Margens, online, v. 7, n. 8, p. 109-121, abr. 2013. DOI: http://dx.doi.org/10.18542/rmi.v7i8.2750. Disponível em: http://repositorio.ufpa.br/jspui/handle/2011/12782. Acesso em:.1982-5374https://repositorio.ufpa.br/handle/2011/12782This essay is part of a research held at the Scientific and Mathematical Education Institute, in Federal University of Pará (UFPA), in which we make a reflection over the tasks for the study of the Plane Analytical Geometry contained in didatics text books adopted in Highschool (Medium Educational Level) in order to identify the relationship among them aiming to determine more inclusive tasks, called by us as “fundamental tasks” which, related to one another, are the base for the solution of other tasks. And, based on this kind of task, propose a new mathematical organization that may contribute to the teachers’ mathematicaldidatics organization as to allow a “school mathematics practice” characterized by a justified and understandable practice. This is accomplished having the Didatics Antropological Theory as a reference.Acesso Abertohttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Geometria analíticaPraxeologiaTarefas fundamentaisAnlytical geometryPraxiologyFundamental tasksArtigo de Periódico10.18542/rmi.v7i8.2750
