Communication competence as a sum of social rules that allow the use of grammatical competences; ability to produce and interpret messages; it is a result of the interaction of the parties to some procedural documents. The principles of communication skills must be respected in order to have an effective relationship. The teacher's style defines the verbal-nonverbal predominance in the educational dialogue. In the framework of didactic communication, it cannot be a question of a simple transmission of data, but also of the development of a complex process of generating sustainable, motivated and integrated behaviors, or of changing some attitudes and behaviors of students.
