This chapter critiques design and design practices from historic, social, cultural and sustainable perspectives as a basis for opening up a broader perspective on the ways design and designing are seen within mainstream Design and Technology education in schools. The chapter is divided into four broad sections. The first section explores the ways that design practioners, theorists and historians critique past and present practices of design from within the profession. This is followed by an outlining of approaches that some designers have taken to using design itself as a way of critiquing society and culture. The focus then turns to Design and Technology education and highlights concerns that have been identified both at school and higher education level. Finally, consideration is given to examples that illustrate positive approaches to bringing broader and more critical approaches to Design and Technology in classrooms, including ways that are developed in detail in further chapters in this book.
