Ah, I used to think the same thing, but this is not true. Here's how
to workaround it.
1. Set the quiz up ahead of time as you normally but don't enable
feedback on the quiz.
2. But ALSO hide the item in the grade book before and during the
quiz, so they can't see the score they got (with or without feedback).
3. After the team has taken the group RAT, you can go back and turn on
both the individual quiz feedback AND the grade book display of their
score.
Without both being turned off, you're right, it's possible for a team
member to deduce what the correct answer is (through quiz feedback) or
whether they did well enough overall for other team members to trust
their answer (through the grade score display).
Sure, this is a little bit of work for the instructor to have to
remember to go back and turn these on, but hey, at least the IRAT test
score is graded and recorded, which eliminates some of the
administrivia.
Best,
John
