If your training sessions will include only experienced teachers who are new just to the computer classroom, then you can concentrate much less on explaining teaching techniques and much more on the unique features of teaching in a computer classroom. If you are training teachers new both to teaching and to computer classrooms, then you need to emphasize different elements in your training program. Brand-new teachers might not know, for instance, how to set up group activities. So in addition to explaining how the classroom dynamic changes groups, you'll need to review the basics of setting up groups. Our general rule of thumb is that training brand-new teachers takes longer and changes the order of our discussions to emphasize more basic elements of teaching first with more detailed explanations of computer supports later in the training sessions.
