Uso de plantas medicinais no ensino de funções orgânicas, na turma de 3º ano “B” do CETI Deputado Pinheiro Machado em Cocal-PI

Abstract

The discipline of chemistry is considered difficult and tiresome by many students, thus requiring a more attractive methodology. The LDB nº 9.394/96 brings the contextualization in High School with a way of valuing everyday knowledge. Students are often led to memorize the contents, and with that they are unable to relate them to everyday life. So in Brazil it is common to use medicinal plants for the treatment of some diseases. With this, contextualizing in the classroom with medicinal plants allows working on various topics on organic chemistry.The present work was carried out at CETI Deputado Pinheiro Machado high school, in the city of Cocal-PI, with students from the 3rd year class "B" in the afternoon. Questionnaires were applied in order to obtain the results of the work, as well as an expository class dialogued with the students regarding the content of organic functions, contextualizing with medicinal plants. Based on the results of the questionnaires before and after, it was seen that the methodology was satisfactory since they had more hits after the lecture. That said, the importance of using new methodologies in the teaching of Chemistry is evident, especially in the organic discipline
