Darvesh, Katherine V. – Journal of Chemical Education, 2013
The equilibrium between phases is a key concept from the introductory physical chemistry curriculum. Phase diagrams display which phase is the most stable at a given temperature and pressure. If more than one phase has the lowest Gibbs energy, then those phases are in equilibrium under those conditions. An activity designed to demonstrate the…

Hijnen, Hens – Journal of Chemical Education, 2009
A theoretical description of the influence of electroosmosis on the effective mobility of simple ions in capillary zone electrophoresis is presented. The mathematical equations derived from the space-charge model contain the pK[subscript a] value and the density of the weak acid surface groups as parameters characterizing the capillary. It is…

Brom, Joseph M. – Journal of Chemical Education, 2017
The concept of wave-particle duality in quantum theory is difficult to grasp because it attributes particle-like properties to classical waves and wave-like properties to classical particles. There seems to be an inconsistency involved with the notion that particle-like or wave-like attributes depend on how you look at an entity. The concept comes…

Feierabend, Timo; Eilks, Ingo – Journal of Chemical Education, 2011
This paper discusses a chemistry lesson plan based on the use of ethanol as an alternative and renewable energy source. The lessons were developed by participatory action research and follow a socio-critical and problem-oriented approach to chemistry teaching. This approach specifically focuses on the handling of scientific and technological…

Scalfani, Vincent F.; Turner, C. Heath; Rupar, Paul A.; Jenkins, Alexander H.; Bara, Jason E. – Journal of Chemical Education, 2015
The emergence of 3D printing has dramatically advanced the availability of tangible molecular and extended solid models. Interestingly, there are few nanostructure models available both commercially and through other do-it-yourself approaches such as 3D printing. This is unfortunate given the importance of nanotechnology in science today. In this…

Struyf, Jef – Journal of Chemical Education, 2011
The boiling point of a monofunctional organic compound is expressed as the sum of two parts: a contribution to the boiling point due to the R group and a contribution due to the functional group. The boiling point in absolute temperature of the corresponding RH hydrocarbon is chosen for the contribution to the boiling point of the R group and is a…

Raker, Jeffrey R.; Reisner, Barbara A.; Smith, Sheila R.; Stewart, Joanne L.; Crane, Johanna L.; Pesterfield, Les; Sobel, Sabrina G. – Journal of Chemical Education, 2015
A national survey of inorganic chemists explored the self-reported topics covered in in-depth inorganic chemistry courses at the postsecondary level; an in-depth course is defined by the American Chemical Society's Committee on Professional Training as a course that integrates and covers topics that were introduced in introductory and foundation…

Junker, Matthew – Journal of Chemical Education, 2010
A classroom exercise is described to introduce enzyme kinetics in an undergraduate biochemistry or chemistry course. The exercise is a simulation in which a student acts as an enzyme that "catalyzes" the unscrewing of a nut from a bolt. With other students assisting, the student enzyme carries out reactions with bolt-nut substrates under different…

Casselman, Brock L.; Atwood, Charles H. – Journal of Chemical Education, 2017
In a first-semester general chemistry course, metacognitive training was implemented as part of an online homework system. Students completed weekly quizzes and multiple practice tests to regularly assess their abilities on the chemistry principles. Before taking these assessments, students predicted their score, receiving feedback after…

Lasker, Grace A.; Mellor, Karolina E.; Mullins, Melissa L.; Nesmith, Suzanne M.; Simcox, Nancy J. – Journal of Chemical Education, 2017
Despite advances in active learning pedagogy and other methods designed to increase student engagement in the chemistry classroom, retention and engagement issues still persist, particularly with respect to women and minorities underrepresented in STEM (science, technology, engineering, and mathematics) programs. Relevancy also remains elusive in…

Schroeder, Jacob; Murphy, Kristen L.; Holme, Thomas A. – Journal of Chemical Education, 2012
General chemistry tests from the Examinations Institute of the Division of Chemical Education of the American Chemical Society have been analyzed to identify factors that may influence how individual test items perform. In this paper, issues of item order (position within a set of items that comprise a test) and answer order (position of correct…

Glover, Sarah R.; Sewry, Joyce D.; Bromley, Candice L.; Davies-Coleman, Michael T.; Hlengwa, Amanda – Journal of Chemical Education, 2013
Education institutions globally are increasingly expected to explore avenues for the implementation of service-learning into their curricula. A second-year undergraduate organic chemistry laboratory experiment, in which the undergraduate students make azo dyes, can provide a vehicle for a service-learning module in which university undergraduate…

Glasser, Leslie – Journal of Chemical Education, 2014
We introduce various methods which are used to depict three-dimensional objects on two-dimensional surfaces. Many of these are artistic and not conducive to exact interpretation. Instead, the scientific and engineering practices and mathematics of orthographic projection are introduced, and illustrated in an accompanying interactive Excel…

Reed, Jessica J.; Villafan~e, Sachel M.; Raker, Jeffrey R.; Holme, Thomas A.; Murphy, Kristen L. – Journal of Chemical Education, 2017
General chemistry courses are often the foundation for the study of other science disciplines and upper-level chemistry concepts. Students who take introductory chemistry courses are more often from health and science-related fields than chemistry. As such, the content taught and assessed in general chemistry courses is envisioned as building…

Fakayode, Sayo O.; Yakubu, Mamudu; Adeyeye, Olasumbo M.; Pollard, David A.; Mohammed, Abdul K. – Journal of Chemical Education, 2014
Diversification of our country's science talent pool is critically needed and can only be achieved by stimulating interest in science, technology, engineering, and mathematics (STEM) among students from a wide variety of cultural backgrounds. However, motivating, increasing the number, improving retention rates, and graduation rates of…
