Alfabetização científica em ambiente de modelagem matemática
(Universidade Federal de Mato Grosso, 2017-06) SOUZA, Ednilson Sergio Ramalho de; ESPÍRITO SANTO, Adilson Oliveira do
Discussions on Scientific Literacy have been common in Science teaching publications and some Mathematics Education. The literature review shows that few studies address this topic with Mathematical Modeling. Our goal is to discuss Scientific Literacy in Mathematical Modeling environment. For this we seek answers to two main questions: What skills are needed to scientifically literate? and How they emerge in Mathematical Modeling practices? Through literaturereviewwe found that such skills arise in increasingly complex as the transition between the stages of Modeling and as the participation of students in these steps. The study generated a frame of reference that can be consulted by teachers interested in promoting Scientific Literacy in Mathematical Modeling environment.

Aprendizagem em matemática, aprendizagem significativa e neurociência na educação dialogando aproximações teóricas
(Universidade Federal de Mato Grosso, 2017-06) ROZAL, Edilene Farias; SOUZA, Ednilson Sergio Ramalho de; SANTOS, Neuma Teixeira dos
This article aims to present theoretical approaches between Learning in Mathematics, Significant Learning and Neuroscience in Education, highlighting some basic concepts of Neuroscience and weaving theoretical discussions about motivation and timing for the student's learning, according to the stimuli of the His cognitive system, having as methodological reference of teaching the Problem Solving. We believe based on the theoretical frameworks studied, that there is a need to promote a dialogue between Neuroscience and Education, defending a creative dialogue between both and presenting a positive vision of the neuroscientific knowledge in Education, in favor of improving the students' learning. The text highlights information that Neuroscience states that educational attitudes that generate feelings of fear, anxiety, sadness, anger, depression and hopelessness are accompanied by humiliation and these attitudes end up inhibiting the learning process. Our main purpose was to discuss throughreflections in the text that students do not learn if they are not motivated and if the moment is not appropriate for this learning to occur. The article is a bibliographical study and we hope with this work that the understandings between Significant Learning and Neuroscience in Education allow reflections to the teachers so that both are investigated in order to promote the applicability of such theories in the classroom, in our Case, through Problem Solving with the use of the stimuli of the cognitive system for learning.

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.

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.
