The purpose of this study is to investigate the effect of MagAR, an instructional material for teaching magnetism using augmented reality and sensing technology, on students' academic achievement and learning process, and to identify students' views about augmented reality. An embedded mixed-method approach was employed in this study. The study's…

Magnetic iron oxide nanoparticles were synthesized and stabilized using ammonium cations or poly(vinyl alcohol) to produce amazing materials such as safer aqueous ferrofluids, ferrogels, ferromagnetic inks, plastics, and nanopowders illustrating how versatile materials can be produced just by simple modifications. The synthesis is fast, reliable,…

Described is an established geophysics project to construct a solar wind monitor based on a nT resolution fluxgate magnetometer. Low-cost and appropriate from school to university level it incorporates elements of astrophysics, geophysics, electronics, programming, computer networking and signal processing. The system monitors the earth's field in…

A magnetic linear accelerator (or Gauss accelerator) is a device that uses the conversion of magnetic energy into kinetic energy to launch an object with high velocity. A simple experimental implementation consists of a line of steel spheres in which the first one is a permanent magnetic sphere. If another steel ball collides with the magnetic…

The magnetic force is one of the concepts in physics that need good mathematical modeling and representation ability to understand. This article presents new learning model to help the student understand this concept with various representation, knowing by doing, and accommodate their mathematics modeling ability. GIMuR model has five phases,…

Race and class segregation have long governed patterns of residential sorting in the American metropolis. However, as urban neighborhoods across the country experience an influx of white and middle-class residents, they could alleviate the stark economic and racial segregation that is ubiquitous to urban neighborhoods and school systems. This…

As science becomes increasingly computationally intensive, the need for computational thinking (CT) and computer science (CS) practices in K-12 science education is becoming paramount. Incorporation of CT/CS practices in K-12 education can be seen in national standards and a variety of allied initiatives. One way to build capacity around an…

The posterior superior temporal sulcus is a potential therapeutic target of brain stimulation for autism spectrum disorder. We conducted a 4-week randomized, single-blind parallel sham-controlled trial, followed by additional 4-week open-label intervention to evaluate the feasibility and efficacy regarding intermittent theta burst stimulation over…

Hispanics comprise the fastest-growing ethnicity in the United States. One in five college students is Hispanic. While Hispanics are gaining access to higher education, their college completion rate is dismal, compared to Whites and other ethnicities. Hispanics face unique academic and social challenges in college. This phenomenological study was…

Agentic engagement refers to students' proactive and constructive contribution into the flow of classroom instruction and activities. Given its potential as a student-initiated pathway to promoting motivation and learning, the goal of this study was to describe agentic engagement from the perspectives of racially diverse students in urban high…

Magnetism and its various applications are essential for our daily life and for many technological developments. The term "magnetism" is almost always used as a synonym for ferromagnetism. However, the magnetic properties of the elements of the periodic table indicate that the vast majority of elements are not ferromagnetic, but rather,…

The spatial dependence of magnetic fields in simple configurations is a common topic in introductory electromagnetism lessons, both in high school and in university courses. In typical experiments, magnetic fields and distances are obtained taking point-by-point values using a Hall sensor and a ruler, respectively. Here, we show how to take…

The new 9-1 GCSE courses in Physics include reference to both permanent and induced magnets. In this article I briefly examine the origin of ferromagnetism, diamagnetism and paramagnetism and suggest a number of helpful classroom demonstrations.

An experiment with an electric transformer based on single coils shows how electromagnetic induction changes when the magnetic coupling between coils is adjusted. This transformer has two secondary outputs which are taken differentially. This is the basis for a widely used position transducer known as LVDT.

This article proposes and explores the kinds of computational thinking, creative practices, design activities, and inclusive learning opportunities provided to diverse high school youth when designing integrated systems through simultaneously physically and digitally responsive wearable games and systems. Previous work in this area, conducted by…
