How do you teach kids coding when you can't code yourself? The short answer surprises most parents: the essential skill is not the language. It is the ability to hold back the answer.
A child stuck in Scratch rarely needs an adult who can see the bug. They need one who asks the same question until the child sees it — and there, parents who can't code have an advantage nobody tells them about.
What programming actually is
Programming is writing a sequence of instructions that a machine follows literally. That last word is the whole thing. A recipe says "add the flour" and leaves you to decide how much. A computer leaves nothing to you.
So the most common moment in programming is not something working. It is something doing what you said instead of what you meant. The Scratch cat walks left when the child wanted right. The program is not confused. It did as it was told.
A computer does not do what you mean. It does what you said — and the gap between those two is nearly everything a child has to learn.
Here is the reversal that concerns you: an adult who can code spots the bug in two seconds and fixes it. It feels helpful. But then the adult did the searching — and the searching was the lesson. Someone who can't code can only ask.
Why it matters
Debugging is the part of programming that outlives everything else. The blocks your child uses today may not exist in ten years. The habit of hunting for where a plan cracks moves straight into maths, into writing, into a broken bike gear. The curriculum asks for exactly this: mathematics has competence aims about programming algorithms with variables, conditions and loops.
Try it at home: four questions that find the bug
Ages 7–13. Fifteen minutes. You need Scratch or ScratchJr (free), a project your child made, and paper.
- Let your child build something that does one thing: the cat walks to the ball.
- Run it. Wait until it does something other than intended.
- Ask: "What does it actually say here?" Read the blocks out loud, one at a time.
- Ask: "What did you think would happen?" Sketch the route on paper as they talk.
- Ask: "Where do the two stories stop matching?" That is the bug — and the child found it.
- Ask: "What do you want to change — one thing?" Change only that, and run again.
Stick to the four questions. Point at the right block and the session is over: the child got an answer instead of a method.
Questions to wonder about
- Why is explaining how to tie a shoelace so much harder than tying one?
- Is there an instruction so precise nobody could misread it?
- If a computer only does what it is told — who decided what it should do, and how would you find out?
Every child is made of good atoms — and some of them shine brightest the moment a child finds their own mistake.
