Aspectos epistemológicos a luz da teoria antropológica do didático subjacentes ao tema transformação linear
(Universidade Federal do Pará, 2017-09) MATOS, Fernando Cardoso de; PEREIRA, José Carlos de Souza; NUNES, José Messildo Viana; GUERRA, Renato Borges
Our purpose in this article was to reveal the epistemological aspects in the light of the anthropological theory of the Didactics are underlying the theme linear transformation in the textbook adopted for the teaching of Linear Algebra at the Federal Institute of Pará, revealing evidence of the dominant epistemological model, analyzing two types of tasks. The analysis of the didactic book is a reference for the elaboration of conjectures regarding the type of teaching that is being developed of a certain knowledge, in a certain institution. The Theory helped us to discuss Mathematical Organization and Didactics of the book in terms of the gender of tasks and task types, techniques and justifications of the rationale of mathematical object linear transformation. The reason for being to teach this object is given by the direct application of the definition, because the students should ask themselves when reading the proposals of the tasks enunciated by the authors, so that and why to study this subject? Some tasks are solved with the contents seen in high school, as a function as technology, not making it clear to the reader that it is a transformation from one vector space to another. We conclude that in the types of tasks discussed it was possible to give evidence of the dominant epistemological model, which we consider the direct use of the definition of linear transformation.

A educação á distância no processo de transposição de praxeologicas didáticas
(Universidade Federal do Pará, 2013-04) ARAUJO, Iza Helena Travassos Ferraz de; GUERRA, Renato Borges
This paper deals with the praxeologies of the subjects - professors in formation and educators - that they had lived deeply the process of formation of professors of Mathematics in the distance education modality. The theoretical support adopted for the analyses was the Anthropological Theory of the Didactic and the methodology of investigation used was of the qualitative type with an ethnographic boarding. The gotten results point to a transposition of praxeologies in the distance education for actual education.

Tarefas fundamentais no fazer matemático escolar: organização matemática para o ensino da geometria analítica
(Universidade Federal do Pará, 2013-04) GUERRA, Renato Borges; ANDRADE, Roberto Carlos Dantas
This 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.
