This investigation aims at understanding the identity construction of a developing language teacher, as she takes up practitioner research as part of a pre-requisite for her academic work in a teacher development course. The teacher and I worked collaboratively to understand both the process of becoming a practitioner researcher and our involvement in it. The primary data of the study was generated through research interviews with an exploratory focus to understand the reflection process. The development of hybridity in Exploratory Practice enabled the data generated to constitute work for understanding for both practitioners intriguing puzzles. In the light of Interactional Sociolinguistics, the analysis concentrated on the (re)creation of the developing teacher s research trajectory, as well as the (re)construction of her exploratory identity. The discursive production of explanations and one chronicle in the form of stories was analyzed based on the coherence systems present in them. Along with the reflective trajectory of her stories, the teacher was discursively becoming a new member of the Exploratory Practice Community. It is important to highlight that the analysis did not only focus on the teacher s discourse actions, but also on mine; especially, as I was becoming more senior in this community and developing as a practitioner researcher. Practitioner research based on the inclusive principles of Exploratory Practice has provided opportunities for both practitioners to gain deeper understandings of the process of becoming researchers.
