The construction of the boat hull at Josefa Indigenous Community, from Mura ethnic group, and traditional mathematical knowledge

This paper aims to expose the construction of the boat hull in Josefa Indigenous Community, from Mura ethnic group, aiming to highlight traditional mathematical processes that simultaneously integrate non-indigenous techniques, shaped throughout the historical period that marked and continues to mark indigenous interactions with non-indigenous peoples. This qualitative research is proposed from an autoethnographic perspective, as data is produced by the researcher and their relatives, utilizing photography as a methodological tool. The hull construction is significant as it values Mura culture, affirming their indigenous identity, particularly in promoting the resilience of their cosmology. The proposal materializes as an opportunity to understand the mathematical knowledge produced in the Amazonian region, contributing to new epistemological approaches within the context of Amazonian Mathematics Education.
