Since narrative writing has always been accompanying my personal life and professional career. To inventory, and find the letters written by me to different recipients, in different times and formation degrees, in a movement articulated to the writing of the memorial, based in these letters like memory triggering objects, made us realize, I and my advisor, that the letters could be, at the same time objects of research study, and a rich material in the dialogue between the experiences of school daily life and the historicalpolitical-social contexts. The rereading of the letters and the memorial writing process during the first semester of the Professional Master's Degree overflowed with perspectives of continual (self)biographical narrative writing, a dialogue between memories, narratives and instituting experiences. From the theoretical-methodological point of view, the choice for a (self)biographical narrative research, which articulates the three dimensions throughout the journey: data sources, the register and also the way to produce knowledge, has been delineated as a different research form. where the initial-continuous-permanent reflexive movement shifts the emphasis from the materiality of the sources themselves and of the possible results and/or answers, to the (per)formative course of this dissertation. The paths and (mis)paths of this research-formation, the previous script, as well as the deviations, have caused the reflection in/with a re-signified practice and constituent of the teacher-people that when narratingresearching, researching-narrating, create a dialogical movement of reflection, (per)formation and constitution of identity that reveal and affirm or not, a way of being in teaching.
