The integration of web-based discussion platforms in education is increasingly recognized for its potential to enhance pedagogical practices. This study examined the impact of web-based discussion tools on teachers' pedagogical practices in teaching organic chemistry in selected Rwandan secondary schools. The study adopted sequential explanatory…

The [2 + 2] photocycloaddition reaction of olefins is an effective, atom-economical approach to produce cyclobutane compounds in organic synthetic chemistry, and they usually exhibit high regioselectivity and stereoselectivity. Here we devised a solid-state [2 + 2] photocycloaddition experiment that introduces senior undergraduate students with…

In all fields of chemistry, it has become essential to use quantum chemical calculations and machine learning for explaining and predicting chemical phenomena. However, it is challenging to apply textbook knowledge to practical research. In this study, we developed teaching material based on computational chemistry to promote the integration of…

Active engagement is critical to student success in Organic Chemistry. In this paper, I trace the trajectory of student engagement in an introductory organic chemistry lecture series over the course of the COVID-19 pandemic. I detail my approach to cultivating student engagement in an online environment, evaluate the success of these approaches…

Organic chemistry is notorious for being difficult to learn. Herein we describe a two-pronged approach to engage students in the ability to afford successful knowledge building. We have drawn on focus group interviews with students to show that the approach is appreciated by the students. The two prongs comprise peer learning in small groups and…

The benzoin condensation of benzaldehyde is a staple of the undergraduate organic chemistry laboratory, introducing the current topic of nucleophilic carbene organocatalysis. Our procedure makes notable improvements to current practice, including the elimination of solvent waste and an "18-fold reduction of reaction time." We have…

3D printers have facilitated a wealth of 3D printed molecular models illustrating key structural concepts for student learning. However, general adoption of 3D printed models in the organic chemistry classroom proceeds slowly as the majority of consumer-grade 3D (fused deposition modeling (FDM) and resin) printers are inherently monochromatic,…

The practical two-step synthesis of 1-phenylthiourea is reported here as an undergraduate experiment for the organic synthesis laboratory. The reactions involved in 1-phenylthiourea preparation are very useful didactic examples to illustrate concepts relating to carbonyl substitution and addition, the effect of pH on solubility of organic…

A one-pot regio- and stereoselective synthesis of a dipyrromethane and a bis(indolyl)methane based on two consecutive reactions of nitrosoalkenes with pyrrole or indole, respectively, is described as an experiment to be carried out by upper-division undergraduate students in a laboratory classroom. Importantly, the ability of electrophilic…

This commentary provides an overview of abduction, also known as Inference to the Best Explanation, and argues that the term and relevant problem-solving methods should be adopted by chemistry educators. Abductive reasoning, especially within the context of science and medicine, continues to be an active area of exploration for philosophers and…

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…

There has been dramatic growth in interest and research regarding organic photochromism in recent decades. Despite this, the topic is seldom addressed in the undergraduate chemistry curriculum. Herein, we present a straightforward and robust experiment for the second semester organic chemistry laboratory curriculum which combines multistep…

A fast, operationally simple, and reproducible synthetic protocol for anthraquinone dyes (AQDs), suitable for upper-division undergraduate industrial and organic chemistry laboratory courses, has been developed. This experiment is composed of three stages; the first step deals with the synthesis of AQDs, followed by a purification step, and…

At the molecular level, chemical processes involve the rearrangement of atoms in space and time. Students often struggle with visualizing the 3D spatial characteristics of molecules and transition states, as well as recognizing the dynamic nature of chemistry. Both visual spatial skills and representational competence should be explicitly trained…

Many disciplines have used concept inventories (CI) to better understand the alternative ideas held by students. Administering a CI at both the beginning and the end of the semester can yield much information. For example, a comparison of both pre- and post-test responses can help determine if specific gains in student learning were met. In this…
