ABSTRACT
The concept of socially shared cognition plays an important role in our efforts to create and sustain model systems of educational activity. In this chapter, our discussion of socially shared cognition focuses on our ongoing attempts to design, implement, and sustain educational activities in community insti tutions during the after-school hours. We use the notion of socially shared cognition to discuss two aspects of our work: (a) the organization of learning within educational play worlds called Fifth Dimensions and (b) the organiza tion of collaboration among a team of scholars conducting research on the Fifth Dimension.
