A modular and target-group oriented online video library with 48 videos was developed and produced in order to reduce the complexity of an introductory organic chemistry laboratory class. The library comprises three different types of videos: "Tutorials" explaining fundamental laboratory techniques, "Do nots" pointing students…

A continuous flow photopinacol coupling of benzophenone has been developed and implemented in the undergraduate laboratory. This photoreduction was accomplished using 2-propanol as an H atom donor and cosolvent in the reaction. The simple and inexpensive UV light source and flow reactor design (less than $350/photochemical flow system) provide an…

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…

The American Chemical Society (ACS), Division of Chemical Education, Examinations Institute, has been developing content maps to describe comprehensively the undergraduate curriculum aligned to traditional subdisciplines. These content maps have been developed through the combined efforts of many faculty members who teach the targeted courses in…

How well does the undergraduate organic chemistry laboratory curriculum prepare students for academic research, or for a bench job in industry? Running experiments that are more representative of research chemistry has the potential to better equip students for working in a research laboratory, while at the same time giving them insight into a…

An undergraduate organic chemistry experiment has been developed that features asymmetric synthesis of an enantioenriched secondary alcohol, followed by determination of its absolute configuration using the competing enantioselective conversion (CEC) method. Students are given a ketone and an unknown enantiomer of CBS (Corey-Bakshi-Shibata)…

Visualizing molecular conformations and complex compound structures and chemical transformations in 3D is one of the most difficult tasks for undergraduate chemistry students. Modern computational technologies have revolutionized every aspect of our lives, including education. As a result, many researchers and educators are working on enhancing…

In this paper, we describe a study on tasks following the construct of school-related content knowledge. We know from previous studies that such tasks were rated by the preservice chemistry teachers as important for their future profession. Those studies were conducted in a traditional course on organic chemistry which was organized around…

Teaching organic chemistry requires supporting learning strategies that meaningfully engage students with the challenging concepts and advanced problem-solving skills needed to be successful. Such meaningful learning experiences should encourage students to actively choose to incorporate new concepts into their existing knowledge frameworks by…

This paper reports on the relationship between the pre-service teachers' enacted Topic Specific Pedagogical Content Knowledge (eTSPCK) observable in the classroom teaching of Organic Chemistry and learner achievement in the topic. The study employed a mixed-methods research design with a sample of 17 pre-service teachers (PSTs). The PSTs were…

Understanding ongoing chemical processes in the laboratory requires constant shifting between different representational levels--the macroscopic, submicroscopic, and symbolic levels--and analysis of the various mechanistic features of each of these levels. Thus, the ability to explain observations of chemical phenomena with regard to their…

Organosliding is a game adapted from sliding puzzles to teach structural formulas of alkanes to undergraduate students. The goal of this game is to arrange the pieces of the sliding puzzle to form a Kekulé formula of any alkane. The objective is to create as many formulas as students can from one puzzle. The effectiveness of the game was evaluated…

Digital badges are credentials earned via a digital presentation to demonstrate the mastery of a technique. They have been utilized in General Chemistry laboratory courses as an assessment tool and to document students' development of a skill. A digital badge assignment was developed for thin layer chromatography (TLC) and integrated into a…

Polymerization reaction media can have a profound effect on the physical properties of the resultant polymer. This phenomenon is showcased in a new experiment for the organic chemistry and polymer science teaching laboratories wherein the radical copolymerization of biobased [beta]-myrcene and dibutyl itaconate is performed using a nonhazardous…

My thesis work is focused on conceptual and epistemic learning and characterizing the environments in which this learning takes place. Earlier studies conducted by the Stowe group explored how instructional practices, instructional emphasis, and assessment emphasis relate to student outcomes in general and organic chemistry courses. Student…
