After that jargon filled, cliche ridden, Bloom's taxonomy flavored introduction, you must see where I'm going with this.

Note all words that make a student cringe are identified in quotations.
What if my highschool English students were given the opportunity to pursue a passion of theirs as a "unit" of study? What if the "assignment" were simply to pursue their passion? Take a topic and research it, compile information about it, reflect on it, create on it, share it, act on it. What would the "criteria" be. How would it be "assessed"?
Would this cause them, as I am now, to write a blog post on a Saturday night and peruse their RSS feed for hours while simultaneously taking part in a free online course instead of watching the movie they'd rented earlier?
Okay...now I'm getting silly, but you get my drift (and for the record, I don't do this every Saturday night).
