Uso da Experimentação como ferramenta para o ensinode química em turmas voltadas para o ensino de jovens e adultos

Abstract

The use of experimentation in teaching science for groups of young and adult education (EJA) is still very scarce. The short period of time for studying all the contents of basic education, as well as the lack of teacher enthusiasm, are some of the reasons for this. Given this context, this work seeks to propose a low cost experimental class, using materials of easy acquisition to start studies on the content of organic functions. Vitamin C was chosen as the generating theme and the proposal was structured in four pedagogical moments. The research was carried out at the Jose de Borba Vasconcelos High School in Integral Time, located in the city of Maracanaú - CE and had as target audience 12 students of the EJA B class. An initial observation of the group was made so that the level of the students was analyzed through an introductory class of the school teacher. In the second moment, the students were offered a survey questionnaire that contained questions about the subject of the experimental class (vitamin C) and about the perspective of these students for the use of experimentation in teaching. In a third moment, a lecture on vitamin C and its properties was given, where an experimental class was applied with the objective of comparing the vitamin C content in different fruits. This stage of the process had the intention of encouraging the students to raise hypotheses and to suggest explanations for the observed events. They also answered questions of satisfaction and all stated in their answers that the use of experimentation in the classroom is of paramount importance for the teaching of chemistry especially for EJA classes.
