The success of a teacher relies on the nature of the relationships one establishes with his students in their interactions, a particularly important stage, since most impediments to both learning for students and professional development for teachers, are due to relational difficulties. As we will describe in this article, effective relationships help to avoid many conflicts in the educational environment. It is true that we must remain involved, which means not avoiding conflict. In addition, it is natural to have certain reactions (positive or negative), but even more important is to take professional responsibility for relational development and the consequences we manifest in resolving the conflict. Certainly, it is possible and important for new teachers to learn to observe and be observed during their relational development.
