This article develops a multimodal model for how claims and evidence work across linguistic, numeric, and visual modes in the professional writing of environmental scientists. I coded and analyzed two reports (Bacey & Barry, 2008;Levine et al., 2005) written by research scientists working for California's Department of Pesticide Regulation (DPR) by applying concepts from studies of argument, genre, and visual representations in science. The claim-evidence patterns show initial and summative claims as well as warrants being presented in linguistic forms; however, supporting evidence (i.e., data and backing) is found in numeric, visual, and linguistic forms. These findings highlight the need to extend Toulmin's understanding of claim-evidence relationships into a more robust multimodal model.
In this essay, we map out four major approaches to the study of writing experiences: (a) worlds apart, (b) literacy in the wild, (c) ecologies and networks, and (d) transfer. We examine how the primary metaphors used in each approach have contributed to our field’s understanding of writing. In focusing on specific dimensions of writing, each framework privileges a different aspect of the writing process, writing development, and/or writers’ context(s). Building on these approaches, we propose the concept of wayfinding to emphasize how writers navigate their own writing development, skills acquisition, and changing knowledge about writing over time. Wayfinding offers a metaphor that resonates with recent work on lifelong learning and meaningful writing. Among other characteristics, wayfinding emphasizes how writers encounter a continuous potentiality in writing and how they navigate unanticipated challenges and opportunities.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
