Research-based assessments represent a valuable tool for both instructors and researchers interested in improving undergraduate physics education. However, the historical model for disseminating and propagating conceptual and attitudinal assessments developed by the physics education research (PER) community has not resulted in widespread adoption…

South Korean high school students are being taught Einstein's Special Theory of Relativity. In this article, I examine the portrayal of this theory in South Korean high school physics textbooks and discuss an alternative method used to solve the analyzed problems. This examination of how these South Korean textbooks present this theory has…

For acquainting the students of applied physics and students of teaching physics with the concept of energy efficiency, electrical and spectral characteristics of two widely used lamps--integrated fluorescence lamp and common light bulb have been investigated. Characterization of the lamps has been done by measuring the spectral irradiance and…

It is hard to observe relativistic effects in everyday life. However, table experiments using a mechanical transmission line for solitons may be an efficient and simple way to show effects such as Lorentz contraction in a classroom. A kink soliton is a deformation of a lattice of several dozen or more pendulums placed on a wire and connected by a…

I describe a simple and fascinating experiment wherein helium leaks out of a rubber balloon, thereby causing it to descend. An estimate of the volumetric leakage rate is made by measuring its rate of descent.

Physics is a tough and challenging topic. Facilitating the learning of physics requires an innovative and constructivist view of teaching that promotes an active learning environment and an effective implementation of educational technology. The purpose of the study is to investigate whether the use of computer simulations combined with hands-on…

Formulating questions is an integral part of pupils' learning process and scientific inquiry. Investigating pupil-generated questions in a collaborative science learning setting, combining self-regulation theory and phases of inquiry, can extend the previous research into pupils' questions.This study considered questions from pupils (n = 24, aged…

This study was carried out to determine the effect of guided inquiry teaching method (GITM) on secondary school students' achievement in light and sound waves in Abuja, Nigeria. A sample of 95 students drawn from a population of 1,832 was used for the study. Two research questions were raised and answered in the study using mean and standard…

Understanding the ways in which Black folks identify as physicists can provide useful information about the facets of the physics discipline that perpetuate systems of oppression. In prior work, we developed the critical physics identity (CPI) framework to identify the structures and systems that impact the ways that people identify with the…

In this paper, we present the details of the development of a smartphone spectrometer for education using a 3D printer and characterized the performance by comparison with a paper craft spectrometer. The optical design and the narrow slit used in the build resulted in the formation of accurate images of the slit on the image sensor leading to a…

This article is about the development of an Internet-based remotely-controlled physical experiment, this is a part of the Remotely Controlled Laboratory at the University of Applied Sciences of Cologne known as TH Köln. The main experimental set-up is based on Pohl's Torsion Pendulum which was enhanced by a PXI measurement system and a webcam. In…

This paper is the second part of a three-paper series. It describes a project based approach to STEM enrichment and presents a detailed description of the practical set-ups, the investigations carried out by the students and their experimental findings. The accompanying first paper outlines an introductory gravitational waves based teaching module…

This paper reports the results of a research exploring the mathematical connections of pre-university students while they solving tasks which involving rates of change. We assume mathematical connections as a cognitive process through which a person finds real relationships between two or more ideas, concepts, definitions, theorems, procedures,…

Background: Students' well preparedness for laboratory sessions is of importance for a number of reasons including them being able to engage in and learn from the session and in acquiring the necessary laboratory skills needed for the scientific community and for possible further work in industry. To enhance the preparedness of the students an…

This study aims to examine students' reasoning based on the model in each laboratory work style and find the effect on scientific attitude and student activity. This study uses a quantitative approach with the experimental method. The study was conducted in three classes with different lab work styles. Arduino and sensors were used as a…
