Abstract
This theoretical report addresses the theme of the PME Conference (“In search for theories in Mathematics Education”). The history of two interlaced research programs (Mathematical Discussion and Mathematical Machines) headed by the author is outlined, together with the merging of both, combined with studies on information and communication technologies. They are the roots of the theoretical framework of semiotic mediation after a Vygotskian approach (Bartolini Bussi & Mariotti, 2008). May this framework answer the present needs of focusing cultural historical issues and the teacher'.
