A contextualização e a interdisplinaridade no ensino de Química: uma analise de livros didáticos ACIDO-BASE e das propostas pedagógicas realizadas pelos docentes diante da temática

摘要

Nowadays, chemistry contents taught in high school continue to be presented ina fragmented and decontextualized manner by the teachers and the textbooks.Even though it is known that contextualization and interdisciplinary exchangeplay an important role in the process of Chemistry teaching/learning. Therefore,the present study aims at enlightening the importance of these methodologicalfoundations in the learning of chemistry. The data acquisition about the subject Contextualization and Interdisciplinary Exchange involved in ChemistryTeaching was developed through bibliographical researches on chemistrytextbooks, which focused on the analysis of the topics acid and base , since itis a theme studied throughout all three years of high school. The present studyalso developed questionnaires which were applied to analyze to what extentchemistry teachers are working in a contextualized and interdisciplinary mannerthroughout the process of Chemistry teaching/learning. The results obtained inthe researches show that a contextualized and interdisciplinary teachingcontributes to a more meaningful acquisition of chemistry knowledge, in adynamic and interactive way, but there are still many roadblocks towards theachievement of this kind of Chemistry teaching/learning process
