| Resumo: | The 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 teacher |
