The Complexity of Representations in the Chemistry Teaching: An Experience for Atomic Model

Abstract

This work presents a portrait of research in chemistry education addressing the prob-lematic 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 diffi-culties 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. Key words: modeling; representation of chemical knowledge; teaching of chemistry; visuali-zations.
