Characterization of the chemical discourse of a group of teachers in initial training through a didactic sequence for the teaching of thermal equilibrium

Abstract

This article is configured as a research report that focuses on the development of the chemical discourse of a group of teachers in initial training, which provides elements in the research in Chemistry didactics. To do this, a series of activities were designed on the conceptual network of thermal equilibrium that made it possible to analyze the concepts, ways of meaning and representations used by teachers through three significant relationships categorized according to the structure / composition and energy dimensions in the molar and molecular levels proposed by Jensen. The results and the analysis show that the group of teachers identifies and recognizes the relationships between the conceptual networks approached in correspondence with the levels and dimensions evaluated, which made it possible to strengthen the chemical discourse, fundamental for the appropriation of a scientific language and therefore of a chemical scientific knowledge in the initial training of teachers.
