Project-based learning (PBL) is an approach to teaching and learning that engages students in ways that traditional classrooms often don’t. One group that provides resources to help teachers create and implement PBL is the Buck Institute for Education. They have created a framework called “Gold-Standard” PBL, and many of the resources they offer are free on their website.
Also, Thom Markham is a PBL advocate, leadership coach, and prolific tweeter. His organization is PBL Global.
