Conhecimentos matemáticos na profissão de marceneiro

Abstract

The present work had as objective to identify the mathematical knowledge behind the labor activities of the carpenters. In order to reach these objectives, we are based on the ideals of D'Ambrósio (1997, 2001) on Ethnomathematics, as well as other theorists aligned to this theme, such as Gerdes (1996), Monteiro (2004), Borba e Costa (1996) and based on the National Curricular Common Base. The present study was carried out by means of a qualitative research, with visits and observations in the joinery, as well as the elaborations and applications of interviews, in which two carpenters from the city of Caicó-RN were investigated to investigate the level of knowledge of mathematics. Thus, with the results obtained, we show that the knowledge used by the woodworkers is informal, different from what is learned in the school context.
