Schauen Sie sich das kostenlose Video Guided Access an

Guided Access is a fantastic feature in iOS 6. It allows teachers to lock the iPad into a certain app, in order to help students stay where they want them. This is especially useful for younger children, who may have difficulty following directions, or any student who needs assistance to stay in the right area.
This video will teach you how to get in and out of Guided Access mode, as well as provide an overview of the functions.
