Love the third link down on the left side. Click on it to see the students with their "projects."
Do they get credit for this? What's the grading scale - is it based strictly on points bagged? Or do they take an average of the total points bagged (is 'bagged' even the right term to use here?) and base individual grades on percentage of the total? How many points do you have to get if you want an A?
Please post your comments on how you'd grade these kids.
