The present paper analyzes and discusses specific methodological aspects instrumental in promoting the teaching of Green Chemistry (GC); it examines proposals and teaching experience reports from 284 papers published in the "Journal of Chemical Education" (JChemEd), until 2019. Using Discursive Textual Analysis and drawing upon previous…

In this article, we describe a fully computational laboratory exercise that results in an increase of students' understanding of what quantum chemical geometry optimization calculations are doing to find minimum energy structures. This laboratory exercise was conducted several times over multiple years at a small private undergraduate institution,…

Video games and immersive, narrative experiences are often called upon to help students understand difficult scientific concepts, such as sense of scale. However, the development of educational video games requires expertise and, frequently, a sizable budget. Here, we report on the use of an interactive text-style video game, NanoAdventure, to…

Quantum dots are colloidal semiconductor nanocrystals that display size-dependent electronic and optical properties. These materials are a visual demonstration of a quantum-mechanical effect. Here we present a laboratory exercise for undergraduate/Bachelor students as an introduction to colloidal nanocrystals and quantum dots. The students…

In this paper, we present a concise and technique-heavy route to the synthesis of dimedone for a second-year organic chemistry curriculum. Our preparation of dimedone guides students through a Michael addition followed by a Dieckmann cyclization, basic ester hydrolysis, and thermal decarboxylation, while allowing time for mechanistic discussion…

Despite the growing importance of nanomaterials in numerous industries, most undergraduate chemistry students are unlikely to encounter characterization techniques common in the field during their education. Scanning electron microscopy (SEM) is a common technique for materials characterization widely used in careers chemistry students are likely…

A variety of strategies have been introduced to tackle the issue of laboratory safety in academic settings. These strategies include innovative educational tools as students transition from the classroom into the laboratory, the introduction of policies designed to protect the researchers in the laboratory environment, and the creation of teams of…

Embedding Course-based Undergraduate Research Experiences (CUREs) into chemistry curricula has become a best practice due to the overwhelming evidence that these experiences deepen students' content comprehension, improve students' problem-solving skills, and increase retention within the major. For these reasons, faculty are often encouraged to…

The synthesis of a [2]rotaxane through three- or five-component coupling reactions has been adapted to an organic chemistry experiment for upper-division students. The experimental procedure addresses the search for the most favorable reaction conditions for the synthesis of the interlocked compound, which is obtained in a yield of up to 71%.…

Chemistry is a systems science that deals with complex-dynamic systems and systems thinking is an essential aspect of chemical practices. Thus, a systems thinking approach is needed in chemistry education for meaningful learning of the subject matter. Despite this necessity, systems thinking has not received sufficient attention in chemistry…

A simple photometric device was built to measure the kinetics of the title reaction. The device consisted of a green light-emitting diode (centered at 520 nm), a sample vial, a photodiode, and an Arduino microcontroller board. These parts were mounted on a black poly(lactic acid) holder which was manufactured by utilizing three-dimensional…

pH buffers are used extensively in research and industry making them an important chemistry topic for students to learn. This qualitative study uses the phenomenographic method and a resource theoretical framework to provide the first insights into how students approach conceptual buffer problems. Three scaffolded buffer question sets were…

An understanding of basic organic chemical reactivity is key for many biosciences students. The reactivities of different carbonyl groups affect their function in many biomolecules. A practical class, the two-step synthesis of paracetamol, has been devised to illustrate the electrophilic reactivities of carbonyls, which was covered in the…

Active learning, a common practice in higher education, has been shown to promote higher order thinking and skills. Class discussions have been chosen to be the medium to incorporate active learning in schools' curriculum. However, the rate of class participation could be low for certain courses. Literature has shown that the fear of negative…

General chemistry is a gateway course that students from several STEM-related majors take at the beginning of their college careers. Faced with high attrition rates of students in STEM fields and even higher rates for groups minoritized due to gender and ethnicity/race, this study explored how a general chemistry course influenced students'…
