The aim of the present dissertation is to understand the pedagogical practices that stem from the implementation of the 10.639/03 Act at a public school of Nova Iguaçu. The theoretical background to the discussion gathers studies on racial and ethnic relations, school and culture, focusing on Intercultural Education. It is based on a qualitative case study. The methodological methods involved are: document analysis (Political Pedagogical Project of the school, and legal texts supporting the 10.639/03 Act), observations of pedagogical activities during five months (march to july) in 2015, semi-structured interviews with 10 members of the pedagogical team, including 7 teachers and 3 staff. From the data analysis, we observed that the implementation of the 10.639/03 Act both has its limits and opens new possibilities. Books from the juvenile litterature infused with african and afro-brasilian themes, in particular when they present black characters, illustrate means to work on racial and ethnics theme in school, in particular regarding the construction of the racial identity of the students. The teaching resources, the religiosity, the formation of teachers and their conceptions are all seen to be part of the limitations, but they are also the key to new pedagogical processes, new ways to think the practice of pedagogy. In a nutshell, the school that we studied daily includes activities and contents following the themes present in the body of the 10.639/03 Act and its curricular guidelines. It features the Race issue in its Political Pedagogical Project, albeit not as a central theme. Although the pedagogical/cultural practices in the school are focused on the construction of the identity of the children, in the perspective of self-perception of their own identity, that we find paramount, it is also possible to perceive efforts and advances in the direction of better relations between social groups, giving a glimpse of what we could call a truly Intercultural Education.
