Interesting comment from my class today raises some questions about the peer
feedback process.  As we went over the scoring for the first peer
assessment,  we were talking about how to write a constructive/useful
comment answering the question about the "single most valuable thing a team
member contributes" in the case when a team member does not contribute.  One
student pointed out that if she has a team member (Bob) who never
contributes (or rarely shows up) she would just have to "make something up"
in order to get a good score on the usefulness of her feedback. 

So my first question is, if  Bob is really slacking and not making a
contribution, do his teammates get marked down if they can't identify a
contribution Bob makes? 

This raises a second question.  If Bob (from above) is not really involved
or not attending, how do we justify using his quantitative assessment scores
to evaluate his teammates?  

Eager to hear from y'all.
