Análise de narrativas praxeológicas de conexões entre aritmética e álgebra
(Universidade Federal do Pará, 2017-09) PEREIRA, José Carlos de Souza; SILVA, Francisco Hermes Santos da; NUNES, José Messildo Viana
This article is the product of an autobiographical narrative study, which shows an analysis of the praxeologies of the first author, in the context of his professional development as a mathematics teacher. The focus of the analysis is on the various praxeological conflicts that the author experienced during the elaboration and application in the classroom of a didactical proposal for the teaching of polynomial operations in the 7th grade of primary school. In order to analyse his own praxeologies using the didactical proposal he elaborated, the author used Yves Chevallard’s Anthropological Theory of the Didactical (ATD) as the main theoretical reference. The results demonstrated that the personal relations of the first author involved ostensive and non-ostensive types of objects and different tasks and techniques that were either present or not in the didactical proposal he elaborated, revealing past and present praxeologies which composed several different moments of his professional development as a mathematics teacher.

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.

Contribuições do estágio no Clube de Ciências da UFPA para a produção de sentidos subjetivos sobre interdisciplinaridade
(Universidade Federal do Pará, 2018-07) RIBEIRO, Rosineide Almeida; ALVES, José Moysés; RESQUE, Marciléa Serrão
Interdisciplinary science education is still not frequent in our schools. At the Science Club of the Federal University of Pará (CCIUFPA), trainees from different undergraduate courses work in teams and have opportunities to experience the construction of interdisciplinary proposals. Inspired by the Subjectivity Theory of Fernando González Rey, we investigated how the interdisciplinary pedagogical practices are subjectively configured for science teachers, graduated from the CCIUFPA and how they evaluate the contribution of this stage to their current interdisciplinary conceptions and practices. We present four case studies of trainee teachers, whose information was constructed through different instruments. In spite of the uniqueness of each trainee's experience, they considered that the internship at the UFPA Science Club expanded their knowledge of interdisciplinarity, taught them how to face and overcome difficulties to carry out interdisciplinary projects, favored the planning and appreciation of team activities, as well as the recognition of the importance of the motivation of junior partners, the contextualization of contents and dialogue in the classroom. The teachers evaluated that the experiences in the CCIUFPA contributed to the construction of their current teaching practice, and two of them reported carrying out, even with difficulties, the interdisciplinary teaching of science in the school.

Etnofísica e linguagem
(Universidade Federal do Pará, 2015-12) SOUZA, Ednilson Sergio Ramalho de; SILVEIRA, Marisa Rosâni Abreu da
Ethnophysics Knowledge relates to a special class of workers: the craft masters, that is, professionals who have extensive expertise in mobilizing scientific knowledge in fundamentally practical occupations. Our interest is in canoes builders. One question to answer is: how they use language to express their knowledge in science and math? The objective is to investigate the relationship between language and ethnophysics know in the context of building canoes. Specifically we intend: to investigate how the canoes builders express their knowledge about the concept of buoyancy; relate this knowledge to what is learned in textbooks and propose educational guidelines intended to use the ethnophysics in the classroom. We did an ethnographic case study with structured interview a master of a municipality from Pará-Brasil. Initial results show that he uses in his practice the same physical principles of density and buoyancy that would use an engineer or teacher to think about buoyancy; however, the language games mentioned in the interview seem to "mask" the scientific techniques developed in the practice of their craft.

Formação inicial de professores: trajetória de um projeto de inserção social
(Universidade Federal do Pará, 2005-06) GONÇALVES, Terezinha Valim Oliver; ESPÍRITO SANTO, Ariadne Peres
A narrative research focused on Environmental Education project towards reflective teachers trainning. Work lasted for two semesters and came to conclusion when teaching practice were taken to basic schooling institutions in the outskirts of Belém, State of Pará, Brazil. University students in trainning wrote reports indicating which elements were most perceived and valued as well as which meanings were attributed to practices in the classroom. Study observed four categories of analysis: the role of a more experienced professional partner; feelings experienced by those involved in the reseach; meanings attributed to the experience; en developments and difficulties observed throughout. Analysis identified the construction of a new trainning culture; problems in teaching cureer; production of professional knowledge; and reflective attitudes.

Instrução por modelagem de David Hestenes: uma proposta de ciclo de modelagem temático e discussões sobre alfabetização científica
(Universidade Federal do Pará, 2016-07) SOUZA, Ednilson Sergio Ramalho de; ROZAL, Edilene Farias
The pedagogical work with mathematical modeling assumes investigate situations of reality. However, mental models formed from the contact with the experiential world are generally incompatible with the conceptual models. So David Hestenes supports the view that one of the biggest challenges of teaching and learning in science and mathematics is to coordinate conceptual models with mental models, which led to the elaboration of a didactic in mathematical modeling: Modeling Instruction. Our goal is to present a proposal for thematic modeling cycle drawn up in hestenesianos assumptions and discuss possibilities for scientific literacy. The main question was to know how to emerge indicators for scientific literacy for the proposed cycle. This is a bibliographic research in order to identify the available literature contributions on the subject and raise the possibility and challenges for the brazilian teaching science and mathematics. Preliminary results indicate that the proposed modeling cycle can develop indicators for scientific literacy of different natures.

O uso de mapas conceituais como ferramenta metacognitiva no ensino de Química
(Universidade Federal do Pará, 2018-06) TAVARES, Laís Conceição; MÜLLER, Regina Celi Sarkis; FERNANDES, Adriano Caldeira
This study aimed to recommend the use of conceptual maps (CMs) as a metacognitive tool in the teaching-learning process in Chemistry. The research was carried out involving students of the chemistry graduation, during the discipline of theoretical general chemistry II, at Universidade Federal do Pará (UFPA), university campus in Belém. The data were obtained through the collection of CMs elaborated by the students. The analyses were carried out based on the observation of students' contact with the object of study, the way in which the students understood the content and the externalization of the knowledge represented through the maps. The results of this study indicated that through the CMs it is possible to better understand the metacognitive manifestations of the individuals, since the maps make the information more accessible and allow understanding how the students understand the content in study and how they relate the concepts in their cognitive structure. Currently, there is an increasing use of alternative tools for the teaching, including in the field of natural sciences, where they are constants, thus, the use of CMs was quite accepted by students, which contributed significantly to the training of future teachers, demonstrating the importance of this instrument for the teaching-learning process.
