they can now also read all the class blogs (as they used to) and pass judgment on whether the blogs posted by their fellow students are satisfactory. Thumbs up, thumbs down. If not, any student who wishes can revise. If you revise, you get the credit. End of story. Or, if you are too busy and want to skip it, no problem. It just means you'll have fewer ticks on the chart and will probably get the lower grade. No whining. It's clearcut and everyone knows the system from day one. (btw, every study of peer review among students shows that students perform at a higher level, and with more care, when they know they are being evaluated by their peers than when they know only the teacher and the TA will be grading).
