We intend to follow in our work the ways and aspects regarding the efficiency of the didactic communication. Communication, both didactic and social, remains an open question for research on the possibilities of achieving a full communication, a communication in which the loss of information should be minimal, and it is a satisfaction for both interlocutors. Didactic communication is not only an activity which sets the relationship between the teaching staff and the student to achieve common goals, it is also a psychosocial process of influencing, through specific languages, of the attitudes, behaviors, beliefs, motivational-affective and volitional components. That is why communicating effectively and expressively with others and with oneself implies: - to inform intelligently and to facilitate the understanding of the transmitted message; - develop students' thinking, affectivity, motivation, will and personality; - to notice attitudes and behavioral manifestations of those you communicate with; - and finally convince those you communicate with.
