Access to laboratory facilities and associated instrumentation represents a major barrier to learning in physical science education, due to constraints introduced by limited time and financial resources, cost of acquisition, and health and safety requirements. Virtualized laboratories offer some mitigation of these problems but may also introduce…

An introductory normal phase column chromatography experiment is described and evaluated for second year undergraduate chemistry laboratory class. The experiment involves a nucleophilic substitution yielding a crude mixture of reactant and one product, both of which are brightly colored and contrasting, creating a clearly visual separation when…

Medicinal chemistry, as the core curriculum of the pharmaceutical engineering major, contains complex knowledge systems and scattered knowledge points. A medicinal chemistry course covers more than 50kinds of drugs divided into 11 categories including antibiotics, antiparasitic drugs, anesthetics, nonsteroidal anti-inflammatory drugs, and nervous…

A flipped classroom describes a class where students complete readings and watch lectures outside of class, while in-class time is spent on activities to practice content learned. The implementation of a flipped classroom approach has been shown to increase student learning and student enjoyment of courses. This paper describes using the flipped…

Systems thinking in chemistry education (STICE) has been proposed as an approach that could better equip students with abilities to connect their chemistry knowledge with other disciplines and with the skills needed to tackle complex global issues. However, educational change in chemistry is a complex effort that involves many interconnected…

Retention of students' attention in general chemistry courses stands as one of the main challenges that educators are facing in classes of any size and is especially prevalent with classes composed of mixed majors. Herein, we describe our experience with introducing short, 10 min student lectures ("flash talks") on popular chemistry…

Identifying and naming inorganic compounds is sometimes a challenge for many first-year chemistry and engineering students; however, these difficulties can be overcome after extensive practice using homework sets based on naming inorganic compounds or applying inorganic nomenclature rules. Werner is a card game in honor of Professor Alfred Werner…

This project introduces green chemistry to the undergraduate laboratory through two pedagogical techniques: undergraduate research and guided-inquiry. Through these two learning activities, an efficient synthetic procedure for the PRINS cyclization of citronellal into isopulegol, focused on minimizing negative environmental impact, was developed.…

Instrumentation plays a critical, ubiquitous role in modern chemistry. The undergraduate chemistry curriculum must therefore cultivate students' ability to investigate chemical phenomena via relevant instruments. The instructional laboratory serves as the primary context in which undergraduates learn about instrumentation, where use of instruments…

Catalysis and catalytic cycles are widely used in both research and industry. The addition of a catalysis experiment into the undergraduate laboratory curriculum is important and necessary training to expand student learning. Here, an experiment demonstrating iron-based tandem catalysis was developed and implemented in an organic chemistry course…

An educational lattice model is proposed for the investigation of the influence of the density and indirectly of the pressure on the chemical equilibrium of the ideal gas phase reaction A [equilibrium] 2B. The model can be introduced by a board game simulating a stochastic process. This game can also be used to set up a corresponding computer…

The focus in teaching and research is shifting from a traditional perspective of information literacy (IL) as a specific set of general, mostly text-based skills to a more comprehensive understanding of the complex aspects that constitute IL as an ongoing, context-specific process. However, there is a need for further insight into the social and…

FINDIF is a Windows application that numerically solves the one-dimensional (1D) Schrödinger equation and displays the eigenstates, eigenvalues, and probability density of the system. FINDIF accepts both nonperiodic and periodic 1D potential energy functions as input and uses the finite difference method to evaluate the energy of the quantum…

The two-semester General Chemistry laboratory sequence for nonchemistry majors at James Madison University has recently made the transition from expository, confirmation experiments to project-based (first semester) and research-based (second semester) curricula; this narrative will describe the development and current state of the Brewing Science…

This research developed learning activities for students to explore and connect the concepts of acid-base titration, equivalence points, pK[subscript a], and molar absorption coefficients. Polyphenolic compounds consisting of p-coumaric acid (CMA), caffeic acid (CFA), and 3,4,5-trihydroxycinnamic acid (3,4,5-THCA) were selected as study models.…
