Uma proposta de ensino de fra����es no 6�� ano do ensino fundamental a partir da teoria hist��rico-cultural

This text presents developed in the Graduate Program in Science and Mathematics Education at the Federal University of Uberl��ndia, in which it was intended to answer the question: What are the pedagogical implications for the fractions concept learning for students of the 6th grade of elementary school that the teaching guide activities can provide? The objectives of this research were: a) analyze the possible pedagogical implications for the learning of the fraction's concept for students of the 6th grade of elementary school through guiding teaching activities; b) using the conceptual connections of the fraction to enable students to develop an abstract thought and c) investigate whether guiding teaching activities reflect on 'how to think' and 'how to do' of the student. Five teaching activities have been developed (MOURA, 2002) from the perspective of teaching guiding activity (TGA) and had as object of study the teaching of fractions for students in 6th year of elementary school. They have been prepared and proposed activities in which it was intended to investigate the use of history of mathematics as an aid in learning the conceptual fraction links (CARA��A, 1951) by students. Such activities, for analysis, were organized into episodes and scenes (MOURA, 2004) and discussed how students deal with the measurement of whole quantity (all) and subunits (part); how they represent in verbal or written language. It is hoped that the research is set up as an important contribution to mathematics teaching area and may contribute to the initial and continuing training of mathematics teacher sand the formation of theoretical thinking of elementary school students.

Rede de aprendizagem em rob��tica : uma perspectiva educativa de trabalho com jovens

The present research sought to comprehend what is the development perspective of a collective work of educational robotics with high school students. The work started from the development activities Mathematics Sub Project of PIBID (Programa Institucional de Bolsa de Inicia����o �� Doc��ncia, Institutional Program of Initiation to Teaching Scholarship) in a school network from the state of Minas Gerais. The production process of data of this research was done through the follow up of high school students that participated in workshops robotics at the mentioned public school and were selected to continue the project at the Faculty of Mechanical Engineering in Federal University of Uberl��ndia (UFU). Subsequently, these students were involved in activities related to Robotics championships, elapsed through different spaces in public and private schools of basic education, University and Non-Governmental Organization. The data at the research were registered by photos, videos, field notes, documents produced by the participants and arising from internet like the social media Facebook, questionnaires and, mainly, interviews. At the analysis process of data the followed axes were constituted: Movement Learning Network with Robotics; The Different Roles at the Robotics Events and Experiences in Engineering and Technology. By this axes we understand what is the trajectory of the constitution process of a learning network in educational robotics that we find in expansion and consolidation. In this network the research participants performed different roles which left imprints responsible for their transformation. As a more evident imprint, we detected the robot construction and programming, which as for as they moved their studies forward, they developed the subject autonomy, collaboration, sharing and technological authorship.

As escolas polivalentes do Tri��ngulo Mineiro e Alto Parana��ba (MG): sondagem vocacional no projeto desenvolvimentista civil-militar (1965���1976)

This study has as object eight state vocational schools located in Araguari, Arax��, Frutal, Ituiutaba, Monte Carmelo, Patos de Minas, Uberaba and Uberl��ndia, in Minas Gerais. The period analyzed comprises the years from 1965 to 1976, from the signature of the Agreement 512-11-610-042 beteween the Ministry of Education and Culture (MEC) and the American Agency for International Development (USAID), which started a series of other agreements, and actions ending up with the creation of the Expansion and Improvement of High Schools Program (Programa de Expans��o e Melhoria do Ensino M��dio - PREMEM) and, from this, the Vocational Schools. The upper limit of the study, 1976, was the year when these agreements, known as MEC/USAID agreements ceased. The Vocational Schools were characterized as vocation probing schools, directing the professional formation of the population in general, which would happen a posteriori, turning it shorter and more effective, since the labor market would demand, urgently, capable professionals for an expanding economy. The project of Vocational Schools had a national scope, and foresaw, for its unfolding, the complete substitution of State Schools for the new model, called ���multi-curricula���. The theme Vocational schools was the object of my Master���s degree study, when I focused the State School Guiomar de Freitas Costa, in Uberl��ndia. That study raised questionings and concerns that resulted in the central problem of the thesis presented here: understanding the measure in which such schools integrated the country���s development project ��� mostly in the first half of the military rule ��� and to understand its structure, functionality and efficacyThe development of the study presented here, demanded the use of several sources: 1) specialized literature about the topics presented, i.e., the situation of national education in a temporal analysis, the political, economical and social context, research methodologies, the theory of human capital, vocational teaching, pedagogical trends and practices, agreements MEC-USAID and PREMEM; 2) national, state and county laws related to the discussion: laws of national education directives and basis, decrees and reports stating about the program of technical cooperation between Brazil and the United States of America, the Program of Expansion and Improvement of Teaching (PREMEM), formation of professors, establishment of Vocational Schools and educational planning; 3) documentation of school archives: books of minutes of Collegiate and of faculty and staff, registrar books with final scores, enrolment, visits of inspector, accounting books, punch clock records, student, professor and staff occurrences, inventory, class schedules, school year calendar, school rules, class reports, payment rolls, bills of sales, exchanged mail, personal documentation of professional personnel, documents of land acquisition, blueprints, manuals of PREMEM, didactic materials/resources used in classes, books available in the school library, structured evaluations for follow-up of school processes, pictures of events, texts prepared for special dates, and news from the official newspaper and, finally, 4) national and local press reports, especially from Folha de S��o Paulo, Correio de Arax��, Correio de Uberl��ndia and Lavoura e Com��rcio (Uberaba). The proposition of Vocational schools was conciliate theoretical and practical formation through an active education permeated by technological resources. The contact with knowledge and several practical activities under professional supervision, the student would identify the knowledge area that would interest him the most and his aptitude. This formation in primary school would make way for the vocation studies in high school, which became mandatory by the law 5.692/71, that reformed school education from the previous levels of elementary, middle high and high school. However, the multi-curricula proposal that would be spread to the other public schools in the country ended up succumbing to the model already established. From its ephemeral existence, maybe the Vocational Schools have not reached the more general goals in political, economic and social aspects; however, this study demonstrated that, for the people that, directly or indirectly, had contact with such schools, a legacy of vocational and quality teaching was made, so much so, that forty years after the end of that proposal, they are still remembered.

Estrat��gias de trabalho com blogs no ensino de geometria em turmas de 5�� ano do ensino fundamental

This paper presents a survey conducted through collaborative work, which took place in a suburb school in the city of Uberlandia-MG. The research is characterized as case study and has a qualitative approach. Had the objective to look for different strategies of teaching and learning through the use of technology in pedagogical practice. Regarding the methodology in this research, we analyzed the work with the support of blogs, whose pages were used for student records and discussions directed to the geometry content. The students who were attending the fifth (5th) year of elementary school were invited to participate in this project. However, the research subjects were only those students who accepted the invitation to participate in the study through statement signed by parents. The project was developed with 30 students in the second half of 2014 and another 30 in the first half of 2015. The physical space at school, where most of the project activities were done was at the computer lab. In the process of compiling the data, at school, the following instruments were used: field notes produced by the entire project team, photographs and footage of the activities produced in the computer lab and in classroom (recorded by the research team) questionnaires, interviews, virtual space records: the blogs. The results of this research mainly focused on the analysis of the fifth year student���s productions records in blogs. Regarding the conclusion, the research has shown that blogs, software and differentiated dynamic studies attracted the student���s attention, leaving them mostly instigated by the unknown. Gradually, students built their own knowledge from their mistakes and successes. The entire work process enabled the computer lab to be an environment that is used not just to solving computerized and tedious drills. The blogs production work in groups, developed in students the reading and writing of both the mother language as symbols and mathematical nomenclature. The interaction between students became noticeable throughout the project, since it provided the student���s personal growth, respect, tolerance and mutual cooperation. In this sense, we concluded that the project greatly contributed to the students' literacy process in the mother language, mathematics and computer literacy.

Horta escolar: temas geradores e os momentos pedag��gicos no ensino de ci��ncias

Science application has faced problems in the process of training and cognizant thinking subjects in their actions. Thus, this work is justified in order to reorganize the contents of this area of knowledge. Thus, the research entitled "Plantation School: generating themes and teaching moments in teaching of science" was developed with a group of 6th grade of elementary school, from the planting of vegetables in tires without usefulness, with purpose of building meanings and scientific concepts to students. This work was based on sociointeractionist perspective of Vygotsky (1996, 1998), education for thematic research Freire (1983, 1996) as well as in problem-solving situations identified by the methodology of Pedagogical Moments Delizoicov and Angoti (1992; 2002 ) which together corroborated for the construction of a proposed teaching and learning, curriculum reorganization and significance of scientific concepts. Thus, the project breaks in practice with the linearity of the contents, to develop and analyze themes mediated by pedagogical moments, in order to ascertain the contribution of this methodological resource for the teacher's work, with regard to the understanding of scientific concepts by students. Thus, lesson plans were built based on the study situation "Horta School" and Themes Generators "human interaction with the environment", "photosynthesis", "Ecology and Nutrition of living beings", culminating in the work proposal developed in the classroom. From these themes, the contents were worked through pedagogical moments, which are organized into three stages: questioning, organization / systematization of knowledge and application / contextualization of knowledge. Thus, within each Theme Generator activities were planned which resulted in the involvement of students in learning scientific concepts, such as the issue of sustainability, environmental pollution, nutrition of living beings and the decomposition of organic matter. This work led and motivated student participation in Themes generators, and allows greater interaction between teacher-student and student among his peers, through dialogism established in the classroom, which promoted a more meaningful learning for students.
