In the theoretical framework of Vygotskij's Theory this report discusses the mediating function of particular tools available in a microworld. Following the analysis carried out by one of the authors, in the case of Cabri a new microworld has been set up and a teaching experiment carried out. Some results are reported and the theoretical notion of semiotic mediation discussed.
