Adaptive expertise concerns the ability to respond effectively to novel and unexpected situations. This expertise is important for improving students' cognitive engagement, understanding and participation in meaningful learning. This paper presents findings on primary teachers' adaptive expertise in interdisciplinary mathematics and science using…

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…

Biochemistry lab classes help students connect theory to real-world applications and develop practical, collaborative, and higher-order thinking skills. However, many students are unprepared, spending class time on protocols and equipment instead of higher-order learning. To improve preparation, digital gamified modules were created to replace…

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…

With policies that strongly emphasize reading, teachers need interdisciplinary strategies that not only represent professional scientists' practices but also support students' engagement and learning in both science and reading. Opportunities abound for teachers to help students recognize the fluid connections between disciplines such as science,…

The directional feature of Earth's geomagnetic field has been contributing to the technological development and prosperity of humankind since the invention of the magnetic compass navigation centuries ago. Today, for instance, magnetoresistance sensors are commonly used in nanosatellites and unmanned aerial vehicles for high accuracy geomagnetic…

In this work, we venture to show how careful use of a program for quantum chemical calculations (such as VASP) may enrich teaching in solid-state chemistry and how principles of thermodynamics contribute to a validation of phase diagrams and reaction pathways using the quasiternary system Li[subscript 2]O-Al[subscript 2]O[subscript…

Chemical thinking is a powerful tool for making sense of the material world and acting on it. But developing competence in chemical thinking may be challenging for students as it varies in several dimensions. This contribution seeks to guide and help chemistry educators in the design of learning experiences that support the development of…

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…

Classical magnetic resonance is a phenomenon that occurs when the magnetic moment is exposed to combined strong, constant external, and weak alternating magnetic fields. When the frequency of the alternate magnetic field matches the resonant frequency of the oscillator, the amplitude of its oscillation increases drastically. Since the magnetic…

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 describes low-cost well plates that can be used as alternative kits for microscale experiments. Although ordinary well plates are useful and convenient for microscale experiments, they are not cheap. We have developed well plates composed of plastic bottle caps with approximately 3cm diameter and cardboard containers. Plastic bottle…

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…

Brewing science is an interdisciplinary course taught at many universities in both lecture- and lab-based modalities. The laboratory component of this class typically focuses on the brewing process from malted barley to beer. However, this ignores the malting process--an essential step in making beer, although one typically performed by maltsters…

Nuclear magnetic resonance (NMR) spectroscopy is commonly introduced to students in the classroom, but its hands-on use in undergraduate laboratories is far less common. The significant costs to purchase and maintain a traditional high-field NMR spectrometer means that many institutions cannot offer this service to their students. Benchtop NMR…
