I think the beamer is just a projector. The setup is called a smartboard, essentially a touch canvas where the picture is displayed via ceiling mounted projector and connected to a desktop host. In other words, it's a giant touch screen monitor.
He should be able to change the input from the host pc to his tablet on the projector.
yeah pretty much this

just that the school didnt buy and desktop host and asks the teacher to bring wahtever notebook/tablet he has.
