A fairly recent paper resolves a large discrepancy in the internal energy utilized to fire a cannon as calculated by two inertial observers. Earth and its small reaction velocity must be considered in the system so that the change in kinetic energy is calculated correctly. This paper uses a car in a similar scenario, but considers the work done by…

There are five unique points in a star/planet system where a satellite can be placed whose orbital period is equal to that of the planet. Simple methods for calculating the positions of these points, or at least justifying their existence, are developed.

We describe the kinematics, dynamics, and also some energy issues related to Marta mouse's motion when she walks on top of a horizontal bicycle wheel, which is free to rotate like a merry-go-round, as presented recently by Paul Hewitt in the "Figuring Physics" section of this journal. The situation is represented in Fig. 1, which was…

Education for sustainable development is an emerging concept that encompasses a new vision in physics education that empowers the learner to assume responsibility for creating a sustainable future. Physics education is still struggling to adapt to the personalized approach in learning. Personalized learning thrives in this technology-rich…

PhysPort (www.physport.org) has become the go-to place for physics educators to learn to apply research-­based teaching and assessment in their classrooms. Usage (defined as the total number of visits) has doubled every two years since the site was released in 2011, and 20% of all U.S. physics faculty and 7% of U.S. high school physics teachers…

The Physics Laboratory of the Hellenic Open University has constructed a small scale and low cost air shower detector suitable for operation inside the classroom or school laboratory ([mu]Cosmics detector). In this work we present some of the educational activities foreseen with the [mu]Cosmics air shower detector, as well as the assessment of a…

Since the 1980s, studies have increasingly shown that traditional teaching causes a deterioration in students' conceptions of physics and of learning physics. The present study examined the influence of an intervention on high school students' conceptions of physics and of learning physics. The intervention included two components: a unique design…

The NASA public archives present a vast resource of authentic satellite data that research astronomers have tapped into for decades. Recently, the same data analysis tools used by professional astronomers have been adapted into a browser-based interface called JS9 for easy use by any interested student. Tutorials and classroom-ready activities…

One of the many ways issues of underrepresentation appear in the physics classroom is female students frequently have a lower perception of their performance and ability than their male peers. Understanding how classroom experiences impact students' confidence, especially for underrepresented students, can provide an important guide to designing…

This is a theoretical paper in which we describe the motivation for and the design of a novel primary physics course for student teachers at kindergarten and primary school levels that uses cognitive tools such as metaphor, analogy, and narrative. The course has been taught in the master's program in teacher education at three Universities over…

Physics education research (PER) has long used concept inventories to investigate student learning over time and to compare performance across various student subpopulations. PER has traditionally used normalized gain to explore these questions but has begun to use established methods from other fields, including Cohen's "d," multiple…

Since concept cartoons give an important opportunity for students to achieve informal physics learning, the current research focused on pre-service teachers' initial impressions of the concept cartoons in the school corridors and informal physics learning. The aim of the research was to determine pre-service teachers' initial impressions of the…

This study explores prospective primary school teachers' misconceptions concerning basic concepts in chemistry. The data was gathered during the years 2012-2016 among first-year primary school teachers in Finland (N = 389). The results show that every year, as many as 40%-80% of teachers share the same kinds of misconceptions as children ages 5-12…

Purpose: The aim of this study was to determine changes in swimming parameters, stroke coordination, and symmetry after repeated high-intensity swimming efforts in swimmers of different performance levels and para-swimmers. Method: Forty swimmers (20 able-bodied, allocated to higher and lower performance groups--G1 and G2, respectively--and 20…

We describe the development and in-class evaluation of a quantum interactive learning tutorial (QuILT) on quantum key distribution, a context which involves an exciting application of quantum mechanics. The protocol used in the QuILT described here uses single photons with nonorthogonal polarization states to generate a random shared key over a…
