Compare acquisition theories using transcription
Connect child and caretaker language to contrasting acquisition approaches and use transcription conventions accurately.
Exam scope and assessment notes
These original lessons support study of the official syllabus; they are not Cambridge materials. Practice is self-checked and does not award Cambridge marks or grades. Extended writing and analytical essays need qualified subject-teacher review. Full timed papers and examiner-marked learner responses are not provided here. Interpret language choices in context and qualify claims about audience response.
Before you begin
Work on paper. Try each question before revealing help, and explain why your method works.
Quick readiness check
Which approach most directly highlights adult scaffolding?
What you will learn
- Explain behaviourist, nativist, constructivist and social-interactionist approaches.
- Read common transcription conventions and use them as evidence.
- Compare interpretations without treating one exchange as proof.
Compare explanations, not just names
Behaviourism highlights imitation, reinforcement and learned patterns. Nativism proposes an innate capacity for language, including Universal Grammar or a Language Acquisition Device. Constructivist approaches emphasise cognitive development and language-building from experience; social-interactionist approaches highlight interaction, support and scaffolding.
A transcript may be discussed through more than one approach. An adult prompt can provide support, while a child's novel combination may show productive pattern use. The syllabus also includes language acquisition support systems and the zone of proximal development.
Read transcription conventions first
The syllabus key includes (.) for a micropause, (1) for a one-second pause, // for overlap, arrows for intonation and brackets for context or paralinguistic features. Use the key supplied with a task; conventions can vary.
Quote turns accurately, distinguish child and adult contributions, and explain the sequence. A theory frames analysis but cannot prove causation from one brief exchange.

Pause and explain
A child repeats a form once after an adult. What is the safest conclusion?
Worked example
Invented transcript: Adult: 'Can you try it this way?' Child: 'I goeded.' Adult: 'You went?' Child: 'Went, yes.' Compare two readings.
Show the worked solution
- A social-interactionist reading may focus on the adult recast and the child's uptake.
- A constructivist reading may note the productive over-regularised pattern.
- A brief exchange cannot show which process caused durable learning.
Answer The adult recast supplies a model and the child uses it in the next turn, which is consistent with support in interaction. 'Goeded' also suggests a productive pattern. One exchange cannot establish lasting change or choose a complete theory.

Write your answer and reasoning first. Use a hint only if you are stuck. The model solution is for self-checking; your written work is not automatically marked.
In a transcript, // marks two speakers talking at once. Give one observation and one limit.
Give me a hint
The symbol identifies overlap; surrounding turns show what it may mean.
Compare my reasoning
- State that the turns overlap.
- Inspect whether the sequence suggests interruption or collaborative completion.
- Avoid deciding the function from the symbol alone.
The transcript records simultaneous speech. If one speaker completes another's phrase, it may be collaborative; if a speaker cuts off an answer, interruption is possible. The symbol alone does not settle the interpretation.
Look for these in your work
- Reads the convention
- Uses sequence
- Qualifies the reading
A child says 'two foots' after hearing adults say 'two feet'. Compare behaviourist and constructivist interpretations.
Give me a hint
Contrast input and feedback with rule-building from patterns.
Compare my reasoning
- A behaviourist account would examine exposure, imitation and reinforcement.
- A constructivist account may see productive pluralisation of an irregular noun.
- Identify what additional data could distinguish interpretations.
A behaviourist explanation asks what forms the child hears and how adults respond. A constructivist view may treat 'foots' as applying a productive plural pattern. More examples and interaction are needed to compare these accounts.
Look for these in your work
- Represents both approaches
- Connects them to the form
- Identifies evidence needs
A student says a novel child sentence proves Universal Grammar. Improve the claim.
Give me a hint
Separate the observation from theory and consider alternatives.
Compare my reasoning
- State the novel combination as evidence.
- Explain how a nativist account may interpret productive language.
- Mention learning and interaction as alternative or complementary factors.
The novel sentence shows a combination not simply copied in the recorded turn. A nativist account may view productive use as consistent with an innate capacity, but input, analogy and interaction also matter; one sentence cannot prove Universal Grammar.
Look for these in your work
- Describes evidence accurately
- Explains the theory link
- Considers alternatives
Common mistakes
- Treating repetition as proof of long-term learning
- Attributing development only to adult correction
- Ignoring transcription key or turn sequence

A framework for interpreting evidence, not a substitute for it
One observation may fit several explanations and needs context.

Make it stick
How could one utterance be interpreted through two acquisition approaches?
If you needed the solution, close it and solve the problem again from a blank page. A correct answer is stronger when you can explain the reason for each step.
