THE COMPLEXITY OF REPRESENTATIONS IN THE CHEMISTRY TEACHING: AN EXPERIENCE FOR ATOMIC MODEL

This work presents a portrait of research in chemistry education addressing the problematic of the representation on chemical knowledge, interpreting them in an experimental framework that relates not only the complexity in the choice of materials, as well as the difficulties and methods. It was concluded that there is a need for a coherent pre selection of teaching materials to be used, and also that education based on visual aids and models need to be extensive, covering not just isolated events.
