A comparison of the experiences of both organic and analytical lab faculty during the COVID-19 pandemic distance learning initiative is described here. Faculty of both lab courses experienced four shared challenges in the transition to the online format: (1) experimental implementation; (2) assessments and postlab activities; (3) technological…

The Reaction Coordinate Diagram Inventory (RCDI) has been developed to measure student thinking and confidence with reaction coordinate diagrams (RCDs) and their correspondence to reaction mechanisms. The RCDI was designed using a sequential mixed-methods protocol, such that the questions and distractors in the instrument were generated based on…

Development of three-dimensional (3D) printing technology has started a new chapter for in-classroom modeling of chemical molecules. The technology provides the opportunity to design and produce various types of personalized models. However, using classical 3D printers is time consuming, and it is hard to involve students in the modeling process…

Due to immense cost reduction and routine commercial availability, 3D printing has become the cutting-edge technology with enormous potential--also for educational and applied chemistry. It opens the opportunity to print custom-made reactors, such as (micro) flow reactors. In addition, 3D-printing technology can simplify chemical reactions, such…

The mathematical method of linear equations involving the coefficients of the equation of a chemical reaction can be used to balance the equation of nearly every chemical reaction. For its application, only the rules of simple algebra need be known. Hence, the method could even be used by students of an elementary chemistry course.

In this paper, we develop a general but very simple mathematical foundation for the predefined coefficient graphical method of Hückel molecular orbital theory (HMO). We first present the general solution for the recurrence relation of the coefficients of Hückel molecular orbitals (MOs). Subsequently, for all the three unbranched hydrocarbons,…

Classroom observation data using tools such as the Classroom Observation Protocol for Undergraduate STEM (COPUS) are frequently collected in instructional settings for large-scale research studies and program assessment. While COPUS data may be provided to instructors, it is often provided with little or no guidance on how the data can be used to…

The fundamental principles and applications of thermodynamics and single-component phase equilibrium are used to explain and quantitatively analyze the operation and performance of the vapor-compression refrigerator (VCR). Carbon dioxide is used as the refrigerant. The four processes (or steps) that comprise the VCR refrigeration cycle are…

The autumnal leaf color change is a familiar phenomenon to most students living in temperate climate zones. The extraction and analysis of the pigments of the autumn leaves provide an engaging way to study the phenomenon utilizing both simple as well as more sophisticated analytical methods. In this laboratory experiment, students extract the red…

A systems thinking approach to incorporating green chemistry and safety into laboratory culture is vital, as chemists will be at the molecular level of the innovative solutions to our global challenges. Training chemists to have the skills and culture to accomplish this feat in the safest way possible is pivotal to safe working conditions within…

Learning gains associated with multiple-choice testing formats that provide immediate feedback (e.g., IFAT®) are often greater than those for typical single-choice delayed feedback formats (e.g. Scantron®). Immediate feedback formats also typically permit part marks unlike delayed feedback formats. The present study contrasted IFAT® with a new…

A course centered around transition-metal catalysis in modern drug discovery was designed to illustrate the central role of organic chemistry in driving small-molecule drug development. The course highlighted both fundamental and applied concepts, first with a focus on the drug discovery process, followed by foundational principles in catalysis…

We describe here a 4 hour experimental session based on reaction monitoring of the degradation of an organic pollutant via a Fenton-like reaction. An aqueous solution of p-nitrophenol is treated with hydrogen peroxide and magnetite, and the progress of the reaction is monitored by UV-vis spectrophotometry and/or gas chromatography using an…

Each year, a large number of higher education students in the UK transfer from programs at further and higher education colleges to the second or third year of a bachelor's degree. The success of this movement is largely dependent on how closely the curricula of the two programs are aligned. Over the past two years, students from the Higher…

The objective of this study is to determine current medical students' perspective on the importance of Organic Chemistry in premedical curriculum, or if they see more benefit in a taking a different course. Previous literature has focused on premedical students, but the current study focuses on current medical students. A qualtrics survey was sent…
