This article aims to analyze the potential of new technologies in the area of green chemistry didactics. When viewed through the lens of systems thinking, the use of these ubiquitous tools can be a driving force for the development of a sustainable world because of their global use and reach. The authors concentrate on flat e-learning platforms,…

To develop expertise, novice chemistry students require deliberate practice with immediate and thoughtful feedback. Whereas opportunities for practice are often abundant, opportunities for feedback tend to be much scarcer. To address this challenge, we collaborated with students to develop a flexible and scalable online platform called…

Selecting less hazardous chemicals is a core tenet of green chemistry but is difficult to teach in practice. The upper-year undergraduate or graduate level exercise described here empowers students to make such decisions themselves. Students are tasked with finding the greenest chemical for a specific purpose described in a hypothetical scenario,…

As the World Health Organization declared COVID-19 a global pandemic in March 2020, universities around the world reacted quickly by shifting classes online. To varying extents, this rapid change required chemistry teacher educators to rethink and redesign their units and delivery. Some teacher educators may have perceived this shift as a timely…

The RRKM Theory of Unimolecular Reactions and Marcus Theory of Electron Transfer are here briefly discussed in a historical perspective. In the final section, after a general discussion on the educational usefulness of teaching chemistry in a historical framework, hints are given on how some characteristics of Marcus' work could be introduced in…

An effective guided inquiry forensic case study (a pharmacy break-in) is described for first-year students. Four robust introductory forensic chemistry and biology experiments are used to analyze potential drug samples and determine the identity of a possible suspect. Students perform presumptive tests for blood on a "point of entry…

A hands-on approach to introduce the chemical elements and the atomic structure to elementary/middle school students is described. The proposed classroom activity presents Bohr models of atoms using common and inexpensive materials, such as nested plastic balls, colored modeling clay, and small-sized pasta (or small plastic beads).

The challenge in chemistry courses for nonscience majors (such as nursing majors) is not that the students cannot learn chemistry but that they "think" they cannot learn chemistry. With this in mind, the authors' goal was to create a learning environment in which students would feel motivated to learn and would gain confidence in their…

A number of concerns have been raised by researchers regarding the use of models in science classrooms. Those concerns have largely been raised in studies involving interviews with students and teachers. In this article, I address issues that surfaced through my examination of classroom teaching episodes; two of these episodes and their associated…
