Reading rhetorical analyses, seeing lots of potential, but worrying that many students won't revise. Also worrying generally about the "blow-off" factor--ignore one assignment, only three need to go into the portfolio, etc.
That got me thinking: maybe I should have each "pencil draft" be worth 50 points (which would add up to 200 points total) and then have the portfolio be worth 500 points--the revised papers plus letter. That would encourage stronger drafts (perhaps), but not destroy someone's grade if he / she did poorly on a draft. It would also result in lower grades overall (likely), but would also perhaps discourage me (and others) from giving really honest feedback (would I give out 30/50 if it wasn't erasable?).
Quick thought I didn't want to lose--back to grading.
