Question

A teacher sets up a machine that beeps at random intervals; research has demonstrated that, if students check "yes" or "no" in answer to whether they were paying attention when the beeper beeps,

Answer 1

The children will actually improve their attention to the task. The beeping sound will keep the children aware of their surroundings and will make sure that they are staying on-task, even when the beeping is set to a completely random timeframe.
