Raff, Lionel M.; Cannon, William R. – Journal of Chemical Education, 2019

For 26 years, it has been assumed by some that the thermodynamics of open-system biochemical reactions must be executed by performing Legendre transformations on the terms involving the species whose concentrations are being held fixed. In contrast, standard nontransformed thermodynamics applies to chemical processes. However, it has recently been…

Tra, Yolande V.; Evans, Irene M. – CBE - Life Sciences Education, 2010

"BIO2010" put forth the goal of improving the mathematical educational background of biology students. The analysis and interpretation of microarray high-dimensional data can be very challenging and is best done by a statistician and a biologist working and teaching in a collaborative manner. We set up such a collaboration and designed a course on…

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…

Baumgartner, Erin; Biga, Lindsay; Bledsoe, Karen; Dawson, James; Grammer, Julie; Howard, Ava; Snyder, Jeffrey – American Biology Teacher, 2015

Quantitative literacy is essential to biological literacy (and is one of the core concepts in "Vision and Change in Undergraduate Biology Education: A Call to Action"; AAAS 2009). Building quantitative literacy is a challenging endeavor for biology instructors. Integrating mathematical skills into biological investigations can help build…

Keller, Charles; Hendrix, Tonya; Xu, Na; Porter-Morgan, Holly; Brashears, Allie – Journal of College Science Teaching, 2018

A variety of factors contribute to attrition in science, technology, engineering, and mathematics (STEM) education at the community college level including underpreparedness, lack of confidence, and broader socioeconomic issues. This work describes our efforts to improve student learning and overall success in a community college General Biology I…

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…

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…

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…

Robic, Srebrenka – CBE - Life Sciences Education, 2010

To fully understand the roles proteins play in cellular processes, students need to grasp complex ideas about protein structure, folding, and stability. Our current understanding of these topics is based on mathematical models and experimental data. However, protein structure, folding, and stability are often introduced as descriptive, qualitative…

Flohic, Hélène M. L. G. – Journal of Astronomy & Earth Sciences Education, 2017

A common challenge among university professors is how to best design undergraduate courses to successfully enhance students' attitudes. To compare which curriculum was more efficient at fostering a positive attitude towards science in general, I studied the impact of two different general education science courses on the attitudes of college…

Langbeheim, Elon; Rez, Peter – Journal of Geoscience Education, 2017

This paper describes the basic tenets of a sustainable energy course for university science majors. First, it outlines the three core components of the course: (1) The scientific evidence for the connection between climate change and energy usage; (2) An analysis of the capacity and environmental impact of various renewable and traditional energy…

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…

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…
