Aprendizagem significativa no ensino de ciências : uma proposta de unidade de ensino potencialmente significativa sobre energia e ligações químicas

Abstract

The intention of this study is to present the construction, the use and assessment of a potential meaningful teaching unit in a ninth grade class of science in an elementary school. It aims to approach a meaningful learning. The choice of energy and chemical bonds content in this teaching unit was due to the restructuring of the educational proposal that took place in the municipal school system in the city of Gramado, Rio Grande do Sul, Brazil. The science teachers approached the contributions of physics and chemistry for technological development in a Main Topic entitled Scientific and Technological Development. The research was a qualitative approach, descriptive nature, as to the objectives is descriptive and documentary, participant and research-action on procedures. The teaching unit was organized in six moments with different activities and the analysis of the learning results was developed throughout diagnostic assessment and individual summative evaluation. Reports throughout its implementation and discursive textual analysis were monitored. The potential meaningful teaching unit of this work showed significant results concerning the meaningful learning, as six moments participant students showed not only a predisposition to assimilate the concepts, but the ability to transfer them and apply them in other learning contexts as well.
