The objective of the present research is to understand the identity construction of two English teachers as they (re)construct their professional life stories. Within the theoretical framework of Applied Linguistics and Critical Applied Linguistics, this study aims at searching, critically and reflectively, for a reinvention of social life and of forms of knowledge production. Based on a qualitative and interpretive research methodology, the data were generated during participatory research conversations that involved the researcher and the two teachers. The teachers themselves selected the parts of the data that they considered more relevant to be to be included and analyzed in this research, thus fostering a reflexive, investigative, and critical practice that pursued moments of deeper understandings. A micro-analysis of the narratives, based on Labov s studies and on Linde s coherence and causality principles, more precisely on this author s common sense system, yielded understandings on how professional choice is socially constructed. The discussion points towards the understanding that the trajectories through which we build our life stories are not necessarily linear and suggests that the main contribution of the present research lies in the proposal of a more innovative, cooperative and hybrid form of work among research participants.
