A major consequence of special relativity, expressed in the relation E[subscript 0] = mc[superscript 2], is that the total energy content of an object at rest, including its thermal motion and binding energy among its constituents, is a measure of its inertia, i.e., its mass. This relation was first stated by Einstein. He showed that, in order to…

Usually parametric oscillations are not the topic of general physics courses. Probably it is because the mathematical theory of this phenomenon is relatively complicated, and until quite recently laboratory experiments for students were difficult to implement. However parametric oscillations are good illustrations of the laws of physics and can be…

The "Playground Physics" program combines informal, play-based, embodied learning experiences to support middle school students' engagement with and motivation to learn about complex and abstract physics concepts. This experimental design study examines the impact of "Playground Physics" on students' science motivation,…

In this study, we evaluate the impact of rehearsing teaching skills in a mixed-reality classroom simulator on graduate teaching assistants' (GTAs) instructional practices as well as undergraduate student learning outcomes. The simulator training is intended to provide GTAs opportunities to deliberately practice essential pedagogical skills that…

Polar research plays a vital role in developing our understanding of Earth's climate system. It is intrinsically interdisciplinary, lending itself to integration into existing undergraduate courses. Here we explore introducing undergraduates to polar research through computational guided inquiry (CGI) modules taught in a variety of courses and…

There is a worldwide concern about science and engineering undergraduate students, particularly those who are English language learners, struggling with their entry-level content courses. From a teacher cognition perspective and drawing on semi-structured interviews with chemistry, mathematics and physics teachers at a university in the Middle…

Representational competence is essential for the acquisition of conceptual understanding in physics. It enables the interpretation of diagrams, graphs, and mathematical equations, and relating these to one another as well as to observations and experimental outcomes. In this study, we present the initial validation of a newly developed…

We surveyed a convenience sample of 362 Italian university physics students, asking them to retrospectively assess their experience of emergency remote instruction due to the COVID-19 outbreak. We looked at their psychological well being, motivation for physics, academic orientation, attitude towards physics and physicists, and tried to link these…

This study examined outcomes for AP® Calculus and AP Physics students on the 2015 Trends in International Math and Science Study (TIMSS) relative to other participating countries and other advanced math and science students in the United States. Compared to other countries in the study, AP Calculus BC and AP Physics C: EM students outperformed all…

Labs have long been considered an important component of physics education. However, while there has been progress in transforming physics education in physics lecture classes to improve student learning, less progress has been made in introductory physics labs. At the same time, the physics community has come to recognize that there is a need to…

It has been illustrated several times how the built-in acceleration sensors of smartphones can be used gainfully for quantitative experiments in school and university settings (see the overview in Ref. 1 ). The physical issues in that case are manifold and apply, for example, to free fall, radial acceleration, several pendula, or the exploitation…

Ferromagnetic materials such as nickel, iron, or cobalt lose the electron alignment that makes them attracted to a magnet when sufficient thermal energy is added. The temperature at which this change occurs is called the "Curie temperature," or "Curie point." Nickel has a Curie point of 627 K, so a candle flame is a sufficient…

Although we experience motion simply as displacement, we study it through complicated concepts such as acceleration, force, and mass, departing from our everyday experience. But it looks like we can stay attached to our primordial notions of time and length without appealing to any other concepts and still have interesting results.

This work reports a classroom experience of a general physics course designed to foster also the initiation of preservice mathematics and biology teachers to physics pedagogical content knowledge. To modify the conceptions that these students have about teaching and learning, the course was taught using different active learning instructional…

With COVID-19 pandemic forcing academic institutions to shift to emergency remote teaching (ERT), teachers worldwide are attempting several strategies to engage their learners. Even though existing research in online learning suggests that effectiveness of the online session is more dependent on pedagogical design rather than technology feature,…
