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…

Blanco, Francesco; La Rocca, Paola; Petta, Catia; Riggi, Francesco – European Journal of Physics, 2009
An educational model simulation of the sound produced by lightning in the sky has been employed to demonstrate realistic signatures of thunder and its connection to the particular structure of the lightning channel. Algorithms used in the past have been revisited and implemented, making use of current computer techniques. The basic properties of…

Mitchell, Joseph D.; Petrov, Nikola P. – European Journal of Physics, 2009
We apply several physical ideas to determine the steady temperature distribution in a medium moving with uniform velocity between two infinite parallel plates. We compute it in the coordinate frame moving with the medium by integration over the "past" to account for the influence of an infinite set of instantaneous point sources of heat in past…

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…

Nemirovsky, Ricardo, Ed.; Rosebery, Ann S., Ed.; Solomon, Jesse, Ed.; Warren, Beth, Ed. – Lawrence Erlbaum Associates (Bks), 2005
This book re-examines the dichotomy between the everyday and the disciplinary in mathematics and science education, and explores alternatives to this opposition from points of view grounded in the close examination of complex classroom events. It makes the case that students' everyday experience and knowledge in their entire manifold forms matter…

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…

Gelfand, I. M., Ed. – Quantum, 1991
Describes the Mathematics Correspondence School that was organized in late 1960s and still directed by the author, to serve about 1,000 Russian secondary students in small cities and remote villages. Discusses this project's extension to other disciplines, and the introduction of English versions of the school's textbooks via this regular journal…

Finkel, LeRoy – 1991
This book is designed for use in an introductory, college level course on educational technology, and no prior experience with computers or computing is assumed. The first of a series on technology in the classroom, the text provides a foundation for exploring more specific topics in greater depth. The book is divided into three…

Meek, Simon J.; Pitman, Catherine L.; Miller, Alexander J. M. – Journal of Chemical Education, 2016
An introductory guide to deducing the mechanism of chemical reactions is presented. Following a typical workflow for probing reaction mechanism, the guide introduces a wide range of kinetic and mechanistic tools. In addition to serving as a broad introduction to mechanistic analysis for students and researchers, the guide has also been used by…

Andrews, David L.; Bradshaw, David S. – European Journal of Physics, 2009
Nonlinear optics is generally first presented as an extension of conventional optics. Typically the subject is introduced with reference to a classical oscillatory electric polarization, accommodating correction terms that become significant at high intensities. The material parameters that quantify the extent of the nonlinear response are cast as…

Shaw, Ken – Journal of Chemical Education, 2008
This story is a chemical mystery with an emphasis on qualitative analysis, descriptive chemistry, and forensics. It is as well yet another article in the continuing series, first presented by Thomas Waddell and Thomas R. Rybolt, which presents a scientific problem in mystery format in the context of the popular and beloved characters of Sherlock…

Taber, Keith S.; Bricheno, Pat – International Journal of Science Education, 2009
The present paper discusses the conceptual demands of an apparently straightforward task set to secondary-level students--completing chemical word equations with a single omitted term. Chemical equations are of considerable importance in chemistry, and school students are expected to learn to be able to write and interpret them. However, it is…

Galleano, Monica; Boveris, Alberto; Puntarulo, Susana – Journal of Chemical Education, 2008
This article describes a simple and inexpensive laboratory exercise developed to understand the effect of pressure on phase equilibrium as described by the Clausius-Clapeyron equation. The only piece of equipment required is a pressure cooker adapted with a pressure gauge and a thermometer in the lid, allowing the measurement of the pressure and…
