Entropy and the second law of thermodynamics have long been identified as difficult concepts to teach in the physical chemistry curriculum. Their highly abstract nature, mathematical complexity and emergent nature underscore the necessity to better link classical thermodynamics and statistical thermodynamics. The objectives of this systematic…

The purpose of this study is to "meta"-analytically evaluate research that used chemical bonding-based interventions to improve academic performance. Through "meta"-analysis, the present study used several keyword patterns (e.g., chemical bonding, experimental, chemistry education, science education) via relevant databases…

In basic education in Brazil, there is often confusion concerning the relationship between the greenhouse effect and global warming. The present work evaluates the status of research on this issue. A systematic literature review (SLR) was undertaken, considering studies published between 2013 and 2024, obtained using the databases CAPES Journal…

A systematic review of Threshold Concepts provides a thorough and structured analysis of the existing literature related to these essential and transforming concepts in education. Threshold Concepts represent ideas or knowledge that, once understood, allow the student to access deeper levels of understanding of a discipline. These concepts are…

Representation plays an important role in helping students understand chemistry learning. This is due to the many chemical concepts that require visualization. Representation is something that still needs to be studied. So this study aims to see the development of representation research in chemistry education. The articles used in this study are…

We review the literature, from 2006 to 2020, focused on the teaching and learning of chemical bonding. The studies included in our review (48 studies set in 19 different countries overall) involved secondary and postsecondary students as well as K-12 teachers and university faculty. We synthesize these studies' findings to provide implications for…

There is a prevalent consensus among science education scholars that teaching socioscientific issues (SSI) has notable importance for promoting functional scientific literacy and raising responsible citizens. However, teachers encounter numerous problems when teaching SSI, so they may not prefer to teach them. Today, we still do not know many…

Learning progressions (LPs) are descriptions of successively more sophisticated ways of thinking about an idea over an extended period of time. The growing interest of researchers in learning progressions is grounded in the potential it holds to align curriculum, instruction, and assessment. Previous review of research on LPs by Duschl et al.…

The purpose of this study is to review the postgraduate theses on science/physics education in Turkey to guide the teaching of the sound concept. Although the theses examined within the scope of this study belong to a certain region, the previous literature shows us that the learning difficulties/misconceptions are generally independent of…

Many studies have characterized students' difficulties in understanding and reasoning about scientific mechanisms. Some of those studies have drawn implications on teaching mechanisms and how to guide students while reasoning mechanistically. In this theoretical article, I claim that one component that has not garnered much attention in the…

This paper presents a perspective of how the radiation and radioactivity themes have been discussed at the high school level in several locations around the world. In this context, scientific journals, academic journals, theses, dissertations, and media materials were analyzed. Recent research has shown that the concern with the discussion about…

The theoretical framework and conceptual framework help to determine the purpose of scientific research, facilitate the analysis of data, organize the thoughts of researchers, increase the reliability of research, and ensure that research is shared in a wide area. Although these two concepts seem to be basically the same, they have structural…

Of the many disciplines that rely on calculus, physics is among those with the strongest connections to this branch of mathematics. For instance, the derivative--one of the key notions of calculus--is used to describe velocity and acceleration, which play a central role in mechanics. In post-secondary education, in particular at the college level,…

New reforms in science education call for three-dimensional learning by integrating disciplinary core ideas, science and engineering practices, and "crosscutting concepts" (CCCs). These reforms defined the new term, crosscutting concept (CCC), as a lens that has explanatory power across disciplines. To describe how researchers are…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…
