The Interplay among Gestures, Discourse, and Diagrams in Students' Geometrical Reasoning
Chen, Chia-Ling; Herbst, Patricio
Educational Studies in Mathematics, v83 n2 p285-307 Jun 2013
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.
