Avaliação sobre modelos atômicos no ensino de química sob a perspectiva semiótica de Pierce e Saussure.

Abstract

In recent decades there has been a deepening of studies involving problems related to teaching and learning in chemistry, seeking solutions that bring the classroom closer to the scientific environment and the necessary reflections aimed at the development of the individual, regarding the formation of critical citizens and authors of science. transformation of your reality. This work seeks to investigate the possible causes of the chemical-conceptual discrepancy in the school environment, starting from the semiotic analysis of Peirce and Saussure. For this, the work is based on the analysis of three publications on: the conception of atomic models by students through a project carried out by graduates of the Federal University of Sergipe (UFS); the representations in the Chemistry LD under the title ''Citizen Chemistry'' identified in the PNLD 2015 by Editora AJS, 2nd edition 2013, by the coordinating authors Wildson Luis Pereira dos Santos and Gerson de Sousa and the third publication consists of the analysis of the semiotic function involved in representations of the same work, focused on atomic models. Finally, the data were compared in the light of a literary review, leading to suggestions that improve the formulation and use of Chemistry textbooks in the school environment, bringing about real progress in the teaching and learning process in Chemistry.
