5 p, 260.8 KB Un avance decisivo en el conocimiento de los iones : la teoría de Arrhenius de la disociación electrolítica / Galache López, Isabel (Universidad de Málaga. Departamento de Química Inorgánica, Cristalografía y Mineralogía) ; Camacho Domínguez, E. (Universidad de Málaga. Departamento de Química Inorgánica, Cristalografía y Mineralogía)
The aim of this article is to have a better understanding of the development and evolution of the concep of ion, up to the present moment, since it was introduced by Faraday. We have focused our attention on Svante August Arrhenius, a very relevant scientist in the history of Chemistry, who made the most important progress in the investigation of the nature of ions, being the central figure in this field.

14 p, 455.6 KB Los suelos en la enseñanza de la teoría ácido-base de Lewis : una estrategia didáctica de aprendizaje por investigación / Salcedo Torres, L. E. (Universidad Pedagógica Nacional (Bogotà, Colòmbia). Departamento de Química) ; García García, José Joaquín (Universidad de Antioquia. Departamento de Enseñanza de las Ciencias y las Artes)
This article describes and analyses the results obtained in a didactical experimental strategy, structured in the Teaching and Learning model which is based on research. The students are involved in situations, where problems related with the soil are used in order to help the significative construction of the acid and base's concepts related to the Lewis' Theory in order to increase the students mental ability for analysing and synthesizing and also to develop their attitudes towards science.
