The COVID-19 pandemic disrupted teaching and learning worldwide during the Spring 2020 semester. Students and teachers had to shift to online teaching and learning in short order. With little time to prepare and inadequate training, faculty and students were thrust into a fluid situation, receiving training while teaching and learning. This essay…

In this communication the development of an online course on the topic "organic chemistry" for nonmajor chemistry students is described and discussed. For this online course, the existing classroom course was further developed. New elements such as podcasts, task navigators, and a forum for discussing the solving of tasks or problems…

General chemistry, CHE 101, at Hampton University is an undergraduate course designed to meet curriculum requirements for nonscience majors. The four-credit course consists of a lecture and a laboratory, taken concurrently. The lecture consists of three 50 minute or two 75 minute sessions, and the laboratory consists of one 3 hour session every…

Readily available, free, computational approaches, adaptable for topics accessible for first to senior year classes and individual research projects, emphasizing contributions of noncovalent interactions to structure, binding and catalysis were used to teach Course-based Undergraduate Research Experiences that fulfil generally accepted main CURE…

Reaction mechanisms commonly used in organic chemistry are a great challenge for students in terms of understanding the representation and inferring the appropriate chemical concepts. In order to support the process of identifying and selecting chemical concepts, purposefully designed case comparisons are widely used. While these tasks place great…

A common misconception about dissolving is that heating and/or stirring are required for the dissolving process to occur. In this study, quantitative experimental evidence was collected and analyzed to demonstrate that neither heating nor stirring is required for dissolving. Educators can use the data and results in this study to address this…

We report a series of experiments based upon cinnamon oil that were developed to provide a practical integration of green and sustainable chemistry concepts for the organic chemistry laboratory. Five experiments centering around cinnamaldehyde as a green, plant-based chemical were performed by undergraduate students in a second-year organic…

The ability to visualize chemical processes can be an asset in a teaching laboratory. Despite the advances in laboratory technology, apparatuses used in the teaching of simple thermodynamics concepts, such as exothermic/endothermic reactions, historically remain unchanged and can benefit from a fresh perspective. The recent incorporation of…

This paper revisits the tie-dyeing process through a bioinspired and safer alternative to nucleophilic aromatic substitution (S[subscript N]Ar) reactions for an introductory organic chemistry laboratory. The simple and straightforward experiment provides students with an opportunity to gain practical experience in conducting a chemical reaction in…

In the spring of 2018 the Northern California/Nevada Section of the American Association of Physics Teachers was alerted to a local high school's plans to eliminate physics for the following school year. As part of the campaign to support the school's efforts to sustain physics in the following year, the physics offerings from the surrounding…

We describe a paper-based microfluidic device for iron(III) assay in an applied instrumental analysis laboratory. Simple and convenient devices were fabricated by the students using patterning of filter paper to investigate three different procedures: drawing a boundary with eyeliner or wax pen; drawing a boundary with waterproof permanent marker…

A set of visualizations developed for the purpose of explaining solid state lattice structures is presented in this paper. The visualizations provide students with the option to view stacking patterns, extended structures, and individual unit cells for simple, body-centered and face-centered cubic, and hexagonal close-packed structures.…

Studies on teacher education have given increasing attention to pedagogical content knowledge (PCK): the knowledge necessary for teaching specific content as a theoretical construct. As a component of the teacher's professional knowledge base, orientations toward teaching science (OTS) are critical to developing the PCK needed for inquiry-based…

A bachelor's degree program in chemistry typically starts with basic concepts in mathematics, physics, and chemistry. Those principles are very important because they pave the ground for future advanced studies and, therefore, one needs to present them in a clear but rigorous way. One example is provided by the mathematical notion of an iterative…

The National Survey of Science and Mathematics Education (NSSME) has provided periodic snapshots of K-12 science instruction in the United States for over 40 years. Study topics include teacher background and beliefs, professional learning opportunities, course offerings, instructional objectives and activities, resources for instruction, and…
