As a teacher, you immediately have my respect. Passing on knowledge is the most important thing a person can do, apart from teaching critical, logical and rational thought process and how to do research yourself.

The old saying - give a man a fish, you feed him for a day, teach a man to fish, you feed him for a lifetime. Sure you can impart all the knowledge the world has to offer, but with out teaching people how to analyse the knowledge they have and research further, it is useless.
