Modelos, analogías y metáforas en la enseñanza de la química

Resumen

Models, analogies and metaphors are strategies for constructing the knowledge because they construct, compare and evoke images. Models, analogies and metaphors are frequently used in chemistry teaching although of a non conscious or planned way. In this article, the relationships between models, analogies and metaphors are presented. Some conclusions about teaching with them are also showed. This work is based on the plenary conference presented for the author in the V International Meeting of Chemistry Teaching at College and Precollege Levels Santiago de Chile, November 13-16, 2007.
