Proficiency with instrumental analysis via GC-MS is an important skill for chemistry students. The application of analytical techniques and fundamental theoretical principles to real-world problems can be valuable learning exercises for undergraduates which can also improve their analytical thinking skills. Xylitol is generally considered safe for…

To improve the quality of education, it is important for teachers to have an understanding of action research. Action research is 'learning by doing', which involves identifying a problem, looking for a plan to resolve it, observing how successful it is and, if not satisfied, trying again. Action research helps educators to be more effective in…

An undergraduate organic chemistry laboratory experiment that provides an introduction to the concepts and practices of photoredox catalysis is reported. While undergraduate-level photochemistry experiments typically place emphasis on analytical properties of catalysts rather than synthetic applications, this experiment showcases the power and…

A novel laboratory curriculum is presented, developed around some common tasks of a laboratory researcher in chemistry: purification, synthesis, and measurement. The capstone of the sequence is an integrated laboratory, leading to a more independent research experience. Students who have completed this laboratory curriculum appear to perform…

Polymer chemistry is an integral part of art conservation graduate training programs. The list of materials used by artists and artisans and by conservators is vast, with the majority being polymeric in nature. Conservators use an array of polymers as coatings, adhesives, fills, supports, and structures. Aside from the chemistry of these…

This paper proposes a novel application of knowledge space theory for identifying discrepancies between the knowledge structure that experts expect students to have and the real knowledge structure that students demonstrate on tests. The proposed approach combines two methods of constructing knowledge spaces. The expected knowledge space is…

A novel educational chart that represents the acid--base behavior of 100 s-, p-, d-, and f-element oxides depending on the element's electronegativity and oxidation state was designed. An updated periodic table of said oxides was developed. A mathematical criterion based on the chart was derived which allows prediction of the behavior of…

The National Research Council's Framework for K-12 Science Education articulates the need to shift science curricula from being a collection of discrete facts to curricula that integrate core ideas and practices. To help teachers better integrate content and to respond to expressed frustration regarding extensive lists of standards often presented…

Informal chemistry education/chemistry outreach is ubiquitous with the chemical enterprise. However, little research has focused on the planning, implementation, or evaluation of these events. Results from a previous study suggest that college students involved with collegiate chapters of the American Chemical Society and Alpha Chi Sigma are…

Surface modification has been considered as a fundamental item in upper-division undergraduate and master courses. Thus, the development of experiments regarding processes and characterization of surface-modification phenomena is highly desired. In this article, we propose an electrochemical and computational study of widely used…

Traditional engineering textbooks are substantially limited by approaches relying on analytical solutions where most of the applications are described by differential equations without simple analytical solutions. An alternative is to design a textbook around computer-program-based simulations, where the simulations progressively evolve through…

At an advanced stage of learning quantum chemistry, undergraduate students usually encounter simple Hückel-molecular-orbital (HMO) theory, whose primitive approach gives very useful insight into the electronic structure of p-conjugated molecules. However, on one hand, computational HMO software, when programmed without using molecular symmetry,…

An interdisciplinary laboratory experiment was designed and carried out on the basis of the photo/electrochromism of N,N'-bis(cysteine)pyromellitic diimide (BCPD), suitable for organic chemistry laboratory I and physical chemistry laboratory II students. In the organic chemistry laboratory, students synthesized BCPD and studied its…

An integrated pair of experiments has been developed to introduce undergraduate students to the ways in which electrochemistry can complement conventional synthetic chemistry involving redox reactions. Students first use cyclic voltammetry and linear scan voltammetry to characterize and quantify the products of the reaction between…

Molecular symmetry plays a central role in chemistry education with regard to predicting chemical properties such as bonding and spectroscopic transitions. Better understanding of the symmetry of molecules requires high visual-spatial thinking ability. Conventional teaching methodologies, with limited teaching aides, fall short in providing a…
