摘要:Injustices Cognitive Research: giving new meaning to the of cognition, learning and knowledge in the school routine, which we have been developing since January 2008, at the Municipal SchoolAna Nery - SME-D, de Caxias / RJ, seeks to investigate the production of knowledge about reading and writing by children of the the working classes considered by the school as having "learning difficulties". The children with whom we surveyed live on the periphery of the periphery: the neighborhood of Jardim Gramacho -landfill located in the municipality of Duque de Caxias and surrounded by slums. Most families have at the dump their source of income. We discuss the operative logic of children in their daily relationships, taking for granted the assumption of Boaventura deSousa Santos that social injustice is directly related to "cognitiveinjustice." The use of this concept led us to think in school settings: to what extent the concept of cognition with the school work isimbued with the dynamic tools of cognition, limiting the field of action of teaching practices, it disregards the possibilities of invention and problematization? What emerges when we look forfracturing the discourse of "learning difficulties" and how these can be "read" from the perspective of cognitive injustice? Instigated bythese issues, we investigate the formulation of new possibilities foreducational activities from reviewing school-expansion of the concept of cognition, linking it to a political-epistemologicalperspective founded on the concept of "cognitive injustice."
