Technologies can range from the simplest of shelters to keep us warm and dry, to the most complex bioengineering interventions. In this technologically mediated world we now inhabit, there is a growing need for human beings, and particularly young people, to be more critically involved in the discourse surrounding technology. In order to achieve a truly democratic world, any tensions or confusions between human beings, their environment, and their technologies must be resolved. Only then will people become empowered to improve their world in a creative, sensitive, informed and above all, sustainable fashion. This collection offers a solid basis for defining this new technological literacy by bringing together theoretical work that ranges from philosophy, design, and pedagogy.
