Abstract
This study uses dialogic theory to understand teacher-writers’ practices across in- and out-of-school contexts. Using case study methods to closely observe and interview a middle school teacher and a high school teacher, as well as analyze their writing, the study identified similarities in the teachers’ appropriations of language, textual practices, and ideologies across contexts. However, each teacher appropriated distinct practices in discipline-specific ways, with one focused onthe literate practices of creative writers and the other focused on the literate practices of online, networked writers. These contrastive examples highlight ways in which teacher-writers’ literate and instructional activities dialogically inform each other in both similar and distinct ways. Ultimately, I make the argument that dialogic perspectives that attend to teachers’ out-of-school practices provide richer, more complex understandings of instructional practice than currently popular conceptions of “best practices” and “value-added” teaching.
