[Between] the Paintings of the Ndebele Houses: [Geo]metries and Ragged Curricula

Resumo

The implementation of Law 10.639/2003 on the Teaching of Afro-Brazilian History and Culture in Schools has demanded from Mathematics Education several studies and problematizations about the nature of the [M]mathematical knowledge present in school curricula. This Law prompts dialogues between different epistemologies, whether of Western origin, Afro-Brazilian origin, or in between these epistemologies, in order to produce new debates that fray the disciplinary logic, neutrality, universality, and uniqueness of Mathematics. Thus, based on the practice of painting houses, which is carried out by women from the Ndebele people of Africa, we can consider the curriculum a place of invention. Objectives: Learning from the Ndebele women, what paintings can emerge? Are curricula invented when Stories and practices of African cultures become the focus of study in Mathematics classes? Design: We are guided by an intervention-research, performing a review of ethnographic investigations on the sociocultural practice of painting Ndebele houses. Environment and participants: The research begins with the subjectivity processes that cross three researchers: two mathematical educators in different stages of life and a philosopher. They are all interested in following different paths with Mathematics Education, Ethnomathematics, Philosophy, and..., which make us professors, determining our conceptions of territory and research. Data collection and analysis: The records and data of this research were produced based on the works of Paulus Gerdes on the paintings of Ndebele houses, as well as other authors of African origin, allowing us to be affected by these productions and question the homogeneous curricular models. Results: With this research, we travel to Africa to find strange the mathematicS practiced by the Ndebele community and to make the mathematics curriculum strange; in this sense, contemplating knowledge at the crossroads of the school curriculum, Law 10.639/2003 and Mathematics, entails producing a notion that is closer to the affective field than the field of meanings. Conclusions: The experience of shifting sociocultural practices to the classroom, such as the sociocultural practice of painting Ndebele houses reveals a curriculum as a place of invention in which mathematicS takes place and composes other curricula capable of painting a different use for Law 10.639/2003 fraying Mathematics' neutrality, universality, and uniqueness, and developing a school curriculum that escapes, leaks, and spreads minor, distinct, and unusual knowledge.
