While several engineering and science disciplines, including biology and environmental science, have greatly benefited from adopting a systems thinking approach, its extension to chemistry education is a much more recent advancement. The initial body of literature in this direction has largely surveyed the feasibility for systems thinking in…

TNT is both toxic and explosive, and therefore, the detection of TNT represents an environmental concern and a security concern. Dogs are often used for detection, but other methods are needed. This laboratory investigates a ruthenium bipyridine ([Ru(bpy)[subscript 3]][superscript 2+]) luminescence-based trinitrotoluene (TNT) sensor. Students will…

Research has shown that the use of practical examples in undergraduate education promotes the retention of historically underrepresented students in STEM majors and lowers achievement gaps within courses. Since many students of color and women aspire toward careers in healthcare and the pharmaceutical industry, efforts to incorporate medicinal…

A laboratory exercise for undergraduate advanced students of enzymology and biocatalysis is presented. Since enzyme assays can be quenched or continuous, this experiment compares the performance of two quenching agents for lactase, in a continuous setup. Enzymatic activity of [beta]-galactosidase ("Aspergillus oryzae") was determined…

We examine students' challenges in determining the number of distinct many-particle stationary states for a system of noninteracting identical particles, focusing on how these insights guided the design, validation, and evaluation of a quantum interactive learning tutorial (QuILT) to aid students' understanding. Specifically, we focus on systems…

Recently, interest in understanding the prospects of virtual environments, specifically virtual reality laboratories (VR Lab) -- those that involve a first-person practica experience via a desktop computer or head-mounted display -- in science education has increased. Seemingly ingrained in the process of implementing a VR Lab is a supposition of…

Generative large language models (LLMs) like ChatGPT can quickly produce informative essays on various topics. However, the information generated cannot be fully trusted, as artificial intelligence (AI) can make factual mistakes. This poses challenges for using such tools in college classrooms. To address this, an adaptable assignment called the…

This article reports on the implementation of a CURE project in an upper-level analytical chemistry course to engage a larger number of students in research at a primarily undergraduate institution (PUI). The lab course syllabus was modified to provide students with an opportunity to experience the process of conducting research through a project…

Peer learning has become a central feature in many postsecondary classrooms. Many peer learning activities feature near-peer instructors who had previously completed the course and who later serve as peer leaders. There are relatively few examples of activities in which students in a course act as true peer instructors for their classmates. One…

One of the more difficult concepts introduced in the first-year undergraduate course, general chemistry, is that of chirality. Typically, left and right hands are the common, macroscopic objects of reference used to demonstrate the quality of being nonsuperimposable, followed by the use of a mirror and molecular models, to illustrate molecular…

Quantitative literacy is a foundational component of success in STEM disciplines and in life. Quantitative concepts and data-rich activities in undergraduate geoscience courses can strengthen geoscience majors' understanding of geologic phenomena and prepare them for future careers and graduate school, and provide real-world context to apply…

This report describes the implementation of a laboratory exercise for an advanced biochemistry or enzyme kinetics class at the undergraduate or graduate level, designed to improve understanding of protein conformational changes associated with the binding of a ligand. Students measure the fluorescence changes induced by the conformational…

Whereas extensive studies have examined the effectiveness of inquiry-based learning in chemistry education, few have tracked undergraduate performance throughout the college chemistry curricula. In this study, we describe an instructional model of conceptual learning and inquiry-based practices (CLIP) and assess students' transformation of…

This sequence of labs was developed for an upper level undergraduate cell biology course at Fairfield University. The labs are based on the use of the K562 human erythroleukemia cell line, a model system that is exceptionally amenable to an undergraduate cell biology lab course due to its ease of maintenance and propagation and usefulness for…

In a two-step synthesis starting with Ni(CH[subscript 3]COO)[subscript 2] ·4H[subscript 2]O and salicylaldehyde, students prepare Nethyl and N-isopropyl Ni(II) Schiff base (imine) complexes. After isolation and recrystallization, the products are characterized by room-temperature magnetic susceptibility measurements, FTIR spectroscopy, and…
