Now imagine handing out iPads in a classroom riddled with students like Chet, who have these strong cravings owing to excessive nightly gaming. Ed-tech advocates would say that a strong teacher presence in the classroom could prevent misuse of the devices, keeping kids on track and productive. But is this a reasonable expectation for a teacher (or anyone, for that matter)? This would be like handing out full glasses of wine at an AA meeting and asking the leader to make sure the meeting participants were only using them to make music on the rims.
