Aula temática como proposição metodológica no ensino de química usando os flavedos da citrus sinensis para obter óleo essencial

Abstract

The article discusses the countless difficulties that students face in understanding chemical concepts, as the discipline is seen as difficult and abstract without dialogue with practice. Thus, the problem observed in the school context revolves around the assimilation of literary-conservative practices with the absence of practical activities in daily classes. When questioning the contributions of providing methodological tools, through thematic workshops, in practical activities for teaching chemistry in public schools, one can notice the help due to lack of resources. Thus, the objective of the study is to present a teaching methodology through a thematic workshop combined with experimental activities carrie out by the apprentices themselves. The methodology used was based on the qualitative paradigm with the descriptive / explanatory method that was carried out as an experiment in the thematic workshop the extraction of the Essential Oil from the Citrus Sinensis Flavedo (EOCSF) as a way of reuse, with adequacy the use of alternative materials. The results show that students had a greater understanding of chemical concepts, through new discoveries about the theme and that they built a relationship with their daily lives making it relevant. They were also shown to be motivated and involved during the thematic workshop, giving meaning to their learning in the construction of their own knowledge of the chemical concepts studied in high school, as methods of separating mixtures involved in the process.
