Ensino de matemática pelo rádio (1950 1970): uma história falada e um documentário didático

This study aimed to describe and analyze aspects of the historical course of teaching Mathematics by Radio Experiences in Rio Grande do Norte, between the decades from 1950 to 1970 in order to organize a documentary (CD-ROM) containing information about Mathematics studied by Radio who have experienced it. In this, we use qualitative research. We seek support in the theoretical framework of cultural history and memory researchers as Certeau (1998), Chartier (1990), Le Goff (2008), Thompson (2002) and Peter Burke (2004). Moreover, we take the elements of oral history. We focus on the teaching of literacy and the primary of the Radio schools in two rural communities - Logradouro and Catolé - who are currently part of the city of Lagoa Salgada (RN) and, with respect to the Junior High School, we stopped in the Course of Madureza at Radio. We used as written sources, especially the documents found in the General Archives of the Archdiocese of Natal (RN) and the employees assigned by the participants of the survey. Our sources come from the oral testimonies of pupils and monitors Lagoa Salgada City, teachers, broadcasters and technicians of Rural Support Service (SAR) Natal (RN). In this study, we identify the geometry Cubação social practices of Lagoa Salgada students. Also identified in the research material, the Global Method with the pedagogy of Paulo Freire, that guided the production of lessons in literacy and primary courses. Content in Mathematics, we find traces of the trend-Empirical activist. In the course of Madureza, there was a tendency formal technique Fiorentini (1995). Finally, as a result of this study, organize and present a documentary (CD-ROM), along with the analysis of this study, containing the history of Mathematics teaching by Radio, from the speech of those who experienced Radio, emphasizing the methodology teaching developed in class, that serves as a reference material for students, professors and researchers.

Alfabetização matemática no contexto ribeirinho: um olhar sobre as classes multisseriadas da realidade amazônica

Esta dissertação, intitulada “Alfabetização matemática no contexto ribeirinho: um olhar sobre as classes multisseriadas da realidade amazônica”, teve como objetivo investigar abordagens teórico-metodológicas para o ensino e aprendizagem de matemática, no âmbito da alfabetização matemática, possíveis de serem estabelecidas em classes multisseriadas de escolas ribeirinhas da realidade amazônica. Nesta pesquisa, a visão de alfabetização matemática foi construída levando em consideração não só as primeiras habilidades de leitura e escrita inicial da linguagem matemática escolar pela criança (DANYLUK, 1997), mas como um caminho para a aprendizagem do homem e mulher no mundo das relações matemáticas, a partir de concepções teóricas de D‟Ambrosio (2002), Domite e Mesquita (2003), Sebastiani Ferreira (1997), I. Mendes (2009) e Freire (2002). A pesquisa foi realizada no município de São Domingos do Capim, Estado do Pará, Brasil, entre outubro de 2010 e agosto de 2011. Na investigação sobre a alfabetização matemática em classes multisseriadas de escolas ribeirinhas, foram realizadas interações com representantes da Secretaria Municipal de Educação, visitas às escolas ribeirinhas multisseriadas, entrevistas com professores deste município. Como instrumentos de construção de dados foram utilizados diário de campo, entrevistas e observações. A análise da pesquisa de campo foi organizada nos seguintes itens: a) As classes multisseriadas e a alfabetização matemática no contexto ribeirinho; b) Recursos didáticos e alfabetização matemática; e, c) Cultura e educação matemática na Amazônia: entre saberes científicos e saberes da tradição. É possível afirmar que a alfabetização matemática expressa no contexto ribeirinho ainda restringe-se as experiências matemáticas referentes estritamente ao currículo escolar sem levar em consideração a riqueza de possibilidades de conhecimentos das experiências dos estudantes em seu contexto diário como localização espacial no deslocamento pelos rios, nos elementos matemáticos envolvidos na comercialização de frutos e pescado, por exemplo.

THE MAPPING IN THE CONTINUING EDUCATION OF TEACHERS: AN EXPERIENCE THROUGH DISTANCE LEARNING

In this work, we show the experience of continuing teacher education in Cartography in the period from 03/11/2009 to 03/11/2010, it was held by the Center for Continuing Education in Mathematics Education, Science and Environment (CECEMCA) - UNESP - Rio Claro, in DL (Distance Learning). This experience was through the extension course set in TelEduc platform. The course was titled Introduction to Cartography and aimed primarily: Present concepts of systematic and thematic mapping and its potential application in teaching practices, increase knowledge in the areas of Geography, Cartography and Environment; Offer alternatives for implementing content mapping in the classroom.

Educação de jovens e adultos: a construção das operações aritméticas em matemática

Working with adult students who attend literacy rooms has been set a challenge for educators, especially with regard to issues of learning mathematics. This work of course completion intention was to investigate the process of construction of arithmetic operations in mathematics from the perspective of the students themselves. Thus specific objectives were to investigate how these students face simple operations that can do this automatically on a daily basis, but not always systematized in the classroom; how these students think and communicate their ideas to the mental operation of the paper record. To this end we chose a qualitative research approach with characteristics of case study, conducted in a room of Youth and Adult participants with three ladies. The data collection occurred through the application of a semi-structured, audio recorded and later transcribed, which issues the verbalization sought and a description of how to give students the learning process of some mathematical content. The results showed that students bring with them skills, cultures and values to the classroom and that these are the basis for understanding the content. The teacher of adult education must take into consideration everything that the student brings to the classroom, their experiences, their history and culture, thus questioning the real world, so they can understand math in a way closer to their daily lives

Windows into Elementary Mathematics:Alternate public images of mathematics and mathematicians

Research on students’ (and teachers’) images of mathematics and mathematicians reveals a number of stereotypical images, most of which are negative. In this paper we present an overview of some these images and stereotypes and consider the questions: (1) how might the image of mathematics and mathematicians be a problem in mathematics education, and (2) what can be done to remedy the situation? Also, we consider an outreach project called Windows into Elementary Mathematics. In this project mathematicians are interviewed about their perspectives on elementary mathematics topics and their interviews are videotaped and are posted online, along with supporting images and interactive content. In this context we consider the questions: (3) what is the Windows project about, and (4) how might it offer an alternate (and perhaps better) image of mathematics and mathematicians? Lastly, we share an example where activities from the project were used in a math-for-teachers course.

An Optimal Control Framework for Resources Management in Agriculture

An optimal control framework to support the management and control of resources in a wide range of problems arising in agriculture is discussed. Lessons extracted from past research on the weed control problem and a survey of a vast body of pertinent literature led to the specification of key requirements to be met by a suitable optimization framework. The proposed layered control structure—including planning, coordination, and execution layers—relies on a set of nested optimization processes of which an “infinite horizon” Model Predictive Control scheme plays a key role in planning and coordination. Some challenges and recent results on the Pontryagin Maximum Principle for infinite horizon optimal control are also discussed.

New readers, new reading skills and meaning: challenges for media and information literacy

Recognizing the importance of developing the information and media literacy in contemporary society, this article discusses the scenario of hybrid languages born on cyberspace, hypertext and the new types of readers who interact with information, now disseminated by digital media. As theoretical references authors such as Lucia Santaella, we develop arguments that present the headquarters of language and thought within a semiotic support. Matrices help to understand the phenomenon of hybrid language in hypertext. Therefore, we emphasize that the development of skills associated with the new reading environments propitiated by the virtual environment requires the understanding of language, which is one of the concepts used within the media and information literacy (MIL) proposal of Unesco, which combines the two concepts and skills of information and media literacy. It is hoped that this article motivate scholars and practitioners of education and information to take responsibility to educate for information environments that arise with new media and technologies, emphasizing the issue of reading and language.

Summarization in Math Class

This action research study of twenty students in my sixth grade mathematics classroom examines the implementation of summarization strategies. Students were taught how to summarize concepts and how to explain their thinking in different ways to the teacher and their peers. Through analysis of students’ summaries of concepts from lessons that I taught, tests scores, and student journals and interviews, I discovered that summarizing mathematical concepts offers students an engaging opportunity to better understand those concepts and render that understanding more visible to the teacher. This analysis suggests that non-traditional summarization, such as verbal and written strategies, and strategies involving movement and discussions, can be useful in mathematics classrooms to improve student understanding, engagement in learning tasks, and as a form of formative assessment.
