A TEORIA ANTROPOLÓGICA DO DIDÁTICO COMO UM REFERENCIAL TEÓRICO DE ANÁLISE DAS PRÁTICAS FORMATIVAS NA LICENCIATURA EM MATEMÁTICA Gladiston dos Anjos Almeida Cintia Aparecida Bento dos Santos Multidisciplinarias (Ciencias Sociales) Práticas formativas didática da matemática licenciatura em matemática teoria antropológica do didático No artigo temos por objetivo enfocar a importância da Teoria Antropológica do Didático como um modelo teórico de análise das atividades matemáticas nas instituições formadoras de professores, e com isso, buscamos conjecturar abertura para se (re)pensar as práticas formativas nos cursos de Licenciatura em Matemática como um projeto educacional, político e social respaldado numa perspectiva antropológica da cognição matemática ao tomarmos o estudo da matemática como uma práxis que envolve a transformação/assimilação e/ou construção/apropriação desse saber. 2016 artículo científico 2176-7912 https://www.redalyc.org/articulo.oa?id=589277828008 pt http://www.redalyc.org/revista.oa?id=5892 Revista NUPEM application/pdf Universidade Estadual do Paraná Revista NUPEM (Brasil) Num.15 Vol.8
