ABSTRACT
We present one component of a foundation for mobile, handheld device-supported collaborative learning (mCSCL), a design framework. Our design framework proposes that mediation can occur in two complementary layers, social (e.g. rules and roles) and technological. Further we suggest that for mCSCL, the technological layer has two components, representational mediation and networked mediation. A particular design challenge is achieving an effective allocation of supporting structure to each layer as well as simple, transparent flow between them.
