Aprendizagem sobre soluções por meio de atividades experimentais e construção de mapas conceituais Giovana Aparecida Kafer Miriam Inês Marchi Estudios Ambientales Mapas conceituais Atividades experimentais aprendizagem significativa A busca pela melhoria dos processos de ensino e de aprendizagem no componente curricular de química justifica a necessidade d e o professor utilizar diferentes estratégias pedagógicas. Este trabal ho trata de uma experiência com alunos da 2ª série do Ensino Médio, do curso Técnico Integrado ao Nível Médio em Informática do Instituto Federal de Educação, Ciência e Tecnologia Farroupilha - Campus Alegrete, utilizando o laboratório de química como espa ço de investigação. Os experimentos foram realizados para abordar os assuntos de solubilidade e concentração de soluções. Os mapas conceituais aplicados nos períodos pré e pós -atividade tiveram por objetivo verificar o conhecimento dos alunos sobre o tema abordado, comparando -se ambos no desfecho das atividades. A metodologia permitiu perceber a interferência do ensino formal quando se pretende mediar aprendizagens por descoberta e em que medida a experimentação pode tornar a aprendizagem sig nificativa. A p artir das metodologias empregadas, foi possível constatar um crescimento potencial dos conceitos relacionados às soluções, ev idenciando que a metodologia utilizada proporcionou uma aprendizagem significativa. 2016 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467546196050 pt http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.1 Vol.38
