Michael Raiber is a professor of conducting in the School of Music here
at Oklahoma. Last fall he sent me some data on the difference
between team scores and the average member score on an early RAT (see
below).
Question: Is this similar to what the rest of you experience
with you give RATs?
Another interesting question is how the team score compares to the
best member of the group. Usually the difference is not that
large early in the term. But as the teams become more cohesive, the
teams go further in outscoring even the best individual scores.
Is this
what you are experiencing, or not?

Dee-
I gave a practice RAT in my conducting course today and got some
very
interesting results I thought you might be interested in knowing.
The
following are the percentage increases of the team scores over the
average
individual scores of each team:
1 - +20%
2 - +15%
3 - +25%
4 - +56%
5 - +50%
6 - +20%
7 - +40%
8 - +5%
Average gain in scores: 28.8%
There are obviously a number of reasons for this, but any time we find
an
instructional design that can show this level of gains in student
outcomes,
it is powerful.
Just thought you would like the data.
Mike
