Built largely for entertaining purposes by Apple, Apple TV is used increasingly in the classroom by educators who primarily want to take advantage of the mirroring capabilities of the device. For those who are not familiar with the term “mirroring”, simply put, a key feature in Apple devices called “AirPlay” can literally mirror or project your device’s screen (iPod/iPad/iPhone), via an LCD projector that is connected to the Apple TV. All you need aside from an Apple TV is an iPad 2 or newer, an LCD projector, and then, the sky is the limit.
Providing visual access to iBooks for all students with just one iPad in the classroom is, by itself, a reason for a teacher to buy an Apple TV.
