This work deals with the experimental demonstration of coupled oscillators using simple tools in the form of mechanical coupled pendulums, magnetically coupled elastic strings or electromagnetic oscillators. For the evaluation of results the data logger Lab Quest Vernier and video analysis in the Tracker program were used. In the first part of…

Micrometeorites originate from small pieces of rock from space colliding with the Earth's atmosphere at high velocity, such as the Perseid meteors which hit the atmosphere at 60 km/s. When they do so, they burn up, causing a flash of light that we see as a meteor. Many groups have been successful collecting these particles using various devices.…

As presented in physics textbooks, as well as in a few papers, the typical example of an induced motional electromotive force e[subscript mot] = "Blv" consists of a conductive rod of length "l" frictionlessly sliding with speed v along parallel wires within an orthogonal and constant uniform magnetic field of magnitude…

Using a Critical Race Theory framework, this manuscript examines the scholarly literature on the intersection of tracking and its historical use as a method for establishing and maintaining racial segregation in American public schools. I begin by exploring accounts of tracking in American public educational institutions as researched by…

A physical pendulum with a magnetic load is proposed for comparison of linear and nonlinear oscillations. The magnetic load is repelled by permanent magnets which are disposed symmetrically relative to the load. It is established that positions of the pendulum and the magnets determine the dependence of restoring force on displacement of the load.…

Laboratory experiments that demonstrate the effect of paramagnetic complexes on chemical shifts and relaxation times of protons are a useful way to introduce magnetic resonance spectroscopy (MRS) probes or magnetic resonance imaging (MRI) contrast agents. In this undergraduate inorganic chemistry experiment, a paramagnetic Co(II) cage complex is…

The International Technology and Engineering Educators Association (ITEEA) defines STEM as a new transdisciplinary subject in schools that integrates the disciplines of science, technology, engineering, and mathematics into a single course of study. There are three major problems with this definition: There is no consensus in support of the ITEEA…

The research investigated the effect of a science diagram on primary students' conceptual understanding about magnets. Lack of research involving students of primary age means that little is known about the potential of science diagrams to help them understand abstract concepts such as magnetism. Task-based interviews were conducted individually…

Students in racially and socioeconomically integrated schools experience academic, cognitive, and social benefits that are not available to students in racially isolated, high-poverty environments. As Americans consider the consequences of an education system that increasingly sorts students by race and class, it is also important to recognize the…

Many science curricula and standards emphasise that students should learn both scientific knowledge and the skills associated with the construction of this knowledge. One way to achieve this goal is to use inquiry-learning activities that embed the use of science process skills. We investigated the influence of scientific reasoning skills (i.e.…

This study investigated how integrating social justice issues, STEM practices, and mathematics may support equity in mathematics education. We analyzed video of four lessons focused on inverse trigonometry and disability rights from a STEM project-based geometry class. Using an established observation protocol, we identified themes related to…

Electromagnetic induction is an important, yet complex, physics topic that is a part of Croatian high school curriculum. Nine Croatian high school students of different abilities in physics were interviewed using six demonstration experiments from electromagnetism (three of them concerned the topic of electromagnetic induction). Students were…

The purpose of this quantitative record of study was to explore the relationship between performance on EBRW scores on the SAT and participation in dual credit, advanced placement, or on-level junior English coursework. In addition, the relationship between participation in a collegiate academy magnet program and SAT performance was also of…

There is well-documented research and data that echo the concern for the future of United States' ability to globally compete in science, technology, engineering, and mathematics (STEM) innovation and to fulfill the shortage in talent that exists within this field of study. This concern compels us to seek more impactful and long-term solutions to…

School-Wide Positive Behavioral Interventions and Supports (SWPBIS) is a broad set of evidence-based strategies designed to create school environments that promote and support appropriate behavior of all students. The "PBIS Cultural Responsiveness Field Guide" provides a foundation for designing a SWPBIS program that meets the needs of…
