This research, which includes all members of a Humanist Movement team in Rio de Janeiro, including the author of this dissertation as a practitioner-researcher, follows the principles of Exploratory Practice (Allwright, 2003). It represents work for understanding how identities are co-constructed while these people perform their function as mentors, who are responsible for the construction of work teams. The data for the analysis have been constructed based on Potentially Exploratory Activities that are part of the team´s daily routine, as well as field diary notes. These data have generated narratives (Bastos, 2005) based on the learning processes that each member represented from their experience. For the analysis, the following concepts were used: a) identity in practice (Wenger, 1998); personal, social and collective identities (Snow, 2001); c) secondary evaluation structure in narratives (Antonio, 2004) and global and theme coherence in the study of narratives (Agar and Hobbs, 1982). The work for understanding has generated the proposed understanding by which the stories presented in this research served as a compensation of the participants´ personal difficulties, besides having the role of strengthening our collective identity while shared. The data also suggests emerging themes such as the question of otherness, the question of internal hierarchy and image as structuring reality (Cobos, 1999), besides highlighting discursive tendencies related to the coherence of the team´s action. The reflection generated through this work enabled participants to raise their awareness regarding their identity construction and to create different participation environments in joint reflection on their attitudes and beliefs.
