THE MATHEMATICS IN OUR HANDS - CHRISTINA M KRAU...

In her empirical study  Christina Krause investigates how gestures can contribute to epistemic
processes in social interactions. She expands the traditional speech-based approach to
analyzing social processes of constructing mathematical knowledge by employing a multimodal
perspective. Adopting a semiotic approach  she takes into account two functions of gestures as
signs used by the participants of the social interaction: the representational function
concerns the ways in which gestures take part in referring to a mathematical object in
processes of knowledge construction and the epistemic function relates to the ways in which
they can contribute to the performance of collective epistemic actions. The results of this
study reveal that gestures influence the epistemic process significantly more than previously
thought and indicate factors underlying this influence.
