistry experiment, students prepared a polyamide by three different reaction mechanisms that represent step-growth and chain-growth methods of…
