In this study, I report on my use of critical autoethnographic narrative (CAN) writing with English language teacher candidates (TCs) in a graduate-level teacher education course. In that iterative, scaffolded writing activity, I coached TCs to construct their teacher identity in narrative and make visible to themselves ideologies dominant in the sociopolitical context of language teaching. Drawing data from my CAN implementation in Spring 2023, I analyze Pamela's (pseudonym) case to address this research question: How does she construct her English language teacher identity in a semester-long CAN writing activity? The qualitative data analysis demonstrates that Pamela's language teacher identity involved: (a) becoming a social justice advocate, (b) grappling with neurodiversity, and (c) positioning language as an evolving local contextualized practice. Based on her positioning of language, she denies ‘one right way’ approach to language use, ‘teaching as correcting errors’ approach, and ‘assessment as gatekeeping’ approach as part of her teacher identity. Pamela's CAN shows that the personal, professional, and political dimensions of language teaching are intricately intertwined in teacher identity, and that teacher identity construction involves tensions of competing ideologies in the sociopolitical context.
