Semiconductor devices, usually made from silicon wafers, are present in the electronic gadgets that we use on a daily basis. In an introductory physics class, the textbook usually devotes a few pages to these devices and moves on. As a result, students may readily forget the material or fail to see how it relates to their lives. A solution is to…

Heat transfer is a phenomenon well known from everyday life. It is intuitively connected to the properties of materials, that is, to the physics concept of thermal conductivity relevant for cooking or maintaining the constant temperature in rooms, even without being familiar to the underlying physics. However, measurement of thermal conductivity…

Keto-enol tautomerism is a fundamental concept that examines the migration of a proton between two constitutional isomers, the keto and enol tautomer. Many experiments have been proposed to understand the concept behind Meyer's Rule, which states that the keto tautomer is favored as the solvent polarity increases. However, all the experiments have…

Our aim in this paper is to describe an opportunity for physics students and faculty to learn about an environmental issue of much current interest: the quantification, or footprint analysis, of carbon dioxide (CO[subscript 2]) and reactive nitrogen emissions. These can originate from human activities such as energy use, food consumption, and…

This note is about 1000 words in length. We have been taught that this much information is contained in a single picture. But, Fig. 1 is so rich that four separate ideas can be obtained from it! The figure appears in "The Boy's Playbook of Science" by John Henry Pepper. Pepper tells us that this shows an "assistant standing on the…

The purpose of this study is to reduce ethics violations such as tricking and cheating that may occur in the offline assessment of undergraduate level Physics-II (Electricity) course subjects. The study is significant for the reliable and ethical evaluation of the Internet and computer-based educational process. Thirty-eight pre-service teachers…

This chapter illustrates the main warning signals that could help us to detect the flaws of an explanation in physics: internal contradiction (two examples); direct contradiction of a law of physics (one example); indirect contradiction of a law of physics (one example); logical incompleteness of an explanation (three examples); overgeneralization…

The COVID-19 pandemic posed significant challenges for practical teaching within the sciences. While many instructors adopted innovative alternatives to conventional practicals, many relied on digital approaches that did not give students hands-on experience. In this study we evaluate the use of 'at home' practical kits used in first year physics…

Teachers' goals and orientations underlie their instructional decision making and can make the difference between "talking the talk" and "walking the walk" when trying to change lab instruction. Schoenfeld's "Resources, Orientations, and Goals" (ROG) framework was employed to shed light on the challenges involved in a…

This research investigated how freshman students' epistemological beliefs in physics are impacted by gender and academic performance in a general physics course. Data were collected from 1220 university freshman students from 22 different programs in Türkiye. In this causal-comparative research, the well-known Colorado Learning Attitudes about…

The Interactive Whiteboard as a teaching tool, has been in use across schools and institutions in many countries. Bhutanese schools started using them for educational purposes in 2019. However, there is lack of evidence on their actual use and effectiveness in teaching physics to enhance students' learning. This study aimed to investigate the…

Traditional, template physics labs are often associated with student dissatisfaction and superficial applications, and are known to leave students with fragmented knowledge. An alternative known as labatorials, a conceptually driven approach to labs, has been proposed. In a number of studies, labatorials have been shown to work well. However, what…

In this study, we investigated the validity of a stealth assessment of physics understanding in an educational game, as well as the effectiveness of different game-level delivery methods and various in-game supports on learning. Using a game called "Physics Playground," we randomly assigned 263 ninth- to eleventh-grade students into four…

This article reports on a study that examined papers written by graduate students in the Physical Seminary course at Johns Hopkins University (1892-1913) to investigate how students reused various visuals of the interferometer to construct narratives of late-19th-century Ether research. Their representations of the interferometer focused on the…

The concept of black body is of primary importance in studying the energy transfer of thermal electromagnetic radiation at all wavelengths. Several physical bodies like incandescent lamps, electric heaters, stoves, the sun and the other stars, microwave background radiation, etc., are considered to be black bodies as their radiation spectra fits…
