Hi John,
I have a few of questions for your consideration.

  1.  Could you simply use the iRAT scores as the adjustment for quizzes?  If they are scoring high or low on the iRAT, would that be enough to provide the accountability you seek?  My understanding was that peer evaluation scores would be used to adjust complex applications or be treated as a separate grading category.
  2.  Could you set upper and lower bands on how they can rate anyone who showed up for the RAT?  (For those absent, I let my students choose what % of the team score to give the missing member without affecting the team score.  I encourage them to set their own rules on how this will be handled, such as requiring notification if they won’t be there or number of times they get a pass.)
  3.  Could you establish a rule that no one will receive more than 100% or 105% of what the tRAT was worth?
Hope this helps!

Subject: Peer evaluation guidance

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
