Hi all,

I’m looking for some peer evaluation guidance.

I use peer evaluations to adjust students’ averages across the team
quizzes. I use the Fink Method to conduct this adjustment. This is where
the ratio of the student’s average peer evaluation score and the team’s
average peer evaluation score is multiplied against their average across
the team quizzes.

This works great, except in cases where there is one team member that gets
a peer evaluation score that’s much, much lower than their teammates. This
pulls down the team average and results in the person with the low
evaluation taking a big hit on their team quiz score while the other team
members get a big boost (sometimes adjusting their team quiz scores well
above 100%).

To deal with this I’ve thought of treating the team member with the really
low evaluation as an outlier, removing their score from the adjustment
calculations, and just applying a set deduction to their team quiz average.
The challenges with this approach are:

   - What criteria do I use to identify outliers? How much lower do their
   peer evaluation scores have to be from those of their teammates?
   - How much of a set deduction should I apply?

Has anyone else dealt with this issue? Any suggestions or thoughts? I’m all
ears!

Thanks,
John
