studies have found that when children are simply taught, they don’t explore and test multiple hypotheses
[In one study of preschoolers,] an experimenter held a toy that had four tubes. Each tube did something different — for instance, one lit up and one made a squeaking sound.
In one case, the experimenter accidentally made the toy squeak by bumping into it and then left the room. The children experimented with the toy and figured out the three other features.
But when the experimenter made the toy squeak on purpose and then handed it to a child, he or she simply repeated what the experimenter did and never explored the toy’s other features.
