When musician John Roderick's 9-year-old daughter asked him how to use a can opener, he saw it as a teaching moment. He refused to show her and vowed that they wouldn't eat until she had puzzled it out. It took her six hours, during which Roderick provided hints, cajoled, philosophized and occasionally teased her.
Roderick documented the event on Twitter, and was excoriated. The typical sentiment was disgusted disbelief: Why not just tell her?
But this reaction shows overconfidence in the answer to a difficult question, one that's especially relevant as parents assist with remote schooling: When kids ask for help, what's the right mix of support and challenge? If you "just tell them," aren't you undercutting motivation and the chance to build independence?
For over a century, some education theorists have warned that kids who are "just told" might learn superficially. Virtually all researchers agree that understanding involves interpretation; learners don't simply absorb what a parent says, they create their own meaning. For example, if a child hears "Piera saw the doctor yesterday," she goes beyond the literal words and understands that Piera probably felt ill.
Because understanding is active, some theorists advise that the child should act while learning — that is, solve a problem or complete a physical task. Dissecting a frog requires thinking, while listening to an anatomy lecture enables students to only parrot information on a test.
American teachers agree. In a 2013 survey, 82% endorsed the statement "Students learn best by finding solutions to problems on their own." Roderick seems to be in good company.
But research tells a more complicated story. Guidance is critical — if kids are given a problem to solve or a frog to dissect with few instructions, they learn much less than they would if they had been given only an explanation. With skillful hints, however, learning from problems and activities can be equivalent, perhaps even a bit better than, learning from a lecture.
But the most intriguing prediction — that solving problems makes learning deeper — isn't true. In a study on early science learning, researchers taught third- and fourth-graders the importance of changing just one variable at a time in a scientific experiment. Some received instruction, then conducted experiments while others just experimented with little guidance.
