This study seeks to elucidate the fundamental principles underlying the hydration, hydrolysis, and enolization of [beta]-diketones, aiming to enhance students' comprehension of the link between fundamental chemical principles and the practical implications of keto-enol tautomerization and diketone-gem diol equilibrium in diverse chemical…

Traditional physical chemistry conceptions of reaction mechanism are formulated in terms of stationary points of an Arrhenius-style "energy profile" that differs sharply (in purpose and form) from the corresponding Robinson-style "arrow-pushing" mechanistic conceptions of organic chemistry. We show here how these diverse…

In chemistry, a eutectic mixture refers to a mixture of two or more components at which the lowest possible freezing point is observed. This phenomenon is covered in a wide range of curricula such as physics, chemistry, chemical engineering, and pharmacy to various depths. Despite the significance of this phenomenon in pharmaceutical compounding…

This laboratory experiment offers a research-style experience designed for senior undergraduate students in a multidisciplinary laboratory setting. The experiment focuses on the synthesis, characterization, and application of a cation-exchange membrane made of COF-SO[subscript 3]Na/PAN for ion separation. By participating in this practical…

This laboratory exercise integrates chemistry and biology concepts to give third/fourth-year undergraduate students an opportunity to apply knowledge from different subject areas to address a real-world biomedical issue such as pathogen inhibition using composite materials. It involves the preparation of a bacteria-derived cellulosic biopolymer…

In all fields of chemistry, it has become essential to use quantum chemical calculations and machine learning for explaining and predicting chemical phenomena. However, it is challenging to apply textbook knowledge to practical research. In this study, we developed teaching material based on computational chemistry to promote the integration of…

Crystal materials are an important pillar of advanced technology. Among them, the preparation of large-sized single crystal materials is of great importance for their practical application. Herein, we select the well-known nonlinear optical crystal KH[subscript 2]PO[subscript 4] and impressive deep-blue colored crystal CuSO[subscript…

Three-dimensional learning is the name given to the vision for science education described in the National Academies consensus report "A Framework for K-12 Science Education." Of the three dimensions described in the Framework, the Disciplinary Core Ideas and the Science and Engineering Practices have been enthusiastically adopted by…

The Chemistry Self-Concept Inventory (CSCI) is a widely used instrument within chemistry education research. Yet, agreement on its overall reliability and validity is lacking, and psychometric analyses of the instrument remain outstanding. This study examined the psychometric properties of the subscale and item function of the CSCI on 1140 high…

A central theme in introductory and advanced chemical education courses pertains directly to the transfer of electrons between atoms, ions, or molecules. This article presents theoretical treatments of electron transfer with specific attention toward applying these principles to experiment. The goal is to revitalize teaching electron transfer at…

OrgoPrep, a summer preparatory program integrating multiple active-learning elements (i.e., interactive videos with problem-solving and feedback, synchronous peer-led instruction, and collaborative work), was previously shown to improve academic outcomes in organic chemistry for all students. The present study examined how OrgoPrep differentially…

There has been a growing awareness that STEM education should incorporate a wide range of capabilities, in addition to providing traditional theoretical and practical knowledge. In line with these skills, entitled "professional skills," GTIIT has defined seven core competencies. The enhancement of two of these competencies, namely,…

Lecture capture videos were explored as beyond the classroom course materials in upper-level descriptive inorganic chemistry courses during Fall 2017, Fall 2018, and Fall 2020 semesters. Page views data from the learning management system (LMS) Canvas site served as a proxy for course content usage materials such as lecture capture videos. There…

The Maxwell distribution of speeds, f(v), is the starting point for the calculation of the transport coefficients in kinetic-molecular theory. Most physical chemistry textbooks follow a path to derive f(v) similar to that used by Maxwell, which makes it difficult for students to understand its relationship with the equilibrium state of the system,…

One of the unique advantages of electrochemistry is that the relationship between thermodynamics and kinetics is quantitative, which is the basis of voltammetry. Mathematical models of electrochemical systems take advantage of this relationship to predict the effect of changing a system property (e.g., concentration, scan rate, or rate constant)…
