The aim of this paper is to explore the identity of the teacher as a dialectical being that is in permanent construction, to identify some obstacles teachers might find in this process while operating in an institutional framework, and the effects these could have upon the teacher and the goals she pursues with her students. By ruling out the idea of identity as an autonomous self that can be constructed with no ties with its context, we propose that identity is dialogical and is built through the relationships we establish with others. This fact situates the relationship between the student and the teacher at the center of pedagogical practices and allows us to establish the ideas of teacher presence and integrity as central elements for the moral development of students. In this context, we identify the excessive institutionalization of the role of the teacher as a cause for the reduction of identity and a defensive retreat to the possible outcomes of being judged by strictly formal criteria, which in turn can hinder the relation between student and teacher and risks possible negative consequences in the moral growth of both.
