Seethaler, Sherry; Czworkowski, John; Wynn, Lynda – Journal of Chemical Education, 2018
Change over time is a crosscutting theme in the sciences that is pivotal to reaction kinetics, an anchoring concept in undergraduate chemistry, and students' struggles with rates of change are well-documented. Informed by the education scholarship in chemistry, physics, and mathematics, a research team with members from complementary disciplinary…

Dori, Yehudit Judy; Dangur, Vered; Avargil, Shirly; Peskin, Uri – Journal of Chemical Education, 2014
Chemistry students in Israel have two options for studying chemistry: basic or honors (advanced placement). For instruction in high school honors chemistry courses, we developed a module focusing on abstract topics in quantum mechanics: Chemistry--From the Nanoscale to Microelectronics. The module adopts a visual-conceptual approach, which…

Bauer, Christina A.; Hamada, Terianne Y.; Kim, Hyesoo; Johnson, Mathew R.; Voegtle, Matthew J.; Emrick, Matthew S. – Journal of Chemical Education, 2018
Quantum dots (QDs) are useful for demonstrating the particle-in-a-box (PIB) model utilized in quantum chemistry, and can readily be applied to a discussion of both thermodynamics and kinetics in an undergraduate laboratory setting. Modifications of existing synthetic procedures were used to create QDs of different sizes and compositions (CdS…

Bain, Kinsey; Rodriguez, Jon-Marc G.; Towns, Marcy H. – Journal of Chemical Education, 2018
Zero-order systems provide an interesting opportunity for students to think about the underlying mechanism behind the physical phenomena being modeled. The work reported here is part of a larger study that seeks to characterize how students integrate chemistry and mathematics in the context of chemical kinetics. Thirty-six general chemistry…

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…

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…

Mabrouk, Patricia Ann; Schelble, Susan M. – Journal of Chemical Education, 2018
An interactive poster exhibited at two poster sessions at the Fall 2016 American Chemical Society (ACS) National Meeting was used as a vehicle to learn about ACS members' concerns and needs related to research ethics and to identify opportunities for engagement of the Society by the Committee on Ethics (ETHX) and others in terms of ethics…

Chitiyo, George; Potter, Darek W.; Rezsnyak, Chad E. – Journal of Chemical Education, 2018
The "Atoms-First" approach has received considerable attention in the chemical education community over the past few years as an alternative to the standard reaction-based two-semester General Chemistry curriculum. The Atoms-First model emphasizes the electronic structure of the atom as a means to explain and rationalize chemical…

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,…

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…

Hibbard, Lisa; Sung, Shannon; Wells, Breche´ – Journal of Chemical Education, 2016
Flipped learning has come to the forefront in education. It maximizes learning by moving content delivery online, where learning can be self-paced, allowing for class time to focus on student-centered active learning. This five-year cross-sectional study assessed student performance in a college general chemistry for majors sequence taught by a…

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…
