Matem??ticas de formas de vida de agricultores do munic??pio de Santo Ant??nio da Patrulha

A Disserta????o teve como objetivo estudar os jogos de linguagem praticados por agricultores do munic??pio de Santo Ant??nio da Patrulha, ao fazerem medi????es lineares e de superf??cie, examinando suas semelhan??as de fam??lia e tamb??m as semelhan??as que mant??m com os jogos de linguagem da matem??tica escolar. As ferramentas te??ricas do estudo adv??m da Etnomatem??tica em seus entrecruzamentos com as teoriza????es de Michel Foucault e as ideias de Wittgenstein em sua obra Investiga????es Filos??ficas. O material de pesquisa consiste em entrevistas realizadas com duas fam??lias de agricultores, observa????es de um dos agricultores em suas atividades laborais e exame das primeiras certid??es de compra e venda de im??veis do Munic??pio. A an??lise desse material mostrou que marcadores associados ??s condi????es clim??ticas est??o presentes nas pr??ticas de plantar e colher; os agricultores utilizam a unidade "tamina" em suas medi????es lineares e de superf??cie; houve movimentos de resist??ncia no per??odo de imposi????o do sistema m??trico decimal naquele munic??pio do sul do Brasil; a aprendizagem de jogos de linguagem envolvendo o uso da unidade "tamina" ocorre atrav??s da transmiss??o oral e de observa????es; e na forma de vida escolar tais jogos de linguagem n??o eram/s??o transmitidos.This dissertation intends to study the language games used by farmers in the town of Santo Ant??nio da Patrulha when taking linear and surface measurements, by examining family resemblances and also the similarities they have with the language games used in mathematics as a school subject. The theoretical tools in this study stem from Ethnomathematics in its crossings with the theories of Michel Foucault and Wittgensteins ideas presented in his book Philosophical Investigations. The research data consists of interviews with two farming families, one of these farmers observations about his work activities, and the analysis of the first certificates of sale of real property issued in Santo Ant??nio da Patrulha. The analysis of this data suggests that markers associated with climatic conditions are present in the practices of planting and harvesting; farmers use the unit known as tamina in their linear and surface measurements; there were resistance movements during the imposition of the metric system in this town of southern Brazil; language games involving the use of the unit named tamina are learned through oral transmission and observation; and in the form of school life, such language games were /are not taught
