Andrew Karatjas – Journal of College Science Teaching, 2024
Student self-assessment surveys were utilized to look at student study habits in several areas. Both self-reported study time and study methods were explored. Surveys were given to students after they received their graded exams. In a comparison with the federal definition for a credit hour (2 hours outside of class for each hour spent in class),…

David Keller; Jolanda Hermanns – Journal of Chemical Education, 2023
Scaffolds can be seen as a suitable tool to support students' learning chemistry. Digital task navigators, written scaffolds that support students in solving tasks in organic chemistry, were developed, used, and evaluated for this study. A paper task navigator was further developed into a digital task navigator, which included links to…

Michael W. Pelter; Libbie S. W. Pelter; Phillip I. Dinga; Nicholas E. Ernst; Madison L. Schultz – Journal of Chemical Education, 2023
A cornerstone activity in undergraduate organic laboratories revolves around students running instrumental analysis on their products and interpreting their spectra. They are left to link the theory they have learned in lecture to practical spectral interpretation. Students often memorize benchmark interpretations of peaks, such as the broad…

Norma Cavazos-Rocha; Olga Rodri´guez-Marti´nez; Amy Espinosa-Pedroza; Noemi´ Waksman-Minsky; Alma L. Saucedo – Journal of Chemical Education, 2023
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…

Yongwu He; Mo Chen; Jing Wang; Gaomei Zhao; Songling Han; Yang Xu; Yin Chen; Cheng Wang; Junping Wang – Journal of Chemical Education, 2023
The dangers of organic dye pollutants and environmental pollution improvement through photocatalytic degradation are important courses in applied chemistry programs in universities. Zinc oxide (ZnO)-based nanomaterials are potent catalytic agents against organic dyes, but few experiments are available for students to understand their role and…

Dongju Zhang – Journal of Chemical Education, 2023
This review describes a computational chemistry exercise aimed at enhancing the understanding of upper-division undergraduates in organic chemistry and physical chemistry regarding the structures and aromaticities of cyclobutadiene and cyclooctatetraene. This exercise exposes students to chemical problems that require computational methods as a…

James E. Patterson; Haley N. Hunsaker; Laurel C. Smith; Rebecca L. Sansom; Matthew C. Asplund – Journal of Chemical Education, 2024
Modifications are presented for the iodine clock reaction to introduce the concept of activity and to help students better appreciate molecular aspects of chemical equilibrium. The addition of an unreactive salt affects the activity of the reactants in the iodine clock reaction. The difference in activity affects how long the iodine clock reaction…

Katie Marie Q. Magnone; Ellen J. Yezierski – Journal of Chemical Education, 2024
When designing a study, the sampling method for selecting research participants is an important decision with a host of considerations. When designing a professional development (PD) program with a limited number of spaces, the method of choosing participants from the applicants is also important. When research and professional development are…

Jerry Easdon – Journal of Chemical Education, 2022
Water and an immiscible organic liquid are placed in a small plastic bottle. Ten small pieces of a notecard which is shaded on one side by crayon or pencil (graphite or colored) are cut out and placed inside the bottle. After capping and shaking, the notecard pieces float at the liquid-liquid interface with the shaded side facing the nonpolar…

Jinkun Fan; Yujie Li; Yiting Wei; Feng Liu; Dadong Lu; Tao Ye; Jie Dai; Xu Cheng – Journal of Chemical Education, 2023
The chlorination reaction of aromatic compounds is highly important for the synthesis of pharmaceutical products. As the most common chlorination reagent, chlorine is restricted from undergraduate laboratory experiment training due to its toxicity. In this work, we reported the chlorination of aromatic compounds with chlorine generated from the…

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…

Kvittingen, Lise; Sjursnes, Birte Johanne; Schmid, Rudolf – Journal of Chemical Education, 2021
In organic chemistry textbooks (S)-(-)-limonene, (-)-limonene or l-limonene, is often given credit for the smell of lemons, while the R-analogue, (+)-limonene or d-limonene, is credited with that of oranges. Results from two odor tests revealed that few persons in the test associated (R)-(+)-limonene with oranges and (S)-(-)-limonene with lemons,…

Ahlburg, Jakob Voldum; Menhinnitt, Zach; Thomas-Hunt, Jack; Saura-Mu´zquiz, Matilde; Christensen, Mogens – Journal of Chemical Education, 2021
In this experiment, students explore the synthesis and physical property characterization of the magnetic material strontium hexaferrite (SrFe[subscript 12]O[subscript 19]). SrFe[subscript 12]O[subscript 19] crystallites are prepared by a simple but fascinating sol-gel autocombustion synthesis. The prepared powder is compacted into pellets and…

Huizhu Zhang; Zhenhua Chen – Journal of Chemical Education, 2023
In this paper, we propose a novel method for deriving Russell-Saunders terms of complex atomic systems with an arbitrary number of equivalent electrons in orbitals with a higher azimuthal number. The method can be regarded as an extension of the classic works of Douglas, McDaniel, and Hyde but with several notable improvements, including the…
