The aim of the present research was to explore the use of concept maps as an assessment tool. The research question posed was: can concept maps be used to quantitatively assess the learning of a physics topic in an engineering course? This paper describes a new approach to quantifying concept maps. The research was preceded by a pilot project that…

The success of films such as "Avengers: Endgame," "Black Panther," and "Captain Marvel" has established the superhero genre in modern popular culture. Many students will have seen these films, or at the very least they are familiar with a number of the superhero characters. In the physics classroom, content based on…

So many fundamental physics problems involve rigid body rotation that mastery of the subject is essential to many science and engineering undergraduate degrees. Rigid body rotation is typically taught in introductory mechanics courses and while students are generally comfortable with the corresponding kinematic equations, torques and moments of…

The objective of this study was to analyze visual representations of redox reactions and related content in four Brazilian secondary school chemistry textbooks. The study aimed to identify which representations were used and to evaluate how these representations were linked to one another and to the main text. Data were analyzed regarding…

Properly made solutions are critical to the scientific method. However, in various laboratories and collaborative environments, we have noticed a lack of proper technique for making solutions. Instead of measuring the moles of solute then filling up to the needed volume with solvent, we observed many individuals would measure the moles of solute…

In contrast to the determinist and non-discrete structure of classical physical concepts, the probabilistic and discrete/quantised structure of quantum physics embeds certain difficulties in deeper understanding and teaching activities. In this study, in order to understand and to teach the concept of quantization more effectively, a clear analogy…

The aim of this study is to explore how tertiary science students' use of metaphors in their popular science article writing may influence their understanding of subject matter. For this purpose, six popular articles written by students in physics or geology were analysed by means of a close textual analysis and a metaphor analysis. In addition,…

Instructive, inexpensive, and environmentally friendly laboratory syntheses of two highly luminescent copper(I) complexes CuI(PPh[subcript 3])[subscript 2](py[superscript R]) (py[superscript R] = pyridine, 4-cyanopyridine) are described for second-year/upper-division undergraduate inorganic chemistry students. Both complexes exhibit bright…

In this paper, I engage with arguments put forth by Anna Günther-Hanssen in her article "A swing and a child: How scientific phenomena can come to matter for preschool children's emergent science identities." Günther-Hanssen argues that new materialism can help us see how scientific phenomena can create affordances in becoming scientific…

Set in the context of modeling-based learning (MBL), this research investigated the potential of epistemic frames as a theoretical and analytical framework for understanding teaching and learning practices used in classroom communities of practice. Epistemic frames are conceptualized as an orienting lens for a classroom community of practice that…

Nanoscale phenomena are under increasingly intense investigation both in academia and industry. The unique physical and chemical properties stemming from their high surface area and confined space lead to properties that are distinct from atomic and bulk materials. Students need experience in nanoscience to enter this growing field of nanoscience…

"Complex systems" is a general-purpose reasoning scheme, used in a wide range of disciplines to make sense of systems with many similar entities. In this paper, we examine the generality of this approach in learning chemistry. Students' reasoning in chemistry in terms of emergent complex systems is explored for two curricula: a normative…

This article provides two additional mnemonics that can serve to help undergraduate students recall how to apply the rules of writing net ionic equations. These mnemonics were incorporated into dozens of lecture and laboratory class content, which includes hundreds of undergraduate (health professions and physical science major) students. As a…

Medical students have difficulty understanding the mechanisms underlying hyperkalemia-mediated local control of blood flow. Such control mechanisms are crucial in the brain, kidney, and skeletal muscle vasculature. We aimed to identify medical students' misconceptions via assessment of students' in-class knowledge and, subsequently, improve future…

Electromagnetic radiation can be classified into two major types depending on its ability to detach electrons from atoms: ionising and non-ionising. The aforementioned categorization is significant due to the effects of ionising radiation on human tissue (e.g. carcinogenesis). However, many students around the globe cannot distinguish these two…
