Una trattazione unitaria difenomeni “diversi”: il caso del modello esponenziale

This paper reports a teaching approach to physics, developed for high schools and pre-service teachers formation courses, focused on modelling physical phenomena described by similar mathematical equations in different fields of physics. We start by analysing the phenomena and finding the relevant physical variables. Relations between variables are singled out using on-line laboratory. Then, modelling is introduced through a deep analysis of the interactions between the system under scrutiny and the environment.
