Collison, Christina G.; Kim, Thomas; Cody, Jeremy; Anderson, Jason; Edelbach, Brian; Marmor, William; Kipsang, Rodgers; Ayotte, Charles; Saviola, Daniel; Niziol, Justin – Journal of Chemical Education, 2018
Reformed experimental activities (REActivities) are an innovative approach to the delivery of the traditional material in an undergraduate organic chemistry laboratory. A description of the design and implementation of REActivities at both a four- and two-year institution is discussed. The results obtained using a reformed teaching observational…

Oliveira, Deyvid G. M.; Rosa, Clarissa H.; Vargas, Bruna P.; Rosa, Diego S.; Silveira, Ma´rcia V.; de Moura, Neusa F.; Rosa, Gilber R. – Journal of Chemical Education, 2015
A five-week miniproject is described for an upper-division experimental organic chemistry course. The activities include synthesis of a phenylboronic acid via a Grignard reaction and its use in a Suzuki-Miyaura cross-coupling reaction. Technical skills and concepts normally presented in practical organic chemistry courses are covered, including…

Kam, Caleb M. T.; Levonis, Stephan M.; Schweiker, Stephanie S. – Journal of Chemical Education, 2020
The synthesis of 4-amino-3-nitrobenzoic acid methyl ester is a simple Fischer esterification reaction designed as an experiment for use in an introductory organic chemistry course. The compound was synthesized as a one-pot reaction within 30 min to 16 h, with 1 h producing a workable yield. The bright-yellow solid was purified using liquid--liquid…

Gibbons, Rebecca E.; Xu, Xiaoying; Villafañe, Sachel M.; Raker, Jeffrey R. – Educational Psychology, 2018
Affective factors such as the achievement emotions are considered critical for students' academic performance in STEM degree programmes and careers. In this study, a reciprocal causation model was tested between two affective factors: enjoyment and anxiety, and organic chemistry course performance. Each variable was measured three times in four…

Collins-Webb, Alexandra; Jeffery, Kathleen A.; Sweeder, Ryan D. – Journal of STEM Education: Innovations and Research, 2016
The move from general chemistry to organic chemistry can be a challenge for students as it often involves a transition from quantitatively-oriented to mechanistically-oriented thinking. This study found that the design of the general chemistry course can change the student experience of this transition as assessed by a reflective survey. The…

Morales, Christine; Chen, Franklin – Journal of Chemical Education, 2019
The effects of substitution on reaction rates are at the heart of both physical chemistry and organic chemistry. In this paper, we present a computational laboratory module to explore the effects of group substitution and isotopic substitution on reaction rates by using a readily accessible graphical interface, a computational engine, and…

Mullins, Joseph J.; Prusinowski, Allen F. – Journal of Chemical Education, 2019
A microwave-promoted synthesis of a carbocyclic curcuminoid has been developed for the undergraduate organic chemistry laboratory curriculum. The experiment features several teaching points: A novel Knoevenagel iminium-mediated condensation forms a highly conjugated, intensely colored natural product. Reaction occurs uniquely at the less acidic…

Ratniyom, Jadsada; Boonphadung, Suttipong; Unnanantn, Thassanant – International Journal of Environmental and Science Education, 2016
This study examined the effects of the introductory organic chemistry online homework on first year pre-service science teachers' learning achievements. The online homework was created using a web-based Google form in order to enhance the pre-service science teachers' learning achievements. The steps for constructing online homework were…

Yearty, Kasey L.; Maynard, Ryan K.; Cortes, Christina N.; Morrison, Richard W. – Journal of Chemical Education, 2020
Williamson ether experiments are commonly performed by students in undergraduate organic chemistry instructional laboratory courses. In this multioutcome experiment, students were provided 4-bromophenol and one of three alkyl halides: 1-bromopentane, 1-bromobutane, or 1-bromo-3-methylbutane. The alkyl halides served as the unknown component of the…

Carle, Myriam S.; Flynn, Alison B. – Chemistry Education Research and Practice, 2020
The concept of delocalization (i.e., resonance) is fundamental concept in organic chemistry but essential learning outcomes (LOs) have not previously been proposed nor has there been an analysis of how resonance is taught, despite indications in the literature that students have many non-canonical ideas about the concepts. To address this deficit,…

The instruction of high enrollment general and organic chemistry laboratories at a large public university always has curricular, administrative, and logistical challenges. Herein, we describe how we met these challenges in the transition to remote teaching during the COVID-19 pandemic. We discuss the reasoning behind our approach, the utilization…

Zhou, Ninger; Fischer, Christian; Rodriguez, Fernando; Warschauer, Mark; King, Susan – Journal of Computing in Higher Education, 2020
Self-efficacy has a strong influence on the learning and motivation of science students at the postsecondary level, especially in upper division science classes, which are key to student success in science majors. This empirical mixed methods research study (N = 205) examines the associations between students' participation in an online…

Winter, Julia E.; Engalan, Joseph; Wegwerth, Sarah E.; Manchester, Gianna J.; Wentzel, Michael T.; Evans, Michael J.; Kabrhel, James E.; Yee, Lawrence J. – Journal of Chemical Education, 2020
The mechanism maps that guide student instruction in organic chemistry curricula are structural representations of bond-breaking and bond-making events that transform a reactant into a product. For students, these pathways represented by electron pushing formalism (EPF) can be challenging to navigate. For instructors, providing formative feedback…

Cruz, Cole L.; Holmberg-Douglas, Natalie; Onuska, Nicholas P. R.; McManus, Joshua B.; MacKenzie, Ian A.; Hutson, Bryant L.; Eskew, Nita A.; Nicewicz, David A. – Journal of Chemical Education, 2020
Despite the recognized effectiveness of course-based undergraduate research experiences (CUREs), there are few examples of the development of a CURE-based course in a large-enrollment undergraduate organic chemistry laboratory. Herein, we describe the development and implementation of a series of undergraduate laboratory experiments centered…

Graulich, Nicole; Hedtrich, Sebastian; Harzenetter, René – Chemistry Education Research and Practice, 2019
Learning to interpret organic structures not as an arrangement of lines and letters but, rather, as a representation of chemical entities is a challenge in organic chemistry. To successfully deal with the variety of molecules or mechanistic representations, a learner needs to understand how a representation depicts domain-specific information.…
