This PH.D. thesis is an attempt to show the beginning, evolution and unfolding of the making of a pedagogical work proposal based on culturally-built knowings in the heart of a traditional community, having as one of its starting points the knowings and doings experienced by dish-making women from Maruanum living in the city of Macapá, State of Amapá, Brazil. This proposal is strongly associated with the need we have to think about the nature of (ethnological)-mathematical knowledge generated by particular communities and about the way such knowledge can be discussed, worked out, and validated in learning environments, regardless of the level of instruction and the constraints imposed by government programs and educational institutions. Among its theoretical foundations are studies on instrumental activities that are typical of the Maruanum ceramics and investigative studies from the point of view of ethnomathematics. Methodological development took place with the application of activities, where traditional and instrumental knowledge observed in the production of ceramics had been adapted for and brought into the school environment , participative observation, as well as data collecting and organization techniques, such as interviews, statements, and audio an visual recordings. Analysis of the data collected focused on the relationship between the data-generating potential and the purpose of this study. Our aim is to make and estimate of the potential contributions from local situations and/or problems it would possibly bring to the formative learning of people involved in the educational processes of these communities, with a view to a spatial and temporal transformation of reality

Contribuição para o Estudo da Aprendizagem da Matemática e da Programação em Comunidades Virtuais de Prática com Foco no Uso de Robots como Mediadores da Aprendizagem O propósito deste estudo, desenvolvido no âmbito de um projeto de investigação que envolveu a utilização de robots na aprendizagem colaborativa da Matemática e da Informática através da Web, é analisar e discutir a noção de participação e o processo de construção do conhecimento em comunidades virtuais de prática. O referido projeto foi desenvolvido em três etapas principais. Na primeira, foram selecionadas as ferramentas de comunicação a serem utilizadas. A segunda etapa envolveu a elaboração e contextualização dos problemas-desafio a serem resolvidos pelos grupos virtuais. A terceira e última etapa do projeto compreendeu o registo e a recolha dos dados e informações obtidos nas reuniões virtuais com grupos de alunos do Ensino Secundário e sua posterior análise, utilizando uma abordagem qualitativa de natureza interpretativa, tendo como referencial teórico a teoria da aprendizagem situada de Lave e Wenger e os conceitos subjacentes às comunidades de prática, objetivando com isto melhor compreender os efeitos das tecnologias sobre tais comunidades, bem como as características da aprendizagem realizada em espaços virtuais. A utilização de robots como mediadores da aprendizagem facilitou a exploração de conceitos abstratos fundamentais relativos às áreas da Matemática e da Informática, permitindo com isto que as tarefas de programação necessárias à resolução dos problemas propostos fizessem mais sentido, pelo facto dos resultados obtidos poderem ser concretizados no mundo real.

Atualmente, o ensino de matemática tem sido configurado, pelos estudantes, como algo de difícil compreensão e pouca utilidade prática, comprometendo diretamente o processo de aprendizagem. Partindo dessa realidade, esse estudo objetiva descrever se existe inovação pedagógica na aprendizagem de matemática mediante o uso de jogos cooperativos. Foi considerado relevante, visto que visa conhecer se há mudança paradigmática em relação ao modo como o processo de aprendizagem dos conteúdos matemáticos é facilitado aos estudantes, com o uso de jogos cooperativos. Esse estudo esteve inserido na concepção de inovação pedagógica conforme delineado por Fino (2011), o qual concebe a inovação como uma mudança paradigmática no modelo tradicional de ensino. Os pressupostos teóricos que embasaram esse estudo foram autores que pesquisam a temática “jogos cooperativos em contexto escolar”. Essa investigação teve abordagem qualitativa do tipo descritiva e inspiração etnográfica realizada durante o período de janeiro a julho de 2014 na Unidade Escolar SESI Petrolina, Pernambuco, Brasil. Participaram 31 sujeitos, sendo 01 professora de matemática e 30 estudantes do 2º ano do Ensino Médio. Os instrumentos utilizados na coleta de dados foram: observação participante, diário de campo, análise de documentos e entrevista aberta, os quais foram analisados a partir da perspectiva de Bardin (2009). Essa investigação apresentou que, apesar dos conteúdos de matemática serem considerados pelos alunos como sendo de difícil compreensão e aprendizagem, quando o professor realiza atividades diferenciadas, tais como, mediante o uso de jogos cooperativos, visando romper com modelo tradicional de ensino, é possível mobilizar e direcionar o desejo do aluno para aprender de forma dinâmica, motivadora, prazerosa e autônoma. Desse modo, consideramos que a prática pedagógica da professora colaboradora objetiva possibilitar momentos de aprendizagens distintas do modelo tradicional por valorizar e promover espaços de aprendizagens onde o aluno possa ser compreendido como construtor do seu processo de aprendizagem.

The following dissertation has as its main advantage the privilege of visualizing the literacy processes through the angle of the functional perspective, which does not see the literary process as a practice solely based on the decoding of alphabetical codes, and then allows for the opening of ample spaces for the allocation of mathematical skills in the realms of the functional literacy. The main object of this study was to investigate which are the contributions that a sequence of activities and of methodologies developed for the teaching of Geometry could provide for a part of the functional literacy process in mathematics of youngsters and adults of EJA, corresponding to the acquisition or to the improvement of skills related to the orientation capacity. The focus of the analyses consisted in the practice of these activities with the young and adult students of an EJA class belonging to a municipal public school of Natal/RN. The legacies of Paulo Freire about the redimensioning of the role of the teacher, of the students, of the knowledge and of their connections within the teaching-learning process, prevailed in the actions of the methodology implemented in the classroom and, especially, in the establishing of dialogic connections with the students, which directed all the observations and analyses regarding the collected information. The results indicated that the composition of articulations between the teaching of mathematics and the exploration of maps and the earth globe enabled the creation of multidisciplinary learning environments and situations, where we could observe, gradually, the development of procedures and attitudes indicating the evolution of space-visual type skills

The present paper is focused on pedagogical practices and continued lecturing formation of High School Mathematic teachers. Knowing the essential importance of the teacher at the educational process since he/she is the mediator on knowledge gathering by the scholars and continued formation meaning on that process, we hereby propose to investigate and compare what Math teachers think about their professional role, the kind of continued formation they receive and their development on teacher s knowledge and doing; to gather and compare what do Math teachers know about young people at public and private schools and their demands and as which find out if they link with the way as their students are taught. To develop our comparative research, we chose a qualitative focus and an investigation of ethnographic type. We took as the subject four Math teachers that work with high school 1st and 2nd grades in public and private schools, morning and afternoon shifts and license titles. The research results reveal differences in structural matter between the spaces, but the comparisons between teacher doings and knowledge reveal that the differences refer to the sort of formation and how often do the teachers search for it. Nevertheless, the reports pointed to continued lecturing formation offering and consistence problems and these reflect on their work and on its basis. The knowledge about youth and adolescence, such as theoric and methodological knowledge that lead their practices, are revealers of teachers difficulties in developing their activities according to the target public and nowadays educational demands

This Study inserts in Mathematical Education & Education that search to investigate the (self) formation of formers that gets graduation e pass to graduate others that get graduation and are formers in Mathematical Education. This Is a qualitative search in a perspective from search-formation.The work is formed of four topics. First topic talks about : The self-formation of formers. Second topic: at way of suppositions theorical-methodological from search. Third topic tells over: The life of a former life. Fouth topic A Station called Ubiratan D´Ambrosio created in his reverence and for build all the Knowledge´s Corpus developed by his studies and searches. It´s in sense of come and go from knowledge created at action by mankind to get finality of Transcendency and Survive. Look for to investigate aspects of academical, professional and personal life where are translated in language, thinking and practices oriented for one know-how holistical and transdiciplined in a reflexion, search and the critical it constitute to be a Professor, Teacher, Searcher and Etnomathematic that confered him the merit in 2005 the Prize Félix Klein, that declared Valente (2007), maximum distinction that can receive someone from Mathematical Education. The results point that the narratives of life´s stories are prominences to one re-direction of teach practical in formation´s courses of Mathematical teachers, opening spaces for what the teachers and particularly of Mathematical thinking and take position about your process of formation to be Formers. The Study also given possibilities to propose fourteen stoppages in Station that are beginnings with direction that emerge from studies and searches about the trajectory of life of Professor Ubiratan D´Ambrosio in perspective of re-signify the formative process in education and Mathematical Education

This is work itself insert in the mathematics education field of the youth and adult education to aim to practitioners of the educational action into the mathematics area performing to with this is teaching kind, adopting to as parameter the Mathematics Molding approach. The motive of the research is to draw up a application proposal of the molding mathematics as teaching and learning geometry alternative in the youth and adult education. The research it develops in three class of the third level (series 5th and 6th) of he youth and adults education in the one school municipal from the Natal outskirts. Its have qualitative nature with participating observation approach, once performing to directly in to research environment as a mathematics teacher of those same classes. We are used questionnaires, lesson notes and analyses of the officials documents as an basis of claim instruments. The results indicates that activity used the mathematic moldings were appreciated the savoir-faire of the student in to knowledge construction process, when search develop to significant learning methods, helping to student build has mathematics connections with other knowledge areas and inside mathematics himself, so much that enlarges your understanding and assist has in your participation in the other socials place, over there propitiate to change in student and teacher posture with relation to mathematic classroom dynamics

La práctica educativa en espacios no formales es un recurso didáctico catalizador de motivación e interese, tanto para alumnos como para los profesores. El crecimiento de los espacios no formales coincide con los cambios recientes en el mundo en los campos sociales, políticos, económicos y culturales. Como una de las consecuencias de esos cambios, tenemos el crecimiento de otras instancias difusoras de conocimientos rompiendo, así, la hegemonía de la escuela. De esa forma, en este trabajo busqué investigar la frecuencia y las formas de utilización de los espacios de educación no formal por profesores de biología, de la enseñanza media, de la Ciudad de Natal (RN). Procuré también, identificar cuales son los espacios de educación no-formal que son utilizados; describir los recursos y las acciones desarrolladas en eses espacios; identificar la existencia o no de interese y la importancia que atribuyen a los espacios para la enseñanza de biología, además de divulgar los espacios utilizados como recursos didácticos. Para alcanzar estos objetivos fueron hechas observaciones de los espacios, aplicados cuestionarios y realizadas entrevistas con los profesores que realizan actividades junto a tales instituciones. Para el análisis de los datos se utilizó tanto el abordaje cuantitativo como cualitativa. Nos basamos en referenciales teóricos de autores que buscan establecer las relaciones entre diferentes modalidades de educación para mejor comprender lo que es la educación no-formal y su trayectoria histórica. Constaté que los profesores utilizan los espacios de educación no-formales, aun la cantidad de visitas al año sea reducida, en virtud de varias dificultades por ellos apuntadas, tales como el transporte, la falta de recursos financieros y de apoyo para viabilizar la visita, entre otros. Verifiqué también que los profesores demostraron un alto interese por los espacios no-formales y apuntaron como principales justificativas para considerarlos importantes para la enseñanza de la biología la posibilidad de establecer conexiones entre la teoría y la practica, además de la complementariedad
