Sumalatha Peddi; Jacob R. Franklin; C. Scott Hartley – Journal of Chemical Education, 2024
Chemical reactions that mimic the function of ATP hydrolysis in biochemistry are of current interest in nonequilibrium systems chemistry. The formation of transient bonds from these reactions can drive molecular machines or generate materials with time-dependent properties. While the behavior of these systems can be complicated, the underlying…

Sabrina Barakat – ProQuest LLC, 2024
Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I, reintroduced in Organic Chemistry I, and then utilized throughout other higher-level chemistry courses. A molecule or ion can be said to exhibit resonance when it can be represented by two or more chemical structures (i.e., Lewis structures) that…

Metal-organic frameworks (MOFs) are a class of porous materials that are often crystalline with high surface area and structural tunability. In this laboratory experiment designed for inorganic chemistry students at the undergraduate level, students complete a two-step experiment where they will first (i) synthesize two isostructural…

Chemistry undergraduate curricula typically place Nuclear Magnetic Resonance (NMR) lectures under either Organic Chemistry or Spectroscopy courses, aiming for students to acquire basic knowledge for the determination of the structure of simple organic compounds. On the other hand, regarding laboratory practice, NMR is frequently disregarded by…

Kaisar Tursyngozhayev; Nusret Kavak; Nurlan K. Akhmetov – Journal of Chemical Education, 2024
The teaching and learning of chemistry can be challenging due to the complex and abstract nature of the subject matter. Traditional methods of instruction often struggle to engage students and facilitate an understanding of essential chemical concepts. To address this, an innovative card game, "Compound Chain", was developed and…

Chao-Tun Cao; Chenzhong Cao – Journal of Chemical Education, 2023
The inductive effect is one of the very important concepts of electronic effects in organic chemistry. In traditional teaching methods, only the origin, transmission mode, and decay of the inductive effect are introduced briefly, which is not conducive to students' complete understanding of the inductive effect. This work developed a new method to…

Kassem Hallal; Sami Tlais – Journal of Chemical Education, 2023
Different molecular representations are usually used to depict the three-dimensional (3D) structure of organic compounds. Mastering the skill of interconverting one form into another is essential for students to ensure success in organic chemistry. The traditional and recently developed methods for completing such interconversions that rely on 3D…

Kendall M. Zammit; Megan C. Connor; Jeffrey R. Raker – Chemistry Education Research and Practice, 2024
A national survey on chemistry instructional laboratories was administered to faculty members at four-year postsecondary institutions in the United States for the purpose of exploring levels of inquiry-based instruction implemented in laboratory courses. Respondents were asked to rate the level of choice their students had in deciding six key…

Caroline J. Crowder; Brandon J. Yik; Stephanie J. H. Frost; Daniel Cruz-Rami´rez de Arellano; Jeffrey R. Raker – Journal of Chemical Education, 2024
Understanding reaction mechanisms is integral to success in organic chemistry; however, prior research suggests that learners struggle with recognizing the importance of underlying implicit features in reaction mechanisms. Because of this struggle, understanding how learners' reason about reaction mechanisms and developing assessments to elicit…

Vincent Natalis; Bernard Leyh – Chemistry Education Research and Practice, 2025
Entropy and the second law of thermodynamics have long been identified as difficult concepts to teach in the physical chemistry curriculum. Their highly abstract nature, mathematical complexity and emergent nature underscore the necessity to better link classical thermodynamics and statistical thermodynamics. The objectives of this systematic…

Ernest Koranteng – Science Education International, 2024
This study aimed to uncover common difficulties and possible areas for improvement by focusing on the approaches and errors made by 3rd-year undergraduate chemistry students in solving organic synthesis problems. The study employed a purposive sampling technique to select 112 undergraduate chemistry major students to participate in this study.…

The preparation of ethyl acetoacetate is a distinctive, century-old classic organic chemistry laboratory project. Ethyl acetate and sodium metal (sodium ethoxide) are reacted by Claisen ester condensation to produce the sodium salt of ethyl acetoacetate and then obtain the refined product by acidification as well as washing, drying, and…

Ricardo Matos; Mikeas Silva de Lima; Guilherme Balestiero da Silva; Salete Linhares Queiroz – Journal of Chemical Education, 2024
In 2002, the Swedish National Food Agency and researchers from Stockholm University made an announcement regarding the presence of acrylamide in carbohydrate-rich foods that are exposed to high temperatures, with cereals, potatoes, and coffee possibly being the most significant sources of ingestion. Although limited data are available on assessing…

Ayesha Farheen – ProQuest LLC, 2023
Molecular representations that show chemical bonding are ubiquitous in general and organic chemistry. These help in communicating chemistry concepts that are fundamental to understanding "how" and "why" molecules interact. The goal of this dissertation work is to offer an evidence-based report on the affordances and limitations…
