Gesture enhancement of a virtual tutor via investigating human tutor discursive strategies: Forms and functions for proportions

  • Author(s): Flood, VJ
  • Schneider, A
  • Abrahamson, D
  • et al.

We examine expert human mathematics-tutor gestures in the context of an interactive design for proportionality in order to design a virtual pedagogical agent. Early results implicate distinct gesture morphologies serving consistent contextual functionalities in guiding learners towards quantitative descriptions of proportional relations.
