Le, Christine M.; Morra, Barbora – Journal of Chemical Education, 2019
The tutorials of a second-year undergraduate organic chemistry course have been modified to include a retrosynthetic exercise in conjunction with a Molecule of the Week (MoW) challenge. In contrast to the original tutorial assignments in the course, which primarily focused on completing simple reaction roadmaps, the new tutorials place a heavier…

Bain, Kinsey; Rodriguez, Jon-Marc G.; Towns, Marcy H. – Journal of Chemical Education, 2019
The themes discussed in this study relate to how students reason about the information encoded in rate constants, which is important for developing a deep understanding of chemical kinetics at the molecular level. This study is part of a larger project centered more generally on students' understanding and use of mathematics in chemical kinetics.…

Mutambuki, Jacinta M.; Fynewever, Herb; Douglass, Kevin; Cobern, William W.; Obare, Sherine O. – Journal of Chemical Education, 2019
Integrating authentic research-based experiences that mimic real-world scientific practices and relevance to student personal life into a chemistry curriculum can make abstract chemical principles more palpable to students. Unfortunately, many reported research-based experiences chemistry laboratory experiments lack relevance to a student's…

Yong, Fang; Zhu, Qiuhong; Zhang, Guohao; Tao, Guohong; Qin, Song – Journal of Chemical Education, 2019
The stated purpose of this paper is to provide a simple and quick method to assemble pH electrodes using readily available materials. The present assembled electrodes are comparable with commercial pH electrodes, with accuracy for pH determination in the range 2-12. Furthermore, the constructed simple pH electrodes exhibit a fast and stable…

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…

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…

Hoffmann, Heiko; Tausch, Michael W. – Journal of Chemical Education, 2018
An inexpensive self-made apparatus for photochemical experiments was developed and has been tested to facilitate the inclusion of photoreactions in undergraduate teaching laboratories despite budget constraints. The core setup allowing the selection of defined wavelengths in the visible and UV regions is made of commercially available components…

Martin, James D.; Nock, Katherine A. – Journal of Chemical Education, 2018
The National Research Council's Framework for K-12 Science Education articulates the need to shift science curricula from being a collection of discrete facts to curricula that integrate core ideas and practices. To help teachers better integrate content and to respond to expressed frustration regarding extensive lists of standards often presented…

Zheng, Shao-Liang; Campbell, Michael G. – Journal of Chemical Education, 2018
A strategy for incorporating crystallography laboratory practice into various experimental chemistry courses for undergraduates is described. The flexible approach that relates key concepts to hands-on activities allows students to draw an immediate connection between crystallography theory and their own lab experiences, leading to a deeper…

Herrington, Deborah G.; Sweeder, Ryan D. – Journal of Chemical Education, 2018
Recent articles in this "Journal" have advocated for focusing instruction on core ideas of the discipline and moving assessment beyond content knowledge to also eliciting evidence about what students can do with their knowledge. Yet, the deep connected learning supported by this kind of instruction and assessment requires students to…

Cuartero, María; Crespo, Gastón A. – Journal of Chemical Education, 2018
Because traditional laboratory practices in advanced chemistry education are being replaced by inquiry-based approaches, we present herein a new laboratory activity based on a small research project that was designed and executed by students. The laboratory project aims at answering a well-defined research question: how far can potentiometric…

Halpern, Arthur M.; Marzzacco, Charles J. – Journal of Chemical Education, 2018
A spreadsheet-based project is presented that is designed to enhance and expand student understanding of phase transition properties of pure water and ideal and nonideal (electrolyte) aqueous solutions. Using fundamental principles of classical and statistical thermodynamics, students calculate the melting and boiling points, the enthalpies and…

McGill, Tracy L.; Williams, Leah C.; Mulford, Douglas R.; Blakey, Simon B.; Harris, Robert J.; Kindt, James T.; Lynn, David G.; Marsteller, Patricia A.; McDonald, Frank E.; Powell, Nichole L. – Journal of Chemical Education, 2018
This article describes the process of designing a new four-year curriculum at Emory University. Acknowledging the limitations of traditional curricula and pedagogy, the major goals of this reform effort include an emphasis on core ideas and scientific practices rather than content and historical course boundaries in order to convey the excitement,…

Masania, Jinit; Grootveld, Martin; Wilson, Philippe B. – Journal of Chemical Education, 2018
Analytical chemistry has often been a difficult subject to teach in a classroom or lecture-based context. Numerous strategies for overcoming the inherently practical-based difficulties have been suggested, each with differing pedagogical theories. Here, we present a combined approach to tackling the problem of teaching analytical chemistry, with…

Boyd-Kimball, Debra; Miller, Keith R. – Journal of Chemical Education, 2018
Laboratory courses are often designed using step-by-step protocols which encourage students to conduct experiments without thinking about what they are doing or why they are doing it. Such course design limits the growth of our students as scientists and can make it more difficult for a student to transition to the expectations of a research…
