A young child points at a puddle and says, “Car splash.” An adult can respond in several ways. “Yes.” “What colour is the car?” “Say: the car splashed through the puddle.” Or the adult can take the child’s meaning seriously and return it in a slightly richer form: “The car splashed through the big puddle.” The child’s idea remains the centre of the exchange, but the language around that idea has grown.
That tiny move is easy to underestimate. Children do not learn grammar only from formal explanations. They spend years hearing how other people package meaning into phrases and sentences. When an adult sensitively recasts an incomplete or inaccurate utterance, extends a short phrase, repeats a useful sentence pattern in several contexts, and invites the child to try language that is just beyond what they currently produce independently, the adult is making the structure of language available at the moment it has a communicative purpose.
The Education Endowment Foundation’s current Early Years Evidence Store describes teaching and modelling language as an intentional approach in which educators use language structures to show children how words can be combined into sentences and encourage increasingly complex language as understanding grows. EEF rates the overall evidence behind the approach as strong, while also making an important qualification: the evidence does not isolate one magic micro-technique. Recasting, questioning, sequencing, recalling, repetition and imitation often appear as parts of wider language-rich practice. The correct claim is therefore not “recasting alone guarantees a language gain.” The defensible claim is that deliberate modelling of increasingly useful sentence structures is a well-supported part of early communication and language teaching.
This article owns one narrow job on eduKateSG: responsive adult language expansion in everyday early-years interaction—recasting, extending and modelling a child’s intended message so that grammar, sentence structure and expressive language become more available without replacing the child’s communicative agency. It does not own vocabulary instruction, shared-book reading, targeted oral-language intervention, speech-language therapy or general social-skills teaching. Those are neighbouring mechanisms.
The useful question is not, “Did the adult use a longer sentence?” It is: did the adult return language that the child could connect to the meaning they were already trying to express, and did the interaction leave the child with a better route for saying something next time?
The 50-second answer
Language expansion works when an adult listens for the child’s intended meaning, responds to that meaning, and then supplies a slightly more complete or precise language form. A child says, “Dog running.” The adult replies, “Yes, the brown dog is running across the grass.” A child says, “He goed home.” The adult replies naturally, “He went home after lunch.” A child says, “Because rain,” and the adult expands, “They stayed inside because it was raining.”
A useful route is:
- Follow the child’s meaning first. Language teaching works better when the child is genuinely trying to communicate.
- Model one step beyond the child’s current production. Do not turn every utterance into a miniature lecture.
- Keep the corrected or expanded form conversational. Recasts should usually sound like a response, not a public error announcement.
- Repeat useful structures across different contexts. A pattern becomes more learnable when it reappears with varied content.
- Invite production without forcing parroting every time. Sometimes imitation is useful; sometimes the adult should simply model and continue.
- Build from phrases toward connected sentences. Add who, what happened, where, when, why or how only when the meaning needs it.
- Use gestures, pictures, objects and action when language alone is too abstract.
- Monitor the child’s independent language. The endpoint is not adult eloquence; it is child control.
The shortest principle is: hear the child’s idea, give it a stronger linguistic shape, then leave enough conversational space for the child to keep owning the exchange.
1. Start with communicative intent
A child’s short utterance is not merely an incomplete sentence. It is an attempt to make something happen socially: share an observation, request help, tell a story, protest, predict, joke or explain. Language expansion is strongest when the adult protects that intention.
If a child says, “Baby crying,” the adult might respond, “Yes, the baby is crying because she dropped her toy.” The adult has acknowledged the observation before adding grammar and cause. By contrast, “Say it properly: the baby is crying” may shift the interaction from communication to performance before the child has experienced being understood.
This does not mean correctness is unimportant. It means correction is embedded in a meaningful response.
2. Recast without turning the conversation into error hunting
A recast gives back a corrected form while preserving the original message.
Child: “He goed outside.”
Adult: “He went outside to find the ball.”
The adult has supplied the conventional past tense without requiring a grammar explanation. The child hears the form in the exact semantic slot where the error occurred.
Recasts are especially useful for errors the child is developmentally ready to notice or forms that recur often. They become less useful when every sentence triggers a correction. Constant recasting can make adults sound as if they are editing rather than listening.
The educational judgement is selective: which language feature is worth making more visible right now?
3. Extend a short utterance by one useful information unit
Extension is different from merely correcting grammar. The adult adds meaning.
Child: “Train fast.”
Adult: “The train is moving very fast through the tunnel.”
The expansion adds an article, auxiliary verb, adverb and place phrase. Yet the sentence is still recognisably about what the child noticed.
One-step extension is often enough. If the adult responds with a forty-word description, the linguistic distance may become too large for the child to map their own utterance onto the model.
A good expansion is richer without becoming unrelated adult prose.
4. Match the expansion to the child’s current language level
A two-word speaker and a child who already produces complex clauses need different models.
For a child saying “Mummy shoe,” “Mummy’s shoe is wet” may be useful. For a child who already says “Mummy’s shoe got wet,” the adult might add cause: “Mummy’s shoe got wet because she stepped in the puddle.”
The principle resembles good scaffolding elsewhere in education: enough novelty to stretch the learner, enough familiarity to preserve the route.
If nearly every word and structure is new, the adult has produced exposure, not necessarily an accessible model.
5. Use grammar as a meaning tool
Young children do not need grammar to be introduced only as terminology. They need to experience what grammar lets speakers mean.
Compare:
- “Dog chase cat.”
- “The dog chased the cat.”
- “The cat chased the dog.”
- “The dog was chased by the cat.”
Small structural changes alter agency, time and focus. An educator can make those meanings visible through real events, toys, pictures and stories.
The purpose is not early grammar parsing for its own sake. It is to help children discover that sentence structure carries relationships.
6. Model subject–verb completeness when fragments dominate
Young speakers often communicate effectively with fragments because shared context supplies the rest. School language increasingly demands more explicit sentences.
During play, “More blocks” may work perfectly. During explanation, the child may need “I need more blocks because the tower is not high enough.”
Adults can model this movement without treating conversational fragments as defective. The task determines how much explicit language is needed.
A useful question for educators is: does this child need a fuller form to carry the next kind of thinking?
7. Expand noun groups to improve reference
“Car” can become “the red car,” then “the small red car with the broken wheel.” Noun expansion helps children identify exactly which person, object or idea they mean.
During sorting, an adult might say, “You chose the triangle” and later, “You chose the small blue triangle.” In a story, “the girl” can become “the girl who lost her umbrella.”
This language is not decorative. It teaches children how speakers manage reference when several possibilities exist.
8. Expand verbs to make events more precise
Children may rely on general verbs such as go, do, make, get. Adults can model more precise alternatives in context.
“The water goes down” might become “The water drains through the hole.” “He made it fall” might become “He knocked the tower over.”
The goal is not to replace every ordinary verb with a sophisticated synonym. Precise verbs are useful when they clarify the action or mechanism.
Vocabulary and grammar meet here: the new verb has to fit a sentence pattern the child can use.
9. Add place where spatial language matters
“Bear hiding” can become “The bear is hiding under the table.” Then the adult can contrast under, behind, beside, between using the same play scene.
Relational words are powerful because they organise concepts as well as sentences. The child is learning a linguistic form and a spatial relationship at the same time.
Physical objects make these meanings easier to inspect. Move the bear and say the sentence again. The language changes because the relation changes.
10. Add time to support sequence
Young children telling stories often produce a chain of events without clear temporal language: “We eat. We go park. Rain.”
An adult can model, “After we ate lunch, we went to the park. Then it started raining.”
Words such as before, after, then, later, first, finally help organise experience into sequence. They also prepare children for narrative and explanatory language in school.
The adult should connect the time word to an event the child understands rather than teaching it as an isolated definition.
11. Add cause when the child is ready to explain
“Tower fell” can become “The tower fell because the bottom blocks moved.”
Cause clauses invite children to move from event naming toward explanation. This is valuable across play, Science and story discussion.
But adults should not insert causal language where the relation is speculative. “She is sad because she lost the toy” is appropriate if the story supports it. “She is sad because she doesn’t like him” may invent motive.
Language expansion should improve reasoning, not merely grammatical complexity.
12. Model conditional language in real choices
“If we put the heavy block on top, the tower might fall.”
Conditional language lets children represent possibilities rather than only what has already happened. It supports planning, prediction and later scientific reasoning.
During play, adults can model if, unless, when, might, could. The meaning should remain concrete enough for the child to test.
“Let’s see if that happens” turns the sentence into a prediction rather than an adult fact.
13. Use repetition with variation
Hearing one model once is exposure. Hearing a useful structure repeatedly with different content can reveal the pattern.
“The car is under the bridge.”
“The rabbit is under the chair.”
“The spoon is under the napkin.”
The child can begin to abstract X is under Y from the changing examples.
Variation matters. If the adult repeats the exact same sentence ten times, the child may learn the phrase as a chunk without learning how its parts can be recombined.
14. Return to the same pattern on another day
Language learning is not confined to one interaction. A structure that appears during block play can return during a story, snack routine or outdoor activity.
Yesterday: “The tower fell because the base was narrow.”
Today: “The path is slippery because it rained.”
Tomorrow: “The ice melted because it got warm.”
The repeated causal frame becomes increasingly portable.
This is one reason curriculum planning matters even in conversational teaching. Spontaneity and intentional recurrence can coexist.
15. Imitation can help, but it should not consume every turn
Sometimes it is useful to ask a child to repeat a model, especially a new phrase, pronunciation or sentence structure.
Adult: “The caterpillar crawled across the leaf. Can you say, ‘crawled across the leaf’?”
But if every expansion ends with “Say that,” the child can become a repeater rather than a conversational partner.
Use imitation selectively, then ask the child to use the pattern in a new example. Transfer matters more than echo.
16. Narrate action when the child has language to attach to it
During play, an adult can narrate: “You’re pouring the water into the narrow cup. Now it’s overflowing.” This supplies verbs, prepositions and event language at the moment the child can see the referent.
Narration is useful when it follows attention. Talking continuously about whatever the adult notices can become linguistic wallpaper.
A strong educator watches first, then chooses language that labels or structures what the child is already attending to.
17. Use parallel talk to model the child’s own actions
“You pushed the long block underneath. Now the bridge is stronger.”
Parallel talk gives language to the child’s action without demanding an immediate response. It can be especially supportive for children who are hesitant speakers.
After several models, the adult might pause: “You put this one…” and let the child complete the sentence.
The transition from hearing to completing to independently producing is gradual.
18. Use self-talk to make adult language purposeful
The adult can verbalise their own action: “I’m looking for the lid that fits this box. This one is too wide, so I’ll try the smaller lid.”
This exposes first-person language, comparison and causal reasoning.
Self-talk becomes less useful when it turns into a constant commentary unrelated to the child’s focus. The model should offer language structures the child can plausibly reuse.
19. Connect spoken language to gesture and action
Words such as behind, twist, enormous, squeeze, before become easier to interpret when gesture or action carries part of the meaning.
The adult can say “twist the lid” while demonstrating the movement. Later, the gesture can fade and the word remains.
EEF’s evidence summary notes that combining verbal practice with physical strategies, props and pictures can strengthen language teaching. The educational mechanism is straightforward: several cues converge on the same meaning.
20. Use pictures to support sentence building, not only naming
A picture of a child feeding ducks can produce more than “duck.” Ask, “What is happening?” Then model or expand: “The child is throwing bread to the ducks.” Add cause or prediction if appropriate.
Pictures are valuable because the event remains visible while the sentence is constructed.
Move beyond object labels when the child is ready. Language development depends on relations among people, actions and ideas, not only nouns.
21. Recall past events because the context is no longer visible
Talking about yesterday’s trip creates a different language demand from commenting on what is happening now. The child has to reconstruct the event without pointing at it.
Adult: “What happened after we saw the fish?”
Child: “Big shark.”
Adult: “After we saw the fish, we went to the big shark tank.”
Recall conversations support sequence, tense and narrative organisation precisely because the original scene is absent.
22. Discuss future events to practise possibility and planning
“What do we need before we go outside?” “What might happen if the clouds get darker?”
Future talk introduces modal language and planning structures. It also provides a meaningful reason to use will, might, could, need to, before.
The adult can later revisit the prediction: “You thought it might rain. What actually happened?”
Language becomes part of monitoring thought across time.
23. Use stories as one context, not the only context
EEF highlights stories and interactive reading as strong settings for language modelling. Books provide repeated, coherent language and shared reference.
But everyday routines, play and problem solving matter too. A child who only hears complex language during story time may not spontaneously use it while building, negotiating or explaining.
The aim is a language-rich day, not a single language-rich activity.
24. Keep questions from crowding out modelling
Adults often try to stimulate language by asking many questions. Questions create opportunities to respond, but they can also make the child feel examined.
Balance questions with comments and models.
Instead of:
“What is that? What colour? What is it doing? Where is it going?”
Try:
“That tiny green beetle is crawling underneath the leaf. I wonder where it’s going.”
The second version offers vocabulary and syntax while still inviting participation.
25. Use genuine questions when the adult does not know the answer
“What are you building?” is genuine if the child designed it. “What colour is this?” is often a test if the adult clearly knows.
Both types have a place, but genuine questions change the social relationship. The child has information the adult wants.
This can increase the complexity of what the child tries to say because the utterance now has a real informational purpose.
26. Let silence do some of the teaching
After modelling a sentence, pause. The child may imitate, extend, disagree or move on.
Adults who fill every silence remove opportunities for children to formulate language. A few seconds can feel long to an adult and entirely necessary to a young speaker.
Wait time should be sensitive to the child. The goal is not a ritualised delay but enough space for language production.
27. Recast pronunciation carefully
A child may say a word in a developmentally expected or language-influenced way. The adult can model the conventional classroom pronunciation naturally without forcing repeated public correction.
Child: “pasghetti.”
Adult: “Yes, spaghetti. We’re having spaghetti for dinner.”
Persistent speech-sound concerns may require specialist assessment. Everyday recasting is not speech therapy.
28. Distinguish dialect difference from language error
Children may use grammatical forms from a home dialect or variety of English. Educators should not treat every difference from formal school English as deficiency.
The teaching job can be additive: “That is how you say it at home; in this kind of school sentence, we might say…”
Language expansion should widen repertoire without devaluing identity.
29. Use home languages as conceptual support
A multilingual child may have the idea in another language before possessing the English structure. Allow the concept to remain visible through gesture, home-language words, drawing or objects, then model the English form.
The aim is not to erase the first language. It is to add another route for expressing known meaning.
Families can also model rich syntax in the language they use most naturally at home. Strong conversation is not valuable only when conducted in English.
30. Notice when sentence complexity exceeds conceptual understanding
A child can repeat “because it evaporated due to temperature” without understanding evaporation. Linguistic sophistication can disguise shallow concept knowledge.
After modelling a complex sentence, check whether the child can demonstrate or explain the relation in another way.
Language should make thinking communicable, not create a decorative shell around it.
31. Notice when conceptual understanding exceeds sentence control
The reverse problem is equally important. A child may show through action or drawing that they understand a sequence but speak in short fragments.
That is exactly where language expansion is useful. The adult does not need to reteach the concept. They need to help the child package what is already understood.
This distinction prevents educators from underestimating children whose expressive language trails their reasoning.
32. Move from adult expansion to child self-expansion
At first, the adult supplies the richer form. Later, use a prompt: “Tell me a little more.” “Where did it happen?” “Can you join those two ideas?”
Eventually the child should add the information without the prompt.
This is the transfer path. If every complex sentence exists only after adult completion, the interaction is supportive but the language structure is not yet independently controlled.
33. Use contrast to make a structure easier to notice
Children often learn a language pattern more clearly when two nearby examples differ in one meaningful way. During play an adult might say, “The rabbit is inside the box. Now the rabbit is outside the box.” In a story conversation: “Yesterday he went to the shop. Today he goes to school.” The purpose is not to deliver a grammar lecture. Contrast makes the relationship audible.
Keep the contrast small enough that the child can notice what changed. If vocabulary, sentence length and topic all change at once, the target structure disappears inside novelty. A useful contrast isolates a meaningful distinction and then returns it to ordinary conversation.
34. Give children reasons to use longer language
A child rarely needs a complex sentence to answer a question that can be solved by pointing. If educators want explanation, sequence or qualification, the activity must create a communicative need for it. A mystery bag may require description so a partner can identify an object. A construction problem may require cause: “It keeps falling because…” A retell may require sequence: “First… then… finally…”
This is an important design principle. Adults cannot simply request richer language indefinitely while arranging tasks that reward one-word answers. The environment should make the target language functional.
35. Separate expressive support from factual correction
Sometimes the child’s sentence is linguistically weak but factually right. Sometimes the grammar is good but the idea is wrong. These need different responses.
Child: “The ice melt because hot.” The adult may expand, “The ice melted because it got warmer.” If the child instead says, “The ice melted because it became colder,” the educator must address the scientific relation as well as the sentence.
Keeping those layers separate helps feedback remain precise. Language expansion should not accidentally validate a misconception merely because the sentence form improved. Equally, conceptual correction should not erase an opportunity to model useful language.
36. Make the child’s independent language the progress measure
Adult-child interaction can look impressive because the adult supplies so much. To know whether learning is occurring, occasionally step back. During a fresh activity, listen before prompting. Does the child now use a past-tense form that previously required a recast? Can they connect two events with because? Do they identify a specific object with a richer noun group? Can they retell two steps in order?
A small language sample across several contexts is often more informative than counting how many times the educator used a recommended technique. Implementation matters, but the educational outcome is what the child can increasingly produce and understand.
37. Use peer conversation as a test of whether the language is becoming portable
Adult-child interaction is only one environment. A useful next step is to listen to what happens when the adult is not the conversational engine. Put two children into a shared construction, picture-sequencing or role-play problem and notice whether the target structure appears. Does a child who has heard many causal expansions tell a peer, “It fell because this one moved”? Does sequence language appear when explaining a game?
The peer context is harder because the adult is no longer supplying the linguistic frame. Success there suggests the child is beginning to own the pattern. If the structure disappears completely, bring back light adult support, model it once, then withdraw again.
38. Avoid measuring progress with sentence length alone
Longer speech can indicate growing expressive language, but length by itself can mislead. A child may produce a long string joined by repeated and while another uses a shorter sentence with precise cause, reference or tense. Better evidence asks what relations the child can now express and how independently they can express them.
Look for a widening repertoire: naming precise participants, marking past events, sequencing, giving reasons, qualifying a claim, explaining location, connecting ideas and adapting language to the listener. Language expansion is successful when children gain more ways to organise meaning, not when every utterance becomes longer.
Worked case 1 — “He fall” becomes a causal explanation
A four-year-old building with blocks says, “He fall,” referring to a toy figure. The educator replies, “He fell off the bridge.” The child repeats “fell bridge.” The educator continues playing rather than demanding a full repetition.
Later the same morning, the figure falls again because one support block moves. The educator says, “He fell because the block moved.” She asks, “Why did he fall?” The child answers, “Because block moved.” She recasts: “Yes, because the block moved.”
Two days later, during outdoor play, a bucket tips. The child says, “It fell because too heavy.” The exact sentence was never drilled. The causal frame travelled.
Worked case 2 — A multilingual child with a rich idea and a short English sentence
A child draws a picture of a family celebration and says in English, “Grandma cooking.” The educator knows from conversation with the family that the child speaks much more elaborately in another language.
She replies, “Grandma is cooking noodles for everyone.” The child adds, “for birthday.” The educator says, “Grandma is cooking noodles for the birthday dinner.”
The exchange does not treat the child as conceptually limited. It adds English structure to a detailed event the child already understands.
Worked case 3 — Too many questions reduce language
An adult trying to help a quiet child asks a question after almost every action: “What is that? What colour? Where are you putting it? Why? What next?” The child’s answers become shorter.
The educator changes strategy. She sits nearby and comments selectively: “You put the wide block at the bottom. That makes the tower steady.” After a pause the child says, “This one top because small.”
The adult expands: “Yes, the small one can go on top because it is lighter.” The child has produced more language after the interrogation reduced.
Worked case 4 — Recasting without humiliating correction
A five-year-old tells a group, “We goed to zoo and seeed monkeys.” The teacher wants to support past tense but does not interrupt the story with a grammar correction.
She responds, “You went to the zoo and saw monkeys. What were the monkeys doing?”
The child continues. Later, during a small-group retell, the teacher deliberately models several past-tense forms and invites children to complete a few sentences.
Accuracy is taught, but the original storytelling turn remains socially successful.
Practical route for teachers and early-years educators
Choose two or three language structures that matter in current classroom experiences rather than trying to correct everything. Listen to children during play, routines, stories and problem solving. When a child produces a shorter or non-standard form, respond first to meaning and return a model just beyond current production. Repeat high-value structures across varied contexts. Use objects, gestures and pictures when they make the relation clearer.
Balance questions with comments. Build recall and future talk into the week, because language becomes more demanding when the event is not physically present. Keep brief notes on what children can now say independently. If a child’s expressive language remains markedly limited despite rich interaction, discuss the pattern through the setting’s appropriate language-development and specialist pathways rather than escalating ordinary recasts indefinitely.
Practical route for learners
You do not need to repeat every adult sentence perfectly. Listen for useful ways to say what you mean. Try a longer phrase when you can: who did it, what happened, where, when or why. If someone gives your idea back in a clearer sentence, notice the part that changed. Use it later in a new situation.
Ask for words when you know the idea but cannot yet say it. Use gesture, drawing or another language to keep the meaning alive while you learn the new form.
Practical route for parents and families
Talk with the child rather than constantly testing them. If they say “big truck,” you might reply, “Yes, the enormous truck is carrying sand.” If they say “we goed park,” respond naturally, “We went to the park after lunch.” Let conversation continue.
Use ordinary routines: cooking, travelling, bath time, shopping, building, drawing. Explain what is happening and ask genuine questions. Revisit family experiences: “What happened after we left Grandma’s house?” Rich conversation in the home language is valuable too. The goal is a child who has more ways to express meaning, not a home that feels like an oral grammar examination.
Common failure modes
- Correcting every sentence until the child contributes less.
- Expanding so far beyond the child’s language that the model cannot be mapped onto the original utterance.
- Asking question after question while providing little language worth imitating.
- Treating home dialect or multilingual influence as evidence of low intelligence.
- Forcing repetition after every recast.
- Modelling sophisticated grammar without making the meaning clear.
- Using long adult monologues as “language exposure.”
- Narrating constantly without following the child’s attention.
- Teaching vocabulary labels without sentence structures that let children use them.
- Assuming a child who can repeat a complex sentence understands the concept.
- Assuming a child with short expressive language has weak conceptual understanding.
- Using shared-book language only inside book time and never across play or routine.
- Expecting transfer without repeated variation.
- Treating everyday educator modelling as a substitute for specialist assessment when a significant persistent language difficulty is suspected.
- Measuring success by adult talk rather than growth in child production.
Frequently asked questions
Is language expansion the same as correcting grammar?
No. Correction can be part of it, but expansion also adds useful meaning and sentence structure. The adult may turn “dog running” into “the brown dog is running across the grass” even though the child’s original phrase was communicatively successful.
What is a recast?
A recast is a responsive reformulation of a child’s utterance. The adult keeps the intended meaning while returning a more conventional grammatical or pronunciation form.
Does EEF say recasting alone is strongly evidenced?
No. EEF describes strong evidence for the broader teaching-and-modelling-language approach. It explicitly notes that the evidence does not identify which individual practices are most effective in isolation. Recasting is one practice used within that broader approach.
Should children always repeat the adult model?
No. Selective imitation can help, but compulsory repetition after every turn can damage conversational flow. The stronger test is whether the child later uses the structure independently.
Can this be used during play?
Yes. Stories and interactive reading are strong contexts, but imaginative play and everyday routines also create natural reasons for adults to model grammar, sequence, cause and descriptive language.
Does this replace vocabulary teaching?
No. Vocabulary gives children words and meanings; language modelling helps show how words can be organised into sentences and relations. The two mechanisms support one another.
What about multilingual children?
Use the child’s conceptual knowledge, gestures and home language as assets. Add the instructional-language form without treating another language as interference by default.
What if the child does not respond after an expansion?
The model can still be useful exposure. Do not demand an immediate performance every time. Continue the interaction and create repeated opportunities later.
When should educators seek specialist support?
When language development is persistently limited, unusual for the child’s developmental stage, or affecting participation and learning despite appropriate rich interaction, follow local assessment and speech-and-language pathways. Everyday language modelling is not a clinical diagnosis or treatment plan.
How do we know the approach is transferring?
Listen for structures appearing in new contexts without immediate adult modelling: the child independently adds cause, sequence, descriptive detail or a more complete sentence during play, storytelling or explanation.

The final idea
A child’s early sentence is not a rough draft that adults must constantly repair. It is an act of communication. Good language expansion respects that act and then quietly increases what language can carry.
The adult hears “car splash” and does not respond as a grammar examiner. They respond as a person who understood, then offers a stronger route: “The car splashed through the puddle.” Across hundreds of interactions, structures for reference, sequence, cause, condition and explanation become familiar enough to use.
That is the educational mechanism worth protecting. The adult’s language is temporary scaffolding around the child’s meaning. The success condition is not a room full of adults producing perfect sentences. It is a child who increasingly can.
