Instruments of semiotic mediation in algebra, an example
Abstract
The paper presents a class discussion which was set up within a long term experiment concerning the use of a software, L'Algebrista, to introduce pupils to theoretical thinking and symbolic manipulation. From the analysis of the discussion we will illustrate some aspects of how a teacher can use an instrument of semiotic mediation in order to guide the genesis and evolution of new concepts.
