Abstract
In this paper we review major theoretical perspectives on differences between students in their thinking and classroom talk, and conclude that Bakhtin's concept of voice provides a powerful way of theorising difference that draws attention to the multivoca1ity (inherent diversity) of individual ideas and utterances. It is the orchestration of the diversity of voices that enables new insights to emerge both collectively and individually. We apply analytical tools (derived from Bakhtin) to an episode of collective argumentation focussed on the concept of infinity, and we identify key elements of everyday classroom practice that enable challenging and productive talk to occur
