In this work, we explore how undergraduate students use classical field theory when describing physical phenomena in the context of introductory electromagnetism. We have extracted five key characteristics of the electric and magnetic field from a historical analysis of the topic. These characteristics informed the creation of a questionnaire…

In this article, we describe how to develop an inductive metal detector that can be integrated to any Android or iOS smartphone with a standard audio port at low cost. The results indicate the metal detector can be used in the physics teaching laboratory as a practical application of principles of electromagnetism. It allows one to differentiate…

As the introduction of natural sciences in early childhood education differs from natural sciences for adults, planning appropriate activities for preschool is a delicate task with various dimensions and parameters. Teaching natural sciences in kindergarten can be a complex procedure which combines exploring and comprehending children's…

This study demonstrated that the constant average speed of a dynamic car could be measured and calculated using the smartphone magnetometer. The apparatus setup was built using a dynamic car, a linear track up to 1.50 m, a bunch of magnets, and a smartphone magnetometer application. The smartphone magnetometer application, 'Physics Toolbox Suite',…

Characterized by thematic instructional programs and voluntary enrollment, magnet schools are often the result of a neighborhood schooling effort to increase racial integration and academic achievement. With the continued expansion of magnet schools, it is critical that stakeholders have a comprehensive research synthesis of their potential…

When the idea of having a Kids' Inquiry Conference (KIC) in the author's school was discussed, she was motivated to participate because of her belief in children as capable protagonists of their learning. These Reggio-inspired beliefs made her confident that her preschool class would be successful participants in this challenging scientific…

Harmful plastic debris found on beaches and in the oceans are not limited to drinking straws or bags. There are several synthetic organic polymers that can be used to make different kinds of plastic materials and have resulted in billions of tons of waste that can reach the aquatic biome and are harmful to freshwater and marine communities as well…

Migrant and immigrant education are both problematic and impactful in the U.S., which often identifies itself as "a nation of immigrants", though these concepts are currently criticized by a conservative government intent on building walls rather than bridges. Nevertheless, schools throughout the country have demonstrated an ability to…

A laboratory experiment often performed in an introductory electricity and magnetism course involves the mapping of equipotential lines on a conductive sheet between two objects at different potentials. In this article, we describe how we have expanded this experiment so that it can be used to illustrate the electrostatic properties of conductors.…

Crosscutting concepts like patterns and models are fundamental parts in both the American framework of science education (from the AAAS) and our proposals for a new science education framework in Flanders. These concepts deepen the insight of both students and teachers. They help students to ask relevant questions during an inquiry and they give…

Many students (and adults) do not understand a basic tenet of energy literacy: how electricity is produced. They do not know how coal or other fossil fuels are used to make electricity, nor do they understand how nuclear power, hydroelectric power, and wind power work. The author developed a series of lessons to help students understand how…

In this study, we examined the relationship between school type and students' victimization and observations of bullying in their schools. We compared student perceptions (N = 1,283) of bullying in three urban career academies with different school configurations (e.g., magnet and school-within-a-school) and a large, urban comprehensive high…

There are many different schooling options, but not all educational choice programs are created equal. Public charter schools and public-to-public transfers, for example, have provided options within the traditional system, but those programs leave many schooling types off-limits for families. EdChoice's goal as the nation's oldest school choice…

Here we present an inexpensive proposal to experimentally study Faraday's law of induction. The experiment uses low-cost materials, a computer with a sound card and a smartphone, both running free software. A value proportional to the induced electromotive force is measured with the computer's sound card and the data related to the magnetic field…

We investigated the influence of context on students' understanding of cross products of vectors using three isomorphic multiple-choice tests asking for the direction of a cross product in different geometrical settings. One version of the test involved the Lorentz force, the second version involved the torque on an electric dipole, and the third…
