Srnec, Matthew N.; Upadhyay, Shiv; Madura, Jeffrey D. – Journal of Chemical Education, 2016

In this technology report, a tool is provided for teaching reciprocal space to undergraduates in physical chemistry and materials science courses. Reciprocal space plays a vital role in understanding a material's electronic structure and physical properties. Here, we provide an example based on previous work in the "Journal of Chemical…

Seethaler, Sherry; Czworkowski, John; Wynn, Lynda – Journal of Chemical Education, 2018

Change over time is a crosscutting theme in the sciences that is pivotal to reaction kinetics, an anchoring concept in undergraduate chemistry, and students' struggles with rates of change are well-documented. Informed by the education scholarship in chemistry, physics, and mathematics, a research team with members from complementary disciplinary…

Koopman, Lodewijk; Brouwer, Natasa; Heck, Andre; Buma, Wybren Jan – Journal of Chemical Education, 2008

Proper mathematical skills are important for every science course and mathematics-intensive chemistry courses rely on a sound mathematical pre-knowledge. In the first-year quantum chemistry course at this university, it was noticed that many students lack basic mathematical knowledge. To tackle the mathematics problem, a remedial mathematics…

Bauer, Christina A.; Hamada, Terianne Y.; Kim, Hyesoo; Johnson, Mathew R.; Voegtle, Matthew J.; Emrick, Matthew S. – Journal of Chemical Education, 2018

Quantum dots (QDs) are useful for demonstrating the particle-in-a-box (PIB) model utilized in quantum chemistry, and can readily be applied to a discussion of both thermodynamics and kinetics in an undergraduate laboratory setting. Modifications of existing synthetic procedures were used to create QDs of different sizes and compositions (CdS…

Bain, Kinsey; Rodriguez, Jon-Marc G.; Towns, Marcy H. – Journal of Chemical Education, 2018

Zero-order systems provide an interesting opportunity for students to think about the underlying mechanism behind the physical phenomena being modeled. The work reported here is part of a larger study that seeks to characterize how students integrate chemistry and mathematics in the context of chemical kinetics. Thirty-six general chemistry…

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…

Thomas, Ashleigh L. P. – Journal of Chemical Education, 2017

This paper presents gradual implementation of active learning approaches in an organic chemistry classroom based on student feedback and strategies for getting students on-board with this new approach. Active learning techniques discussed include videos, online quizzes, reading assignments, and classroom activities. Preliminary findings indicate a…

Pollock, David W.; Truong, Giovanna T.; Bonjour, Jessica L.; Frost, John A. – Journal of Chemical Education, 2018

Solubility is frequently introduced at the high school and introductory college levels through the symbolic domain using net ionic equations and solubility product constants. Students may become proficient with spectator ion cancellation and skilled with algorithmic mathematical applications of solubility without obtaining a deeper understanding…

Perez-Benito, Joaquin F. – Journal of Chemical Education, 2017

The elementary reaction sequence A ? I ? Products is the simplest mechanism for which the steady-state and quasi-equilibrium kinetic approximations can be applied. The exact integrated solutions for this chemical system allow inferring the conditions that must fulfill the rate constants for the different approximations to hold. A graphical…

Srnec, Matthew N.; Upadhyay, Shiv; Madura, Jeffry D. – Journal of Chemical Education, 2017

In undergraduate physical chemistry, Schrödinger's equation is solved for a variety of cases. In doing so, the energies and wave functions of the system can be interpreted to provide connections with the physical system being studied. Solving this equation by hand for a one-dimensional system is a manageable task, but it becomes time-consuming…

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…

Manae, Meghna A.; Hazra, Anirban – Journal of Chemical Education, 2016

In a course on chemical applications of symmetry and group theory, students learn to use several useful tools (like character tables, projection operators, and correlation tables), but in the process of learning the mathematical details, they often miss the conceptual big picture about "why" and "how" symmetry leads to the…

Schaller, Chris P.; Graham, Kate J.; McIntee, Edward J.; Peterson, Alicia A.; Strollo, Christen M.; Jakubowski, Henry V.; Fazal, M. A.; Johnson, Brian J.; Jones, T. Nicholas; Raigoza, Annette M. – Journal of Chemical Education, 2018

A novel laboratory curriculum is presented, developed around some common tasks of a laboratory researcher in chemistry: purification, synthesis, and measurement. The capstone of the sequence is an integrated laboratory, leading to a more independent research experience. Students who have completed this laboratory curriculum appear to perform…

Rittenhouse, Robert C. – Journal of Chemical Education, 2015

The "atoms first" philosophy, adopted by a growing number of General Chemistry textbook authors, places greater emphasis on atomic structure as a key to a deeper understanding of the field of chemistry. A pivotal concept needed to understand the behavior of atoms is the restriction of an atom's energy to specific allowed values. However,…

Hladky, Paul W. – Journal of Chemical Education, 2011

College students encounter a variety of first-order phenomena in their mathematics and science courses. Introductory chemistry textbooks that discuss first-order processes, usually in conjunction with chemical kinetics or radioactive decay, stop at single, discrete dose events. Although single-dose situations are important, multiple-dose events,…
