The Hofmeister series is a recurring trend that ranks ions' abilities to influence various aqueous processes in solution. Herein, a set of project-based experiments was developed for students in an upper-level physical chemistry laboratory to investigate the specific ion effects on the thermodynamics of caffeine partitioning between aqueous and…

Assessments in tertiary science subjects typically assess content knowledge, and there is current need to both develop and assess different forms of knowledge and skills, such as communications and digital literacies. A digital explanation is a multimodal artefact created by students to explain science to a specified audience, which is an…

There is a growing need for workers with STEM-aligned training in the modern global economy, but a paucity of workers to fill these positions. One important contributor to this issue is low student persistence in STEM. Nontraditional science courses that utilize more active-participation and learning are attractive as tools to increase student…

We conducted a study with introductory and upper-division level physics students in a Mexican and a Spanish university to learn how students recognize the main characteristics of the electric field in three of its more widely used representations, namely, algebraic notation, vector field plot, and electric field lines, and how the students do…

This article reports on the introduction of a simple, portable, low-cost, and hands-on spectral tool for first-year chemistry students to use inside the laboratory and its spontaneous dissemination outside of the laboratory. The Mini Spec is a refinement of the Schwabacher minispectroscope in terms of simplicity and language load on the students.…

E-learning platforms and processes face several challenges, among which is the idea of personalizing the e-learning experience and to keep students motivated and engaged. This work is part of a larger study that aims to tackle these two challenges using a variety of machine learning techniques. To that end, this paper proposes the use of k-means…

A discovery-based undergraduate organic chemistry lab experiment has been developed in which students establish the diastereoselectivity of hydride reduction of the a-chiral ketone (±)-benzoin isopropyl ether to erythro and threo diastereomeric alcohols by two different reducing agents. Students achieve this goal by working collaboratively and…

In March 2020, over the course of less than 2 days, the author's university went from business as usual to suspending classes until weeks later and then completing the semester online. The author reflects on the changes to the mode of teaching, use of technology, problems with academic integrity, and class engagement. The most problematic issues…

The COVID-19 pandemic presented numerous challenges for all levels of the education system. In March 2020, virtually all colleges and universities in the United States moved all instruction to an online environment as a result of the pandemic. While this posed challenges for all faculty, it posed a particular challenge for those faculty members…

Educators around the world have been challenged to adapt their teaching and pastoral care rapidly in response to the coronavirus pandemic. In this article, we, the academic members of the Chemistry Education and Communication Research Theme (CECR) from the School of Chemistry at the University of Sydney, reflect on the challenges and successes…

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…

Owing to the COVID-19 global pandemic, three chemistry instructors at Ferris State University, with no previous online instructional experience, made the abrupt midsemester switch from face-to-face to remote delivery in their respective chemistry courses. This paper discusses the importance of communication during the rapid change to remote…

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…

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…
