Caracterização e quantificação de resíduos de construção e demolição na Região Autónoma da Madeira

Esta dissertação foi desenvolvida tendo como objetivo principal quantificar e qualificar a produção dos Resíduos de Construção e Demolição (RCD) na Região Autónoma da Madeira (RAM). Estes resíduos são provenientes de atividades de construção civil, nomeadamente de obras de construção, reconstrução, ampliação, alteração, conservação e demolição e da derrocada de edificações. Os RCD devem ser, sempre que possível, reduzidos, reutilizados e/ou reciclados (3 R’s). Caso não seja exequível a aplicação direta em obra de um dos 3 R’s, estes deverão ser encaminhados para um operador de gestão licenciado com o intuito de os valorizar e/ou eliminar. Uma das opções mais usuais de eliminação de resíduos na RAM é a deposição legal em aterro. No entanto, ainda há resíduos que têm como destino a deposição não controlada, causando a degradação geral do ambiente da Região. Neste trabalho foram identificados os vários operadores de gestão de resíduos presentes na Região Autónoma da Madeira e quais os destinos finais de cada resíduo, classificado por código de acordo com a Lista Europeia de Resíduos (LER), segundo a Portaria n.º209/2004, de 3 de março. A informação da quantidade dos resíduos encaminhados para os operadores licenciados é transmitida, anualmente, à Direção Regional do Ordenamento do Território e Ambiente (DROTA), sendo possível determinar a tipologia e a quantidade de resíduos recebidos com respetivo destino final. Foi analisada bibliografia nacional e internacional sobre RCD com o objetivo de selecionar indicadores, em kg/m2 (quantidade de resíduos produzidos por área bruta de construção/demolição), mais ajustados às caraterísticas do edificado regional e respetivos processos construtivos. Da comparação entre os valores estimados de RCD produzidos com a quantidade de resíduos recebidos pelos operadores licenciados na RAM, foi possível estimar as quantidades recicladas e reutilizadas em obra e/ou depositadas ilegalmente. O resíduo estudado mais produzido foi o referente ao código LER 170107. Foi ainda, estimado um intervalo de produção total de RCD para a RAM, situado entre 93 e 507 kg/ano/habitante.

Inovação na aprendizagem de língua portuguesa através dos contos populares

A investigação propõe-se a expor o processo, desenhando as condições e motivações que envolvem a aprendizagem de Língua Portuguesa na educação brasileira. Tais aspectos apresentam-se relevantes na medida em que o maior desafio é de incentivar o despertar para a leitura e escrita nos aprendizes das séries iniciais do Ensino Fundamental de maneira inovadora, rompendo com as práticas pedagógicas tradicionais. A questão que norteia a investigação é a seguinte: é inovadora a prática pedagógica baseada em contos populares? Para tanto, utilizou-se a literatura existente relacionada à Inovação Pedagógica e aos contos populares. Como suporte teórico, partiu-se desse ponto para melhor compreensão tanto da linha de pesquisa como do objeto de estudo, contribuindo para o enriquecimento do conhecimento não só no meio acadêmico como também para a sociedade como um todo. O objetivo deste estudo é descrever, interpretar e analisar o projeto em andamento “Ler e Escrever: contos populares, um ponto a mais na aprendizagem de Língua Portuguesa”. Isso será realizado a partir dos aprendizes e do professor polivalente, no momento em que se envolvem com a prática pedagógica baseada em contos populares, no ensino-aprendizagem de leitura e escrita de Língua Portuguesa, na norma-padrão, nas séries iniciais do Ensino Fundamental. Esta pesquisa justifica-se por oferecer uma contribuição original ao campo da Inovação Pedagógica através da investigação do referido projeto em andamento, pioneiro no município de Paudalho (Pernambuco, Brasil). Tal projeto é desenvolvido na Escola Municipal Paulo VI, especificamente a sala de aula de 3º ano do 1º ciclo do Ensino Fundamental. O trabalho de campo se deu sob a ótica da abordagem etnográfica. Os instrumentos incluíram as técnicas: observação participante, entrevista não estruturada, análise de documentos oficiais e pessoais e todos os registros feitos no diário de campo. Diante do exposto, a prática pedagógica baseada em contos populares se materializa em caráter inovador.

Da leitura da poesia à poesia da leitura: a contribuição da poesia para o Ensino Médio

La poésie occupe, à l école, une place réduite et, la plupart du temps, est reléguée à des dates commémoratives ou, quand utilisée, sert de pretexte à l étude de la grammaire et du vocabulaire. Cette thèse a comme objectif de réfléchir sur l importance de l enseignement de La littérature, et plus spécialement, celui de la poésie dans l enseignement secondaire. A comme principal objectif de montrer la place de la poésie dans l'enseignement secondairepour la formation socio-linguistique, cognitive et affective dês élèves. De plus, tente de démystifier l' idée qu'il est impossible de lire de La littérature et, en particuler, de la poésie, avec des adolescents.Il s agit de proposer des projets afin de travailler de manière adéquate la lecture de poésies en salle de classe par le biais de stratégies productives de lectures littéraires comme celles qui promeuvent la rencontre entre le lecteur et le texte. Pour cela, nous avons réalisé une expérience dans une école publique de l état Du Rio Grande do Norte, dans la commune de Natal, avec des élèves adolescents âgés de 14 à 18 ans. L' expérience a consisté en douze cours de lecture de poésies. Nous avons utilisé, comme instruments de collectes de données, des entrevues, des cahiers de classe et des questionnaires. Les références théoriques adoptées consistent en une bibliographie qui fait référence aux études d esthétique de La réception et de la coopération interprétative comme l ont formulées Jauss (1979), Iser (1996) et Eco (2002); la conception de lecteur et le processus de lecture selon Smith (1989); le socio-interactionnisme de Vigotski (1999; 2000); la médiation (lecture par degré ou scaffolding), de Graves et Graves (1995); la psychologie de l adolescence de Becker (1999), Carvajal (2001) e Gutierra(2003). Les résultats montrent l importance de la présence du médiateur dans La formation du lecteur, sachant qu en plus de contribuer et de potentialiser l intéraction entre le texte et le lecteur, l adhésion des élèves est améliorée. L expérience de vivre la poésie en salle de classe avec dês adolescents sujets de cette recherche, a prouvé qu il est possible, dans l enseignement secondaire, et malgré les difficultés, de réaliser um travail avec la poésie

Tramas do impedimento: os sentidos da desistência entre Alfabetizandos da EJA

For young people and adults that have not yet conquered reading and writing, being literate is the most important thing in life , a dream . Scholarly learning for them is like hegemonic knowledge in contemporary literate society. Thus, for them to get into school is to be able to have such knowledge and, through it, feel inserted into this society. However, along this process of learning, they start to drop out, little by little, statistically increasing the number of people who give up on young people and adult education Eja, as well as slowly reducing the contingent of illiteracy in the country. With this reality as a starting point, we question the concrete and symbolic reasons or motives that lead to a dropping out of the literacy classes at Eja. To do so, we have established, as the object of our study, the feelings of giving up among those involved in young people and adult literacy training. To understand such feelings is our purpose in this investigation. The theory of Social Representations (MOSCOVICI, 1978, 2004) was the theoretical-methodological option for subsidizing data search, analyses and interpretation, making us perceive the significance of the object of this study for these individuals. The gathering of such symbolic content involved the use of semi-structured interviews with eleven drop-outs and ten students who had repeated this modality of teaching in public schools in Natal, RN, during the 2006 school year. From the thematic and categorical analyses (BARDIN, 1977), we identified elements that gave support to some themes. Later, these themes led to three categories, suggesting that feelings associated with dropping out were based on the following: learning difficulties because they did not understand the contents; having their lack of knowledge exposed, thus bringing forth feelings of shame, humiliation, and embarrassment for not knowing how to read and write at a mature age; work, tiredness and sickness. The students who manage to remain in school are those who force themselves to live with the feelings of maladaptation and those who develop a sense of adaptation the other way round to the institution, that is, acceptance of institutional failures and omissions

Retratos, imagens, letras e numeros colados nas paredes:representaçãoes sociais de escola para ribeirinhos dos rios Môa e Azul - Acre

Remote Communities. Absence of artifacts and minimization of the exacerbated consumption of modernity. The desire which spread beyond what reality can provide. Expressions like this are present in this paper which focus in the social representations of school built by residents who live at the riversides of Môa and Azul Rivers, in Mâncio Lima, Acre State. To do so, we used the methodological contribution of the semi-structured interview, observation of the place while a natural inhabitant of the region, and also photos analyses of local reality. A key feature of the riverside homes is the glued paper on the walls of houses forming a panel set of portraits, pictures, letters and numbers for all appreciated. Regardless of whether or not read, there is admiration for the color of the images, the layout of the letters, and the things of the city awakening the desire to obtain school knowledge. The resident of this Amazon region maintains a close relationship between thinking, acting and feeling living harmonically with nature that connects them to the ideal landscape which is revisited by the graphic material that attracts wondering what exists beyond the shores of the river, beyond the horizon of green forests. It is a life entirely accomplished by the imaginary where exist a framed landscape merged and confused by the real and the supernatural, in which men and gods walk together by the forest, sailing by the rivers and seek a possible aesthetic between the real and ideal. The Theory of Social Representations spread by Serge Moscovici (2005) and Jodelet (2001) guided our gaze on the understanding what the school is and its representation to the riversides, as well to reveal the relation they practice with the knowledge that is spread by the mystification and the knowledge that is practice daily. Based in Bardin s thematic analysis (2004) we tried to raise such contents combining them in five analysis categories

Histórias de leituras e de leitores: práticas e representações de leitura em narrativas de professores de diferentes disciplinas escolares

Nous avons pris comme point de départ le préssuposé que en exerçant ses practiques de lecture en salle de classe, les professeurs récuperent des signes de ses expériences socioculturelles par rapport à la lecture, construites au long de ses trajectoires. Indépendemment de sa discipline scolaire, la mémoire de ces expériences interviennent certainement, de manière positive ou négative, dans la médiation de la formation de l élève lecteur. C est donc, par l articulation entre les perspectives de ses études qui parlent sur l histoire de la lecture, narratives (auto)biographiques et formation du professeur que je prétends récupérer et reconstruire, par les narratives de lectures racontées par les professeurs de différentes disciplines scolaires, les processus d appropriation de la lecture en considérant ses tactiques d accès et d utilisation des matériels écrits en circulation dans les groupes sociaux auxquels ils appartennaient. Pour ça ce travail s inquérit : Quels models de lectures émergent dans les narratives de professeurs de différentes disciplines scolaires ? Comment se manifestent-elles les représentations sur sa performance pour la formation de l élève lecteur ? L objectif central est d inférer les rapports existants entre des expériences de lecture et la médiation dans la formation de lecteurs. Douze professeurs de l éducation de base des écoles de la ville de Belém y ont participé. Le corpus est constitué par les transcriptions de deux genres d instruments: douze interviews narratives et deux groupes de débats. Les analyses montrent deux grandes fases de la rencontre avec la lecture : une antérieure à l école et l autre à partir de l école. Ces fases montrent des pratiques et des représentations de lecture hétérogènes différenciés par rapport à ses aspects fonctionnaux. Elles revellent encore que la formation du lecteur professeur et élève se lie, d abord, à la constitution culturelle de l homme, marquée, fondamentalement, par son interlocution avec l autre. La famille, l école et le lieu de travail se présentent comme des espaces qui impriment des marques profondes dans le rapport avec la lecture. Malgré ça, le même matériel écrit, un fois mis en scène le lu dans ces espaces n ont pas de significat coincidents pour les différentes personnes qui s en approprient. Cette raison montre la possibilité de la construction d une histoire de la lecture, basée pas exclusivement à la description des matériels lus pendant le cours de leurs vies, mais surtout, sur les indicateurs de ses différentes manières de lire. Cette trajectoire exerce de cette façon une forte influence sur la prise de décision et les manifestations du travail du professeur en situation de salle de classe. Comme ça on peut conclure, premièrement, que les représentations et pratiques de lecture se sont constitués et se sont (re)configurés dans des différentes formes, concepts, temps et espaces, dans un entrecroisement de différents discours. Deuxièmement que la reflexion sur les mémoires de lecture a resulté un nouveau regard des participants sur son travail de professeur et a confirmé l hipothèse selon laquelle la production des narratives autoréférencées offre, à qui les narre, la possibilité de transformation des représentations du sujet avec lui-même, avec l autre et avec le monde, ce qui démontre l importance de la recherche (auto)biographique comme méthode d investigation en éducation et sa contribuition pour la formation des formateurs de lecteurs dans des différents domaines de la connaissance , comme territoires constitutifs du sujet et de ses pratiques sociales, à l école et ailleurs

O professor e sua formação linguística: uma interlocução teoria-prática

The work in screen constitutes a study of entitled doutoramento THE teacher and your linguistic formation: a dialogue teoria-prática. In him, the researcher, discoursing on subjects that involve the teaching-learning of the verbal language, it focalizes the importance of the linguistic formation for professionals that act in the years you begin of the Fundamental Education. In that perspective, lens to analyze the interrelações among them you know about the teachers, referring to the language (verbal), mobilized in the process teaching-learning of the production of texts written by the students, enrolled in the years you begin of the fundamental teaching. For so much, it developed a research Colaborativa, of qualitative nature, with four partícipes, being three of them teachers of the empiric field, EETB (pointed school for the " Prova Brasil " (2005) as among the ten Brazilian schools with the worst index of revenue discente in the abilities to read, to write and to interpret) and the other (researcher) educational of UERN. The research made use of several methodological procedures, among which stand out: questionnaire, glimpses, reflexive sessions and cycles of reflexive studies, among others. These specific of the Methodology of the Elaboration Conceptual Ferreiriana, adopted in the process of (re)elaboration, for the partícipes of the language concepts, text, textual gender, spoken language and written language. With relationship to the analytic procedures, those were based in contributions of the theory of the formation of concepts, of the Applied Linguistics and of the archaeology of the elect concepts. The results appear that the process of linguistic formation, established through the research colaborativa and of the methodology of the elaboration conceptual ferreiriana, uniting knowledge of the areas of the Education and of the Language, it was productive and he/she reveals a narrow relationship among the acquired knowledge for the partícipes, the (re)organization of the process teachinglearning of the language and the improvement of the productions written by the students of those educational ones

O ato pedagógico como ato gnosiológico em Paulo Freire ensinar como uma aventura criadora

La presente tesis doctoral tiene como objeto de estudio la visión epistemológica de Paulo Freire y como punto central su comprensión del acto pedagógico como un acto gnoseológico e sus consecuencias para la praxis docente. La tesis original afirma, que en la obra de Freire hay una comprensión sobre el conocimiento ubicando el acto pedagógico como una situación gnoseológica, comprensión esta, indispensable a una praxis educacional libertadora. Para identificar esa comprensión, la presente investigación de carácter bibliográfica y cualitativa fue realizada a partir de indicaciones del propio Paulo Freire sobre el acto de leer/estudiar y del abordaje hermenéutico de Hans-Georg Gadamer, utilizando el diálogo con los textos del autor, buscando los sentidos capaces de responder a las cuestiones desarrolladas en la tesis. El trabajo presenta, además de una pre-comprensión del tema, los resultados de los ejercicios dialógicos mantenidos con los textos de Freire sobre el conocimiento y la educación como situación gnoseológica. Oportunamente fueron construidos mapas conceptuales de los hallados de la autora, para una mejor visualización espacial del lector, así como de los diálogos con tres estudiosos del pensamiento de Paulo Freire. El pensamiento de Freire sobre el conocimiento y la educación como situación gnoseológica abarca las siguientes dimensiones, aparte de la dimensión epistemológica propiamente dicha: dimensión históricofilosófica; dimensión político-ideológica; dimensión comunicativa y dialógica; dimensión ética y estética; dimensión pedagógico-cultural; y dimensión institucional y de gestión. La comprensión por el educador de esas dimensiones bien como sobre el Ciclo de Enseñar y Aprender pueden contribuir de modo significativo para una praxis docente capaz de recorrer el camino del diálogo problematizador, aquel que puede tornar el acto pedagógico un acto verdaderamente gnoseológico, capaz de auxiliar hombres y mujeres en su proceso de humanización

Cidade e sociabilidades (Principe, Rio Grande do Norte seculo XIX)

Dans ce travail qui a comme thématique ville et éducabilité et comme objet les pédagogies de la ville de Príncipe au XIXème siècle, nous avons pour objectif de problématiser comment la relation entre la ville et les sociabilités constituent les éducabilités dans cette ville de Príncipe au XIXème siècle, à partir d'espaces de propagation d énoncés pédagogiques. Ainsi, nous proposons la thèse qu il existe une pédagogie de la ville de Príncipe au XIXème siècle, vu que le modus vivendi de celle-ci est lié à des sociabilités de diverses instances, la constituant comme investie d'une orientation pédagogique et l'habitant de la cité comme formé dans et par des sociabilités. Le corpus de documents de l'étude de la pédagogie de la ville se compose de sources distinctes et suffisantes. Elles sont: ecclésiastiques, politico-administratives, notariales et judiciaires. Pour l'analyse et l'interprétation de ces sources, l'étude s'est basée sur la méthode indiciaire, permettant de considérer les détails et la conciliation entre la rationalité et la sensibilité. Ce travail s'inscrit dans la dimension de l'histoire culturelle ici entreprise, de conformité avec Roger Chartier et Peter Burke en tant qu étude des processus avec lesquels se construisent des sens, il faut donc la rapprocher à des configurations sociales et conceptuelles d'un temps et d'un espace propres. De cette manière, nous localisons et focalisons le modus vivendi de Príncipe à partir de pratiques sociales et de valeurs de la vie matérielle et des élaborations symboliques qui constituent un ensemble d'apprentissages liés à la relation entre les espaces et les sociabilités, celles-ci étant constituées et constituantes de pédagogies à la ville. Visant les espaces et ses écrits, sociabilités et éducabilités nous comprenons que nous constituons une histoire d éducabilités dans la ville de Principe au XIXème siècle, celle-ci a comme plus grand constructeur la ville et ses composants d'éducation socialisatrice et instructive. En termes conclusifs, penser à la ville et l éducabilité met en valeur que la pédagogie de et dans la ville se laisse lire par les pratiques et les actions propagées aux sociabilités qui, dans l'intersection de la pédagogie de la ville et des éducabilités, se sont (con)figurées comme formatives

A escola rural e o desafio da docência em salas multisseriadas: o caso do seridó norteriograndense

Uno de los principales desafíos colocados a la educación del medio rural está relacionado a la enseñanza de las escuelas rurales con salas multifacéticas. Estas comprehenden alumnos de diferentes comunidades, series, edades, aprendizaje y niveles de conocimientos. Son cursos heterogéneos, que tienen como característica central la diversidad. En muchas regiones rurales de Brasil, la educación escolar es organizada en cursos multifacéticos debido a las grandes distancias entre las comunidades y el bajo número de alumnos en cada serie/año. Es común encontrar a los que están en fase de alfabetización estudiando con quien ya sabe leer y escribir - y todos sobre la orientación de apenas una profesora, que necesita enseñar a partir del contexto y la cultura local. El punto principal a ser tratado en este estudio está relacionado a las prácticas ejercidas en la acción educativa de las profesoras que actúan en escuelas rurales con salas multifacéticas de la región del Seridó do Rio Grande do Norte, precisamente en los municipios de Caicó, Jardim do Seridó y Ouro Branco. Creemos que este es uno de los puntos centrales en la discusión sobre la organización de la educación en el medio rural con fuertes implicaciones para el atendimiento cualificado de la población en condiciones de escolaridad de ese medio. Las contribuciones de Werthein y Bordenave, Calazans, Paiva, Ramalho, Therrien y Damasceno, Leite, Passador, Molina, Arroyo, Nascimento, Hage, además de documentos oficiales del MEC, como cuadernos SECAD, Ley de Directrices y Bases de la Educación Nacional, Directrices Operacionales para la Implantación de la Enseñanza Básica de 9 (nove) años, Proyecto Base del Programa Escuela Activa, entre otros, fundamentaron el análisis sobre la escuela rural y el desafío de la docencia en salas multifacéticas en el contexto del Seridó norteriograndense. El estudio envolvió 24 (veinticuatro) profesoras y 06 (seis) profesionales de la educación que desempeñan sus funciones en los Centros Municipales de Enseñanza Rural (CMER). Los instrumentos de investigación empleados fueron cuestionarios y observaciones aplicados para responder a las siguientes preguntas: ¿cómo se estructura la escuela rural con salas multifacéticas? ¿Cómo las profesoras se posicionan sobre su trabajo en salas multifacéticas esto es, como las concibe en el contexto de la educación rural del Seridó? ¿Qué opinan sobre la formación recibida para actuar en salas multifacéticas? Las profesoras y los/las profesionales de los CMER poseen en general formación superior en pedagogía, sin embargo, presentan limitaciones delante de las situaciones surgidas en el día a día de la sala de clases. El estudio revela que son las deficiencias de las políticas sociales y educacionales de formación docente, el bajo apoyo didáctico-pedagógico, reforzadas por la ausencia de un plano de carrera que dignifique el trabajo docente en ese medio, que generan limitaciones en el desarrollo profesional del magisterio rural, claramente junto a los docentes que actúan en salas multifacéticas en los municipios investigados

Plataforma Robótica de Baixíssimo Custo para Robótica Educacional

Robots are present each time more on several areas of our society, however they are still considered expensive equipments that are restricted to few people. This work con- sists on the development of control techniques and architectures that make possible the construction and programming of low cost robots with low programming and building complexity. One key aspect of the proposed architecture is the use of audio interfaces to control actuators and read sensors, thus allowing the usage of any device that can produce sounds as a control unit of a robot. The work also includes the development of web ba- sed programming environments that allow the usage of computers or mobile phones as control units of the robot, which can be remotely programmed and controlled. The work also includes possible applications of such low cost robotic platform, including mainly its educational usage, which was experimentally validated by teachers and students of seve- ral graduation courses. We also present an analysis of data obtained from interviews done with the students before and after the use of our platform, which confirms its acceptance as a teaching support tool

Desenvolvimento de um ambiente para projeto de controladores fuzzy para dispositivos móveis

Fuzzy intelligent systems are present in a variety of equipment ranging from household appliances to Fuzzy intelligent systems are present in a variety of equipment ranging from household appliances to small devices such as digital cameras and cell phones being used primarily for dealing with the uncertainties in the modeling of real systems. However, commercial implementations of Fuzzy systems are not general purpose and do not have portability to different hardware platforms. Thinking about these issues this work presents the implementation of an open source development environment that consists of a desktop system capable of generate Graphically a general purpose Fuzzy controller and export these parameters for an embedded system with a Fuzzy controller written in Java Platform Micro Edition To (J2ME), whose modular design makes it portable to any mobile device that supports J2ME. Thus, the proposed development platform is capable of generating all the parameters of a Fuzzy controller and export it in XML file, and the code responsible for the control logic that is embedded in the mobile device is able to read this file and start the controller. All the parameters of a Fuzzy controller are configurable using the desktop system, since the membership functions and rule base, even the universe of discourse of the linguistic terms of output variables. This system generates Fuzzy controllers for the interpolation model of Takagi-Sugeno. As the validation process and testing of the proposed solution the Fuzzy controller was embedded on the mobile device Sun SPOT ® and used to control a plant-level Quanser®, and to compare the Fuzzy controller generated by the system with other types of controllers was implemented and embedded in sun spot a PID controller to control the same level plant of Quanser®

Adaptação eletrônica de um leitor mecânico de coto, investigação e desenvolvimento de interface CAD

Due to advances in the manufacturing process of orthopedic prostheses, the need for better quality shape reading techniques (i.e. with less uncertainty) of the residual limb of amputees became a challenge. To overcome these problems means to be able in obtaining accurate geometry information of the limb and, consequently, better manufacturing processes of both transfemural and transtibial prosthetic sockets. The key point for this task is to customize these readings trying to be as faithful as possible to the real profile of each patient. Within this context, firstly two prototype versions (α and β) of a 3D mechanical scanner for reading residual limbs shape based on reverse engineering techniques were designed. Prototype β is an improved version of prototype α, despite remaining working in analogical mode. Both prototypes are capable of producing a CAD representation of the limb via appropriated graphical sheets and were conceived to work purely by mechanical means. The first results were encouraging as they were able to achieve a great decrease concerning the degree of uncertainty of measurements when compared to traditional methods that are very inaccurate and outdated. For instance, it's not unusual to see these archaic methods in action by making use of ordinary home kind measure-tapes for exploring the limb's shape. Although prototype β improved the readings, it still required someone to input the plotted points (i.e. those marked in disk shape graphical sheets) to an academic CAD software called OrtoCAD. This task is performed by manual typing which is time consuming and carries very limited reliability. Furthermore, the number of coordinates obtained from the purely mechanical system is limited to sub-divisions of the graphical sheet (it records a point every 10 degrees with a resolution of one millimeter). These drawbacks were overcome by designing the second release of prototype β in which it was developed an electronic variation of the reading table components now capable of performing an automatic reading (i.e. no human intervention in digital mode). An interface software (i.e. drive) was built to facilitate data transfer. Much better results were obtained meaning less degree of uncertainty (it records a point every 2 degrees with a resolution of 1/10 mm). Additionally, it was proposed an algorithm to convert the CAD geometry, used by OrtoCAD, to an appropriate format and enabling the use of rapid prototyping equipment aiming future automation of the manufacturing process of prosthetic sockets.

O uso da abordagem CTSA para o ensino de energia tendo o desenvolvimento sustentável como eixo temático

In recent decades, humanity has become increasingly concerned with environmental problems. Proofs of this are increasing initiatives in civil society organizations, private institutions and government actions, either local, state or national actions to promote environmental protection. The goal of this research is to contribute to the formation of citizens more aware of their responsibilities to sustainable development issues, simultaneously to their learning of physics in the secondary school. Thus, we have designed a research project that aims to evaluate the effectiveness of the adoption of the concept of sustainable development as a central theme in physics classes in high school. From this goal, we designed, implemented and evaluate lesson plans that aim not only to construct and apply the concept of energy, but also to understand their transformations and conservation law, as well as their processes of production, distribution and consume in the context of physical laws in which it is involved. Then, it was deliberately provided to students, during classes, to read, interpret and produce texts, by this way being able to think and start to have a critical view of the world around him, as well as absorb the energy concept and understand his occurrence in phenomena of nature and in technologies. The approach used for this was that constraining science, technology, society and environment - STSE. This teaching methodology has been applied in the IFRN Ipanguaçu campus, for students of two classes of first year of high school integrated course in agroecology and in technical computing. The survey results show the effectiveness of both methods with respect to the viewpoints of students in relation to the guidelines of sustainable development and the learning of physics content proposed. It is hoped with this dissertation to contribute to the formation of future men and women as citizens environmentally friendly, but also as a source of inspiration for teachers who wish to foster in its students such a critical position about civic education, from their classes

Linguagem matemática: uma proposta de ensino e avaliação da compreensão leitora dos objetos da matemática

This paper discusses aspects related to the mathematical language and its understanding, in particular, by students of final years of elementary school. Accordingly, we aimed to develop a proposal for teaching, substantiated by mathematical modeling activities and reading, which takes advantage of the student of elementary school a better understanding of mathematical language for the content of proportion. We also aim to build / propose parameters for the assessment of reading proficiency of the language of the student in analyzing and modeling process, its ability to develop/improve/enhance this proficiency. For this purpose, we develop a qualitative research, with procedures for an action research whose analysis of the data is configured as Content Analysis. We refer to epistemological and didactic, in the studies: Piaget (1975, 1990), Vygotsky (1991, 2001), Bakhtin (2006), Freire (1974, 1994), Bicudo and Garnica (2006), Smole and Diniz (2001), Barbosa (2001), Burak (1992), Biembengut (2004), Bassanezi (2002), Carrasco (2006), Becker (2010), Zuin and Reyes (2010), among others. We understand that to acquire new knowledge one must learn to read and reading to learn it, this process is essential for the development of reading proficiency of a person. Modeling, in turn, is a process which enables contact with different forms of reading providing elements favorable to the development here mentioned. The evaluation parameters we use to analyze the level of reading proficiency of mathematical language proved to be effective and therefore a valuable tool that allows the teacher an efficient evaluation and whose results can guide you better in the planning and execution of their practice
