ab: Summary: This study explores interactions with diagrams that are involved
in geometrical reasoning; more specifically, how students publicly make
and justify conjectures through multimodal representations of diagrams.
We describe how students interact with diagrams using both gestural and
verbal modalities, and examine how such multimodal interactions with
diagrams reveal their reasoning. We argue that when limited information
is given in a diagram, students make use of gestural and verbal
expressions to compensate for those limitations as they engage in
making and proving conjectures. The constraints of a diagram, gestures
and linguistic systems are semiotic resources that students may use to
engage in geometrical reasoning.
