Conteúdo equilíbrio químico em livros didáticos para o ensino médio

Abstract

The contents of textbooks organize the curricula for basic education, and have an instructional and educational purpose. The objective was to describe how high school textbooks address the chemical balance content from the criteria of contextualization, interdisciplinarity and experimentation. The nature of the data and procedures used was qualitative. As for the general purpose, it was configured as exploratory research. The method that conducted the techniques and instrument of data collection was the bibliographical research. Four textbooks approved by the National Textbook Plan (PNLD) of 2014 were chosen. For the inferences of the data produced, a phenomenological interpretive analysis was used (TRIVINUS, 2012). It was found that the textbooks observed explain the chemical balance content without a rigorous concern with the criteria of contextualization, interdisciplinarity and experiments, although there is a recommendation in the Chemistry Book Guide, which is up to teachers who periodically choose the book. didactic adopt a didactic-pedagogical care regarding these choices.
