A novel teaching approach is aimed at elucidating the concept of bond enthalpy for general chemistry students. Through the integration of a hands-on candy pulling activity, students in a large lecture class were provided a tangible experience to explore bond strengths using rope candy and a luggage scale. Feedback from students indicated a clear…

Photochemical reactions are initiated by the absorption of light, triggering the chemical reactions and resulting in the formation of products. These reactions are generally performed using a freely available renewable source of energy-solar energy. Solar simulators mimic both the ultraviolet and visible regions of sunlight and hence can serve as…

We examine students' challenges in determining the number of distinct many-particle stationary states for a system of noninteracting identical particles, focusing on how these insights guided the design, validation, and evaluation of a quantum interactive learning tutorial (QuILT) to aid students' understanding. Specifically, we focus on systems…

Previous studies have documented the promising results from student-constructed representations, including stop-motion animation (SMA), in supporting mechanistic reasoning (MR), which is considered an essential thinking skill in science education. Our current study presents theoretically and empirically how student-constructed SMA contributes to…

While many university health science programs include physics courses to raise knowledge and understanding of physical science concepts, they are still far from addressing the needs of that science health profession. This study aimed to investigate the effect of an introductory physics course on first-year physiotherapy and rehabilitation (PR)…

Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

The essence of university courses lies in their scientific rigor, while the enjoyment of learning serves as a motivation. In this regard, we have developed a comprehensive experiment project by incorporating dithienylethene-based photochromic units into sensitizers for renewable energy, specifically dye-sensitized solar cells, through organic…

Science centres are informal learning spaces embedded with artefacts embodying mediational affordances. This exploratory and small-scale mixed methods study juxtaposes eye-tracking technologies and qualitative interviews to examine how visitors to a gallery navigated this space and interacted with different artefacts. A total of 15 visitors to the…

This study examined the impact of a practice-based approach to in-service science teacher education, using small-group discussions about photovoltaic (PV) science to support teachers' instruction on sustainable energy transitions in response to climate change risks. Ultimately, we aimed to promote teachers' PV science comprehension as well as…

This research aimed to determine the effectiveness of applying instructive simulation experiments (SE) to the development of deeper conceptual understanding, retention of static electricity contents, and engagement of 4th-grade students. The correlation between student achievements and engagement was examined. 76 4th graders (10-11 years) were…

One of the critical goals of teaching chemistry is to enable learners to gain conceptual understanding. Traditional instruction has often been associated with rote memorisation, resulting in learners failing to explain observed chemical phenomena, make predictions based on acquired concepts, advance convincing arguments, and engage in meaningful…

Literature on student ideas about circuits largely focuses on misunderstandings and difficulties, with seminal papers framing student thinking as stable, difficult to change, and connected to incorrect ontological categorizations of current as a thing rather than a process. In this paper, we analyzed 417 student responses to a conceptual question…

We report the design of a low-cost electrochemical workstation and open-source graphical user interface capable of performing a variety of electrochemical methods in an undergraduate teaching laboratory. The instrument--based on the popular Arduino microcontroller board--can be constructed from common components for $40 USD. The modular design of…

The concepts of electronegativity and classical electronegativity scales are briefly described. Electronegativity scales have practical quantitative applications, and this work suggests activities which can assist students select the scales for use in chemistry applications. It provided examples of the use of an appropriate electronegativity…

Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…
