Bain, Kinsey; Towns, Marcy H. – Journal of Chemical Education, 2018
The concept of energy is of central significance, as it is a core disciplinary idea in chemistry and a cross-cutting concept in the sciences. This study sought to investigate student understanding of energetics and associated thermodynamic functions in chemical reactions and processes across a sample of introductory-level undergraduate chemistry…

Li, Zhao; Corti, David S. – Journal of Chemical Education, 2018
The application of the Reaction Monte Carlo (RxMC) algorithm to standard textbook problems in chemical reaction equilibria is discussed. The RxMC method is a molecular simulation algorithm for studying the equilibrium properties of reactive systems, and therefore provides the opportunity to develop computer-based "experiments" for the…

Gautreau, Cynthia; Brye, Michelle Vanderveldt; Mitra, Sinjini; Winstead, Lisa – Journal of Latinos and Education, 2022
There is an urgent need for more Latinx students to pursue careers in STEM related fields as this has historically been an unserved population in schools. This mixed methods study examined the impact of a summer STEM pipeline program focused on hands-on chemistry concepts for 28 Latinx students in the 5th grade. Findings include statistically…

Fernández-Terán, Ricardo; Sucre-Rosales, Estefanía; Echevarría, Lorenzo; Hernández, Florencio E. – Journal of Chemical Education, 2020
Herein we present an engaging description of the existent analogy between social distancing during the COVID-19 pandemic and the collision cross-section of particles as defined in the collisional model for a chemical reaction. In addition, the link between collision cross-sections and kinetic rate constants is thoroughly established, bridging…

Peffley, Nicole – Science Teacher, 2018
This inquiry-based lesson gets students moving to simulate chemical reactions in a way that allows them to visualize, understand, and retain information about chemical reactions in the stratosphere. Students then look at scientific data and conduct research to understand trends in the data and the impact of chlorofluorocarbons (CFCs). These…

Kapici, Hasan Özgür – International Journal of Research in Education and Science, 2023
Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…

Altarawneh, Mohammednoor; Dlugogorski, Bogdan – Journal of Chemical Education, 2018
Due to the wide and the ever-increasing strategic applications of quantum chemistry in chemical industries, it is important to introduce chemical engineering students to illustrative case studies that deploy molecular modeling in the design of reactors and derivation of thermochemical functions. Herein, we demonstrate how quantum chemical…

Caushi, Klaudja; Sevian, Hannah; Talanquer, Vicente – Journal of Chemical Education, 2021
Chemical scientists and engineers are interested in controlling chemical processes to attain specific goals, from synthesizing a desired substance to hindering a particular transformation. Nevertheless, students typically have few opportunities to develop the understandings and practices that are required to effectively engage in chemical control.…

Cinti, Stefano – School Science Review, 2021
Every day we deal with chemistry in various forms, but sometimes we don't see that. An example is biosensors that help us to evaluate health conditions, monitor environmental pollution and ensure food freshness. The most well known (and most widely sold) is the biosensor for blood glucose measurement, used every day by people with diabetes.…

Brown, Patrick – Science and Children, 2023
Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Kodani, Satoki; Koga, Nobuyoshi – Journal of Chemical Education, 2021
A newly developed laboratory learning program for high school chemistry courses is discussed, in which students discover the chemical mechanism governing exothermic phenomena during the reaction between a heating agent, namely, calcium oxide (CaO)--aluminum (Al) mixture, and water. Based on prior knowledge of simple heating agents such as CaO, the…

Novak, Igor – Journal of Chemical Education, 2020
Theoretical yield and extent of reaction (degree of completion) are important concepts in stoichiometry and in chemical kinetics. We provide expressions describing theoretical yield (Y) and maximum extent of reaction (fractional yield, f[subscript max]) for five examples of commonly encountered reversible chemical reactions: A [equilibrium sign]…

Gupta, Anju; Hill, Nicole; Valenzuela, Patricia; Johnson, Eric – Journal of STEM Education: Innovations and Research, 2017
Recruiting students in STEM majors to fill the gap in STEM workforce is a continued challenge, which can be addressed by introducing scientific principles through hand-on activities to the students at an early stage. This paper presents the design, implementation and assessment of a chemistry-related workshop for sixth grade students that were…
