Alyssa M. Suzuki; Skylar M.-D. Blattner; Emily Kulaga; Sara McGhee; Jordyn Rosete; Serena M. Salas; Tim Humphry; Amy L. Fuller – Journal of Chemical Education, 2024
A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

Moore, Thomas – Chemical Engineering Education, 2022
It is natural to interpret entropy as a measure of energy dispersion. However, the classical, phenomenological introduction to the topic, which relies on detailed analysis of Carnot engines, obscures this interpretation. Here, we propose a modification of the classical approach, which allows the basic properties of entropy to be proven without…

César Zúñiga-Loyola; Maria-Soledad Ureta-Zanartu; Federico Tasca – Journal of Chemical Education, 2024
Energy conversion devices such as fuel cells, metal-air batteries, and electrolyzers have been envisaged as possible solutions for cutting down the continuous accumulation of greenhouse gases resulting from the combustion of fossil fuel. The bottleneck reaction for these devices is the oxygen reduction reaction (ORR) occurring at the cathode. The…

Clare G. -C. Franovic; Nicholas R. Williams; Keenan Noyes; Michael W. Klymkowsky; Melanie M. Cooper – CBE - Life Sciences Education, 2023
Concerns regarding students' difficulties with the concept of energy date back to the 1970s. They become particularly apparent for systems involving adenosine triphosphate (ATP), which plays a central role in maintaining the nonequilibrium state of biological systems and in driving energetically unfavorable processes. One of the most…

Suárez, Álvaro; Martí, Arturo C.; Zuza, Kristina; Guisasola, Jenaro – Physical Review Physics Education Research, 2023
Textbooks play a fundamental role in teaching and learning in school science classrooms. In this paper, we investigate the presentation of the nature of the electromagnetic field in a dozen of the world's most popular introductory university physics textbooks. We analyze, from an epistemologically based teaching approach, the didactic treatment of…

Thomas S. Kuntzleman – Journal of Chemical Education, 2023
An activity is described that uses simple materials and an easy-to-perform protocol to estimate the Curie temperature of nickel, which is the temperature at which nickel loses its ferromagnetism. To do so, an object made of nickel metal is heated with a lighter until it loses its ferromagnetism. The metal is allowed to drop into a beaker that…

Christoph Hoyer; Raimund Girwidz – Physical Review Physics Education Research, 2024
Vector fields are a highly abstract physical concept that is often taught using visualizations. Although vector representations are particularly suitable for visualizing quantitative data, they are often confusing, especially when describing real fields such as magnetic and electric fields, as the vector arrows can overlap. The present study…

Dazhen Tong; Huihui Wu; Hongmei Ren; Zhirong Wang; Sudong Pan; Lei Bao – Physical Review Physics Education Research, 2025
Achieving knowledge integration for deep learning requires students to construct well-connected knowledge structures by understanding and applying the central ideas of a concept. However, research on student learning in work and mechanical energy reveals persistent challenges in grasping fundamental concepts, particularly in connecting the…

Wu, Guobin; Wu, Amy Yimin – Physics Education, 2021
This paper starts with an introduction to the concept of momentum current. It is followed by a discussion of its strength and density with the aid of several analogies made between momentum current and electric current. Based on the novel concepts of thermal charge and its quantity (entropy), the analogies are extended to entropy current. The…

Derek Gladwin; Naoko Ellis – Environmental Education Research, 2023
Energy is fundamental to our existence. And yet, energy remains difficult to understand and discuss, particularly the impacts or limitations of certain energy systems and how energy functions in sociocultural contexts. Bridging theory and practice, energy literacy expands what we know about energy and how we may think about it in the world around…

Preston, Christine M.; Hubber, Peter J.; Xu, Lihua – Research in Science Education, 2022
Primary school topics involving abstract concepts are challenging to teach. Electric circuits can be simply constructed but complex to explain. New approaches in teaching students for understanding are needed to advance practice in primary science. This paper combines the strengths of multimodality research perspectives with variation theory to…

Mary Jane Brundage; David E. Meltzer; Chandralekha Singh – Physical Review Physics Education Research, 2024
We use the Survey of Thermodynamic Processes and First and Second Laws-Long, a research-based survey instrument with 78 items at the level of introductory physics, to investigate introductory and advanced students' difficulties with internal energy, work, and heat transfer. We present analysis of data from 12 different introductory and advanced…

Miquel Solà; F. Matthias Bickelhaupt – Journal of Chemical Education, 2022
Simple mathematical models can serve to reveal the essence of experimental phenomena and scientific concepts. The particle in a box (PIB), for example, is widely used in undergraduate programs to teach the quantum mechanical principles behind the UV--vis spectra of conjugated polyenes and polyynes. In this work, the particle on a ring (POR) and…

Saba, Janan; Langbeheim, Elon; Hel-Or, Hagit; Levy, Sharona T. – Journal of Research in Science Teaching, 2023
Electricity, especially the flow of current, is a challenging topic for students of all ages. This study conceptualizes students' explanation of electric current as a cluster of knowledge elements. These clusters, in turn, represent students' mental models of electric circuits. Thus, this study aims to identify and characterize students' mental…
