The study explores the students' engagement in the school garden through mushroom farming resulting in reorienting science pedagogy. It particularly reconnoiters the interconnection between entrepreneurship skills through mushroom farming and the pedagogy for the basic-level public schools of Nepal. Also, the study explores the science pedagogical…

Education 4.0 has emerged as a response to the Industrial Revolution 4.0, focusing on integrating technology into learning to support digital transformation and enhancing 21st-century skills, such as critical thinking, creative thinking, communication, and collaboration. While technology provides convenience, it also challenges students to develop…

This study investigates the utilisation and perceptions of artificial intelligence (AI) applications among mathematics and science teachers in enhancing students' learning experience in mathematics classrooms. One prominent AI application this research seeks to explore, given its recent rise in popularity and usage, is ChatGPT. The study aims to…

Background: Content and Language Integrated Learning (CLIL) is a teaching methodology that integrates learning subject content with acquisition of proficiency in a foreign language (skills), developing both linguistic and conceptual competence. The approach aligns with the recommendations of the National Education Policy (NEP) 2020, which…

In Vietnamese secondary education, traditional science teaching that focuses on theory over practical application presents a challenge to developing students' scientific competence, a key priority of the national curriculum. Scientific competence is broadly defined as the ability to explain phenomena, conduct investigations, and apply knowledge in…

Nitrogen gas dominates the Earth's atmosphere but is largely ignored. Molecular nitrogen is extremely stable and so nitrogen is termed inert. What would happen if another 'inert' gas were the dominant species instead of molecular nitrogen? Here we show how unique nitrogen is and how important it has been to life on planet Earth.

Using the layout described here (which could be photocopied or handwritten), students can see how the periodic table was first envisaged after finding similarities in the properties of common elements. Then, with more discoveries some gaps were filled and, when additional elements did not fit, new groups had to be included.

The motion of a bead along a path restricted to straight lines (restricted brachistochrone), sliding without friction from rest and accelerated by gravity, is considered. For two shapes of path, the geometry of the route optimized to provide the least travel time from one point to another is obtained. The bead's travel times, path lengths, and…

This paper describes a very simple, but accurate method of finding the position of the infinity focus of a telescope objective relative to the rear face of its lens cell. The method is easily undertaken in the classroom and provides an opportunity for learners to conduct an interesting and novel optical experiment which introduces thick lens…

An easy operating tool has been developed for the quick measurement of thermoelectric power. The setup is made using a tweezer which consists of two circular copper plate electrodes. These copper electrodes are fixed to two arms of the tweezer which act as hot and cold probes. The setup has the very important advantage of easy sample mounting and…

Before reading this essay, go to your kitchen and find a bottle of Italian salad dressing. Get one that has been sitting still for a while at a fixed temperature--that is, one in thermal equilibrium. You will find an oil-rich layer at the top of the bottle and a vinegar-rich layer at the bottom (see Fig. 1). But think for a moment before spreading…

In this paper we are interested in the relationship between disciplinary knowledge and its representation. We carry out a social semiotic analysis of a central tool used in astronomy--the Hertzsprung-Russell (H-R) diagram--in order to highlight its disciplinary and pedagogical affordances. The H-R diagram that we know today combines many layers of…

Benchtop NMR spectrometers are now becoming more widely employed in university teaching laboratories. These low-field instruments are increasingly used in reaction monitoring and product purity applications. NMR spectra obtained using these spectrometers (40-80 MHz) tend to suffer from significant overlap of signals when compared to those obtained…

A popular physics legend holds that scissors can cut paper with a speed faster than light. Here this counter-intuitive myth is investigated theoretically using four simple examples of scissors. For simplicity, all cases will involve a static lower scissors blade that remains horizontal just under the paper. In the first case, the upper blade will…

Science communication and science education aim to expose citizens to scientific knowledge, which is increasingly becoming a prerequisite for effective participation in modern society. We aim to present a review of science communication and science education literature, for highlighting the need for and importance of narrowing the gap between the…
