Uma Proposta de ensino contextualizado através da fabricação do sabão como tema gerador

Abstract

Chemical knowledge is extremely fundamental to understand the physical and chemical processes that surround our daily life, to make an option for a quality life, to promote and follow the technological development. However, the construction of critical thinking resulting from meaningful learning has been a challenge for chemistry educators across the country. Studies point to the contextualization of chemical contents as a resource to promote an interrelation between school knowledge and facts / situations present in students' daily life, imparting meaning to school contents, causing students to learn meaningfully. In this perspective, this research was carried out in order to corroborate with the teaching of chemistry and with the general objective of proposing a didactic material that presented a contextualized way of working some fundamental concepts and contents of Chemistry, of soaps and detergents. In order to support and justify the choice of the contextualization approach and the preparation of the didactic material, a research was carried out on the Teaching of Chemistry in the public network and the relation of this with the contexts inherent to the reality of the students. It was verified that the current Chemistry Teaching in the public network is traditional and decontextualized. The results of this research point to the need for changes in the way chemical contents should be taught. The second part of the research consisted precisely in the elaboration of the Didactic Teaching Unit, in order to promote the significant learning of chemical knowledge from the theme of soap and detergent manufacture. Thus, it is hoped that we have contributed to the improvement of Chemistry Teaching, and that this is just the beginning of a great journey.
