Guided Access is a feature of iOS 6 that allows users to prevent app switching and/or disable parts of the screen. It does not affect the way the app works unless you specifically set it to do so.
There are many reasons teachers might want to enable this feature on iPads in their classrooms. It may be a simple matter of keeping the students on task. Teachers may want to prevent students taking online tests from having access to Google or other search engines. Teachers using iPads in small groups may find that the minute or two spent enabling Guided Access is time well-spent when the iPads are ready for the next group without need for further teacher intervention. Guided Access can also be helpful if you want to disable areas of the screen, whether it is because you want to prevent students attempting to make in-app purchases, pressing the pause button, saving to the camera roll, or for any other reason.
First, enable Guided Access on your iPad. Go to Settings > General > Accessibility > Guided Access. You will need to set a passcode so you can turn Guided Access on and off and control the settings for each Guided Access session.
To start a Guided Access session, open the app you want to use and triple-click the Home button. If there are any areas of the screen you want to disable, circle them. You can use the handles to adjust the area. You can also set the iPad to ignore all screen touches by turning off Touch and keep it from changing orientation by turning off Motion. When you have set everything the way you want it, click Start.
To end a Guided Access session, triple-click the Home button and enter the Guided Access passcode.
The video below will give you a quick overview of what Guided Access looks like and how it works.
