Do's and Don'ts for IT training classes?

Look at Apple online help, and write your materials accordingly. Do it step-by-step, and let everyone do hands on lessons. Let them ask questions. Do a follow-up survey from the first class to see if you should change anything. If you uses Sharepoint, create a training site they can reference back to.

Do more practical than talking. People tend not to understand what you are talking about till they see it & try it on their own.
