Coding gives children a practical way to turn a goal into steps, try those steps, and revise them when the result is not what they expected. That plan–test–debug cycle overlaps with important problem-solving skills. Research reviews report average benefits on measured problem-solving and computational-thinking outcomes, but coding is a useful learning opportunity—not a guarantee that every child will become better at every kind of problem.
What problem-solving practice does coding provide?
Consider a child who wants a character to cross a screen and avoid an obstacle. The child has to decide what should happen first, break the goal into instructions, put them in an order, and see whether that sequence works. If the character turns too soon or hits the obstacle, the child can inspect the instructions, identify a likely error, and change the plan.
This makes an otherwise abstract plan visible and testable. Coding can give children practice with:
- Decomposition: breaking a larger goal into smaller tasks.
- Sequencing: arranging instructions so they produce the intended result.
- Testing and monitoring: comparing what happened with what was expected.
- Debugging and revision: locating an error and trying a revised solution.
The American Academy of Pediatrics describes computational thinking as breaking a problem into steps a computer can follow. These activities provide a plausible route from coding practice to problem-solving practice; they do not establish that each activity independently improves general intelligence or every academic skill.

What does the research say about problem-solving gains?
A 2024 meta-analysis by Montuori, Gambarota, Altoè and Arfé reported its largest cognitive effect estimate for problem-solving: dppc2 = 0.89. The same analysis reported estimates of 0.36 for planning, 0.17 for inhibition and 0.20 for working memory. Its systematic review included 19 studies with 1,523 participants; 11 studies were included in the meta-analysis. These are averages across the interventions and measures in the analysis, not a forecast of what an individual child will gain.
A separate 2019 meta-analysis by Scherer, Siddiq and Sánchez Viveros examined transfer from learning computer programming. Across 105 studies and 539 effect sizes, it reported an overall transfer estimate of g = 0.49. The estimates were g = 0.75 for near transfer—applying learning to a related task—and g = 0.47 for far transfer to a more distant skill or setting. These findings make transfer beyond coding plausible, but they do not show that every child will gain all-purpose problem-solving ability.

Results depend on what researchers measure. Success at a coding challenge or a related computational-thinking assessment is not the same as demonstrating improvement in an unrelated school subject or everyday situation. A 2022 OECD review, for example, describes a Scratch course study involving 49 students aged 10–11 that found no significant difference in measured problem-solving skills after the intervention. Their self-confidence ratings also rose nonsignificantly.
Why the way coding is taught matters
A 2023 meta-analysis of 28 empirical K–12 studies by Xu, Wang and Wang reported an overall computational-thinking effect of ES = 0.72 (95% CI [0.60, 0.83]). In its analyses of teaching approaches, scaffolding had an estimate of ES = 1.84 and problem-based programming ES = 1.14. Those subgroup estimates describe findings in that synthesis; they are not guaranteed outcomes for a particular classroom, child or program.

The practical implication is to look beyond whether an activity involves code. Children need a meaningful challenge and enough support to make progress while still doing some of the thinking themselves. Useful activities let them form a plan, build or enter it, observe what happens, explain the result and revise their approach. Prompts, worked examples and feedback can help beginners; gradually reducing that support gives children more responsibility for choosing and testing solutions.
The AAP summary also reports stronger results in programs featuring peer collaboration. When appropriate, children can explain their reasoning, compare possible solutions and build something together. Collaboration should support the child’s own decisions rather than replace them.

Choosing an activity or tool for a child
No single language, robot or coding platform is established as best for every child. Start with the learner and the kind of problem-solving practice the activity offers, rather than choosing by product name alone.
- Match the entry point to the child. Tangible activities or block-based coding can make instructions easier to see and manipulate; older or more experienced learners may enjoy more open-ended virtual coding. These are options, not strict age rules.
- Check for a real problem to solve. A project should give the child a reason to plan and revise, not just follow a fixed sequence without making decisions.
- Look for appropriate support. Examples, hints and feedback can help a child get started. Stronger activities also leave room for experimentation and gradually greater independence.
- Make room for explanation and choice. Ask what the child expected, what actually happened and what they might change next. Invite collaboration when it fits the activity.
- Separate coding progress from transfer claims. If the goal is broader problem-solving, look for evidence about a separate problem-solving measure—not only whether children learned to complete the coding task.
Hands-on options can include tangible coding activities and robots. The OECD review describes the seven-week Coding as Another Language curriculum using the KIBO robot, as well as research on ScratchJr and tangible coding. These examples show that children can practise sequencing and debugging in different formats; they do not establish that one tool is superior.

Learning to code and “coding to learn” are different claims
Learning to code means acquiring programming knowledge and skills. Coding to learn is the idea that programming practice may also support other abilities, such as planning or problem-solving. A child can make progress at coding without that progress automatically transferring to unrelated tasks. The reviews suggest that transfer can occur on average, but outcomes vary with the activity, teaching, age and assessment.
