SEQUÊNCIA DIDÁTICA SOBRE CINÉTICA QUÍMICA: O USO DE METODOLOGIAS ATIVAS COMO PROPOSTA PEDAGÓGICA PARA O ENSINO DE QUÍMICA

Abstract

In the educational context, teaching methodologies play an important role in improving school performance. Thus, the choice of this should allow the content studied in the classroom to be used to form a critical sense in students, making the environment conducive to debates and using it as a means of student-teacher interaction. Therefore, the objective of this research was to produce, apply and validate a didactic sequence (DS) based on the use of active methodologies as a pedagogical proposal for teaching Chemistry. This is an applied research with an exploratory character and a qualitative approach, using action-research procedures. The instruments used for data collection were: participant observation, application of questionnaires, field diary notes and production of participating students, with David Ausubel's Theory of Meaningful Learning being the research's theoretical foundation. The educational product, the result of the dissertation, entitled “Didactic Guide for teaching Chemical Kinetics: a proposal for a didactic sequence using active methodologies” aims to contribute to the teaching of Chemistry in Basic Education classes, specifically the content of Chemical Kinetics, seeking to provide autonomy, dynamism and motivation to students and collaborating as a pedagogical tool for teachers who teach Chemistry. The DS was structured in the Three Pedagogical Moments and applied to students in the 2nd year of high school at a school belonging to the State Education Network, in Pires do Rio, GO. From the interpretation of the results, we believe that this research is relevant for society by exploring new methodological conceptions that allow students to have more dynamic, attractive and interactive ways of building knowledge and assimilating Chemical Kinetics content. Thus, SD corroborates the development of students' protagonism and autonomy as subjects involved in the teaching-learning process.
