BIE is new to me. This organization is dedicated solely to PBL. Check out the vast array of videos from What is PBL? to How to do PBL to sample projects.
The resurces here are so helpful. Go to the tools tab and check out the planning forms.
There is also a great article that explains the difference between projects and PBL. You'll get a sense of how direct instruction is incorporated in PBL.
