As atividades experimentais nos livros didáticos de química

Abstract

The textbook is a didactic artifact that is composed of the organization of the curriculum of the areas of knowledge, hence its importance as a support for greater accessibility for students and teachers and as a guiding element for the teacher's pedagogical practice. And this support, when suggesting the use of experiments, can play an important role in bringing Chemistry content closer to the students' reality, when they are carried out in the classroom with well-defined objectives, careful planning, prior knowledge of the teacher's resources and understanding of the concept to be achieved, and students' ability to handle and use chemical experiments. Observing these aspects, this research work was carried out with the objective of analyzing how Chemistry textbooks approved in the National Textbook Program 2021 present the content of Chemical Kinetics. The work deals with documentary research where we analyzed how the experimental activities are presented in the Chemistry books for the 2nd year of High School proposed by PNLD 2021, with regard to the content of Chemical Kinetics. The results reveal that all the books analyzed have experimental activities and that they have a demonstrative, illustrative/descriptive and investigative approach. The experimental activities analyzed do not require a laboratory or specialized material, since the experimental proposals allow for their execution in an accessible manner, which can significantly contribute to making experimental activities viable in a school environment, enabling the proposition of real problems, promoting contextualization and questioning, which in turn instigates investigation
