A relação teoria e prática na aprendizagem da química no ensino médio

Abstract

Chemistry is seen by many students as a complex subject and difficult to be understood. In this context, several studies carried out problematize the practices carried out in the teaching of Chemistry, in which students are induced only to decorate reactions, formulas and properties. Considering the difficulty of students in understanding basic concepts of the subject, the absence of experimental activities that can relate theory and practice and the subject taught without being linked to everyday life and its reality, causes a lack of interest of students in the study of the discipline and compromises learning Of these. This work aimed to analyze experimental activities in Chemistry in order to understand its importance in the teaching and learning process. The research was developed in two classes of the 3rd year of High School, in a State College in the city of Fortaleza, having as subjects 49 students. Two questionnaires were applied, containing objective and subjective questions, through which the students were able to present their conceptions about the importance of experimental activities in chemistry teaching. The analysis of the data showed that the students consider important the use of experimental classes in Teaching Chemistry, revealing that experimentation in Chemistry contributes to the consolidation of student learning, since it means the theory of chemical concepts, becoming. Thus, in an important didactic tool. The results also show that the student's daily life and the experiences he has are important for the development of cognitive knowledge and more meaningful learning.
