"It Gets Me to the Product": How Students Propose Organic Mechanisms

Examining the Impact of Student Use of Multiple Modal Representations in Constructing Arguments in Organic Chemistry Laboratory Classes

“…He also argues that we need to examine the pedagogical practices that help shape the writing activities for students. The need for such research was highlighted by several recent studies in the context of college chemistry (Anderson and Bodner 2008;Bhattacharyya and Bodner 2005). It appeared that students had difficulty in representing physical reality using chemical symbols such as Lewis structures, condensed structure, and reaction mechanisms.…”

“…A study by Sandoval and Millwood (2005) in analyzing how students referred to data rhetorically to make their arguments, found that students' references to specific inscriptions in their arguments often failed to articulate how specific data related to particular claims. Surprisingly, Bhattacharyya and Bodner (2005) found that even graduate students majoring in chemistry who have completed organic chemistry were not able to explain the process that reactants underwent to generate products although they drew successfully chemical mechanisms using curved arrows. It appeared that they had simply reproduced a memorized sequence of events.…”

Changing how data are collected can change what we learn from discipline-based educational research

“…Consider the studies we have undertaken of the process by which both undergraduates [19] and graduate students [20] construct meaning of the "curved arrow" formalism organic chemists use to describe the process by which electrons are thought to flow as bonds are made/broken during the course of a chemical reaction, as shown in Fig. 1.…”

“…If your experience has been anything like mine, you might understand why I have put such a strong emphasis on making changes in my courses with only one goal in mind-helping students "think more like a chemist." In other words, facilitating the process of acculturation that transforms "students" into "practicing chemists" by changing the way they approach problems, such as the design of a synthesis of a complex organic compound [20].…”
