Uma proposta de contextualização no ensino de Química: o uso das plantas medicinais aplicadas ao ensino de funções orgânicas

Abstract

The teaching of chemistry, makes it possible to relate information from the social context to the formation of the citizen in a society. In this way, new methodologies are inserted to make it motivating and interesting. Thus, this work aims to elaborate a didactic proposal for the teaching of organic chemistry, which involves the contextualization of the content of organic functions in the classroom, based on students' popular knowledge about the use of medicinal plants in our culture. For that, the application of an investigative questionnaire and a contextualized class was developed to analyze the students' previous knowledge about the subject and to bring them closer to the content of the organic compounds. Subsequently, a proposal was made through primers in chemistry teaching, so that the students identified the functional classes present in the chemical structures of the active principles of medicinal plants. Subsequently, it was suggested the elaboration of a team work entitled "The Chemistry of Teas" and the application of one of evaluative activity. Thus, the use of this methodology allows the student to identify the organic functions present in the chemical structures of the plants and shows that the use of the same provides a significant learning that awakens students curiosity and interest in the subject, the interdisciplinarity of content with the disciplines of the sciences and for the formation of the critical citizen
