Do Children Learn by Explaining What They Understand?

A correct answer and an unfinished question

In this imagined scene, a child sits at the kitchen table with a maths problem. He puts the right number in the blank, and his father is about to close the notebook. But the child says a friend reached the number another way. “How did you know?” asks his father. He begins answering, stops and rearranges the small counting pieces. For the first time, the task is not finding a new number but examining the route to the old one.

We might read this pause as failure: did he not know the answer a moment ago? Yet the new question asks something different. Producing an answer and explaining why it works may overlap without being identical. The pause may reveal a missing link or simply difficulty expressing it. Asking for an explanation should therefore not become a quick judgment of intelligence, honesty or effort.

This article concerns self-explanation: a learner’s attempt to clarify for themselves the meaning of what they read or the reason for a step they take. The aim is neither a permanently classroom-like home nor requiring children to explain every movement to deserve praise. The narrower, more useful question is when explanation adds to learning and how to allow that without turning knowledge into a performance before an audience waiting for a stumble.

Opening questions

• Does repeating a lesson’s words equal understanding their relationship?
• When does explanation help apply an idea to a new problem?
• Can explanation strengthen a mistaken account?
• How do we invite children to clarify their ideas without making them defendants?

1. From repeating a phrase to building a relationship

Take a hypothetical educational example. A child says plants need water and can repeat the sentence as heard. Asking what this means for placing a plant or following its condition moves towards connections between the statement and a situation. Repetition alone proves neither absent understanding nor all of understanding. A child can remember correct words, grasp some meaning behind them and remain unclear about other parts.

In Micheline Chi and colleagues’ 1994 study, fourteen eighth-grade students were asked to self-explain while reading about the circulatory system, and compared with ten students who read the text twice without that request. The first group gained more on the later test. This was a small experiment with specific content, not proof that all lengthy talk improves all learning. Original paper.

The practical distinction concerns what words do. “Because the rule says so” may name an authority without showing a relationship. A short sentence such as “I kept both sides equal” may begin an explanation if the child can indicate its meaning. Word count is not the only criterion. A long explanation may circle the question, while a gesture with a precise word reveals something important.

Children need not invent knowledge from scratch. Reading a worked example, they can ask why one step follows another and connect it with existing knowledge. Where required information is missing, direct explanation helps. Leaving children struggling when we have an appropriate clarification is no educational heroism. Self-explanation’s value lies in what learners add to information, not in denying all assistance.

Imagine a father showing a child how to fold paper into an envelope. The child can copy the movements and finish the shape, yet not know which fold keeps the edge closed. The father could ask them to point to what prevents opening, then try another sheet together. This is our teaching example, not a documented experiment here. It distinguishes successful imitation from understanding a particular step’s function.

Fairness also allows multiple forms of expression: drawing, arranging objects, a brief description or a counterexample. We propose no diagnostic test for learning difficulties or claim these means equivalent across every age and task. The point is not always to confuse an idea’s quality with eloquence. When understanding a relationship is the aim, “Show me” can be more open than insisting on one verbal formulation.

Explaining to another also differs from explaining to oneself. A child may focus on persuading a listener in one and organising understanding in the other. Both can coexist, but an audience is not assumed necessary for benefit. A small margin note or silently tracing a step may suffice, followed by telling us only what remains unclear. Not all learning needs public performance.

If a child says, “I do not know how to explain,” reduce the task. Instead of the whole lesson, ask about one transition: what changed between these steps? What information did you use here? This is a proposal for designing conversation, not a guaranteed formula. Choose the question for the material and allow the answer to begin shared work rather than end an exam.

2. What does it mean for understanding to transfer?

A child may succeed because a problem exactly resembles a previously seen example. Move the blank or reorder the information, and guessing returns. “They forgot” may be insufficient: perhaps the procedure’s form was memorised more than the relationship allowing change was understood. Research therefore examines transfer of learning: can acquired knowledge be used in a different task, and how different?

Bethany Rittle-Johnson’s 2006 study involved eighty-five children in grades three to five, aged eight to eleven, solving mathematical-equivalence problems. Conditions varied direct instruction versus inventing a procedure, and self-explanation prompts versus none. Instruction and explanation helped children learn and retain a correct procedure; explanation enhanced transfer, but no greater improvement appeared on an independent measure of conceptual knowledge. Researcher’s original abstract.

This prevents two hasty slogans: direct instruction always kills thought, and merely asking “explain” develops every dimension of knowledge at once. We can offer a clear example and ask children to explain part of it. We should also ask which measure actually improved, instead of treating “understanding” as one name for every possible performance.

In our own arithmetic illustration, we put three pieces on each side and ask how to maintain equality after adding one to a side. The child can suggest adding another opposite it, then count to check restored equality. What matters is identifying the relationship to preserve. This neither replaces a school curriculum nor reproduces the study procedure; it clarifies asking for a reason.

We can make a small change after explanation. If an idea was learned from one drawing, ask whether it remains when the paper turns or the colour changes. Know beforehand what changed and what stayed; otherwise we may create a harder new task and label difficulty a transfer failure. Fair comparison begins with specifying the demand, not preparing a surprise to confuse the learner.

Knowing a procedure also differs from knowing when it applies. A child may remember steps for sorting by length but need the criterion to avoid sorting by colour in another question. No classification lecture is required, only the ability to identify the property used. This is a logical distinction within the task, not assumed to test general intelligence.

When reviewing a result, keep success proportionate. Solving a new problem gives useful evidence for that problem and similar ones, not permission to declare mastery of the whole field. One setback likewise erases no prior learning. The picture develops through multiple attempts and questions, varying with time, presentation and prior knowledge. A small home exercise should not become a permanent identity.

This can also refine praise. Instead of only calling the child a genius, name what happened: “You noticed the problem’s form changed but kept the same relationship.” This suggested conversational wording is not a new result from the study. It returns attention to a revisable action and leaves room for the child to say another part remains unclear.

Nor must we ask after every answer. Practice aimed at speed in a familiar procedure may have another purpose. Pause over one step, then return to practice. Questions help when serving a known aim and burden when they become a routine condition nobody knows why they repeat. Learning requires choosing means, not applying one ritual everywhere.

3. Explanation directs attention without preserving everything

We may assume that children who explain a toy remember all its details better. Yet understanding movement’s mechanism is not remembering colours or every decoration’s location. Directing a question towards one relationship chooses what learners should seek. Ask what improved before calling a teaching method universally better.

Cristine Legare and Tania Lombrozo’s 2014 research comprised two studies of children aged three to six and a mechanical toy. Knowledge of functional and mechanical relationships was compared with memory for causally irrelevant perceptual details. Explanation benefited causal learning and generalisation, but did not improve memory for unrelated details and could impair it in younger children. In the second study, responses were classified by whether they contained explanation; its design should not be equated with experimental assignment in the first. Authors’ abstract.

This does not mean colours never matter or that forgetting a colour guarantees understanding the mechanism. It concerns the studied measures and task. Our editorial lesson is to match question and purpose: ask about movement to understand it, and do not treat that answer as also answering a question about pictorial details.

Imagine an activity with paper balls and simple, safe tracks. We might ask which part made a ball change direction, then later ask about the track’s shape. Both questions are valid but different. Misdescribing a barrier’s colour does not immediately show failure to understand its effect; describing its colour accurately does not establish understanding of the turn. Evaluation becomes fairer by specifying what we seek.

Explanation may also become more persuasive than it deserves. Caren Walker and colleagues’ 2017 study involved 114 five-year-olds across three experiments. When a hypothesis covering more observations competed with one consistent with prior knowledge, children prompted to explain more often based generalisations on prior knowledge. This does not make explanation wrong; it reveals the influence of what learners bring to a task. Research page at the authors’ laboratory.

Fluent explanation alone is therefore no reason to celebrate. Return to the example: does the account fit what happened? What observation might require revision? A linguistically coherent statement may lack appropriate evidence. We do not ask children to doubt every word, but teach the distinction between narrating a reason and having one that withstands examination.

Hypothetically, a child thinks a piece worked because it was red. Instead of repeatedly asking them to defend colour, compare controlled cases where colour differs while the relevant property remains, if the toy permits. We may discover the activity cannot isolate the factor at all. Acknowledging that limit then belongs to learning, rather than being a flaw concealed by a ready answer.

The adult’s role is not waiting for error and declaring victory. They can help formulate a testable question and show where more information is needed. Correction should address the relationship or step, not the child’s worth. This is our proposed ethical and educational manner of interaction; we do not claim the studies measured every detail of it.

4. When is explanation worth its time?

A question can be sincere and useful yet badly timed: a tired child wants to finish homework, a task requires unknown prerequisites, or a hurried adult demands a long account. A good method alone cannot repair a badly chosen moment. We must assess what conversation can achieve now and allow stopping and returning.

In research published in 2013, Katherine McEldoon, Kelley Durkin and Bethany Rittle-Johnson compared self-explanation with additional practice and a control group among sixty-nine children in grades two to four. Benefits were clearer against the control group, but smaller and limited to some measures against extra practice. The comparison accounted for activity time, not just problem count. Researchers’ abstract.

These limits help decisions rather than abolish explanation. What does a minute explaining gain compared with a clearer example, practice, rest or correcting information? The study gives no timetable for every family, but prevents treating time as free and more talking as an automatic gain.

A serious objection: is asking for explanation a disguised exam?

Children may hear “Explain to me” as “Prove you did not guess,” especially if asked only after errors. This is a conversational possibility to notice, not a diagnosis of every family. Clarify the purpose: “I want to know which step needs explaining; you need not say it like the book.” Its truth depends on what follows the answer, beyond gentle wording.

Interrupting every word or rushing to fill gaps returns explanation to ourselves. Refusing needed help turns independence into isolation. Between them lies simple work requiring attention: listen to one idea, ask about what we did not understand, provide information when needed and leave a chance to use it. This does not require endless dialogue.

Avoid competitions between children over explanatory eloquence. One may enjoy talking, another drawing, and another need time to organise a sentence. Do not automatically convert these differences into understanding scores. Ask about the task, allow suitable means and avoid personal comparisons that help no one identify the next step.

In the light of the Quran and Islamic wisdom

At the end of Ta-Ha, verse 114, Allah says: ﴿وَقُل رَّبِّ زِدْنِي عِلْمًا﴾TRANSLATION OF THE MEANING · COMPLETE VERSE 20:114So Exalted is Allah, the True Sovereign[1]. Do not hasten to [recite] the Qur’an before its revelation to you is concluded[2], and say, “My Lord, increase me in knowledge.”Translation notes: [1] Of everything in existence. [2] Prophet Muhammad (ﷺ) was eager to recite the Qur’an while it was being revealed, so Allah Almighty told him to avoid being in haste in order to learn them before the verses are properly delivered; rather, listen to them attentively.Rowwad Translation Center · QuranEnc · v1.0.20. The request occurs in the context of a prohibition against rushing to receive the Quran before revelation is complete. Al-Saadi explains eagerness for knowledge and seeking its increase from Allah, drawing lessons about patience in receiving speech and understanding a question before answering. Complete verse and commentary.

We derive no experimental proof of self-explanation from the verse and do not equate receiving revelation with schoolwork. The Quranic context has its meaning; psychological research has its tools and limits. Our reflection is that seeking knowledge allows acknowledgement of incomplete understanding, and patience in asking and answering can protect dialogue from hasty judgment.

An adult asking children to explain can begin willing to learn something about their own question. The obstacle may be an unfamiliar word rather than the relationship we assumed unknown. The adult may discover a hurried explanation or ambiguous example. This does not diminish their standing; it clarifies responsibility, allowing revision of their method rather than making every difficulty a learner’s deficiency.

Another editorial reflection distinguishes humility from pretending ignorance. Parents need not hide knowledge to allow learning, or claim an answer to everything to preserve respect. They can say, “I know this step and will explain it; this detail needs checking.” Honesty and knowledge connect without claiming that explanation’s quantity alone creates good character.

Practical applications: one question with a purpose

Begin with a small task whose prerequisites the child partly knows, and explain why you ask: “Choose one step and show me why you did it.” Allow words, drawing or arranged objects as suits the activity. This is an editorial practical framework, not a programme whose steps were jointly tested in the cited studies.

After the answer, identify what you understood before correcting: “I understood that you used the number of pieces; is that what you mean?” Children can then correct your understanding, preventing a response to an account they never gave. Return to the example: where do we see the relationship described? Supply missing information clearly rather than prolonging questions they cannot answer.

Change one thing in the next attempt without making it a punitive surprise. Reorder elements while preserving the rule, then ask what stayed constant. If it fails, retain the specific observation: “This transition needed explanation.” Do not turn it into “You only understand by memorising.”

At the end, ask what changed in the idea, not how much was said. Children may discover a rule used in the wrong place, or a reason known but not named. No clear change may emerge. We need not invent success to justify time; what we learned can guide simpler explanation or better practice later.

To make listening actionable, imagine three answers to one task. In a hypothetical card-sorting activity, we ask for shapes with four sides. One child says, “I put it here because it looks like this one.” We do not yet know the resemblance intended, so ask them to point. Another says, “Because it has four sides,” but includes a five-sided shape. The correct phrase is insufficient; count sides together. A third misnames the shape but counts its edges and sorts new examples by the condition. Distinguish correcting terminology from learning the criterion. These editorial cases illustrate different next steps, not diagnostic categories of children.

In the first, the evidence heard is ambiguous: the child may have the criterion without stating it, or use another resemblance. The second reveals a difference between stated rule and execution, perhaps helped by revisiting one card. The third gives limited evidence of applying the criterion alongside a linguistic need for a more precise name. None alone judges all understanding. Each gives clearer direction than repeating the question louder or demanding one model answer from everyone.

Parents can keep a short observation rather than a grade: “Used the number of sides when the card colour changed; needed help counting one shape.” This describes what was observed and what remains, preventing impressions of personality from replacing attention to work. Next time, begin with what needs clarification instead of a comprehensive exam on everything before. If performance differs, ask how the task differed before assuming general decline.

Children can learn a simple review form: “I thought… then noticed… so I will change…”. Do not require it in every activity or give new words to memorise instead of thinking. Its possible benefit is organising a description of revision when it actually occurs. An honest answer may be “I still do not know why the result differed.” Then seek the missing information. Dialogue’s value lies in making knowledge’s boundaries visible and workable, not producing a beautiful ending regardless of evidence.

Leave home times when every game does not become a lesson. Not every block construction invites transfer testing; not every passing question is a research project. Choosing a limited learning pause helps preserve its aim and end clearly. The article’s symbolic cover, with blocks and paper, evokes building meaning; it represents no particular experiment or evidence of a result.

Conclusion: letting children hear their ideas taking shape

Explanation may help children connect existing and new knowledge and apply a relationship elsewhere. It guarantees no complete understanding, is no permanent replacement for instruction and practice, and may direct attention to some properties at others’ expense. A question’s value therefore rests in its purpose, timing and how we listen to the answer.

The father returns to the notebook without demanding a lecture. He points to one step and waits. When the child rearranges pieces and revises the account, he need neither call him a genius nor accuse him of having known nothing. It is enough to see the idea becoming clearer and leave a door open to the next question.

Questions that stay with us

• Do I ask for explanation to understand thinking or find an error?
• What distinguishes remembering a procedure from knowing when it applies?
• What observation might make me revise a convincing explanation?
• How can I leave children the right to pause, ask and return?
