El desafío de la calidad : un mensaje pedagógico básico para el trabajo experimental en química analítica

Abstract

The aim of this work is to improve the experimental teaching in Analytical Chemistry Labs. It is being developed from the investigation-action model. Analytical Chemistry is an intelectual attitude. We think about it as a scientific subject. The basic pedagogic aim of teaching theory and programming the analysis applying the analytical process is to incorporate it into mental structures. A conceptual approach to complete analytical process in experimental teaching is shown. The student is guided to obtain qualified analytical information. Different practical works of increasing complexity are gathered and evaluated. The results of these experiencies are analysed. The pedagogic challenge is to revise thoroughly the understanding of everyday teaching in Analytical Chemistry. Specially experimental work, since new technologies undergo quick changes and they are not always efficiently applied.
