O•, O[subscript 2] and O[subscript 3] play vital roles in the Earth's atmosphere, regulating ultraviolet radiation from the Sun and being essential for life. However, the oxygen family, O•, O[subscript 2] and O[subscript 3], also provides a source of the HO radical, the atmospheric detergent that removes pollutants from the atmosphere. This…

Despite being established as genuine physical features of the universe, black holes are not well understood at a non-technical level. Basic features of black holes are outlined, a few of the more popular misconceptions surrounding them are listed and their errors identified.

With the rapid spread of high-speed railway technology, there is a resurgence of interest in trains and railways. The main propulsive engine for railways was the steam engine for over a century, which gave way to the diesel and electrical engines. The steam engine was crucial to the birth and development of the railway industry, and understanding…

Heating a fluid causes a local expansion and the resulting buoyance of the rarefied fluid drives it upward. This phenomenon roughly defines heat convection. Convection is fairly well known due to our familiarity with a large number of convection systems in open air like candles, bonfires, barbecue grills, boiling pans, hot air balloons, etc. Most…

In this paper we present a study on the capillary action of water in a glass tube. It is a well-known phenomenon that the rise of a water column in the capillary is governed by parameters such as surface tension of water, radius of the tube, density of water and acceleration due to gravity. The interdependence of the parameters gives rise to the…

This study sought to develop and evaluate an online module based on inquiry learning with digital laboratories, which was intended to address students' misconceptions in a science domain. In a quasi-experimental design, 171 first-year students in a higher education introductory physics course on circular motion were as their existing groups…

At the end of 2022, there were 2439 coal-fired power plants operating around the world, and over 7000 active coal mines (Global Energy Monitor, 2022). Coal burning was the largest source of greenhouse gases that impact climate change, and coal mining caused extensive environmental damage (US Energy and Information Administration, 2022). Decisions…

Concept mapping remains widely used in education. However, little is known about how self-constructed concept maps and peer feedback can improve student learning outcomes in chemistry. We investigated the effects of peer feedback on concept mapping and how it improves students' learning performance in a large second-semester, introductory…

Many studies have characterized students' difficulties in understanding and reasoning about scientific mechanisms. Some of those studies have drawn implications on teaching mechanisms and how to guide students while reasoning mechanistically. In this theoretical article, I claim that one component that has not garnered much attention in the…

Explaining natural phenomena by determining causal relationships is conducive to understanding scientific concepts. In science education, numerous studies examine students' causal reasoning. Given the importance of core ideas for students' understanding of how and why a phenomenon occurs, the study focused on the relationship between students'…

Circus art excites amazes and delights. Most of circus genres are based on the principles of classical physics. Dialogic discussions are known as an instrument to identify conceptual barriers (misconceptions) and facilitate their further revision. The present study integrates the three worlds: physics education, dialogic teaching and circus art;…

Cell division is one of the most relevant processes in Biology, for instance, to understand the reproduction of species or the development of tumours. Learning this content requires not addressing it out of context but integrating it into real-life problems that demand students apply their knowledge about cell division. In this study, the authors…

Several studies compared three different types of questions (conceptual, algorithmic, and graphical) across various topics, however, few focused specifically on gifted students. This study addressed this gap. The aim of the study, hence, was to determine whether there were notable differences in gifted students' performance in the three types of…

This article describes the design and evaluation of a simulation environment for special relativity (SR) education at the secondary level. In recent years, SR has become increasingly popular in secondary school curricula worldwide. Because the key concepts in SR are very remote from everyday experience, they are difficult for students to learn.…

The southernmost Thailand insurgency has increased violence since the early 2000s. It is a cause of learning loss and psychological stress among students, primarily Muslims. Having been exposed to unrest for a long time, students lack confidence and lose interest in learning many subjects, including physics. Culturally responsive teaching can…
