Determinação de álcool na gasolina comum como estratégia para o ensino de soluções: a utilização de atividade experimental na Educação de Jovens e Adultos

Abstract

This study, included in the theoretical framework in Chemistry, aimed to promote learning in the Teaching of Chemistry in the Education of Young and Adults (EJA) of the first year of high school, through the use of a Teaching Strategy (EE) for experimentation. In order to do so, a product was created, more precisely a teaching strategy (EE), whose title "Determination of the alcohol content of gasoline" sought to promote the relationship between the student's previous knowledge and the construction of scientific knowledge in relation to the concepts of chemistry present in social everyday life such as mixture, density, volume. The experimental activity was carried out with the 1st year of the Secondary Education Course of Young Adults Education (EJA), in the Federal Institute of Goiás, Jataí Câmpus. At the time, the class was divided into six work groups and the activity was distributed in six classes of 45 minutes each. The methodology adopted followed the parameters proposed by Delizoicov, Angotti and Pernambuco (2011), that is the Pedagogical Moments, consisting of Initial Problematization, Knowledge Organization and Knowledge Application. The results obtained with the experimental activity not only attested to the participation and interest of the group in the development of the activity but also pointed out the relevance of the use of the experimental activities in the teaching of Chemistry, since such activities encourage dialogue between popular knowledge and scientific knowledge, considering that chemical events are constitutive parts of society. In addition, the educational legislation itself requires that education must be promoted in the sense of educating for life and for citizen construction, leading the subject to make productive decisions in a personal and social context.
