Cruzeiro, Vinícius Wilian D.; Gao, Xiang; Kleiman, Valeria D. – Journal of Chemical Education, 2019
The ready availability of interactive platforms has produced a new generation of students able to utilize computer-based learning tools with ease and comfort. The potential to better "explore by yourself" the lecture material permits students to have an enhanced learning experience and stimulates them to tinker with equation parameters…

Minkiewicz, Piotr; Darewicz, Malgorzata; Iwaniak, Anna – Journal of Chemical Education, 2018
A simple equation to calculate the oxidation states (oxidation numbers) of individual atoms in molecules and ions may be introduced instead of rules associated with words alone. The equation includes two of three categories of bonds, classified as proposed by Goodstein: number of bonds with more electronegative atoms and number of bonds with less…

Schroeder, Lianne; Bierdz, Joshua; Wink, Donald J.; King, Maripat; Daubenmire, Patrick L.; Clark, Ginevra A. – Journal of Chemical Education, 2018
We implemented a laboratory curriculum reform to teach foundational concepts in chemistry, particularly those concepts related to healthcare, in a chemistry course for prenursing students. Here, we discuss the reform, exploring how students built upon understandings gained in lab and correlating lab learning to course outcomes. We further discuss…

Bhattacharyya, Gautam; Harris, Michael S. – Journal of Chemical Education, 2018
We report our research of seven pairs of students enrolled in the second semester of sophomore-level organic chemistry as they attempted to describe (in their own words) and draw, respectively, three electron-pushing diagrams of three-step reaction mechanisms. The tasks' objective was to accurately reproduce the diagrams based solely on the…

Graulich, Nicole; Schween, Michael – Journal of Chemical Education, 2018
Acquiring conceptual understanding seems to be one of the main challenges students face when studying organic chemistry. Traditionally, organic chemistry presents an extensive variety of chemical transformations, which often lead students to recall an organic transformation rather than apply conceptual knowledge. Strong surface level focus and…

Dood, Amber J.; Fields, Kimberly B.; Raker, Jeffrey R. – Journal of Chemical Education, 2018
The Lewis acid-base model is key to identifying and explaining the formation and breaking of bonds in a large number of reaction mechanisms taught in the sophomore-level year-long organic chemistry course. Understanding the model is, thus, essential to success in organic chemistry coursework. Concept-inventories exist to identify misunderstandings…

Miller, Tierney C.; Richardson, John N.; Kegerreis, Jeb S. – Journal of Chemical Education, 2016
This manuscript presents an exercise that utilizes mathematical software to explore Fourier transforms in the context of model quantum mechanical systems, thus providing a deeper mathematical understanding of relevant information often introduced and treated as a "black-box" in analytical chemistry courses. The exercise is given to…

Jolley, Dianne F.; Wilson, Stephen R.; Kelso, Celine; O'Brien, Glennys; Mason, Claire E. – Journal of Chemical Education, 2016
This project utilizes visual and critical thinking approaches to develop a higher-education synergistic prelab training program for a large second-year undergraduate analytical chemistry class, directing more of the cognitive learning to the prelab phase. This enabled students to engage in more analytical thinking prior to engaging in the…

Tang, Hui; Abraham, Michael R. – Journal of Chemical Education, 2016
Computer-based simulations can help students visualize chemical representations and understand chemistry concepts, but simulations at different levels of representation may vary in effectiveness on student learning. This study investigated the influence of computer activities that simulate chemical reactions at different levels of representation…

Ge, Yingbin – Journal of Chemical Education, 2016
Hands-on exercises are designed for undergraduate physical chemistry students to derive two-dimensional quantum chemistry from scratch for the H atom and H[subscript 2] molecule, both in the ground state and excited states. By reducing the mathematical complexity of the traditional quantum chemistry teaching, these exercises can be completed…

Holme, Thomas A.; Luxford, Cynthia J.; Brandriet, Alexandra – Journal of Chemical Education, 2015
Among the many possible goals that instructors have for students in general chemistry, the idea that they will better understand the conceptual underpinnings of the science is certainly important. Nonetheless, identifying with clarity what exemplifies student success at achieving this goal is hindered by the challenge of clearly articulating what…

Shultz, Ginger V.; Gere, Anne Ruggles – Journal of Chemical Education, 2015
Traditional methods for teaching the Lewis dot structure model emphasize rule-based learning and often neglect the purpose and function of the model. Thus, many students are unable to extend their understanding of molecular structures in new contexts. The assignment described here addresses this issue by asking students to read and write about the…

Miecznikowski, John R.; Guberman-Pfeffer, Matthew J.; Butrick, Elizabeth E.; Colangelo, Julie A.; Donaruma, Cristine E. – Journal of Chemical Education, 2015
In this article, the strategies and techniques used to successfully teach advanced inorganic chemistry, in the lecture and laboratory, to a legally blind student are described. At Fairfield University, these separate courses, which have a physical chemistry corequisite or a prerequisite, are taught for junior and senior chemistry and biochemistry…

Avery, Patrick; Ludoweig, Herbert; Autschbach, Jochen; Zurek, Eva – Journal of Chemical Education, 2018
The "Yet Another extended Hu¨ckel Molecular Orbital Package" (YAeHMOP) has been merged with the Avogadro open-source molecular editor and visualizer. It is now possible to perform YAeHMOP calculations directly from the Avogadro graphical user interface for materials that are periodic in one, two, or three dimensions, and to visualize…

Flood, Virginia J.; Amar, Francois G.; Nemirovsky, Ricardo; Harrer, Benedikt W.; Bruce, Mitchell R. M.; Wittmann, Michael C. – Journal of Chemical Education, 2015
When students share and explore chemistry ideas with others, they use gestures and their bodies to perform their understanding. As a publicly visible, spatio-dynamic medium of expression, gestures and the body provide productive resources for imagining the submicroscopic, three-dimensional, and dynamic phenomena of chemistry together. In this…
