This paper presents a vision of mathematical arguments and demonstrations from a socio-epistemological point of view. It allows us to understand that the arguments used in different settings are different to those of deductive arguments. The presence in classrooms of different types of arguments cannot always be explained using Aristotelian logic. Likewise, the non-appearance of forms based on Aristotelian logic in non-mathematical settings, provides us with the possibility of understanding that, with regards socio-cultural aspects, arguments are constructed in non-academic settings which are transferred by students to school settings, due to the fact that they simultaneously experience both settings.

In this paper the discursive forms of description, exposition, narration and argument are analyzed, besides the gesticulation, that employ university students when they reflect on the mathematical notion of punctual continuity of a real function of real variable. We consider the gestural dimension of the visualization actions from an experimental design based on the socioepistemological approach to the research in Mathematics Education, that estimates to the mathematical knowledge among the students as the cultural product of a series of social practices connected with mathematical notions.

In this paper is presented a theoretical articulation of the notion of "mathematical convention" as knowledge generation process in the framework of the socioepistemologic approximation in Mathematics Education. To achieve this, is done a brief description of the basic notions of the socioepistemologic approximation and are presented the basic evidences that allow to interpret the "mathematical convention" as a generator of knowledge in this framework. Later we are sketched some examples that give evidences of the operation of this notion as constituent process in the construction of the mathematical knowledge. [ABSTRACT FROM AUTHOR]

This paper synthesizes the results of an investigation work (Montiel, 2002) about the didactic system's interaction, when these are carried out in an education scenario at distance. We report, within the socioepistemological framework and empirical evidence, how a derivative learn situation can be develop, taking this (the derivative) like variations successive organization.

This paper discusses the theoretical basis of a didactic proposal. It begins from the consideration that the difficulties in the learning process of mathematics among university students of sciences and engineering areas, not only obey to causes of pedagogical or technical order, but fundamentally, in the way in which the mathematical knowledge is selected, articulated and organized with didactical aims. We considered then, that the determination of "what to teach" and not only "how to teach" positivist classic posture is a didactic problem. This search has allowed us to formulate a reasonable >conjecture: it is possible to reconstruct the didactic discourse of a part of the mathematical analysis taking as a central idea the prediction notion >and its links with the Taylor's serie. In another sense, this hypothesis indicates that it is possible to redesign the curriculum and its didactic discorse around of that, we considered, was indispensable for the genesis of the knowledge. We will consider to the Taylor's serie, its contextual antecedents, motivations, situations, temporary evolutions, presentations on classic texts and possibilities of use, some still unexplored in current texts. The article provided with the theoretical base that sustained a Doctoral research in the field of Physics Didactis in Spain. [ABSTRACT FROM AUTHOR]
