A popular introductory physics laboratory experiment is one focusing on Snell's law. This is straightforward to complete with lasers and prisms, but here we present an alternative version that guides the students through some of the major historical developments, recreating and analyzing significant experiments. The discovery of Snell's law has a…

In this work, a simple rocking pendulum, in a circular arc shape, is presented. The idea is to put a rigid arc on a clean flat surface of glass and leave it to oscillate under the effect of a little impulse. Then, the periodic time of this arc pendulum's motion is experimentally determined. The mathematical analysis of the arc's motion is derived…

The possibility of conducting laboratory experiments at home without using commercially available kits, which might also be overly expensive, seems to be a suitable approach for a distance chemistry laboratory. Thus, several hands-on experiments with household supplies have been developed aiming at fostering students' laboratory competencies, as…

So-called "Color Wonder" markers contain colorless dyes that only display color when used to mark on special "Color Wonder" paper. These markers make use of leuco dyes that only develop color in the presence of acid. These markers provide science educators with a novel chemical system that can be implemented in inquiry-based…

Nonlinear chemical reactions produce interesting chemohydrodynamic patterns in an unstirred medium, which act as interesting demonstrations to display the novel phenomena in a nonequilibrium chemical system. Here, we report new outreach experiments: pH chemohydrodynamic patterns modulated by sodium polyacrylate in the bromate-sulfite-ferrocyanide…

Raman scattering spectroscopies are important analytical tools in modern chemistry. Here, we describe the construction of the unamplified Raman scattering analysis (URSA) instrument: an inexpensive, open-table Raman spectrometer that uses a 532 nm diode-pumped laser as a light source. Upon application of this spectrometer to DNA extracted from…

Students' out-of-school science participation has been identified as a factor that supports adaptive science outcomes. Researchers have largely investigated students' out-of-school science participation in terms of structured science activities (e.g., attending a science camp), with far less consideration of how students' involvement in…

With the global increase of infections caused by antibiotic-resistant bacterial strains, there is an urgent need for new methods of tackling the issue. Genomic analysis of bacterial strains can help to understand their virulence and antibiotic resistance profile. Bioinformatic skills are in great demand across the biological sciences. We designed…

Background: To contribute to smart, inclusive, sustainable, and multisensory practices in science education, this paper presents research that studied the use of electronic sensors by children to address a sound pollution problem in their school. A didactic sequence was specifically designed and implemented to that purpose. Participants: The…

This research was conducted to examine the effects of the socioscientific issue approach (SSI) with thinking wheel map (TM) on entrepreneurial science thinking (EST) and the constructs of Observation, New Ideas, Innovation, Creativity, and Value. A teaching and learning (TL) module was developed to guide teachers in implementing the infusion of…

Higher education biology is often imagined, perceived, and described as having reached gender equality in terms of who gets to participate in disciplinary practices. However, like any other natural science discipline, higher education biology is a world whose landscapes are shaped by (re)productions of historical, cultural, and social norms. We…

Physics education has been identified as one of the public sectors that are mostly influenced by technological developments. This paper adopted the quasi-experimental pre- and post-test design to assess the effects of multimedia-aided technologies (MAT) on undergraduate students' performance in quantum physics (QP) at the University of Rwanda…

The historical dimension of biology attests to the various conceptions of living organisms that have governed the construction of scientific knowledge over time, some of which still persist today. The present study aimed to identify and characterise the various conceptions of living organisms held by future teachers and biologists and the…

Uncertainty tolerance, individuals' perceptions/responses to uncertain stimuli, is increasingly recognized as critical to effective healthcare practice. While the COVID-19 pandemic generated collective uncertainty, healthcare-related uncertainty is omnipresent. Correspondingly, there is increasing focus on uncertainty tolerance as a health…

In theory, there is broad agreement among science education stakeholders that supporting the achievement of scientific literacy is crucial for citizens to make informed and critical decisions about socioscientific issues (SSI). Likewise, it is widely held that argumentation is an important component of scientific literacy. In practice, however,…
