A systematic literature review across multiple scientific disciplines was conducted to explore students' understanding of atomic structure, focusing on students' ACs. A total of 112 publications between 1972 and 2023 were selected for the study. Within the selected body of literature, 851 instances of ACs were distributed across students ranging…

Although researchers have extensively studied student conceptions of radioactivity, the conceptions held by preservice teachers on this subject are largely absent from the literature. We conducted a qualitative content analysis of problem-centered interviews with preservice teachers (N=13) to establish which conceptions are held by preservice…

Chemistry students should learn not only the key concepts and processes of the discipline but also how they arise, are established, and develop over time. Undergraduate programs for chemistry teachers seldom include training in the history of chemistry to prepare future teachers to put concepts in a historical context. In schools, atom and atomic…

The present technology report is aimed at demonstrating how the implementation of VR chemistry simulations of atomic structure enhances learning among students. MEL Chemistry VR lessons were incorporated into the classroom for 43 first-year undergraduate ITMO University students. The visualization techniques provided the learners with two…

As part of their third-year general chemistry program, students at the University of the Côte d'Azur are taught the basics of radioactivity. The view that third-year university students have of the periodic Table of the Elements is often reduced because it ignores the vast majority of isotopes. As part of this program, a practicum devoted to the…

Simulation of physics phenomena is an indispensable part of experimental studies. Undergraduate and postgraduate physics students are often introduced to the simulation of various phenomena as one of the most important pedagogical tools. In this document, we demonstrate the simulations of the two-body decay of a particle and equilibrium states in…

It could be argued that the main goal of the teaching process is to create accurate projections of scientific models in the minds of individuals. In this context, it could be argued that it is important to determine the change and development of the mental models that individuals create for events/phenomena and related metaphors in this process.…

One of the main topics of elementary physics is the idea that every material is composed of "little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one other." These particles could be atoms or molecules. Atoms are the smallest part into…

A number of useful and interesting exercises regarding nucleus and nuclear fission are performed to make these concepts more understandable to high school or even college students.

Many compounds can be represented well in terms of the two-center-two-electron (2c-2e) bond model. However, it is well-known that this approach has limitations; for example, certain compounds require the use of three-center-two-electron (3c-2e) bonds to provide an adequate description of the bonding. Although a classic example of a compound that…

[This paper is part of the Focused Collection in Investigating and Improving Quantum Education through Research.] The modern physics course is a crucial gateway for physics majors as it provides an introduction to concepts beyond the scope of the K-12 education. This study collected 167 modern physics syllabi from 127 U.S. research-intensive…

It is essential for introductory level chemistry students to understand atomic models and how atoms interact to form chemical bonds. The tactile model in this article utilizes marbles to represent subatomic particles, a cup to represent the nucleus and wooden rings to simulate the electron orbitals. These inexpensive items can be combined to…

In Japan, research activities by junior and senior high school students show an upward trend. However, there are limited examples of research activities in the field of elementary particles and atoms. This is due to the difficulty associated with procuring research tools such as accelerators or particle detectors. Therefore, we hosted the 'Accel…

This paper presents the design and reports on the use of a simple and inexpensive cloud chamber kit that is compatible with active learning, experiential learning, and project-based learning strategies. The kit was developed for use in a first-year undergraduate nuclear science seminar class at a university in the US. Diffusion cloud chambers are…

The purpose of this study is to investigate physicists' views about the possible impacts of recent developments in quantum physics on educational implementations, particularly on science learning. Throughout the research a mixed-methods strategy was used. The data were collected from the physicists working at the European Organization for Nuclear…
