Uma sequencia didática para o ensino da resolução da equação do 2. grau : adequação para o uso com professores. 2011. 141 f. Dissertação (Mestrado em Ensino de Ciências Naturais e Matemática) - Universidade Federal do Rio Grande do Norte, Natal, 2011.https://repositorio.ufrn.br/jspui/handle/123456789/16077The present study aims to check whether the use of activities mediated by the History of Mathematics can contribute to improve the understanding of resolution the 2nd degree equation for teachers and undergraduates that reproduce methods of solving such equations, uncritically, without domain of the justifications for their actions. For this, we adapted a didactic sequence with activities that aims to cause a rediscovery of resolutive formula of 2nd degree equation through the method known as cut and paste. Finally, we presented the activity module containing the didactic sequence used during the study, as suggestion for use in the classroom, by the math teacherapplication/pdfAcesso AbertoSequência didáticaHistória da MatemáticaMétodo corte e coleEquação do 2º grauDidactic sequenceHistory of MathematicsCut and paste method2nd degree equationmasterThesisCNPQ::CIENCIAS EXATAS E DA TERRA::MATEMATICA
