Public Art in Chicago History (PACH) was a summer professional and curriculum development program for Chicago public school teachers, focusing on investigating ways to integrate public art into middle and high school classrooms. Participating teachers attended five workshops during which they viewed significant works of public art in downtown Chicago, read books and articles by historians and art historians about those works of art, and discussed key concepts of visual literacy to help them use the works of art and others in their classroom instruction.
