I will say that the idea of "learning by doing" applies elsewhere as well. I had to learn our system in a hurry doing just that when the administrator walked in one day and said he would be gone for three months because he was having a quadruple by-pass heart surgery the following week. Nothing like learning with trial by fire.

I also recall a Chinese Proverb:
Tell me, I forget
Show me, I remember
Involve me, I understand.

I think some of that might apply here :-)
