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…

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…

The purpose of this study is to examine how and in what ways the dimensions of the nature of science are included in the 6th, 7th, and 8th grade science textbooks taught between 1926 and 2018 and to determine how these dimensions are represented in textbooks based on curricula shifts. In this study, a total of 24 textbooks allowed by the Ministry…

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…

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…

This paper catalogs previous articles in "American Biology Teacher" on various aspects of teaching about science misinformation and identifies which of the core concepts are addressed in each. A concise overview of relevant themes is provided, along with how the concepts align with the Next Generation Science Standards. This may serve as…

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…

Course-based undergraduate research experiences (CUREs) are being increasingly implemented to broaden the opportunities for undergraduate students to engage in authentic research across STEM disciplines including chemistry. The present review synthesizes the literature on chemistry CUREs, encompassing 68 articles published between 2016 and 2022…

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…

This study aims to make a thematic classification of possible misconceptions about solid friction by reviewing papers in the literature which include conceptual difficulties about friction; in this way, the study contributes to the literature. The study's scope was limited to the dry friction that occurs with the interaction of two solid objects,…

The goal of all reform documents in science education is to target scientific literacy. Toward that end, having students understand the nature of science (NOS) is a critical component. As it turns out, the development of NOS conceptions is a cognitive learning outcome. Therefore, an explicit approach needs to be promoted and emphasized in the…

This work presents a homemade multirole 3D-printed modular spectrometer(MPMS), which can be easily assembled like bricks and expanded with several modules to measure different types of spectra, such as UV-vis absorption, fluorescence emission, flame emission/absorption, glow discharge, and even Raman spectra. The spectrometer is designed to be…

This research is a systematic literature review study that aims to explore the evidence in publications that report on the types of misconceptions experienced by students in learning chemistry by providing types of students' chemical misconceptions based on levels and obtaining the correct formulation of misconceptions so that they can be used as…

This review presents an overview and analysis of the body of research on special relativity theory (SRT) education at the secondary and lower undergraduate level. There is currently a growing international interest in implementing SRT in pre-university education as an introduction to modern physics. For this reason, insights into learning…

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…
