Through two experiments with pre-schoolers, Bonawitz has found that teaching can be a “double-edge sword”. When teachers provided specific instructions about a new toy, children learned how to play with it more efficiently. But the lessons also curtailed their exploratory streak. They were less likely to play with the toy in new ways. Ultimately, they failed to find all of its secrets.
