The study investigated the impact of guided inquiry-based laboratory experiments enriched instructional (GIBLEI) approach on conceptual understanding of tenth grade students in biology. The study included two purposively chosen schools and used a quasi-experimental design with non-equivalent groups. A class was randomly assigned as the…

Teaching redox reactions requires careful investigation as learners often display a range of misconceptions, particularly in connecting the chemistry levels of representation: macroscopic, sub-microscopic, and symbolic. This study explores teachers' teaching strategies, opportunities, and challenges when developing conceptual understanding of…

This mixed methods study explored how the making of animated models affected year 11 students' understanding of the effect of temperature on the equilibrium of an exothermic or endothermic reaction. The students' perspectives and the role of the activity in facilitating a metacognitive process were also examined. Teacher perspectives were also…

With increasing emphasis on post-secondary readiness in core subjects such as English, Mathematics, and Science, educators in Career and Technical Education face significant challenges, including declining enrollment and the integration of updated curricula. This study aimed to address these issues within agricultural education by piloting a new…

Digital technology has increasingly transformed the landscape of science education, positioning gamification as a powerful pedagogical tool to enhance learner engagement and comprehension. This study investigated the application of digital gamification using Kahoot! to enhance comprehension of biology subject content among secondary school…

Using a feminist-new materialist lens, this paper attends to child-digital interactions in fostering Indigenous literacies, by focusing on the "Quantum Sandbox" exhibit in the Digital Immersion Lab at a Canadian children's science museum. Analytically, this paper explores how a digital exhibit ("Quantum Sandbox") creates a…

In this paper, we present an empirical study carried out in a country where STEM education does not have a tradition, and the content and didactics of mathematics are typically studied separately from the content and didactics of biology. In that context, we focus on analogies in the conceptual structure of mathematics and biology, and study how…

This paper describes a way to simulate and visualise 3D representations of the resultant electric field vector propagation for plane, circular and elliptically polarised waves. These polarisation states are obtained by the superposition of two coherent linearly polarised waves oscillating in two mutually perpendicular directions. The required data…

The Earth is in the midst of a recent acceleration in the rate of species extinction and the unravelling of ecological communities. The authors think with the emerging field of Extinction Studies to explore educational approaches to ecological endangerment and extinction. Using a notion of visiting as 'curious practice', we story encounters…

Concept inventories are commonly used tools in physics education research (PER) for evaluating teaching methods. Student responses to concept inventories have been studied using classical test theoretical methods such as factor analysis and network methods such as module analysis. The results of these studies have been used to evaluate the…

The toppling motion of falling chimney stacks has been the subject of a number of studies which address the interesting phenomenon that brick chimneys usually break well before they hit the ground. Modern concrete chimneys, and wind generator towers, however, are strong enough to topple without breaking and many videos of their destruction are…

Creating pleasant musical sounds by vibrating the strings of musical instruments such as guitars and violins is the result of the type of instrument played as well as the mastery of the player. This article explains the physics of vibrating strings caused either by a bow drawn over them or by being plucked, and provides a simple analysis to…

This article highlights some of the challenges in explaining simple substituent effects on keto-enol equilibria, particularly to an undergraduate audience. Quantum-chemical calculations were performed to identify the role of intramolecular hydrogen bonding, inductive effects due to electron-withdrawing groups, and cross-conjugation on the…

Many high school and first-year university courses include discussion of the magnetic effect of currents. Frequently discussed textbook examples include long, straight wires, circular current loops, and solenoids, partly because these examples are tractable mathematically. The solenoid naturally leads to discussion on magnetic materials since it…

Basis vectors e[subscript alpha] play a useful role in special and general relativity. In particular they allow an expansion of the vectorial spacetime interval dl along infinitesimal curvilinear coordinate differences dl = e[subscript alpha]d[Xi][superscript alpha]: (thus the definition e[subscript alpha] = dl/d[Xi][superscript alpha]). In this…
