Cooper, Melanie M.; Stowe, Ryan L.; Crandell, Olivia M.; Klymkowsky, Michael W. – Journal of Chemical Education, 2019
The fundamental structure of a typical mainstream two-semester organic chemistry course, populated mostly by life science majors and taught at universities throughout the United States, has changed little since the 1970s. However, much of the research on learning in organic chemistry has been devoted to characterizing student difficulties of…

Wu, Nancy; Hall, Ariana O.; Phadke, Sameer; Zurcher, Danielle M.; Wallace, Rachel L.; Castañeda, Carol Ann; McNeil, Anne J. – Journal of Chemical Education, 2019
Introductory-level laboratory courses provide students with hands-on experience using the discipline's tools and theories. These courses often rely on recipe-based experiments due to the constraints of large enrollments, short lab periods, and the desire to minimize complexity. In addition, covering a breadth of topics can lead to a fragmented…

Baldwin, Bruce W.; Kuntzleman, Thomas S. – Journal of Chemical Education, 2018
The separation of chamazulene from hydrophilic contaminants present in blue tansy oil provides a visually engaging example of two common techniques: extraction and thin-layer chromatography (TLC). This application uses liquid CO[subscript 2] as a lipophilic solvent to pull a brilliant blue hydrocarbon molecule, chamazulene, out of or through a…

Hinds, Elsa M.; Shultz, Ginger V. – Journal of Chemical Education, 2018
The introductory chemistry sequence is a common pathway for undergraduates pursuing science, technology, engineering, and math (STEM) and prehealth careers. Student's academic decision-making has far-reaching consequences for their trajectory, including persistence in the major and ultimate career choice. This phenomenon was studied using a survey…

Cooper, Melanie M.; Posey, Lynmarie A.; Underwood, Sonia M. – Journal of Chemical Education, 2017
In this paper we discuss how and why core ideas can serve as the framework upon which chemistry curricula and assessment items are developed. While there are a number of projects that have specified "big ideas" or "anchoring concepts", the ways that these ideas are subsequently developed may inadvertently lead to fragmentation…

Chaytor, Jennifer L.; Al Mughalaq, Mohammad; Butler, Hailee – Journal of Chemical Education, 2017
Online prelaboratory videos and quizzes were prepared for all experiments in CHEM 231, Organic Chemistry I Laboratory. It was anticipated that watching the videos would help students be better prepared for the laboratory, decrease their anxiety surrounding the laboratory, and increase their understanding of the theories and concepts presented.…

Stowe, Ryan L.; Cooper, Melanie M. – Journal of Chemical Education, 2017
Organic chemistry is often promoted as a course designed to cultivate skill in scientific "ways of thinking." Expert organic chemists perceive their field as one in which plausible answers to complex questions are arrived at through analytical thought processes. They draw analogy between problem solving in organic chemistry and diagnosis…

Jafari, Mina; Welden, Alicia Rae; Williams, Kyle L.; Winograd, Blair; Mulvihill, Ellen; Hendrickson, Heidi P.; Lenard, Michael; Gottfried, Amy; Geva, Eitan – Journal of Chemical Education, 2017
In this paper, we report on the implementation of a novel compute-to-learn pedagogy, which is based upon the theories of situated cognition and meaningful learning. The "compute-to-learn" pedagogy is designed to simulate an authentic research experience as part of the undergraduate curriculum, including project development, teamwork,…

Cersonsky, Rose K.; Foster, Leanna L.; Ahn, Taeyong; Hall, Ryan J.; van der Laan, Harry L.; Scott, Timothy F. – Journal of Chemical Education, 2017
Despite the prevalence of polymers in modern everyday life, there is little introduction to the topic in science education throughout primary or secondary schooling in the United States. Of the few states that do include polymer education, this is only found at the high school level, primarily in biology or chemistry. Over the past year, we have…

Yip, Tor; Melling, Louise; Shaw, Kirsty J. – Journal of Chemical Education, 2016
An online instructional database containing information on commonly used pieces of laboratory equipment was created. In order to make the database highly accessible and to promote its use, QR codes were utilized. The instructional materials were available anytime and accessed using QR codes located on the equipment itself and within undergraduate…

Zurcher, Danielle M.; Phadke, Sameer; Coppola, Brian P.; McNeil, Anne J. – Journal of Chemical Education, 2016
Feedback-driven online homework systems provide students with a comprehensive set of practice questions that can accompany and enhance other instructional resources. However, the available e-homework systems do not contain content that aligns well with our course objectives, provide too few questions in key areas, and use assessment format(s) that…

de la Pen~a, Lisandro Herna´ndez – Journal of Chemical Education, 2016
The solution of simple kinetic equations is analyzed without referencing any topic from differential equations or integral calculus. Guided by the physical meaning of the rate equation, a systematic procedure is used to generate an approximate solution that converges uniformly to the exact solution in the case of zero, first, and second order…

Evans, Hedeel Guy; Heyl, Deborah L.; Liggit, Peggy – Journal of Chemical Education, 2016
This biochemistry laboratory course was designed to provide significant learning experiences to expose students to different ways of succeeding as scientists in academia and foster development and improvement of their potential and competency as the next generation of investigators. To meet these goals, the laboratory course employs three…

Shultz, Ginger V.; Gottfried, Amy C.; Winschel, Grace A. – Journal of Chemical Education, 2015
General chemistry is a gateway course that impacts the STEM trajectory of tens of thousands of students each year, and its role in the introductory curriculum as well as its pedagogical design are the center of an ongoing debate. To investigate the role of general chemistry in the curriculum, we report the results of a posthoc analysis of 10 years…

Tomasik, Janice Hall; LeCaptain, Dale; Murphy, Sarah; Martin, Mary; Knight, Rachel M.; Harke, Maureen A.; Burke, Ryan; Beck, Kara; Acevedo-Polakovich, I. David – Journal of Chemical Education, 2014
Motivating students in analytical chemistry can be challenging, in part because of the complexity and breadth of topics involved. Some methods that help encourage students and convey real-world relevancy of the material include incorporating environmental issues, research-based lab experiments, and service learning projects. In this paper, we…
