Pepino, Ron A.; Mabile, Risley W. – Physics Teacher, 2023
It has long been suspected by general relativists that physicists who do not specialize in general relativity (GR) believe that special relativity (SR) is incapable of modeling dynamics within accelerated reference frames. Consequently, many physicists may conclude that certain phenomena, such as time dilation due to acceleration, can only be…

Felipe Xavier de Melo; César Augusto Melo-Silva; Veronica Moreira Amado – Advances in Physiology Education, 2024
The distribution of pulmonary blood flow is uneven and can be described as a three-zone model, the West zones: zone 1 occurs whenever alveolar pressure exceeds arterial pressure; zone 2 when the arterial pressure is greater than alveolar but the alveolar pressure exceeds the venous pressure; and finally zone 3 when both arterial and venous…

Jack Thomas-Colwell; Ramya S. Pathuri; Aaron H. Shoemaker; Michael G. Hill; Bryan M. Hunter – Journal of Chemical Education, 2025
The study of coordination complexes in general and inorganic chemistry courses is facilitated by theoretical frameworks such as crystal field theory (CFT) and ligand field theory (LFT). The angular overlap model (AOM) is alternative approach that quantifies metal-ligand interactions based on the geometric configuration of a given complex. In this…

John R. Jungck – Bioscene: Journal of College Biology Teaching, 2023
Why should our life science colleagues adopt, adapt, and implement fractal thinking into their research and teaching paradigms? While numerous articles and books have been written about the utility, power, and insight that can be gained by using fractal analysis of data and developing fractal models, other than just appreciating the beauty of…

Lincoln, Don – Physics Teacher, 2022
The standard model of particle physics is the most successful theory describing the behavior of matter and energy in the subatomic realm. However, success doesn't mean it is perfect, and a recent measurement of the mass of a particle called the W boson is puzzling, as it disagrees with theoretical predictions and earlier precise measurements. If…

Cumber, Peter – International Journal of Mathematical Education in Science and Technology, 2023
The dynamics of a simple pendulum are often presented to undergraduate engineering students in introductory courses in dynamics. It is usually the first dynamic system considered by students that is modelled by a differential equation. This paper presents the standard material given to students. It is fair to say that students are accepting this…

Oh, Woo-Jin; Park, Hogul; Paik, Seoung-Hey – Physics Teacher, 2022
Science is the activity of studying the natural world in various ways to construct theories and models to explain phenomena. Windschitl et al. reported that model-based inquiry includes the connection between observable aspects of the target phenomenon and conjectured underlying causal processes. In addition, they insisted that learners are…

Wenyuan Yang; Sihang Chen; Cheng Liu – American Biology Teacher, 2024
Modeling is a core practice in science and is a meaningful way to learn the subject. This article introduces a modeling-based approach that highlights the idea that modeling is an iterative process and integrates the fundamental parts of scientists' work and key suggestions for teaching through modeling. The lesson "The Structure and Function…

Linda Hämmerle; Daniela Hlavka; Michael Kiehn; Peter Pany; Peter Lampert – American Biology Teacher, 2024
Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

Karaismailoglu, Fatma; Yildirim, Mehtap – Biochemistry and Molecular Biology Education, 2023
This article presents the integration of Tinkercad, a free online modeling program that allows students to model molecular genetic concepts, into the distance learning process. The students had the opportunity to learn molecular genetics in a fun and more efficient way in spite of the limitations of the COVID-19 lockdown, and, in this respect, it…

Edmonds, Juliet – Primary Science, 2022
A drama model can be helpful to support children's understanding of some of the more abstract parts of the science curriculum. The drama models can usefully enhance children's understanding of scientific processes and concepts. They can help to link the practical activities with the conceptual understanding. The use of more than one way of…

Winkelmann, Jan – Science & Education, 2023
Idealizations are omnipresent in science. However, to date, science education research has paid surprisingly little attention to the use of idealizations in fostering students' model competence and understanding of the nature of science (NOS). The starting point for the theoretical reflection in this paper is that insufficient consideration of…

Jiro Kondo; Shota Nakamura – Journal of Chemical Education, 2023
The use of molecular models in chemistry and biochemistry classes is very effective in helping students understand covalent bonds and the chemical structure of molecules. However, conventional molecular models cannot represent intermolecular interactions such as hydrogen bonds and electrostatic interactions. Herein, we describe 3D printed…

Kubsch, Marcus; Hamerski, Patti C. – Physics Teacher, 2022
Energy is a disciplinary core idea and a cross-cutting concept in the K-12 Framework for Science Education and the Next Generation Science Standards (NGSS). As numerous authors point out, the energy model in these standards emphasizes the connections between energy and systems. Using energy ideas to interpret or make sense of phenomena means…

Panorkou, Nicole; Germia, Erell – For the Learning of Mathematics, 2023
In this article, we address a call by Thompson and Carlson to directly contribute to defining the variation of students' reasoning about varying quantities. We show that students as young as in sixth grade can engage in complex forms of reasoning about multiple quantities in contexts that involve exploring science phenomena using interactive…
