Teaching children
Don’t limit a child to your own learning, for he was born in another time - Rabbinical saying.
Isn’t that appropriate in the present time? If we teach our children only what we know, they will fall so far behind, they will never even enter the 21st century.
That is the excitement of the 21st century for me - that we can teach our children (and grand children) things we do not know. All we need to know is how to teach them to be responsible web users, and let them loose.
