Marle, Peter D.; Decker, Lisa; Taylor, Victoria; Fitzpatrick, Kathleen; Khaliqi, David; Owens, Janel E.; Henry, Renee M. – Journal of Chemical Education, 2014
This paper discusses a K-12/university collaboration in which students participated in a four-day scenario-based summer STEM (science, technology, engineering, and mathematics) camp aimed at making difficult scientific concepts salient. This scenario, Jumpstart STEM-CSI: Chocolate Science Investigation (JSCSI), used open- and guided-inquiry…

Blanck, Harvey F. – Journal of Chemical Education, 2005
A device designed to emulate diffusion and thermal conductivity using flowing water is reviewed. Water flowing through a series of cells connected by a small tube in each partition in this plastic model is capable of emulating diffusion and thermal conductivity that occurs in variety of systems described by several mathematical equations.

Malel, Esteban; Shalev, Deborah E. – Journal of Chemical Education, 2013
Iron corrosion is a complex process that occurs when iron is exposed to oxygen and humidity and is exacerbated by the presence of chloride ions. The deterioration of iron structures or other components can be costly to society and is usually evaluated by following the properties of the corroding material. Here, the iron ions released into solution…

Cook, Elzbieta; Kennedy, Eugene; McGuire, Saundra Y. – Journal of Chemical Education, 2013
College students often find general chemistry to be a very challenging rite of passage on their way to degrees in various science, technology, and mathematics disciplines. As teachers, we make efforts to simultaneously patch gaps in students' prior knowledge and instill valuable learning strategies and sound study habits. In this paper, we…

Martínez, Leandro – Journal of Chemical Education, 2014
The protein folding (Levinthal's) paradox states that it would not be possible in a physically meaningful time to a protein to reach the native (functional) conformation by a random search of the enormously large number of possible structures. This paradox has been solved: it was shown that small biases toward the native conformation result…

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…

Clark, Rose A.; Stock, Anne E.; Zovinka, Edward P. – Journal of Chemical Education, 2012
Training future chemists to be aware of the environmental impact of their work is of fundamental importance to global society. To convince chemists to embrace sustainability, the integration of green chemistry across the entire chemistry curriculum is a necessary step. This experiment expands the reach of green chemistry techniques into the…

Rowland, Sherwood F. – Journal of Chemical Education, 2004
The ACS (American Chemical Society) plays a major role in the facilitation of the teaching of established knowledge, the extension of this knowledge and public service, which become even more important because they are embedded in society highly dependent in its daily activities on the fruits of science and technology. The president of the ACS and…

Lewis, Scott E. – Journal of Chemical Education, 2011
This study describes an evaluation of the Peer-Led Team Learning (PLTL) reform model in first-semester general chemistry. PLTL was implemented in place of one-third of the available lecture time, maintaining the same amount of structured class time under the reform. The evaluation demonstrates that classes implementing the PLTL reform at the…

Garip, Mehmet; Erdil, Erzat; Bilsel, Ayhan – Journal of Chemical Education, 2006
A survey on the attitudes of engineering faculty to chemistry, physics, and mathematics was conducted with the aim of clarifying the attitudes of engineering faculty to chemistry courses in relation to engineering education or curricula and assessing their expectations. The results confirm that on the whole chemistry is perceived as having a…

Bretz, Stacey Lowery; Fay, Michael; Bruck, Laura B.; Towns, Marcy H. – Journal of Chemical Education, 2013
Forty chemistry faculty from American Chemical Society-approved departments were interviewed to determine their goals for undergraduate chemistry laboratory. Faculty were stratified by type of institution, departmental success with regard to National Science Foundation funding for laboratory reform, and level of laboratory course. Interview…

Laursen, Anders B.; Varela, Ana Sofia; Dionigi, Fabio; Fanchiu, Hank; Miller, Chandler; Trinhammer, Ole L.; Rossmeisl, Jan; Dahl, Soren – Journal of Chemical Education, 2012
The electrochemical hydrogen evolution reaction (HER) is growing in significance as society begins to rely more on renewable energy sources such as wind and solar power. Thus, research on designing new, inexpensive, and abundant HER catalysts is important. Here, we describe how a simple experiment combined with results from density functional…

Towns, Marcy H. – Journal of Chemical Education, 2010
Across the United States many chemistry departments are engaged in developing assessment plans. New guidelines from the American Chemical Society (ACS) Committee on Professional Training request a department's latest self-assessment and a plan for acting on the recommendations. This manuscript describes assessment practices at institutions ranging…

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…
