In this analysis, events from a preservice teacher's internship in a seventh-grade literacy classroom are explored using theories of deconstruction. Deconstruction is activated as both a lens through which to observe and a framework for understanding moments when binaries and other linguistic structures and shortcomings are illuminated as inadequate. In the discussion of deconstruction events and new understandings, the author explains the participant's pushback on the expectation of dividing the personal and professional, her inclusion of voices and perspectives from outside the traditional literary canon, and her rejection of the expectation that preservice teachers will maintain the predetermined limits of the classroom. The paper concludes with implications for future research and teacher education, including a reconsideration of preservice teaching as an opportunity to destabilize inequitable power structures.
