Kurushkin, Mikhail; Kurushkin, Dmitry – Journal of Chemical Education, 2018
A novel educational chart that represents the acid--base behavior of 100 s-, p-, d-, and f-element oxides depending on the element's electronegativity and oxidation state was designed. An updated periodic table of said oxides was developed. A mathematical criterion based on the chart was derived which allows prediction of the behavior of…

Pollock, David W.; Truong, Giovanna T.; Bonjour, Jessica L.; Frost, John A. – Journal of Chemical Education, 2018
Solubility is frequently introduced at the high school and introductory college levels through the symbolic domain using net ionic equations and solubility product constants. Students may become proficient with spectator ion cancellation and skilled with algorithmic mathematical applications of solubility without obtaining a deeper understanding…

Rushton, Gregory T.; Criswell, Brett A.; McAllister, Nicole D.; Polizzi, Samuel J.; Moore, Lamesha A.; Pierre, Michelle S. – Journal of Chemical Education, 2014
Reaction kinetics is an axiomatic topic in chemistry that is often addressed as early as the high school course and serves as the foundation for more sophisticated conversations in college-level organic, physical, and biological chemistry courses. Despite the fundamental nature of reaction kinetics, students can struggle with transforming their…

Boyle, Timothy J.; Sears, Jeremiah M.; Hernandez-Sanchez, Bernadette A.; Casillas, Maddison R.; Nguyen, Thao H. – Journal of Chemical Education, 2017
The Chemistry Science Investigation: Dognapping Workshop was designed to (i) target and inspire fourth grade students to view themselves as "Junior Scientists" before their career decisions are solidified; (ii) enable hands-on experience in fundamental scientific concepts; (iii) increase public interaction with science, technology,…

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…

Herrington, Deborah G. – Journal of Chemical Education, 2011
A substantial number of upper-level science students and practicing physical science teachers demonstrate confusion about thermal equilibrium, heat transfer, heat capacity, and specific heat capacity. The traditional method of instruction, which involves learning the related definitions and equations, using equations to solve heat transfer…

Bridle, Chad A.; Yezierski, Ellen J. – Journal of Chemical Education, 2012
Research has shown that students in traditional college-preparatory chemistry courses become masters of mathematical equations without an understanding of the conceptual basis for the mathematical relationships. This problem is rooted not only in what curriculum is presented to students, but also in how it is experienced by the students. Ample…

Zuidema, Daniel R.; Eames, Kevin J. – Journal of Chemical Education, 2014
Student performance in a high school dual-enrollment chemistry course was compared with student performance in the corresponding traditional college course. The two courses were taught by the same instructor and evaluated using the same American Chemical Society (ACS) standardized examination. Interestingly, the high school dual-enrollment…

Cracolice, Mark S.; Busby, Brittany D. – Journal of Chemical Education, 2015
This study investigates the potential of five factors that may be predictive of success in college general chemistry courses: prior knowledge of common alternate conceptions, intelligence, scientific reasoning ability, proportional reasoning ability, and attitude toward chemistry. We found that both prior knowledge and scientific reasoning ability…

Ramm, Julia G.; Dorscheid, Gabryel L.; Passos, Camila. G.; Sirtori, Carla – Journal of Chemical Education, 2018
The general objective of this study was to analyze the development and implementation process of a waste management project (WMP) at a public school in the city of Porto Alegre in the state of Rio Grande do Sul, Brazil, that offers a course for chemistry technicians. To that end, an initial diagnostic analysis of the commonly produced waste from…

Schultz, Emeric – Journal of Chemical Education, 2010
This commentary disagrees with a recent submission (Cheung, D. "J. Chem. Educ. 2009, 86," 514-518) questioning the value of the Le Chtelier principle (LCP). Cheung points out that the LCP fails to predict the proper change in a small set of chemical equilibria. This commentary argues that the LCP has great qualitative utility in correctly…

Nicholson, Rafaelle M.; Nicholson, John W. – Journal of Chemical Education, 2012
Martha Whiteley (1866-1956) was one of the most important women chemists in the United Kingdom in the first half of the 20th century. In a male-dominated field, she was an academic on the staff of a co-educational university, Imperial College, London, where she carried out research of her own choosing, rather than assisting a male professor. She…

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…

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…

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…
