Your Child's Brain on Code: Why Coding Helps Children Who'll Never Be Programmers

Most children who learn coding will never become programmers. They'll grow up to be doctors, traders, nurses, farmers, lawyers and footballers. So why should a parent care about coding at all?

Because of what it does to how a child thinks. Let's look at what the research really says, in plain words.

The big number, made simple

In 2024, researchers at the University of Padua in Italy gathered every good study they could find on coding and children's thinking. They found 19 studies, with 1,523 children aged 4 to 16, from 2006 to 2022. Then they pooled 11 of those studies to get one big answer.

The answer? Coding lessons improved children's problem-solving. The size of the effect was 0.89. That number means nothing to most of us, so let's turn it into something you can picture.

Picture two classes. One class has coding lessons. The other doesn't. Then every child sits the same problem-solving test.

By our sum, using the study's 0.89, the middle child in the coding class would do better than about 8 in 10 children in the other class. If coding made no difference, that would be 5 in 10.

Coding also helped with planning, a bit less strongly. The effect was 0.36. By our sum, that puts the middle coding child ahead of about 6 in 10 children who didn't code. Still a real gain.

There were smaller gains too, in self-control (stopping yourself from rushing) and in working memory (holding things in your head while you work). The researchers called these "lower" effects, but they were there.

Just 8 hours made a difference

You might think this needs years of lessons. Not always.

In 2020, Italian researchers ran a fair test with 179 first-graders, children of about six, in 10 classes across 5 schools. Some classes got 8 hours of free Code.org coding lessons: two lessons a week for four weeks. The other classes got normal science and maths lessons.

By our sum, that's about 2 hours a week. Less time than many children spend on a single Saturday film.

The coding children got better at planning and at stopping themselves from acting too fast. The researchers wrote:

"Gains in coding skills are transferred to children's executive functions." Arfé, Vardanega and Ronconi, Computers & Education, 2020

"Executive functions" is the scientists' name for the brain's manager: the part that plans, focuses and keeps you from rushing.

It's not really about computers

Here's the part that matters most for parents.

The skills coding builds aren't only computer skills. Planning, breaking a big problem into small steps, and checking your work are what a child needs for a hard maths question, a long essay, or a science practical.

What happens in a coding lesson is simple. A child gives the computer instructions, one step at a time. If one step is wrong, the program doesn't work. So the child has to find the mistake and fix it. Programmers call this "debugging".

In our view, this is where much of the value lies. Coding makes a child's mistakes visible straight away, and it rewards trying again. Very few school subjects do that so clearly. One small 2026 study of 62 children aged 5 and 6 found that coding and debugging skills went together with being able to switch between tasks. It's early evidence, but it points the same way.

What about maths and reading?

Here, the honest answer is "maybe".

In America, a 2024 study tested a coding course called "Coding as Another Language" with more than 680 children aged about 5 to 8. The course was 24 lessons, about 18 hours, using a free app called ScratchJr.

The course on its own didn't raise maths or reading scores. But the children whose coding skills grew the most also did better in maths and reading. That's a link, not proof that coding caused it. Still, it's a good sign.

A small Turkish study of 29 preschool children found that those who did coding activities scored higher in maths reasoning afterwards. It was a small study and not a fully fair test, but again, it points the same way.

Professor Marina Bers, whose lab at Boston College hosts that study, calls coding "the new literacy". Her point: in today's world, being able to read and write code is like being able to read and write words.

What teachers and parents say

In 2021, OKdo, a UK technology company, surveyed nearly 7,000 UK parents and teachers. Among the teachers:

• 96% had seen coding lessons help children with other skills.
• 82% said it improved problem-solving.
• 68% said it helped with maths.
• 60% said it improved creative thinking.
• 35% said it helped with organisation and time management.
• 34% said it improved teamwork.
• 19% said it improved children's overall school results.

Look at the first and last numbers closely. By our sum, teachers were more than 4 times as likely to see better problem-solving (82%) as better overall results (19%).

That fits the research. Coding sharpens how a child thinks. It isn't a magic button for higher marks in every subject. Remember too that these are opinions from a company survey, not test results.

The honest catch

Coding is good for the mind. It isn't magic.

In 2021, researchers at Koç University in Turkey ran a fair test with 174 children aged about 9 and 10. For 10 weeks, children did either coding, maths or reading lessons.

Only the coding children got better at "computational thinking", which means thinking in clear steps like a programmer. But a general reasoning test went up in all three groups, probably just from practice. And none of the groups got better at picturing shapes in their heads.

The researchers said learning to code can be "selectively beneficial". In plain words, it helps some thinking skills, not all of them. So be careful of anyone who promises coding will raise your child's IQ.

Where Nigeria stands

Nigeria has started to take this seriously.

In September 2025, the national curriculum body, NERDC, announced a new school curriculum from the 2025/26 session. "Digital Technologies" is now a core subject in junior secondary and one of five compulsory subjects in senior secondary. Primary 4 to 6 pupils get "Basic Digital Literacy".

But there's a problem. Earlier that year, the head of UBEC, Aisha Garba, said:

"less than 50 per cent of public primary schools in Nigeria have digital technology" Aisha Garba, UBEC, May 2025

So by her own count, more than half of public primary schools lack the tools to teach it.

Here's why it matters. A World Bank and IFC study found that by 2030, 35 to 45% of all jobs in Nigeria will need some digital skills. By our sum, that's roughly 4 in every 10 jobs. The same study found only about 27% of households could afford basic digital training. That's about 1 in 4.

And look at the government's own big training plan, 3MTT. Its target is 3 million trained Nigerians. By January 2026, about 135,000 had been trained. By our sum, that's about 4.5%, or 1 in every 22 of the target.

Now think about our children. By our sum, using World Bank 2025 figures, about 96 million Nigerians are under 15. That's more than 4 in every 10 people. That's a huge number of future workers.

The good news: you can start on a phone

You don't need a computer lab to start.

Nigeria's 2021 household survey (MICS) found that about 9 in 10 homes own a mobile phone, but only 9.4% own a computer. By our sum, phones are about 9 times as common as computers in Nigerian homes.

So start where your child already is:

• ScratchJr is a free app for tablets and some phones, for children aged about 5 to 7. Children snap picture blocks together to make characters move and tell stories.
• Scratch is free on the web and suits children aged about 8 to 16. It runs in a phone or computer browser, though a bigger screen helps.
• Code.org has free courses, the same kind used in the 8-hour study above.
• No screen at all? Play "robot" at home. Your child gives you step-by-step directions to walk from the door to the kitchen. If a step is wrong, you bump into the chair, and they have to fix their "program". That's real coding thinking, and it's free.

Tips that make coding lessons work

1. Little and often. The 8-hour study used two short lessons a week. That's easier to keep up than one long lesson a month.
2. Let them get stuck. Don't fix the mistake for them. Ask, "Which step went wrong?" The struggle is where the learning happens.
3. Ask them to explain. "Tell me what your program does, step by step." If they can explain it, they understand it.
4. Keep AI out of the early stages. If AI writes the code, your child skips the thinking. Our article on what AI is doing to children's minds explains why.
5. Make it fun first. Games and stories keep children going. Exam-style coding can come later.

In a world full of AI, children who can give clear instructions, test them and fix their mistakes will be in charge of the tools, not the other way round. That's worth a couple of hours a week.

If you teach coding or digital skills, you can run live classes and sell your own courses on Scholarleveling. Parents get a weekly code to follow their child's progress.
