摘要：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.
