Educação matemática antirracista e decolonialidade: a história que a escola não conta

Abstract

This dissertation aims to promote, based on activities contextualized from the perspective of the education of ethnic-racial relations and in line with Ethnomathematics, an anti-racist education guided by the recognition, confrontation and critical positioning that provide the deconstruction of racist discourses. The theoretical discussion was divided into three subsections. In the first, entitled “Decoloniality”, I presented the deconstruction of facts considered normal in coloniality, with the aim of showing factors of decentralization of European culture. In the subsection called “Ethnomathematics”, I seek to relate the reality of culture to the social environment of the individual, so that he or she can construct mathematical thinking in a process in which there is an encounter between the symbol and the meaning of the studied content. In the third, subsection called “The importance of the black movement in Brazilian education”, I propose the discussion of the struggles and achievements in this long journey to implement affirmative actions and the fight against racism within the school context. As a methodological choice, I opted for a qualitative approach, using action research as a research strategy, and used data analysis to gain an in depth understanding of the phenomenon studied. The research highlights the importance of integrating cultural and mathematical knowledge, with a focus on ethnomathematics, which values African contributions and deconstructs colonial narratives. By exploring concepts such as symmetry and cultural practices, such as the geometric paintings of the Ndebele tribe, the research challenges the Eurocentric view of mathematics. It also emphasizes the need to value non-European cultures and knowledge, recognizing the contribution of black people to the formation of Brazilian society. The research proposes the creation of welcoming spaces in schools to reflect on racism and combat discriminatory attitudes. In addition, it addresses the difficulties faced by the black population in Brazil, such as structural racism in the job market, education, political representation, and police intervention, highlighting the obstacles to equal opportunities.
