Electricity and magnetism are fundamentally interconnected, as represented by the symmetry in Maxwell's equations. Much of the research on Gauss's and Ampere's laws has focused on their application in calculating electric or magnetic fields. However, there remains a significant gap in the literature in exploring these laws in a broader…

Contribution: This article proposes a comprehensive graduate course on magnetic design that addresses existing gaps in current power electronics (PEs) education, provides theoretical foundations and hands-on skills, and matches syllabi coverage with current societal needs for electronic energy conversion. Background: A growing worldwide interest…

We describe the implementation of a specially designed teaching innovation, embedded in the context of energy, for the promotion of specific aspects of the nature of science (NOS). We present empirical results from the implementation of the teaching and learning materials in three intact sixth-grade classes that involved a total of 64 students. We…

Reactive oxygen species such as singlet oxygen have been a major focus of research in medicine. The effect of singlet oxygen on sterols within biological membranes is becoming increasingly more important. Ergosterol, a vitamin D precursor, is one such sterol. The benzoylation of ergosterol and subsequent reaction with singlet oxygen to form an…

Background: Problem-based learning (PBL) is a teaching approach working in cooperation with self-learning and involving research to solve real problems. The first law of thermodynamics states that energy can neither be created nor destroyed, but that energy is conserved. Students had difficulty learning or misconceptions about this law. This study…

Research has shown that technology-enhanced visualizations can improve inquiry learning in science when they are designed to support knowledge integration. Visualizations play an especially important role in supporting science learning at elementary and middle school levels because they can make unseen and complex processes visible. We identify 4…
