IDesign - design thinking
Idesign is an interesting website that provides a well constructed overview of "design thinking". The approach introduces 7 ways of design thinking, and covers everything from the underpinning theories, to practical teaching tools and techniques, to forms of assessment.
Most of the information on this website was originally developed during the Design Based Education K-12 Program at the University of the Arts in Philadelphia, PA, USA. Initiated in 1989 by Dr. Burnette, the program began with a university course, Design With Kids, that placed design students in classrooms to help teachers conduct design projects related to their teaching goals.
