The crisis of public spaces implies a closure to the private sphere and, as a consequence, the inanity of the education processes. Space privatization involves the supremacy of the "?????" (house) on the "a???a" (public space), so that the house assumes the role of an enclosed community. The effect of this closure is a weakening of the spatial identification and socialization of preadolescents and the exclusion of differences and relationships with their peers. This break prevents and reduces the autonomous exploration of the space as a place of free expression, the communicative acting, the conflict. This article analyzes the efficacy of the educative role of the quarter and its incidence on the preadolescent development from a sheltered to an open space both through a deep relationship with the environment and an aptitude to explore the external world. The validity of these hypotheses has been proved through a study carried out in three cities.
