This paper presents findings from a qualitative study on teachers' negotiation of professional identity through talk with colleagues at an urban, public, Midwestern school in the United States. The purpose of the research was to identify discourse strategies the teachers used to negotiate local significances for their professional identities. Analysis and findings demonstrate that the teachers made and recognised identity bids to accomplish the professional identity of teacher as learner, using a range of discourse strategies, including two genres of reflective talk. Implications for our understanding of teachers as knowledge-producers and how this can inform teacher education and education policy are considered.
