What makes project-based learning successful

There is a small town, about 12 miles east of Austin, Texas, where a high school devoted to teaching every subject to every student through project-based learning (PBL) opened five years ago. On its own, this would not have been a noteworthy event. The list of schools across America deepening the learning process through PBL has been growing for quite some time. But few schools have fine-tuned the process like Manor New Technology High School in Manor, Texas, where 98 percent of seniors graduate and 100 percent of the graduates are accepted to college. Fifty-six percent of them have been the first in their family to attend college. (Mariko Nobori at Edutopia)
