      Simple, and yet...
      By Uncle Bob on 04/17/2012 - 11:03
    • It is surprising how much spatial thinking goes into a simple task when learners are encouraged to use as few guesses as possible. Is a 3x2 arrangement tall or wide? What is the best place to make a first guess ... a next guess? When do I have enough information to be certain?
