In this article, the authors present relevant relationships between history, epistemology and didactics of natural sciences. Each of these categories is analyzed based on the real practice of some educational systems and some proposals are outlined in order to improve them. Each one of the scientific models should be the focus of classroom work, taking into account the characterization of the foundations which have led the scientific community to state and accept them. The main objective is to start a reflection based on didactic research in which the established relationships overcome different isolated points of view.
