This paper describes two examples of teaching situations in which the idea of infinity arises, and supports the conclusion that infinity is not a physical reality but a very powerful and useful mathematical device which facilitates modelling and the solution of problems in physics.

Integrity and quality of assessments on the online platform should be upheld to ensure that it supports student learning as well as the efficacy of teaching because in the end it measures the reputation of an institution. How institutions have traversed such domains remains a grey area. This paper provides anecdotal insights into how staff from a…

Brazilian journals play an important role in the local scientific scene. Despite its importance, Brazilian scientific production in Physics and Science education needs further articulation regarding the profile and impact of manuscripts. Therefore, our main goal in this paper is to monitor the trends in the Brazilian journals from 2013 to 2019…

A single-slit diffraction experiment in an introductory physics laboratory is generally comprised of a rectangular slit and a laser source. The laser beam is sent to the slit producing the well-known diffraction pattern on the screen. This paper proposes a simple modification of the single-slit diffraction experiment to increase student attention…

There is a large variety of goals instructors have for laboratory courses, with different courses focusing on different subsets of goals. An often implicit, but crucial, goal is to develop students' attitudes, views, and expectations about experimental physics to align with practicing experimental physicists. The assessment of laboratory courses…

The Crookes radiometer (also known as a light mill) is a fascinating sunlight-powered device, in which a set of vanes is placed inside a glass bulb within which a partial vacuum has been pulled. The vanes then rotate when sunlight shines on the bulb. The reason for the turning of the vanes was subject to intense debate and many students still have…

The article describes a methodology for studying Fresnel diffraction with the active involvement of students in discussing the results of a demonstration experiment. To create a clearly visible model of Fresnel zones, a centimeter radio wave range was chosen, in which the first zone is about 10 cm in size. This makes visible the created…

This study focuses on the relationship between students' use of language resources and their conceptualisation of phenomena in producing scientific explanations in physics. The objectives are to find out if there is a general model that describe the meaning-making process, the extent that this model is applicable to various branches in physics.…

Diagrams are ubiquitous in physics, especially in physics education and physics problem solving. Physics problem solvers may generate diagrams to orient to a scenario, to organize information, to directly obtain an answer, or as a tool of communication. In this study, we asked 19 undergraduate and graduate physics majors to answer 18…

This study aimed to investigate the effects of feedback types and opportunities to change answers on the learners' achievement and their ability to solve physics problems. We compared three feedback types, namely (1) static feedback with hints, (2) reducing feedback with hints, and (3) knowledge of response, and two types of opportunities to…

Given that many models of design-based learning in science education are grounded in forward engineering, in which students are challenged to use the engineering design process to achieve unknown solutions to engineering problems, this study aims to examine the potential of using reverse engineering, as an alternative approach to design-based…

We propose a laboratory experiment on the quantitative study of the normal dispersion of light. A triangular isosceles prism made of flint glass TF3 is used as the object of study, and we describe a simple and affordable device for observing and photographing the dispersion spectrum on a smartphone. A possibility of the quantitative investigation…

Even though many physics teachers take their students on a calculation adventure through circular motion and Newton's universal law of gravity to determine Earth's velocity, most of us leave it at that. We present the final result and say, "Look, Earth is moving around the Sun at about 107,000 km/hr (66,000 mph), yet we can't feel the motion…

The integration of physics, music, and mathematics has long been used to increase students' interest and motivation in these subjects. For example, previous articles in this journal have shown how to teach physical concepts in a musical context, use a smartphone to check the resonant frequencies of whistles, use a smartphone to examine the spectra…

"Ulysses" by James Joyce (1882-1941) has a surprising amount of 19th-century, classical physics. The physics community is familiar with the name James Joyce mainly through the word "quark" (onomatopoeic for the sound of a duck or seagull), which Murray Gell-Mann (1929-2019 -- Physics Nobel Prize 1969) sourced from Joyce's…
