Catalysis is not only one of the most crucial principles of Green Chemistry but also one of the most used industrial strategies to improve yields and to shift to more environmental-friendly processes. Due to the great importance of catalysis, we propose a laboratory activity related to heterogeneous catalysis courses (upper and undergraduate…

Educators at Mississippi State University developed an at-home, kitchen chemistry style laboratory to accompany the Survey of Organic Chemistry lecture course. The course featured 12 lab activities; eight hands-on experiences that focused primarily on important organic concepts including acid strength, extraction techniques, chromatographic…

In this work we focus on neurodiversity, a recently defined facet of diversity. Chemical education is in its early stages of recognizing the value that neurodiversity brings to the field. After an overview of current terminology, we discuss general challenges that neurodivergent students face in chemistry classes. To create an inclusive class…

Improvement in student performance from educational reforms has driven current calls for changes in curricular, instructional, and assessment practices in higher education. Less research has addressed the possibility of such reforms aiding in resolving the well-documented inequities in educational outcomes between sexes and races/ethnicities in…

This paper provides seven topics on sodium hydrogen carbonate (NaHCO[subscript 3]) and its ions for readers looking for familiar material phenomena to strengthen students' understanding of the chemical concepts of thermodynamics. The first concept is the ideal gas law, followed by the van't Hoff equation, Gibbs energy, pH change, chemical…

Introductory chemistry textbooks often present valence bond (VB) theory as useful, but incorrect and inferior to molecular orbital (MO) theory, citing the electronic structure of O[subscript 2] and electron delocalization as evidence. Even texts that initially present the two theories on equal footing use language that biases students toward the…

Colorful transitions of various acid-base indicators have been used to illustrate the concept of chemical equilibria, especially in spectrophotometric determination of the equilibrium constants or pKa values. To accommodate an online laboratory environment necessitated by the COVID-19 pandemic, this work employs color analyses from digital images…

We report on a distance learning experimental project for chemistry-major students on the synthesis of ethyl dodecanoate (C[subscript 11]CO[subscript 2]Et), a model for biodiesel, considering green chemistry principles. Thus, we employed a "recyclable acid catalyst" (an ionic liquid) and used chemometrics and microwave heating (MW) to…

At a key moment when education systems are moving towards the development of 21st-century skills at school, we propose to develop them with a series of enquiry activities connected to the real world on the subject of Chemistry in Compulsory Secondary Education. The four selected topics have practical aspects, as they are related to industrial…

This paper aims to explore (1) students' chemistry self-efficacy beliefs and metacognitive skills during problem solving in chemistry, (2) a potential significant difference of chemistry self-efficacy beliefs and levels of metacognitive skills in accordance with subject fields and, (3) the level of chemistry self-efficacy beliefs as a predictor of…

Radiochemistry faces a well-documented training and recruitment crisis. Older radiochemists are retiring, and fewer young people are studying radiochemistry. In turn, this is leading to a shortage in newly qualified radiochemists, as well as a loss of historical knowledge (as know-how is often not passed-on). Here, we analyzed the relevance of the…

Nuclear magnetic resonance (NMR) spectroscopy is the tool of choice for organic chemists to determine the molecular structure of organic molecules and, as a result, is a fundamental topic in the organic chemistry curriculum. A novel laboratory module has been developed to expand the scope of NMR spectroscopy beyond structure validation at the…

My dissertation research has been a quest to understand how to improve metacognition development in undergraduate chemistry education. The first step I took in this investigation was to speak with those with the largest influence on an undergraduate chemistry student's education: the instructors. I interviewed seventeen postsecondary chemistry…

Marine communities are experiencing rapid environmental changes including warming temperatures and ocean acidification (OA). For organisms within these communities, responses to ocean change are shaped by population- and community-level interactions which may modify their responses. This dissertation integrates experimental, field, and modeling…

We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…
