UMA LEITURA SOBRE AS ORIGENS DO MOVIMENTO DA MATEMÁTICA MODERNA (MMM) NO BRASIL Antônio Maurício Medeiros Alves Denise Nascimento Silveira Educación Ensino de Matemática Movimento da Matemática Moderna A partir do final dos anos de 1950, diferentes debates sobre a necessária renovação do ensino da Matemática, nos diferentes níveis de ensino, ocuparam professores, pedagogos e outros sujeitos envolvidos com a educação, no Brasil e no mundo. Tais debates desencadearam um movimento que no Brasil ficou conhecido como Movimento da Matemática Moderna (MMM). O MMM tem sido temática de diferentes estudosde pesquisadores que têm, como foco, as mudanças ocorridas na disciplina de Matemática. Esse texto procura contribuir para a superação da representação de “importação” de um modelo imposto, pois os elementos aqui problematizados indicam que, na verdade, a adesão ao MMM no Brasil se deu pelo convencimento da maioria dos professores de que havia necessidade de uma reforma para superação dos problemas enfrentados no ensino dessa disciplina e de que a proposta da Matemática Moderna, com base na aproximação dos estudos do GrupoBourbaki aos estudos da psicologia, poderia ser um meio para isso. 2016 artículo científico 2448-0215 https://www.redalyc.org/articulo.oa?id=672770873001 pt http://www.redalyc.org/revista.oa?id=6727 Revista Tópicos Educacionais application/pdf Universidade Federal de Pernambuco Revista Tópicos Educacionais (Brasil) Num.2 Vol.22
