The relations between Communication-Education organise a problematic configuration that allows us to think about present situations, transcending the first conceptualizations that were centered on the school/ media relationship. Social Sciences "classic" topics such us cultural transmission, authority or sociability can be refocused upon this perspective taking into account, on the one hand, discourse issues (its emerging conditions, circulation, reelaboration and censorship) and, on the other hand, the experiences (with institutions, among peers, intergenerational) as two concepts that allow to deepen viewpoints, which are often global in the educational phenomena. The aim of this work is to establish a connection between two research papers in process: the investigation on the ways in which the discourses on cultural authority go through the trajectory of the students training and the discourses -about sexuality, the body and affective relationships- which circulate in the frame of the student sociability. These topics are articulated from a common axis: the public space in which operations of cultural and intergenerational transmissions take place, with processes of reconfiguration of the subjectivities.
