摘要:Abstract In a time of digital codification and networking, information flows, ideas, knowledge and cultures in society have intensified in such a way that anyone anywhere can take part in this dynamic from an author's perspective. Schools are struggling to deal with this new culture, marked by horizontality, the so-called digital culture. In this paper we analyze some possible causes of this. We examine public policies to include digital technologies in Brazilian society and also in schools, and the practices developed at the schools participating in the Projeto Um Computador por Aluno (UCA - Project One computer per student), in the states of Bahia and Santa Catarina. The lack of articulation between projects and programs, the fragility of teacher education and making use of the computer a pedagogical tool instead of a communication tool are some of the issues discussed. Articulation between social practices and school practices and the formation of digital culture at Brazilian schools continues to be a challenging task. Keywords: Digital Culture. Education Policy. School Practices.
