The purpose of this study is to examine how students may hold coexisting and competing conceptual ideas and how students' uses of such ideas may evolve during the process of conceptual change by combining two complementary methods including model analysis and the conceptual framework model of knowledge integration. Conceptual change is fundamental…

Predictive processing (PP) has been repeatedly presented as a unificatory account of perception, action, and cognition. In this paper, we argue that this is premature: As a unifying theory, PP fails to deliver general, simple, homogeneous, and systematic explanations. By examining its current trajectory of development, we conclude that PP remains…

Argumentation constitutes an important element in nature of science education. However, its virtues and scope can be overstated. Here, we survey in detail the place of argumentation in science education. Our benchmark is the range of epistemic processes relevant to citizens and consumers as they assess the reliability of scientific claims in…

Teaching materials frequently answer objections to evolution by demarcating science from religion. Because definitions of science shaped by demarcation tend to magnify its empirical features, they weaken students' understanding of science's theoretical dimension. Demarcation fails to answer creationism for the opposite reason; by insisting that…

Existing research identifying common student ideas about forces focuses on students' misunderstandings, misconceptions, and difficulties. In this paper, we characterize student thinking in terms of resources, framing student thinking as continuous with formal physics. Based on our analysis of 2048 written responses to conceptual questions, we…

The classic brachistrochrone problem is standard material in intermediate mechanics. Many variations exist including some accessible to introductory students. While a quantitative solution isn't feasible in introductory classes, qualitative discussions can be very beneficial since kinematics, Newton's laws, energy conservation, and motion along…

While the three laws of conservation of energy, momentum, and angular momentum are all mentioned in introductory textbooks, there are few experiments through which students can investigate the conservation of angular momentum. Most experiments consist of collisions between rotating disks, in which one disk is dropped on another, or in which the…

Fermat's principle states that a light ray refracted across different media will traverse the fastest path as the physics for Snell's law. A geometric proof of Fermat's principle will be demonstrated as an intuitive approach to learn high school geometry and physical optics. It will be proved explicitly by showing that all alternative paths need…

The purpose of this study is to consider Superman's acts against impulse-momentum and conservation of momentum principles. Superheroes as fantasy fiction characters attract the attention of not only children and teenagers but also adults. Superheroes can be useful in explaining a phenomenon, as well as overcoming conceptual difficulties that may…

Student understanding of the laws that describe the flow of a fluid is often hampered by a defective knowledge of basic classical mechanics (kinematics, statics, dynamics, and conservation laws) and by wrong common-sense ideas about quantities related to fluids, such as velocity and pressure. A pedagogical discussion about the Venturi effect,…

Electrochemical and spectroelectrochemical techniques are very important for characterizing energy materials. In the search for new sources of renewable energy, water splitting for hydrogen production and CO[subscript 2] reduction is attracting significant attention. These applications require efficient and durable catalysts and a detailed…

Although residues and resource shortages are major problems of modern living, these topics are not usually properly covered in university curricula. To tackle this situation, we have guided undergraduate students through the design of a group of active learning activities, to demonstrate the science behind separation and recycling: trash…

The formulation of the periodic system by the Russian Mendeleev was followed by the surprising discovery of gallium by the Frenchman de Boisbaudran. The Englishman Ramsay's explanation of an 'impurity' in air led to recognition of a new period. A young fellow countryman, Moseley, justified the expected existence of 92 elements. A German couple,…

Elementary students learn best when they make observations about perplexing natural phenomena, ask questions about what they observed, and pursue answers to their own questions through engagement in science practice. However, facilitating such learning experiences can be challenging for novice instructors. In this unit, pre-service elementary…

This study aimed to investigate how argument-driven inquiry (ADI) activities impact pre-service teachers' views of the nature of scientific inquiry (NOSI), with a specific focus on climate change. To this end, an ADI approach was used to teach climate change, where the aspects of NOSI were explicitly taught. A sample of 24 pre-service teachers…
