This study explores the ontological perspective in analyzing students' problem-solving related to mechanical energy conservation. The research involves 18 high school students whose explanations were qualitatively analyzed using an extended ontological framework. Initially, students predominantly employed matter-based predicates and…

We use new survey data from 1,203 households in rural Eastern India to estimate cross-sectional models of overall energy use and embedded emissions. Findings indicate that the primary driver of household energy use is household size and affluence. This is unsurprising and consistent with findings from the engineering literature on energy demand.…

What if you could challenge your fourth graders to create a minimally invasive, highly efficient dam? With this volume in the "STEM Road Map Curriculum Series," you can! "Hydropower Efficiency" outlines a journey that will steer your students toward authentic problem solving while grounding them in integrated STEM disciplines.…

Measuring innovation is key to realizing innovation in practice. One of the primary reasons why measurement is important stems from the fundamental principle that what is measured is, in turn, what garners attention and action. Systematic measurement of innovation can enable researchers and practitioners to propose and undertake strategic…

Metal-air battery technology is a promising new energy storage solution in the green energy economy but also an excellent tool to educate students on the working principles of batteries. A simple yet powerful construction of a metal-air battery is shown, which consists of a plastic mint box, a cathode, an anode, and an electrolyte. Furthermore,…

Energy conversion devices such as fuel cells, metal-air batteries, and electrolyzers have been envisaged as possible solutions for cutting down the continuous accumulation of greenhouse gases resulting from the combustion of fossil fuel. The bottleneck reaction for these devices is the oxygen reduction reaction (ORR) occurring at the cathode. The…

In this study, which focuses on selecting the material and predicting its mechanical behaviors in materials science, an Artificial Neural Network (ANN) was used to predict and simulate the low-speed impact effects of hybrid nano-doped aramid composites. There are not enough studies about open education practices in this field. Since error values…

Renewable energy is a global concern and should be incorporated into education to raise awareness among younger generations, including in physics education. Educators have made various efforts to raise awareness of the importance of pursuing renewable energy. A breakthrough sought in this research is to incorporate collaborative learning into the…

In this research, an educational approach to the concept of energy is proposed. It is based on the history of physics. In 1854 Hermann Hemlholtz gave a popular lecture on the recent discovery that energy is conserved. Such lecture is used as a guide to introduce the pupils within several nuances of this concept. Not much mathematics is used, so…

Purpose: The purpose of this paper is to present a comprehensive analysis of the carbon footprint of the Delft University of Technology (TU Delft), including direct and indirect emissions from utilities, logistics and purchases, as well as a discussion about the commonly used method. Emissions are presented in three scopes (scope 1 reports direct…

Green internet of things is important to achieve atmospheric decarbonisation, it is crucial to implement procedures and practices that prioritise resource conservation and environmental protection. However, the growing use of internet of things devices poses a challenge due to their high-energy requirements for data reception and transmission…

The research aimed to describe the development of solar electric cars as a prop in energy conversion learning using the analyze, design, develop, implement, and evaluate (ADDIE) model and to ascertain the effectiveness of an electric car as a prop in energy conversion learning. Utilization of prop in the learning process is one way to support the…

This study aims to understand middle and high school students' ecosystem knowledge including knowledge about the food web, food pyramid, and energy flow. The data were collected from 250 middle school and high school students. Students' drawings were used to collect data and coded as correct, wrong, or no answer. Then, students' wrong answers were…

The concepts of electronegativity and classical electronegativity scales are briefly described. Electronegativity scales have practical quantitative applications, and this work suggests activities which can assist students select the scales for use in chemistry applications. It provided examples of the use of an appropriate electronegativity…

Loadshedding, the scheduled power outage implemented in South Africa, has significantly affected various sectors, including higher education institutions. This article explores the impact of loadshedding on students in a South African university, focusing on the difficulties they face, and the coping strategies employed. The study adopts a mixed…
