Colorimetry allows every color to be defined as a combination of three values, known as "color coordinates." Color coordinates allow researchers to universalize and standardize their color measurements, and nowadays, determining the color coordinates of samples is a routine method applied by organic and analytical chemists, students, and…

Three-dimensional printing was used to prepare a p-bonding model with embedded magnets. The model enables students to have a kinesthetic experience that simulates the energetics of bonding, antibonding, and nonbonding p-orbital interactions.

In this essay, findings from research in science and chemistry education are used to describe and discuss progression in students' structure-property reasoning through schooling. This work provides insights into the challenges that students face to master this important component of chemical thinking. The analysis reveals that student reasoning is…

A 4-week mini-project is proposed for an experimental Physical Chemistry course applied in Food Science training. Activities include preparation of beet extract for the extraction of betanins and analysis of the kinetics of betanins in thermal degradation at three temperatures (60, 70, and 80 ºC). In addition to developing common laboratory…

A green, aza-Michael reaction is described that can be used to teach undergraduate students conjugate addition of nitrogen nucleophile to an a,ß-unsaturated ester. Students analyze spectral data of the product obtained from the assigned reaction to determine product structure and propose the mechanism of its formation. The experiment requires…

General chemistry courses predominantly use expository experiments that shape student expectations of what a laboratory activity entails. Shifting within a semester to course-based undergraduate research activities that include greater decision-making, collaborative work, and "messy" real-world data necessitates a change in student…

The topic of chemistry safety was included at the margins of traditional chemistry education in China. In order to understand the concerns of the safety issues based on the new chemistry curriculum in the mainland China secondary school, this study analyzed old and new secondary chemistry curriculum standards via the Natural Language Processing…

Science education is facing a challenge of students who are losing interest in learning science subjects including chemistry. This research provides a review of literature that emphasizes on the factors affecting secondary school students' attitudes toward chemistry. Thirty-six studies were selected in Google scholar and ERIC database in the time…

The initial period of young teachers' careers is always significant in developing their professional capability. This is when teachers start coming into contact with practical teaching, which is more diversified than the theoretical training at the University. In this research, the authors propose a process of combining the Lesson Study model with…

The importance of chemistry practical work in enhancing students' performance and 21st-century skills has been highlighted in the literature. However, Malaysian Matriculation chemistry lecturers were lack of knowledge in the 21st-century pedagogies and practiced the cook-book recipe teaching style which proved ineffective in enhancing students'…

This study was conducted to determine the differences in the conceptual understanding of 52 Turkish students who were taught with a scientific argumentation approach in grade 12 chemistry. The concept test was administered to the participants as a pre-test and post-test, and it contained two questions. The first had two sub-questions had two…

Teaching laboratories are designed to educate students on basic theories and techniques through guided laboratory experiments. As advances in automation revolutionize research chemistry laboratories, teaching tools can advance to reflect these changes. In this study, we integrated several programmable instruments, including automated pumps for…

Educational Scaffolding was first mentioned in 1976 by Wood et al. Several examples for scaffolding in chemistry are also known from the literature. As written scaffolds, stepped supporting tools to support students while solving problems in organic chemistry were developed, applied, and evaluated. Although the students rated the tool as very…

In this study, adults naïve to organic chemistry drew stereoisomers of molecules and explained their drawings. From these explanations, we identified nine strategies that participants expressed during those explanations. Five of the nine strategies referred to properties of the molecule that were explanatorily "irrelevant" to solving the…

Visuospatial thinking is considered crucial for understanding of three-dimensional spatial concepts in STEM disciplines. Despite their importance, little is known about the underlying cognitive processing required to spatially reason and the varied strategies students may employ to solve visuospatial problems. This study seeks to identify and…
