In this article, we describe how the Gaussian Gun, a simple configuration of magnets and ball bearings, can be leveraged to connect ideas from physics to representations and ideas that are central to chemistry and challenging for students to learn. In particular, we show how the Gaussian Gun, an arrangement of ball bearings and magnets, models…

Electrostatic potential energy is a topic of great difficulty for many students. In this paper, we empirically test the utility of two approaches for laying a foundation for developing an understanding of energy in an electrostatic context, with interdisciplinary relevance. We examine student responses to a question about how the potential energy…

This brief examines school integration and school choice through the lens of school transportation. It first provides a brief history of the role transportation has played in integration and choice policies. It then dives into three examples of initiatives that combine choice and integration, and the challenges they pose for transportation,…

Electromagnetic radiation is one of the most important issues affecting peoples' lives today. The misunderstanding of students and the general population of the effects of electromagnetic radiation is a problem which must be eliminated. Thus, a discussion about ionising and non-ionising radiation focusing on the crucial issue of radiation emitted…

Magnetism is traditionally taught within the subject of electromagnetism at the undergraduate and graduate levels in physics courses, with the goal of establishing a solid foundation of the underlying physical mechanisms before advancing to more specialized topics. Oftentimes, a laboratory component of these courses involves practical, hands-on…

The internal sensors in smartphones for their advanced add-in functions have also paved the way for these gadgets becoming multifunctional tools in elementary experimental physics. For instance, the acceleration sensor has been used to analyze free-falling motion and to study the oscillations of a spring-mass system. The ambient light sensor on…

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…

Access and performance in advanced high school physics have been persistently inequitable when considering student ethnicity and gender. This quasiexperimental, observational study examined access and performance of students in four Advanced Placement (AP) Physics courses in 2018-2019: AP Physics 1 (N = 150 451), AP Physics 2 (N = 20 466), AP…

While the use of experiments is important for developing students' scientific knowledge and skills, challenges may arise when teachers and students are conducting experiments in class, such as non-reusable experimental resources, safety issues and difficulties simulating some specific effects. Augmented reality (AR) technology affords an…

The Conceptual Survey of Electricity and Magnetism (CSEM) is a widely used multiple-choice instrument measuring a student's conceptual understanding of electricity and magnetism. This study applied modified module analysis (MMA) and modified module analysis-partial (MMA-P), network analytic methods that identify groups of correlated responses, to…

This article presents a qualitative study of the type and quality of questions formulated by prospective elementary teachers (PETs) when designing scientific inquiry activities, depending on the school science content selected. The data were acquired during teacher training instruction on these aspects with 67 participant PETs. The results showed…

This paper emphasizes the possibilities and effects of using research approach (discovering scientific concepts through play) as one of the innovative ways of teaching pre-school children. Apart from the fundamental characteristics and importance of using research approach, the paper also presents the results of an empirical research aimed at the…

In this work we present the application of design based research (DBR) methodology to conduct a systematic iterative study of the design and implementation of a teaching-learning sequence (TLS) on emf (electromotive force). This work is the final part of a broader study that started with the analysis of students' difficulties with emf in the…

The objective of this study is to design a temperature measurement system based on a non-contact method using a sensor camera from a webcam. The material being measured is nickel wire given an electrical current of 4.5 A-6.5 A with an interval of 0.5 A. The temperature measurement is based upon the measurement of the average pixel value…

The creation of specialty science, technology, engineering, and math (STEM) Schools has been presented as a way to improve both academic and STEM-related outcomes, particularly in urban school districts where "failing" schools are converted the STEM Schools. This study examines this conversion process through the tenets of critical race…
