Kolonko, Erin M.; Kolonko, Kristopher J. – Journal of Chemical Education, 2019
Strategies for teaching NMR spectral interpretation in the undergraduate organic chemistry curriculum are often faculty-centered and can lead to student reliance on rote memorization and "guess and check" methods rather than critical-thinking skills for structure determination. This article describes a student-focused methodology for the…

Wright, Lyniesha C.; Oliver-Hoyo, Maria T. – Journal of Chemical Education, 2019
A physical model has been designed to help students visualize concepts involved when solving infrared spectra. The physical model uses balls and springs to incorporate the harmonic oscillator model and Hooke's law to study dynamic vibrations within diatomic molecules. Various concepts are addressed with the model to abstract principles about how…

Drew, Steven M.; Gross, Deborah S.; Hollingsworth, William E.; Baraniak, Thomas; Zall, Christopher M.; Mann, Kent R. – Journal of Chemical Education, 2019
Time-resolved luminescence lifetime measurements are an important photophysical technique. However, access to this technique at the undergraduate level is limited by the expense of the instrumentation needed to create the well-defined light pulses required to measure the luminescence decay of an excited state molecule. We present here an…

Santos-Díaz, Stephanie; Hensiek, Sarah; Owings, Taylor; Towns, Marcy H. – Journal of Chemical Education, 2019
Previous work has shown a misalignment between the goals of faculty and students for laboratory coursework. Although faculty often list learning techniques and developing critical thinking skills as goals for laboratory, students tend to focus on affective goals, such as finishing lab early and obtaining good grades. The goals of faculty have been…

Elgrishi, Noémie; Rountree, Kelley J.; McCarthy, Brian D.; Rountree, Eric S.; Eisenhart, Thomas T.; Dempsey, Jillian L. – Journal of Chemical Education, 2018
Despite the growing popularity of cyclic voltammetry, many students do not receive formalized training in this technique as part of their coursework. Confronted with self-instruction, students can be left wondering where to start. Here, a short introduction to cyclic voltammetry is provided to help the reader with data acquisition and…

Sanders, Wesley C.; Iles, Peter; Valcarce, Ron; Salisbury, Kyle; Johnson, Glen; Lines, Aubry; Meyers, John; Page, Cristofer; Vanweerd, Myles; Young, Davies – Journal of Chemical Education, 2018
This paper describes a laboratory exercise used to address the ongoing need for nanotechnology-related, hands-on laboratory experiences for undergraduate students. Determination of the electrochemical behavior of student-fabricated silver nanogrids is reported. Students successfully used cyclic voltammetry to analyze silver nanogrids printed using…

Cunningham, William Patrick; Xia, Ian; Wickline, Kaitlyn; Huitron, Eric Ivan Garcia; Heo, Jun – Journal of Chemical Education, 2018
A procedure for the study of structural differences and intermolecular attraction between ethanol and 1-butanol based in laboratory work is described. This study provides comparisons of data retrieved from both a determination of boiling point and gas chromatography traces for the mixture. The methodology reported here should provide instructors…

Highland, Zachary L.; Saner, ChaMarra K.; Garno, Jayne C. – Journal of Chemical Education, 2018
Experiments are described that involve undergraduates learning concepts of nanoscience and chemistry. Students prepare nanopatterns of organosilane films using protocols of particle lithography. A few basic techniques are needed to prepare samples, such as centrifuging, mixing, heating, and drying. Students obtain hands-on skills with nanoscale…

Quattrucci, Joseph G. – Journal of Chemical Education, 2018
A new method for teaching advanced laboratories at the undergraduate level is presented. The intent of this approach is to get students more engaged in the lab experience and apply critical thinking skills to solve problems. The structure of the lab is problem-based and provides students with a research-like experience. Students read the current…

Raboh, Ghada – Journal of Chemical Education, 2018
A high performance liquid chromatography (HPLC) experiment for the upper level analytical chemistry laboratory is described. The students consider the effect of mobile-phase composition and pH on the retention times of ionizable compounds in order to determine the acid dissociation constant, K[subscript a], of a phenolic acid. Results are analyzed…

Jewitt, Sarah; Sutphin, Kathy; Gierasch, Tiffany; Hamilton, Pauline; Lilly, Kathleen; Miller, Kristine; Newlin, Donald; Pires, Richard; Sherer, Maureen; LaCourse, William R. – Journal of Chemical Education, 2018
This article examines the ways that a shared faculty experience across five partner institutions led to a deep awareness of the curriculum and pedagogy of general chemistry coursework, and ultimately, to a collaborative action plan for student success. The team identified key differences and similarities in course content and instructional…

Harrp, David N. – Journal of Chemical Education, 2018
Copying adjacent answer sheets on the oft-used multiple-choice exams can be prevented if exam material is scrambled. The latter mode has been a requirement for all exams of this type at McGill University for 26 years. Cheating by copying has been reduced to nearly zero in this time. The experiment carried out used permissive seating and a single…

Irby, Stefan M.; Borda, Emily J.; Haupt, Justin – Journal of Chemical Education, 2018
Here, we describe the implementation a hybrid general chemistry teaching laboratory curriculum that replaces a portion of a course's traditional "wet lab" experiences with online virtual lab modules. These modules intentionally utilize representations on all three levels of the chemistry triplet-macroscopic, submicroscopic, and symbolic.…

Minkiewicz, Piotr; Darewicz, Malgorzata; Iwaniak, Anna – Journal of Chemical Education, 2018
A simple equation to calculate the oxidation states (oxidation numbers) of individual atoms in molecules and ions may be introduced instead of rules associated with words alone. The equation includes two of three categories of bonds, classified as proposed by Goodstein: number of bonds with more electronegative atoms and number of bonds with less…
