The notion of “theoretical model” in chemistry education: representation and role of the periodic system

Abstract

 This paper approaches from a semanticist point of view one of the structuring themes of chemistry: the periodic table. The anchoring to the structuring themes of chemistry through a current approach to the philosophy of science could introduce, in the teaching of chemistry and the training of chemistry teachers, current, renewed and powerful metatheoretical reflections to understand the nature of chemistry (as an activity) and its theories.
