DeCocq, Victoria; Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2019
We report our qualitative study of twenty-four students enrolled in the second-semester of a second-year undergraduate (sophomore-level) organic chemistry course, Organic Two. We asked the research participants to propose the product and electron-pushing mechanism of elementary mechanistic steps in the absence and presence of the corresponding…

Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2014
The skill of proposing mechanisms of reactions using the electron-pushing formalism (EPF) is not only of value to practicing organic chemists but it is also emphasized to students enrolled in organic chemistry courses at all levels. Several research studies in the past decade have documented the difficulties that undergraduate, and even graduate…

Sandi-Urena, Santiago; Cooper, Melanie M.; Gatlin, Todd A.; Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2011
Most educators and scientists would agree that science laboratory instruction has the potential of developing science practices fundamental to achieving scientific literacy. However, there is scant evidence to support that this potential is realized, particularly in tertiary level education. This paper reports qualitative results from a sequential…

Verdan, Andrea M.; Ingallinera, J. Tyler; Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2010
We report our study of chemistry graduate students' beliefs regarding the normative values of their disciplines and their perceptions of the ethical challenges they face as students, teachers, and scientific researchers. Using a phenomenographical lens, we interviewed seven graduate students who had achieved Ph.D. candidacy and at least 3 full…

Kraft, Adam; Strickland, Amanda M.; Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2010
In order to understand how students approach multi-variate problems, we report a study on the cues organic chemistry graduate students perceive from mechanism tasks, and the reasoning processes induced by those cues. We used the think-aloud protocol in interviews with sixteen graduate students as they worked on two types of tasks: one, in which…

Strickland, Amanda M.; Kraft, Adam; Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2010
As part of our investigations into the development of representational competence, we report results from a study in which we elicited sixteen graduate students' expressed mental models of commonly-used terms for describing organic reactions--functional group, nucleophile/electrophile, acid/base--and for diagrams of transformations and their…

Bhattacharyya, Gautam – Chemistry Education Research and Practice, 2008
This paper presents a model of the epistemic development of organic chemists from student to practitioner. Key features of this model suggest that individuals first learn the language of organic chemistry, followed by the heuristics. Deep conceptual understanding of the concepts and models of organic chemistry does not occur until individuals…
