Resumo: This dissertation is the result of a survey conducted in the city of Tabatinga, interior of the State of Amazonas, located in the triple border Brazil, Colombia and Peru. If addressed, in principle, consistent information to the border region, highlighting the educational, political, economic and social relations between the countries. In addition, the study highlighted the implementation of the Federal Institutes, created by Law 11.892/08, and the operation since its installation in the city of Tabatinga. Its general objective is to understand the perception of the school community about the Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Amazonas (IFAM) - campus Tabatinga, weaving an analysis guided the views of internal and external students at the Institute. At first, the focus of the work focused on the presentation of the IFAM campus Tabatinga to tabatinguense school community, considering the offer of vocational technical education to the population. In the second phase, the research highlighted the perception of the school community about the training at the Federal Institute, established in the municipality. The proposal was developed through an exploratory research, with qualitative and quantitative approaches, and using the literature research, document and case study. As data collection instruments were used participant observation and questionnaires. So with the analysis of the study, we believe that the reality experienced by the school community of Tabatinga, and the prospects of these students make up aspects that enable discussion and planning strategies capable of enhancing positive actions for the educational development process, also remedying the obstacles that hinder local growth, guiding the defining issues of the direction of the institution and the region.

Abordou-se, a princ?pio, informa??es relativas ? regi?o fronteiri?a, destacando as rela??es educacionais, pol?ticas, econ?micas e sociais entre os pa?ses. Al?m disso, o estudo ressaltou a implanta??o dos Institutos Federais, criados atrav?s da Lei 11.892/08, e a atua??o do IFAM desde sua instala??o na cidade de Tabatinga. Teve como objetivo geral a compreens?o da percep??o da comunidade escolar sobre o Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Amazonas (IFAM) campus Tabatinga, tecendo uma an?lise pautada nas vis?es de alunos internos e externos ao Instituto. No primeiro momento, o foco do trabalho concentrou-se na apresenta??o do IFAM campus Tabatinga ? comunidade escolar tabatinguense, considerando a oferta da educa??o t?cnica profissional ? popula??o. No segundo momento, a pesquisa destacou a percep??o da comunidade escolar quanto ? forma??o no Instituto Federal, implantado no munic?pio. A proposta foi desenvolvida atrav?s de uma pesquisa explorat?ria com abordagens qualitativa e quantitativa, utilizando-se a investiga??o bibliogr?fica, documental e o estudo de caso. Como instrumentos de coleta de dados foram empregados a observa??o participante e o uso de question?rios. Assim, atrav?s da an?lise do estudo, considerou-se que a realidade vivenciada pela comunidade escolar de Tabatinga, bem como as perspectivas desses estudantes, comp?e aspectos que possibilitam a discuss?o e o planejamento de estrat?gias capazes de intensificar a??es positivas em prol do processo de evolu??o educacional, sanando tamb?m os entraves que dificultam o crescimento local, norteando as quest?es definidoras dos rumos da institui??o e da regi?o.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2018-09-21T17:32:56Z No. of bitstreams: 1 2016 - Luziray Barbosa Gra?a.pdf: 2757117 bytes, checksum: 08740a232f56f689a76ce5383647386f (MD5)Made available in DSpace on 2018-09-21T17:32:56Z (GMT).
