O campo multiplicativo no âmbito institucional: das praxeologias sábias às ensinadas
(Universidade Federal do Pará, 2021-07-01) FERREIRA, Jorge Williams Cunha; NUNES, José Messildo Viana; http://lattes.cnpq.br/5188612973174798; https://orcid.org/0000-0001-9492-4914
The present study aims to analyze the multiplicative conceptual field in the institutional scope, from the wise mathematical praxeologies concerning the referred object of study in question to its didactic transposition in terms of knowledge to teach in the school institution. To this end, in the light of the Conceptual Fields Theory and the Anthropological Theory of the Didactic, we conducted a descriptive analytical study of praxeological organizations inherent in two mathematical works from the academic-scientific literature, the institutional conditions imposed in the curricular design prescribed to basic education in connection with the multiplicative field materialized in the Common National Curricular Base and, finally, an analysis of the diffusion of mathematical objects constituting the multiplicative field in terms of competences/conceptions inherent to the respective praxeological organizations arranged in a collection of mathematics textbooks for the initial years of schooling approved by the National Textbook Plan for the year 2019 for the municipal education system of Belém do Pará. We point to the need of a convergence between nuances related to epistemologicalconceptual aspects of mathematical objects and their relations with cognitive processes between subject and mathematical object in face of the diffusion of didactic-mathematical paxeologies in the school institutional scope.

Geometria analítica nos livros didáticos: uma análise do modelo epistemológicos dominante para o ensino de cônicas no ensino médio
(Universidade Federal do Pará, 2023-08-04) BORGES, Thays de Souza; NUNES, José Messildo Viana; http://lattes.cnpq.br/5188612973174798; https://orcid.org/0000-0001-9492-4914
The objective of this work is to carry out an investigation into high school books from public schools in Pará, in order to identify the dominant epistemological model in exposing the content of analytical geometry, in particular, the study of the geometry of conics, taking it yves chevallard's (1999) anthropological theory of didactics (TAD) and the reference epistemological models developed by Benito (2019), in his doctoral thesis, were used as reference. The adopted methodology was the bibliographical qualitative research. The choice of books was made according to their acquisition in the public network and based on the National Textbook Program (2020). We also seek to carry out a survey of scientific studies, such as those of: Macena (2007), Oliveira (2011), Siqueira (2016) and Jesus (2017), to understand how the learning of conic figures develops in High School . Regarding the performed analyses, we identified that although there is a distinction between the authors' predilection regarding which geometry to work on teaching and learning conics, analytical geometry stands out in relation to synthetic geometry. It is thus concluded that the content on Conics still receives a very algebraic treatment in basic education.
