We report here a second semester general chemistry laboratory project themed around chitosan-alginate bioplastics. With increasing awareness of plastic pollution in the environment and the awareness of the importance for materials which are either made from renewable resources or are biodegradable, this topic provides a relevant opportunity to…

In this study, diagnostic worksheets adopted from the Royal Society of Chemistry and microscale chemistry activities were employed to investigate teacher trainees' understanding of chemical compounds. The framework for the study was hinged on the constructivist theory. Participants in this study were 36 1st-year undergraduate teacher trainees of…

This "Science note" teaching lesson explores the possible reaction between the ions in a reaction mixture consisting of iron(II) iodide and potassium dichromate(VI) in acidified aqueous solution. The electrode potentials will be used to deduce any spontaneous reactions under standard thermodynamic conditions (298 K, 1 bar (approximately…

In Spring 2020, we began a study focused on the development of inclusive teaching practices in an undergraduate chemistry lecture course for non-STEM students. In the wake of the COVID-19 pandemic and ensuing educational disruptions, we changed the design of our study to focus on the learning and teaching experiences of students and instructors.…

This study, which was based on qualitative research design, aimed to examine the research trends and results of bibliometric mapping analyses of articles about the Flipped Classroom Model (FCM) in education in the past ten years. For this purpose, 126 articles published with the keywords; flipped classroom, education, social science, science,…

This work developed the Flint, Michigan water crisis as a modular case study for teaching traditional analytical chemistry concepts through the medium of environmental justice, power, and equity. An interdisciplinary framework was used to design, implement, and assess the case study in an effort to understand how the deliberate presence of…

The American Chemical Society (ACS) Committee on Minority Affairs (CMA) endeavors to support all chemistry faculty and staff as they educate all of our students during this pandemic. While the chemistry education community and the ACS have both provided resources as most institutions transitioned to virtual platforms, this pandemic…

The thermodynamic formalism of ideal solutions is developed in most of the textbooks postulating a form for the chemical potential of a generic component, which is adapted from the thermodynamics of ideal gas mixtures. From this basis, the rest of useful thermodynamic properties can be derived straightforwardly without further hypothesis. Although…

Counterfeiting and adulteration of prescription drugs, herbal products, and food supplements are a global challenge, causing serious economic loss to drug marketers and health implications for humans. Accordingly, accurate determination of the purity of pharmaceuticals is critical for the quality assurance of prescription drugs. Herein, the first…

Erioglaucine dye (FD&C Blue #1) can be used instead of methylene blue in the classic "blue-bottle" demonstration. Food items containing FD&C Blue #1 and reducing species such as sugars can therefore be used at the heart of this demonstration, which simply requires the addition of strong base such as sodium hydroxide lye.

Isothermal titration calorimetry was used to experimentally determine thermodynamic values for the ethylenediaminetetraacetic acid (EDTA)(aq) + M[superscript 2+](aq) reactions (M[superscript 2+] = Ca[superscript 2+] and Mg[superscript 2+]). Students showed that for reactions in a N-(2-hydroxyethyl)piperazine-N"-ethanesulfonic acid (HEPES)…

In today's complex world, there is a continued demand for recently graduated forensic chemists (criminalists) who have some background in forensic experimental techniques. This article describes modern forensic experimental approaches designed and implemented from a unique instructional perspective to present certain facets of crime scene…

There are two main difficulties in studying molecular symmetry of dihedral point groups. One is locating the C[subscript 2] axes perpendicular to the C[subscript n] axis, while the other is finding the s[subscript]d planes which pass through the C[subscript n] axis and bisect the angles formed by adjacent C[subscript 2] axes. In this paper, a…

Solubility is frequently introduced at the high school and introductory college levels through the symbolic domain using net ionic equations and solubility product constants. Students may become proficient with spectator ion cancellation and skilled with algorithmic mathematical applications of solubility without obtaining a deeper understanding…

The quality of the process of teaching is related to the behaviors shown by the teacher and their capability. In cases where teachers who have different training are expected to teach the same topic, teachers may make some alterations in the topics in question. Turkish education system has teachers who have different training but teach the same…
