To demonstrate that it is the structure of the task, not individual performance, that controls the range of normal variance of task outputs.
GAME 1 -- (materials needed: several sets of OV's showing cards, removable covers.)
1. Avoid bad card dealt face down: overhead reproductions of sets of cards with covers for overheads.
variation a. Use same set to permit memorization. Evaluation unfair to first person.Discuss how structure of task affects estimations of ability
variation b. Change set to frustrate learning: Unfair to all
2. Keep statistics to determine + and - 2 sigma as limits.
Note: that odds are theoretically computable
GAME 2 --(needed: a. set of thumbtacks; b. set of different colored thumbtacks.)
1. Throw tacks.
A. Throw a handful of same colored tacks to get points down.2. Compute statistics. Note that odds are not theoretically computable.
B. Mixed two colors of tacks, to throw one color points up.)
