This study investigates children's science learning in a nursery in Turkey. The participating children (aged 5 and 6) are from a socio-economically disadvantaged community. This is an ethnographic study that includes participant observations and audio recordings of classroom interactions based on a long-term basis. It takes a socio-cultural…

Solar limb darkening is a prominent feature seen in white images of the Sun: the brightness of the solar disk is greatest at the solar center and decreases radially outward towards the limb. White light images can be used to examine and even model limb darkening; however, the limb-darkening effect is, in fact, wavelength dependent. Limb darkening…

The cases of constant and quadratic damping of free oscillations are missing from standard textbooks, even at college and university level. The case most examined is that of linear damping, the reason being that the student can work out a closed form which describes all stages of motion. The case of constant damping is straightforward to be…

This study aimed to determine the influence of critical thinking skills on misconceptions using a five-tier instrument in mixed-method research. The sampling technique used is simple random sampling. The data collection instrument used a critical thinking skills questionnaire, a misconception test of electric field material, and interviews. Data…

A significant challenge physics faculty face teaching introductory labs is engaging students in authentic science practices. Another has been highlighted given the current global pandemic--how to engage students in our laboratory courses while maintaining appropriate social distancing and hygiene standards. We have chosen to answer these…

In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

The Wilson cloud chamber, invented in 1911 by Scottish physicist Charles Wilson, is a remarkably simple and effective charged particle detector. Cloud chambers were used regularly in particle physics experiments for decades, until being supplanted by bubble chambers. In this article, we describe a lab activity that is suitable for…

Combining mathematical and physical understanding in reasoning is difficult, and a growing body of research shows that students experience problems with the combination of physics and mathematics in reasoning beyond the introductory level. We investigated students' reasoning about boundary conditions (BCs) for the diffusion equation by conducting…

History of education reveals that the perimeter of a school subject as well as the manner of teaching it may vary according to the time period, the country, its political situation and its economic needs. Furthermore, if it clearly depends on the level of the learners and on the school itself, sometimes the teacher's preoccupations can adapt it.…

Visual representation in school textbooks plays an important role for physics teaching and learning. The integration of graphics with text has drawn attention of physics educators in recent years due to the close relationship between graphics and relevant text. The purpose of this study is to examine visual representation of optical content in…

The analogy among momentum, heat and mass transport phenomena is an important concept in chemical engineering education. This paper presents the analogy between heat exchanger and packed column calculations. The effectiveness-NTU method used to calculate outlet temperatures of hot and cold streams in an exchanger is introduced in a packed column…

Badges in education are an increasingly popular phenomenon, and a variety of questions exists as to the abilities and effectiveness of badges. In this study, the effect of digital badges within a Moodle-based online homework system was studied for an undergraduate general physics course at a large research-based university in northeast Taiwan. One…

An absorption line at 900 nm has been observed in Perspex. Samples of 1 and 2 cm thickness were used and the integrated absorption (line width times peak absorption) of the line was proportionate to the thickness. Facilities for lowering the sample temperature were not available and therefore both measurements were carried out at room temperature.…

Nowadays, students have digital skills that are much larger than any other student in the past. Traditional experiments in a real laboratory are still fundamental, however an increasing number of computers can be used to simulate experiments close to the experimental environment. This can be seen as a great advantage for science learning, as…

LGBT+ persons in science, technology, engineering, and mathematics have a small growing body of literature addressing their experiences and workplace concerns. This study offers workplace climate analysis of 324 survey respondents in the field of physics. The findings indicate that when building a climate model to predict for consideration to…
