The theme of this thesis deals with the transition of children from early Childhood Education to Elementary School and with the action of school culture over children s cultures, transforming children as social agents into students as social agents. The research was carried out in a unit of the government (municipal) schools in the city of Três Rios, Rio de Janeiro. The theoreticmethodological fundaments have been created through dialogues with the concepts elaborated especially by Bakhtin, Vigotski, Foucault, Certeau and Sacristán. Each one of these authors contributed in a specific way for the analysis of the questions raised here . The concepts have operated on three plans: on one side we had the conception of language of Bakhtin, which is the main category of analysis of the field data, and Vigotski supplying subsidies for a dialectical thinking about school culture and children`s cultures taken as texts. On another level, we considered Foucault and Certeau`s analysis of power strategies and tactics of resistance found in the practices observed and their influence on the subjectivation of the subjects. Finally, the sociology of childhood and the concept of school culture allowed clarifying elements of the field by placing them in context. To address the transition and the disruptions perceived in this process, the major contributions were set from Moss, Corsaro and Molinari.
