This article discusses my (recursive) process of theory building and the relationship between research, teaching, and theory development for graduate students. It shows how graduate students can reshape their conceptual frameworks not only through course work, but also through researching classes they teach. Specifically, while analyzing the intersection of modality, evidence, and argument in my students' writing, I began to adopt Bakhtinian (1981) theory of dialogic voicing and appropriation as a framework through which to approach writing development. I examine the influences of curriculum, policy, citation, and plagiarism on student writing and conclude with discussing the changes in my teaching practices.
