Ethnomodelling: elaboration of a pedagogical proposal based on the production of cassava flour

Abstract

This research aimed to present how the cassava flour production process can contribute to the development of a pedagogical action for teaching Mathematics, from the perspective of Ethnomodelling. This is qualitative research, using participant observation and interviews through narratives as data production techniques. The research was carried out with a rural producer, who lives in the city of Governador Mangabeira, which belongs to Recôncavo da Bahia. Thus, when analyzing the data produced in the research, the cultural background of the interviewed producer becomes evident, that is, their emic knowledge. Therefore, through the existing relationships between the production of cassava flour and academic Mathematics, verified through rural producer narratives and glocal dialogue, a pedagogical proposal can be developed which addresses the contents of volume, ratio and proportion.
