Focus on Project Based Learning

I think I understand Project Based Learning on a basic level, but I am struggling with its implementation in my classroom.  I've spent several days contemplating ideas for topics, rubrics, products...but I just can't seem to make anything fit.  Today I came to the realization that it's not the subject area (Reading and Writing) that are causing me problems.  It's how does all of this fit in the grand scheme of what the state of Texas is now calling STAAR?

Because so much in Texas is tied to the high stakes test - accountability ratings that drive funding, jobs, programs - I'm not sure how to make sure they get the skills necessary to do well on the STAAR through more personalized, student-directed learning.  I believe that if we teach students to read critically and write well, there should be no problem with a minimum standards test.  So...how do I make this work through Project Based Learning?

Granted - I have not attended workshops or training on PBL, but am anxiously looking forward to attending a WOW (Working on the Work) workshop this summer.  Maybe this will put it all in perspective.  Any thoughts on other ideas or things to read are welcomed.  (I'm about to start Schlechty's Working on the Work - that's on my spring break list.)
