Qualidade da água doméstica como tema para o ensino de processos de separação de misturas no ensino fundamental: aproximações com a perspectiva CTS

Abstract

This dissertation presents an action research in the scope of citizen formation, based on the production and use of an educational product. Faced with the need for science education aimed at citizenship and ethical values applied to socio-environmental conflicts where there are influences of scientific and technological factors, this research has as general objective to verify possible potential for citizenship education and the teaching of processes of separation of related mixtures to water treatment, from the application of thematic material produced by the researcher professor. The research has a qualitative nature and the results were organized from approaches to content analysis of textual productions of students and observations and reflections of the researcher teacher, who mediated the process in a dialogic way. The results show some contributions regarding the general objective, however the emergence of adversities and lack of student interaction during the application of thematic material allowed the emergence of new reflections on the planning, elaboration and application of a thematic material in the STS perspective.
