3. Reason

This chapter focuses on the design and use of interactive media to scaffold their users’ understanding of sustainability. The chapter traces the influence of concepts developed in complex systems theory on the design of sustainability games and simulations, and asks about the implications of using computational assemblages to represent and act on socio-natural systems. The image of sustainability that emerges from these media and the synoptic interactions they provide is of a complex problem that could be solved, or at least managed, by applying scientific methods and reasoning.
