Keywords:

Chemical change, chemical reaction, chemical equation, model.

Abstract

In the French chemistry syllabus of higher secondary school, 20 years ago, a macroscopic model was introduced to foresee the evolution of chemical systems. This macroscopic model, the chemical reaction, is distinct from the chemical description of the system modifications, the chemical change. This paper presents an epistemological and didactic analysis of this syllabus and an overview of how students and teachers understand it.

keywords: Chemical change, chemical reaction, chemical equation, model.
