The educational style of teacher is reconfigured in the Romanian postmodernism developed in the absence of postmodernity. Genuine educational communities could contribute to set the Romanian educational system to the sustainable growth. The transformation of school organization from a learning environment to an educational community seems to depend on reconsidering the place and the role of emotional and relational abilities of teachers and on recognising the influence of educational styles of teachers on the group style. The study, part of our doctoral research project regarding the emotional and relational determinants of educational styles of teachers, investigates the strategies of politeness used by teachers and the contribution of positive politeness to the construction of the community. The qualitative sequence of our research was developed in 2015 – 2016 school year, on a sample of 30 primary school teachers from a school in Braşov. Our results confirm that the use of positive strategies of politeness contributes to the community development. The pragmatic approach of our research permits a comprehensive presentation of a contemporary educational community as a constructed social reality.
