Análise da temática do café no ensino de Química através dos livros didáticos do PNLD: aplicações e possibilidades

Abstract

The Coffee had its origin in the African continent, in the region of Ethiopia, it is estimated that the Cafa region, which originated the name of Coffee. The coffee cycle was of great importance for the Brazilian economy between the years 1800 to 1930 The cultivation and export of this crop was a real landmark in the history of our country. The historical and technological references allow to identify the possibility of contextualization of the theme and the multidisciplinary possibilities that can be built through some concepts, such as the chemical composition of coffee and its influence of several factors, species, grain type, harvesting, planting conditions, roasting and milling processes. This work aims to investigate the approaches of the "coffee" theme in the textbooks of Chemistry. The methodology of this work was based on exploratory analysis and content analysis. Were analyzed 15 chemistry textbooks participated in the PNLD for the years 2012, 2015 and 2018. Content related to the topic "coffee" was found in 7 of these books, and the presentation form was categorized as: page note, text, activity proposal and thematic framework. It was observed in the books evaluated that the generator theme in question was used only as an example or illustration in the books and not as a proposal for a contextualizing theme.
