This chapter addresses the problem of moving students from critical self-reflection to the critique of design and technology. How and why do students become skeptical or critical of the designed world or more specifically of practices and products created for unsustainable consumption or planned obsolescence? After reviewing the history of the crit in D&T classrooms and workshops, this chapter addresses how students transfer dispositions from the crit to social critique of design practices and products. Conceptually, Schön´s work, especially The Reflective Practitioner, provides key insights into this problem. This is a problem of transferring activity to activism, from school facilities to everyday life external to schools.
