We conducted a study with introductory and upper-division level physics students in a Mexican and a Spanish university to learn how students recognize the main characteristics of the electric field in three of its more widely used representations, namely, algebraic notation, vector field plot, and electric field lines, and how the students do…

This article describes the development and deployment of Physics Toolbox Play, a gamified component of the "Android Physics Toolbox Sensor Suite" app, that can introduce young children through adults to fundamental physics principles. The app was used successfully in a variety of contexts, including STEM fairs with primary and secondary…

Driven by our technologically advanced workplaces and the surge in demand for proficiency in the computing disciplines, it is becoming imperative to provide computational thinking (CT) opportunities to all students. One approach for making computing accessible and relevant to learning and problem-solving in K-12 environments is to integrate it…

In the spring of 2018 the Northern California/Nevada Section of the American Association of Physics Teachers was alerted to a local high school's plans to eliminate physics for the following school year. As part of the campaign to support the school's efforts to sustain physics in the following year, the physics offerings from the surrounding…

The private company SpaceX regularly launches satellites into geostationary orbits. SpaceX posts videos of these flights with telemetry data displaying the time from launch, altitude, and rocket speed in real time. In this paper this telemetry information is used to determine the velocity boost of the rocket as it leaves its circular parking orbit…

Research-based assessment instruments (RBAIs) are ubiquitous throughout both physics instruction and physics education research. The vast majority of analyses involving student responses to RBAI questions have focused on whether or not a student selects correct answers and using correctness to measure growth. This approach often undervalues the…

This study aimed at investigating the issue of domain specificity of motivation across specific science disciplines (chemistry and physics) in combination with influencing factors related with students' academic major and gender. A clustered sampling was used to select 281 participants who were undergraduate students (105 males and 176 females)…

The use of smartphones in experimental physics is by now widely accepted and documented. PASCO scientific's smart cart, in combination with student-owned smartphones and free apps, has opened up a new universe of low-cost experiments that have traditionally required cumbersome and expensive equipment. In this paper we demonstrate the simplicity,…

Students hold many alternative conceptions of thermal physics which are very resistant to change. A conceptual change strategy, the thinking frames approach, based on evidence from educational research was used to address commonly held naïve conceptions about heat in a series of thermal physics lessons. Students' gains in conceptual understanding…

Dark matter comprises most of the matter in the universe, yet physicists are unsure of its nature. A significant effort is devoted in contemporary research to attempts to understand dark matter, making it a both captivating and relevant area of astrophysics to discuss in a classroom setting. What is more, the physics behind these experiments is…

The analysis of the Test Instruments' quality is a crucial thing needs to be conducted. The test instruments made by teachers must fulfil the requirements (validity, reliability, and standard error of measurement) until the measurement result obtained can describe the students' actual abilities. This research aims to analyse the content validity…

We report the findings of an empirical study that investigated whether the source of data--firsthand or secondhand data gained from lab work experiments--has an influence on students' learning outcomes. Results indicate that students' choice of a correct or incorrect hypothesis for a pendulum lab experiment on the influence of the mass of the bob…

The so-called Diet Coke and Mentos experiment is initiated by dropping Mentos candies into a bottle of Diet Coke or other carbonated beverage. This causes the beverage to rapidly degas, causing foam to stream out of the bottle. Simple application of the gas laws leads to the straightforward prediction that ejection of greater foam volume is…

This research aims to develop a falling chain experiment apparatus using kitchen scales and digital cameras (smartphones). Digital cameras were used to observe and record changes in the mass of falling chains measured using kitchen scales. Video recordings from observations of falling chain masses were analysed using Tracker 5.1.1 software. The…

The South African Department of Education has attributed the poor pass rates in Grade 12 Physical Sciences to the learners' lack of practical work and the inability of learners to solve problems by integrating their knowledge from different topics in Physical Sciences. A possible reason for this could be a disjointed alignment between the…
