This study is a follow up to two earlier studies characterizing student real-time use of mechanistic arrows. In these previous studies, students were asked to predict a product by drawing a curved arrow mechanism using an interface that allowed recording and replay of student actions. In the present study two different student cohorts responded to…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

The amount of protein in complex matrices such as food products is an important characteristic, at both a nutritional and a pedagogical level. There are several methods available for protein quantification, from simple UV absorption to mass spectrometry. The most common are based on the interaction of the proteins with colored compounds followed…

The mercury beating heart is a classic demonstration to introduce redox reactions in the classroom. Here we report a new, safer demonstration: the Galinstan beating heart. Galinstan is a commercially available eutectic alloy composed of gallium (68.5%), indium (21.5%), and tin (10%) that has low toxicity. When an iron nail touches the Galinstan…

This article offers a concise account of the known science underpinning the greenhouse effect and global warming. The greenhouse effect is described at different levels of sophistication. It explains how greenhouse gases work and their relative contribution to warming. Climate models are introduced, as are climate sensitivity, feedback mechanisms…

Teaching symmetry point groups to introductory inorganic chemistry students is often complicated by the difficulties students face with mental manipulation of complex molecules. Additionally, most textbooks provide practice in the form of random two-dimensional molecules or figures of little significance. As an alternative, an assignment is…

The ability to reason with representations is pivotal for successful learning in Organic Chemistry and is closely linked to representational competence. Given the visual nature of this discipline, this comprises competency in extracting and processing relevant visual information. With regard to the resonance concept, proficiency in identifying…

Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

Since ancient times, man has prepared medicines and used them in healing practices. Therefore, there has always been a great interest in the part of people in general and students in particular about medicines. The "Medicines, the Haute Couture of Pharmacy" summer camp has the objective to promote and improve the literacy in medicines…

Organic chemistry is challenging for novices as it involves a large quantity of organic reactions. Effective learning requires not only profound theoretical knowledge but also the ability to reason about causal mechanisms. This study investigated pre-service chemistry teachers' mechanistic reasoning and the implicit cognitive process. Participants…

My thesis work is focused on conceptual and epistemic learning and characterizing the environments in which this learning takes place. Earlier studies conducted by the Stowe group explored how instructional practices, instructional emphasis, and assessment emphasis relate to student outcomes in general and organic chemistry courses. Student…

Education in organic chemistry is highly reliant on molecular representations. Students abstract information from representations to make sense of submicroscopic interactions. This study investigates relationships between differing representations: bond-line structures, ball-and-stick, or electrostatic potential maps (EPMs), and predicting partial…

In virtual laboratories, various cognitive aids are used to improve students' performance and assist them while completing experimental tasks. However, excessive use of cognitive aids in virtual laboratories can lead to a cognitive load on students which affects their performance. In this paper, we proposed the concept of adaptive aids virtual…

Machine learning (ML) is extensively applied in chemistry, particularly in vibrational spectroscopy. However, few teaching examples effectively demonstrate the capabilities of ML in classifying polymeric materials, exhibiting subtle spectral differences that elude visual discrimination. This study presents a teaching example specifically tailored…

This study investigates alternative conceptions of chemistry concepts among Faculty of Science students at Palestine Technical University-Kadoorie. Students are found to have incorrect views about fundamental chemistry concepts. The study aims to identify these misconceptions, understand their origins, and their impact on students' comprehension.…
