Estereoquímica: uma análise do conteúdo didático abordado nos livros do ensino médio e propostas de materiais complementares

Abstract

Traditional teaching is seen as something out of date, the student should no longer be seen as a passive listener of information that the teacher exposes. Faced with the existing technologies that the student has at his disposal, the teacher is no longer the holder of the "knowledge" and has become a facilitator and articulator, this professional profile demanded of him a position of differentiated form of social, political and human development. Since teaching is centered on scientific concepts, contextualization makes it possible to correlate the contents and the reality of the students. The textbooks accompany these changes that are occurring in the current context, as they directly influence the quality of teaching, since their use the students to the content to be explored, besides it the use of didactic resources contributes to the teacher to develop in his classes the participation of the students, as well as abilities, creativity and motivation. The discipline of chemistry, because it is abstract, is repugnant to a good part of the students, who cannot understand it, a fact that relates to methods of teaching aimed at memorizing, that the teacher does not use a more attractive methodology that provides the interaction of the scientific world with the daily life of the student. The understanding of stereochemistry presents considerable difficulty since it requires a three-dimensional view of it. This work aims to analyze how these aspects are being approached in the textbook, to have this approach, and to make a list of complements that facilitate the teaching-learning process.
