THE TOPIC BIODIESEL IN HIGH SCHOOL CHEMISTRY TEXTBOOKS

Abstract

The approach of cross themes is an option to facilitate the teaching and learning process of Chemistry. This study aimed to verify how the issue of biodiesel is being treated in chemistry classes in high school and its presence in the textbooks adopted by the teachers. For this purpouse, high school Chemistry teachers of five schools of Campina Grande-PB answered a questionnaire with open questions to collect data. The textbooks used were of the authors Geraldo Camargo (1997), Usberco and Salvador (2006), Sardella (2004) and Feltre (2005), where this last one was the most widely accepted and the only that is part of the federal government's program of Chemistry textbooks for high school. Regarding the presence of the theme of biodiesel in the textbook adopted, some teachers were unsafe in their answer or did not know how to answer, which shows that some of them do not have an idea about the content of the book they use. Most teachers claimed lack of time to address theme and it was showed that many of them followed the book adopted strictly. Then if the book does not cover the content, the teacher also did not do it.
