Previous studies have demonstrated that students have difficulties in applying the wave model of light to explain single-slit diffraction and double-slit interference patterns. In this study, we investigated if students could recognize typical interference and diffraction patterns at all. Eye movements of high-school students were measured while…

Light rays refract when passing through pockets of transparent fluids with different indices of refraction such as ordinary air pockets of varying temperature. This phenomenon makes night stars twinkle, distorts views above hot asphalt roads and hot barbeque grills, and provides an opportunity for visualizing the normally invisible movement of…

The topic of atomic spectra is part of university and secondary school curricula around the world. Relatively little research, however, has been done on the learning and teaching of this subject, despite the fact that it forms a foundation for advanced study in quantum mechanics, astronomy, and astrophysics. A systematic investigation into student…

This article showcases how a Wi-Fi based LED light system that flickers to indicate probability of auroral manifestation became a beacon of inquiry, interest, and critical thinking amongst preservice teachers, staff, and passersby in a teacher education program. Beyond articulating the design phase of the system, highlighted here are the three…

The research study concentrates on the incorporation of case technology to augment the enhancement of research competencies among future physicists. The study scrutinizes the influence of case technology on students' research capabilities and their aptitude to apply theoretical knowledge to practical situations. The main objective was to identify…

Integrated science, technology, engineering, and mathematics (iSTEM) education allow learners to utilize multiple disciplinary perspectives. However, the discipline of mathematics remains underrepresented in iSTEM curriculum. To explore the nature of mathematical thinking with an iSTEM curricular approach that emphasizes mathematics, we…

The COVID-19 pandemic has emphasized the importance of designing effective methods for remote teaching. At the University of California, Berkeley, and the University of California, Santa Cruz, instructors adapted to the necessity of remote laboratory instruction by creating choose-your-own-adventure-style video-based online experiments introduced…

Photonics is an emerging field of science and technology that is effective in providing sustainable and innovative solutions to twenty-first century problems. Science education includes topics related to light. However, photonics is not yet included in most school curricula as a subject within the domain of science and technology to be presented…

We present a simple and cheap experimental setup that clearly shows how the colors of the white light spectrum after passing a prism do not recombine when emerging from an identical second prism, as it is still found in many references.

Malus's law states that the intensity of light after passing through two polarizers is proportional to the square of the cosine of the angle between the polarizers. We present a simple setup demonstrating this law. The novelty of our work is that we use a multi-turn potentiometer mechanically linked to one of the polarizers to measure the…

The peak position of the spectral density for blackbody radiation is given by the Wien displacement law. Within introductory physics materials it is often stated, or implied through example, that the color of the light emitted from a blackbody, such as the Sun, can be ascertained from knowledge of the position of that peak in the spectral density.…

Game-based learning in science education is an effective method to enhance students' motivation, active participation, and conceptual understanding of the scientific knowledge. This study aimed to encourage teachers to develop and use game-based activities related to the concepts of light and sound and to present students' views about the games…

It is well established that drawing upon students' Funds of Knowledge (FoK) supports powerful learning outcomes, especially for youth whose life experiences are not always valued in dominant classroom spaces. Yet, teachers can struggle to find ways to do so (Gonzalez, Moll, and Amanti 2005). In this article, the authors introduce an…

A fluorometer is a device that measures the spectroscopic properties of fluorescent materials, and fluorometry is used widely in chemistry research settings to characterize fluorescent samples. One of the obstacles faced by undergraduate programs looking to implement fluorometer-based experiments into their laboratory curriculum is the high cost…

In times of the explosion of distance learning, because of emergency due to the pandemic, smartphone sensors and cameras are extremely valuable for teachers as they allow students to perform significant experimental activities in their own homes. The open-source software Tracker can be used in combination with the smartphone camera to perform…
