"One of the most useful things to do as you think about teaching in a computer classroom is to spend some time literally playing with the resources. Don’t worry! You can’t break a computer just by typing and inputting commands. See how easy it is for you to use the resources. Have an experienced person walk you through some of them. Fiddle with the DAILY functions, email, newsgroups, etc. Try out some of your ideas before using them in the classroom. This will help you become more comfortable with the system and help you anticipate problems and successes your students might have."
