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…

Ogilvie, J. F.; Monagan, M. B. – Journal of Chemical Education, 2007

The teaching of mathematics courses to chemistry students that is strongly based on symbolic computation and allows an instructor to explore a topic or principle is reviewed. The mathematical software available, nominally for symbolic computation associated with numerical and graphical capabilities are highly developed and provides an invaluable…

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…

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,…

Contreras-Ortega, C.; Bustamante, N.; Guevara, J. L.; Portillo, C.; Kesternich, V. – Journal of Chemical Education, 2007

A general mathematical treatment for chemical systems is described that might help students to better understand the real scope of the mathematical equations. The extent to which an equation acceptably describes a chemical system is determined from the limiting values of practical chemical variables and the concordance value defined by given…

Desjardins, Steven G. – Journal of Chemical Education, 2008

In this paper we describe an interdisciplinary course on dynamics that is appropriate for nonscience majors. This course introduces ideas about mathematical modeling using examples based on pendulums, chemical kinetics, and population dynamics. The unique emphasis for a nonmajors course is on chemical reactions as dynamical systems that do more…

Bendall, Sophie; Birdsall-Wilson, Max; Jenkins, Rhodri; Chew, Y. M. John; Chuck, Christopher J. – Journal of Chemical Education, 2015

Chemical engineering is rarely encountered before higher-level education in the U.S. or in Europe, leaving prospective students unaware of what an applied chemistry or chemical engineering degree entails. In this lab experiment, we report the implementation of a three-day course to showcase chemical engineering principles for 16-17 year olds…

DePierro, Ed; Garafalo, Fred; Toomey, Rick – Journal of Chemical Education, 2008

This paper summarizes difficulties that chemistry students at all levels commonly exhibit when translating, manipulating, and interpreting mathematical expressions that contain logarithms, and offers approaches that the authors have found useful to help students overcome such difficulties. The online supplement provides problem sets created by the…

Eberhart, James G. – Journal of Chemical Education, 2010

Most thermodynamic properties are either extensive (e.g., volume, energy, entropy, amount, etc.) or intensive (e.g., temperature, pressure, chemical potential, mole fraction, etc.). By the same token most of the mathematical relationships in thermodynamics can be written in extensive or intensive form. The basic laws of thermodynamics are usually…

Garland, Eva R.; Garland, Harry T. – Journal of Chemical Education, 2006

A summer course was developed with the goal of preparing girls to succeed in secondary school chemistry. Group work and mathematical, logical, and laboratory skills were stressed in the course, with minimal emphasis on memorization. Students who took the summer course ranked statistically higher during their first semester of high school chemistry…

Burkholder, Phillip R.; Purser, Gordon H.; Cole, Renee S. – Journal of Chemical Education, 2008

Intermolecular forces play an important role in many aspects of chemistry ranging from inorganic to biological chemistry. These forces dictate molecular conformation, species aggregation (including self-assembly), trends in solubility and boiling points, adsorption characteristics, viscosity, phase changes, surface tension, capillary action, vapor…

Walczak, Mary M.; Walczak, Daniel E. – Journal of Chemical Education, 2009

The importance of educating people to live in our increasingly science- and technology-rich world is well established. Many institutions require students to take one or more courses in science. Some nonscience majors are intrigued by this opportunity, while others are less inclined to take science classes. This project used a mixed-methods…

Poce-Fatou, J. A.; Bethencourt-Nunez, M.; Moreno, C.; Pinto-Ganfornina, J. J.; Moreno-Dorado, F. J. – Journal of Chemical Education, 2008

This article presents a lab experience to study detergency from a physicochemical point of view intended for undergraduate students. By means of a simple experimental device, we analyze the influence of the surfactant concentration in both distilled water and tap water. Our method is based on the measurement of diffuse reflectances of polyester…

Arnquist, Isaac J.; Beussman, Douglas J. – Journal of Chemical Education, 2007

Biological mass spectrometry is an important analytical technique in drug discovery, proteomics, and research at the biology-chemistry interface. Currently, few hands-on opportunities exist for undergraduate students to learn about this technique. With the 2002 Nobel Prize being awarded, in part, for the development of biological mass…

Swinehart, D. F. – Journal of Chemical Education, 1985

A previous article stated that only the matrix method was powerful enough to balance a particular chemical equation. Shows how this equation can be balanced without using the matrix method. The approach taken involves writing partial mathematical reactions and redox half-reactions, and combining them to yield the final balanced reaction. (JN)
