Abstract
This paper theorises an extension to a framework that structures students? interaction with technology through a series of metaphors: technology as master; technology as servant; technology as partner; and technology as extension of self. These metaphors provide insight into potential relationships between students? intentions, technological engagement and actions. The framework is conceptualized from within a socio-cultural perspective of learning/teaching mathematics and extends the Vygotskian principle of Zone of Proximal Development (ZPD) by elevating computer and graphing calculator technologies beyond that of simple cultural tools to that of quasi-partner or mentor. A component of the framework is used to analyse two episodes of student/student/technology interaction while working on a specific mathematical task. The extension to the framework has the potential to promote more sophisticated uses of technology in mathematics classrooms.
