To science instructors, it may seem obvious that understanding cell theory is essential for understanding how some diseases spread and can be treated. For students, these connections are often unclear at best. For some students, this knowledge might help propel their interest in life science and keep them motivated to engage and persist even when…

Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

In the ever-evolving landscape of education, the integration of Information and Communication Technology (ICT) has emerged as a transformative force, reshaping the way we teach and learn across various disciplines. Among these disciplines, physics stands as a particularly fertile ground for harnessing the power of ICT to enhance teaching…

Gamification of learning in chemistry education is a growing field. Chemistry themed escape room activities, incorporating course learning objectives into puzzle solution, have become a popular tool allowing for students to apply course knowledge in novel settings. Escape room activities, like their public counterparts, provide subtle guidance to…

For many years, hegemonic approaches to teaching the nature of science (NOS) have focused mainly on understanding some epistemic (i.e., rational, or cognitive) aspects involved in the construction of science. So, aspects of a non-epistemic (i.e., non-rational, contextual, or extra-scientific) nature have been practically neglected in these…

Most textbooks and lecturers present Michaelis-Menten kinetics using the equation v = V[subscript max][S]/(K[subscript m] + [S]). There are advantages to presenting this relationship in a slightly different form, namely v = V[subscript max]/{1 + (K[subscript m]/[S])}. We articulate advantages for single-substrate reactions and extend the formalism…

Valence shell electron pair repulsion theory (VSEPR) as explained in most textbooks predicts that substituents bonded to a central atom in AX[subscript n]E[subscript z][superscript c] species (A = main-group central atom, X = substituent, E = lone pair on central atom, c = charge) will change their X-A-X angles to bend away from the lone pairs.…

The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

No scientific concept in the twenty-first century has garnered more attention from scholars outside the scientific community than the Anthropocene. Despite the official rejection by the geological community in March 2024 of the proposal for an Anthropocene Epoch as a formal unit of the Geological Time Scale, it is expected to remain an invaluable…

Science should provide students an accurate and contemporary education on genetic influence, particularly how it impacts trait variability and developmental norms. Stories involving familial, racial, and sexual differences routinely appear in the popular media and sales of over-the-counter genetic tests are mounting. Unfortunately, research…

Transfer of structural math knowledge to physics is difficult for students. While research suggests various improvement techniques, enhancing parallelism of algebraic structures used in physics to those studied in mathematics courses seems underrepresented. This paper proposes an alternative way of introducing wave functions as a set of parametric…

This essay opens with a question about what science teaching would look like in a world where categorical seams of human diversity were not probabilistic determinants of science learning. After revisiting Hewson and Hewson's description of an "appropriate conception of science teaching," I detail the ways in which the field of science…

In this paper I demonstrate how zines (pronounced 'zeen', a word that is a contraction of 'magazine') about space science can be theorised as a site of science education at the margins. Through exploring different zines and their potential to create counter-narratives I offer a series of objects that might reshape how we teach and learn about…

How anthropomorphic reasoning functions in scientific thinking has been a controversial topic. There is evidence it is problematic as well as evidence it can play productive roles, for scientists and for students. In science education, however, the prevailing view remains that it is an impediment. For this study, we have chosen examples of what we…

The refractive index (RI) is probably the single most important parameter in optical systems. Chromatic dispersion, on the other hand, indicates how the RI depends on the wavelength and is central in, e.g., optical communication systems. Chromatic dispersion also plays an important role when teaching optics due to the captivating natural…
