Resonance is an important, and rather dramatic, phenomenon in physics. The mechanical case of a mass-spring oscillator is generally the first example that students encounter in introductory courses. In electromagnetism, the resonance in driven RLC circuits is presented in analogy with mechanics, since the mathematical equations describing them are…

India has borrowed a colonial legacy of English language education from its British colonizers. Post-Independence, education policies pertaining to the language of instruction in school education have unequivocally been supporting multilingual education. However, the policy mandates have not been translated in the same way in classroom practices.…

In socially shared regulation of learning, adaptation is a key process for overcoming collaborative learning challenges. Monitoring the learning process allows learners to recognize the situations that require a need to change, revise, or optimize the current learning process. This can be done through adapting their strategies, task perception,…

How teachers' changes in their science teaching practices unfold over time remains unclear. We need greater understanding of the processes at work in professional development (PD) and how to sustain those processes that are effective over time. Effective PD processes are seen as those that recognize teacher change is…

This study was performed to figure out the relationship between undergraduate students' 21st-century skills (21CSs), physics academic achievements, attitudes towards physics, and perceptions of physics teaching and learning. The study was carried out with 329 undergraduate students who had taken physics courses from Architecture-Engineering,…

There is broad agreement in the literature (e.g. Furtak et al., 2012; Harlen and Qualter, 2018) that the purpose of primary science is for children to develop: (1) scientific skills; (2) knowledge and understanding of some scientific concepts; (3) positive attitudes to science; an understanding of the nature of science; and (4) an appreciation of…

In the ever-changing world based on the needs, curiosity and entrepreneurial drive of the humankind, interest in socio-scientific issues has been increasing every day with the discussion and different approaches in society. It could be suggested that the increase in this interest has been due to both the contribution and damages of these issues to…

The image of free-falling bar has been recorded to study the effect of the motion on its observed length. This moving bar image is analysed using the Tracker software to determine its length and the end bar's position. An elongated appearance of the bar has been observed with movement. This effect relies on the speed and the exposure time during…

This paper examines the representation of women in Irish Leaving Certificate Physics textbooks. Findings show that women are significantly underrepresented, both in terms of scientific characters (historic and current) described within the textbooks, and also in terms of more general non-scientific characters within the books. Furthermore,…

In this article we present a simple experimental set-up to determine the band gap of germanium and silicon using the "ExpEYES-17" kit. The experiment is based on the temperature dependence of the reverse current through germanium and silicon diodes at different temperatures. The experimental values are found to agree well with accepted…

This article presents a simple, fast, and equally accurate technique for measuring the area of a circle and of an ellipse without using geometric formulas. This therefore, together with the known radius of the circle and the semi-major and semi-minor axes of the ellipse, allows for the calculation of [pi]. The experiment is easy, thrilling, and…

A course centered around transition-metal catalysis in modern drug discovery was designed to illustrate the central role of organic chemistry in driving small-molecule drug development. The course highlighted both fundamental and applied concepts, first with a focus on the drug discovery process, followed by foundational principles in catalysis…

Research has shown that the use of practical examples in undergraduate education promotes the retention of historically underrepresented students in STEM majors and lowers achievement gaps within courses. Since many students of color and women aspire toward careers in healthcare and the pharmaceutical industry, efforts to incorporate medicinal…

We describe here a 4 hour experimental session based on reaction monitoring of the degradation of an organic pollutant via a Fenton-like reaction. An aqueous solution of p-nitrophenol is treated with hydrogen peroxide and magnetite, and the progress of the reaction is monitored by UV-vis spectrophotometry and/or gas chromatography using an…

Assumptions about the feasibility of teaching chemistry laboratories online have been challenged by the ongoing COVID-19 pandemic. We argue that, despite the fact that pandemic social distancing restrictions will be eventually eliminated, the development of quality digital laboratory resources must continue to receive attention from the chemistry…
