Earthbound manifestations of gravity in falling objects are distorted by the large mass and size of the Earth. Movement is also affected by air resistance. This article questions whether an approach based on everyday observations is necessarily the best starting point for introducing the idea of Newtonian gravity. Instead, a theoretical approach…

Eigenstates of a quantum mechanical system reflect one to one correspondence with energy level. However, in some systems more than one or a group of eigenstates correspond to a single eigenvalue. To introduce more than one eigenstate corresponding to single energy eigenvalue in 1D-harmonic oscillator, we introduce a new perturbation term and find…

The purpose of this article is to outline some activities using resources that can generally be found in most kitchens and involve very little expense. It is based upon a workshop at the 2019 International Primary Science Education Conference (PSEC) in Edinburgh, which consisted of a wide variety of demonstrations of science in action, where…

Understanding the development and structure of people's concepts of national groups can contribute to an understanding of their behavior in the political arena, including perhaps the recent rise in nationalism and anti-immigrant sentiment. Here, we provide a developmental investigation of concepts of national groups in a sample of 5- to 8-year-old…

This current study explored twelfth-grade students' conceptions regarding electrochemistry in the Ximhungwe circuit of the Bohlabela district in the Mpumalanga province of South Africa. The sequential explanatory design was used to gather and analyse quantitative data first before gathering and analysing qualitative data for the current study. In…

Professor Gordon argues for a significant reorientation in the focus and impact of assessment in education. For the types of assessment activities that he advocates to prosper and positively impact education, serious attention must be paid to two important topics: (1) the conceptual underpinnings of the assessment practices we develop and use to…

In multielectron atoms or molecules, quantized electronic energy states known as term states provide a framework for interpreting absorption and emission spectra. Enumerating the term states associated with any particular electron configuration is possible using time-honored procedures, but the underpinnings of the methods do not always receive…

Physics is directly related to various professions since it is a fundamental science. Opticianry is one of such physics related professions. In this study, it was aimed to determine the conceptual understanding levels of opticians related to the concepts of light and optics which are directly related to their professions. In the study, which was…

What are the structural characteristics of written scientific explanations that make them good? This is often difficult to measure. One approach to describing and analyzing structures is to employ network theory. With this research, we aim to describe the elementary structure of written explanations, their qualities, and the differences between…

The notion or expectation of simplifying final mathematical results remains problematic in that it is ill-defined, tied more closely to algorithmic versus conceptual understanding, and decontextualized from the content, purpose, and application of the mathematics in question. In this article, the authors advocate for a tool-focused view of…

This study offers a comprehensive investigation of 14-15-year-old students' comprehension of non-Euclidean geometries, with a specific focus on the assessment of their understanding through a 15-itemed test. The primary objective of this research is to assess the current state of students' knowledge and proficiency in non-Euclidean geometries and…

This extensively updated teaching resource provides over 100 engaging, full-color visuals with explanations of how they can be used to stimulate mathematics learning, to explain mathematical concepts, and to assess students' mathematical understanding in grades K--8. Readers are provided with a strong mathematical background, downloadable copies…

Background/purpose: Although mathematical representation ability is a significant ability and an interesting topic to study, quite a few researchers have studied this ability, and even fewer have examined it through the implementation of epistemic learning patterns based on problem-solving. In fact, this learning pattern is epistemic and makes…

This study aims to determine the misconceptions of teacher candidates about the greenhouse effect concept by using Artificial Intelligence (AI) algorithm instead of human experts. The Knowledge Discovery from Data (KDD) process model was preferred in the study where the Analyse, Design, Develop, Implement, Evaluate (ADDIE) instructional design…

This research investigated how freshman students' epistemological beliefs in physics are impacted by gender and academic performance in a general physics course. Data were collected from 1220 university freshman students from 22 different programs in Türkiye. In this causal-comparative research, the well-known Colorado Learning Attitudes about…
