This is the title of an article by Christina Farr about the project-based learning program NuVu Studio where students enrolled in the program learn by solving real world problems.  For example, a project for one group of students was to make a  mock up of an affordable prosthetic hand.  After conducting interviews with amputees and their families, physicians, and engineers, the students designed a prosthetic device and produced it on a 3D printer.  This is an interesting, thought provoking article.
