Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

Biochemistry students at the introductory level easily comprehend the importance of energy-yielding oxidation and reduction biochemical processes, but nevertheless, they fight with words "oxidation" and "reduction" (and with the corresponding adjectives, "oxidized" and "reduced") applied in biochemistry…

How anthropomorphic reasoning functions in scientific thinking has been a controversial topic. There is evidence it is problematic as well as evidence it can play productive roles, for scientists and for students. In science education, however, the prevailing view remains that it is an impediment. For this study, we have chosen examples of what we…

This article aims to simplify and facilitate the process of practical teaching of enzyme kinetics by utilizing minimal teaching laboratory requirements. Simultaneously, it ensures that students comprehend the enzyme kinetics experiment effectively. The focus is on teaching students how to estimate the maximum velocity (Vmax) and Michaelis constant…

An activity is described that uses simple materials and an easy-to-perform protocol to estimate the Curie temperature of nickel, which is the temperature at which nickel loses its ferromagnetism. To do so, an object made of nickel metal is heated with a lighter until it loses its ferromagnetism. The metal is allowed to drop into a beaker that…

We discuss how research on student difficulties was used as a guide to develop, validate, and evaluate a Quantum Interactive Learning Tutorial (QuILT) to help students learn how to determine the completely symmetric bosonic or completely antisymmetric fermionic wave function and be able to compare and contrast them from the case when the particles…

Atomic-level visualizations serve as pivotal instructional tools in chemistry education, providing insights into the particulate level of matter, a dimension fundamental, yet typically invisible, in the study of chemistry. This research investigates how students' engagement with these visualizations influences their conceptual understanding of…

Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I, reintroduced in Organic Chemistry I, and then utilized throughout other higher-level chemistry courses. A molecule or ion can be said to exhibit resonance when it can be represented by two or more chemical structures (i.e., Lewis structures) that…

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…

This study explores science teachers' questions encouraging students to see and speak about natural phenomena in novel ways. In particular, the teachers' challenging questions that may be instrumental in persuading students to see and talk about everyday events differently were qualitatively examined. The participants were 22 science teachers.…

Achieving knowledge integration for deep learning requires students to construct well-connected knowledge structures by understanding and applying the central ideas of a concept. However, research on student learning in work and mechanical energy reveals persistent challenges in grasping fundamental concepts, particularly in connecting the…

Energy is one important concept in physics, but science education research has repeatedly shown that students struggle to develop a full understanding of energy. Especially challenging for students is the notion of potential energy. Overwhelmed by the sheer number of potential energy forms, students struggle to make connections between them.…

Teacher-centered lecture-style classes predominate in the Republic of Korea. Typically, classes follow a three-stage structure: introduction, development, and wrap-up. This study aims to analyze concepts teachers present in each stage of photosynthesis classes from a conceptual perspective and how these concepts are connected across each stage. To…

Dimensional analysis is an algorithm currently in use in almost every chemistry classroom in the United States. Chemistry educators use this procedural tool in the classroom with the intention of providing students with a reliable method to solve many of the relatively simple math problems they encounter. The unintended consequence of using this…
