O Sensoriamento Remoto como Ferramenta Didática no Instituto Federal Farroupilha Campus Jaguari-RS Carlos Alberto da Fonseca Pire Cristina Cippolat Limana Estudios Ambientales Educação Ensino Técnico Sensoriamento Remoto Este estudo trata do uso das tecnologias na educação de nível profissional e tecnológico, com ênfase nas ferramentas do sensoriamento remoto. O objetivo geral da pesquisa foi realizar um diagnóstico sobre a utilização de tecnologias do Sensoriamento Remoto ( SR ) , no ensino técnico, junto aos cur sos técnicos em Agricultura, Informática, Vendas, Agroindústria e Administração, cursos esses ofertados pelo Instituto Fed eral Farroupilha Campus Jaguari - RS. Metodologicamente, o estudo iniciou com pesquisa bibliográfica para identificar trabalhos já dese nvolvidos sobre SR na educação Profissional e Tecnológica; após , foram escolhidos o campo de pesquisa e o público - alvo. Depois disso, aplicou - se um questionário composto por duas partes, a primeira parte com a finalidade de identificar e a segunda parte te órica, com perguntas de conhecimentos específicos sobre SR. A etapa seguinte foi a de organizar os dados coletados e confeccionar tabelas e gráficos; a partir desses dados, procedeu - se uma análise argumentati va, a lguns dos resultados obtidos revelaram que a maioria dos alunos é do Curso Técnico em Administração, do sexo feminino e que residem no município de Jaguari - RS . Aproximadamente metade da amostra diz nunca ter ouvido falar em SR, mas afirmam ter interesse nesse assunto e acreditam que o SR possa est ar ligado , de alguma forma , com o seu curso técnico, ressaltando assim, a importância de um trabalho em conjunto com os alunos e professores, que vise abordar os conceitos e teorias sobre o SR conforme a realidade de cada curso. 2015 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467546194013 pt http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.3 Vol.37
