Early STEM (Science, Technology, Engineering, and Mathematics) education plays a pivotal role in shaping children's science and visual literacy skills. However, in South Africa, there are notable challenges such as delayed initiation of science education and inadequate emphasis on visual literacy. This study aims to investigate the influence of…

The traditional lecture-based scheme of teaching physics has shown to be ineffective in several aspects. It results in a lack of motivation, with low impact on students, to address more complex physical systems than the ones presented in textbooks. The electromagnetics course is a clear example at junior and senior university-level education, in…

Science and engineering students in the second semester of a calculus-based physics sequence typically study and measure the on-axis magnetic field for a multiple, circular turn coil. There are four benefits to this approach: 1) an analytical solution is easily obtained, 2) the coil is easily constructed using tightly wound, high-gauge wire where…

Physics II is an undergraduate course on basic electromagnetism that I teach for engineers, and it includes topics from optics as a natural application. Among the many challenges of conducting video lectures during the local restrictions of the SARS-CoV-2 epidemic was finding demonstration material. In this article, I describe how these…

In this work, we will describe a Peer Project Learning assignment focused on the STEM project-based learning activities where students build a custom board game with a series of constraints that guide them to learn (and later teach) about the main concepts of an electromagnetism physics course for undergraduate students.

Basic science courses, such as physics, are fundamental to precollege studies. For instance, in different engineering applications, electricity and magnetism require comprehending subjects such as electrical circuits and power electronics. However, abstract concepts such as electric or magnetic fields are often difficult to explain without visual…

In a 1993 book review, E. Pearlstein asks, "Why don't textbook authors begin their discussion of magnetism by talking about magnets? That's what students have experience with." A similar question can be asked, "Why don't professors have students measure the force between permanent magnets in introductory physics labs?" The…

In this article, we propose a simple and accessible model of a magnetic levitator fitted with a Hall sensor. This model also allows to determine the magnitude of the magnetic field within the levitator working volume. Students can also compare the experimental magnetic field values to reference values in magnetism textbooks. This Arduino-based…

This "Equity Tool" provides facts and frequently asked questions about magnet schools and their integration efforts. It is meant to be shared with various education stakeholders, including those directly involved in designing and implementing magnet school policies at the local level as well as those at state and federal levels who are…

This undergraduate laboratory experiment is designed for first-year general chemistry students with the goal of introducing the brilliant colors and magnetic properties of transition metal complexes within a bioinorganic/cell biology context. In the first laboratory period, a coordination complex formed from ferric chloride and maltol is…

A simple experiment is described to verify the current dependence of Ampère's law for a long straight current-carrying conductor. A narrow and long rectangular multi-loop design is used to increase the strength of the magnetic field in between the long sides. As expected, the magnetic field is found to be linearly proportional to the electric…

An alternative way of introducing magnetism at all levels of education is proposed. It is stressed that magnetism can be introduced through the interaction between current-carrying conductors giving the students, at the same time, the possibility to measure the magnetic permeability [mu][subscript o]. Focusing on currents instead of permanent…

The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

School choice draws upon market principles for restructuring education as schools compete for student enrollment by appealing to parents. When parents hold the power to choose where--among several options--to enroll their child for learning, they will select the school that best meets their child's academic and social-emotional needs (Cooper,…

Ultrafast laser spectroscopy is a valuable and increasingly accessible technique for studies of rapid chemical reactions. Critical to ultrafast spectroscopy is the concept of mode locking, a technique that enables a fixed phase relationship between laser modes, resulting in laser pulses with very short duration (in the fs or ps range). Despite the…
