Chemistry didactics in basic primary: theoretical and methodological reflections structuring for the teaching of the gas concept

Abstract

This article is configured as a research report, which focuses on the identification and selection of theoretical elements, typical of the chemistry didactics, which were incorporated into a designed and validated didactic sequence for the teaching of the chemical concept of gas. Aiming at the compliance of the research objective, a bibliographic review was carried out based on theoretical and methodological considerations, where the objectives of The Lesson Study led to the possibility of using the Química Paso a Paso as a complementary intervention methodology, to take an approach to the teaching of chemistry itself. The discussion of the theoretical and methodological panorama provided in this article made it possible to demonstrate the coherence and relevance of the theoretical elements of Chemistry Didactics in the design of activities for fourth grade students of primary school, accompanied by a dialogue between teachers.
