An understanding of buffers is important in a variety of chemistry subdisciplines, with relevant applications to the life sciences and health profession-related fields. Here, we describe the development and implementation of a lab that involves creating a buffer solution using baby wipes and deionized water. The goal of this lab was to emphasize a…

The students in our physical chemistry course pointed out an interesting trend in the bond dissociation energies (BDEs) of successive homolytic cleavages of hydrogens from methane and water. Namely, while there is an increase in BDE from CH[subscript 4] to CH[subscript 3], there is a decrease in BDE from H[subscript 2]O to OH. In order to explain…

Preceding even the Hartree-Fock method, molecular integrals are the very foundation upon which quantum chemical molecular modeling depends. Discussions of molecular integrals are normally found only in advanced and technical texts or articles. The objective of the present article is to provide less experienced readers, or students in a…

Due to the wide and the ever-increasing strategic applications of quantum chemistry in chemical industries, it is important to introduce chemical engineering students to illustrative case studies that deploy molecular modeling in the design of reactors and derivation of thermochemical functions. Herein, we demonstrate how quantum chemical…

The objective of this examination was to determine if there were significant differences in reported levels of motivation across five teaching tasks, as well as time allocated to each teaching task, among online and onsite university-level social science faculty. One hundred thirty-six social science faculty members were allocated into two groups…

As introductory college science courses transition from large, passive lectures to more student-centered active learning environments, additional instructional support may be needed. Peer Learning Assistants (PLAs) can aid course transformations by helping facilitate active learning and peer engagement among students in the classroom. Pedagogical…

Training in chemistry is essential for undergraduate medical students; however, at the National University of Colombia, basic chemistry courses are associated with high fail rates and low academic performance with regard to first semester students, especially in vulnerable special admission populations. A longitudinal study was carried out via…

Despite focused effort and attention over recent years, many potential barriers to progression and success remain within Higher Education. This study focuses on a cohort of 168 students studying on two semester-long Foundation Year Biological Sciences modules delivered at the University of East Anglia in the academic year 2021/22. These modules…

Background: Effective teaching of university chemistry in an online environment not only requires teachers to have specific discipline content knowledge; it also requires them to have knowledge and skills in technology-enhanced teaching practices. When transitioning from traditional face-to-face teaching into online contexts, teachers must learn…

With the call for reformed teaching practices in STEM education, there is a need to spread effective teaching practices to classrooms. Affective drivers can lead an instructor to improve their teaching practices, but they are infrequently addressed or recognized. This case study followed one instructor through her General Chemistry course over a…

Field biology courses can be formative learning experiences that develop students' science identities. Yet, they can also pose challenges to students that may disaffirm their science identities--especially to those who identify with underrepresented, excluded, and minoritized groups. It is largely unknown how students' social (e.g., gender) and…

A dual-enrollment course was designed in which the elementary concepts of organic chemistry were introduced to high school students. Students were assessed at the end of the term using an American Chemical Society (ACS) standardized exam. The same exam was given to corresponding traditional on-campus sections of the same class taught by the same…

Herein we present an engaging description of the existent analogy between social distancing during the COVID-19 pandemic and the collision cross-section of particles as defined in the collisional model for a chemical reaction. In addition, the link between collision cross-sections and kinetic rate constants is thoroughly established, bridging…

Recently there has been a push for more student-centered learning in the undergraduate classroom as a way to enhance student learning outcomes. One tool utilized in many Anatomy and Physiology courses is case studies of the material being presented. These allow students to apply their knowledge to a real-world scenario they may encounter in their…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] A level of curricular design, called "design tactics," is identified to fill a gap in the research literature between the broad principles that guide curriculum development and the detailed writing of specific activities and lessons. The use of…
