[R] OT: DOE - experiments for teaching

[Berton Gunter]

I've had fun and luck with the apparatus described in my little paper:

THROUGH A FUNNEL SLOWLY WITH BALL BEARING AND INSIGHT TO TEACH EXPERIMENTAL
DESIGN 
The American Statistician, 47, 4 p. 265-269 (1993)

We continue to use this in our industrial training.

I also would strongly second Spencer's remarks re the difficulty of helping
students see the big picture. For some reason, viewing experimentation as
part of an overall learning process/strategy does not seem to be part of
most scientist's or engineer's formal education. I suppose if you look at
typical science or engineering labs where the goal is to come to a
predetermined conclusion, it's not hard to see why. But we don't need to get
into that imbroglio here.
