Talking, vocabulary and reading

The language of books has to be taught

The short answer

Does talking with my child and building vocabulary matter for reading?

A U.S. practice guide says everyday talk usually develops by itself, but the more formal language of books and school usually has to be taught. It recommends teaching it, and rates the evidence for that recommendation as minimal. The National Early Literacy Panel found language programs did raise young children's spoken language.

What the research found

  • 4 × Minimal evidence
  • 3 × Reported by a research review
  1. The guide says children who start kindergarten with limited academic language usually trail other children in reading.

    In the source’s own words“Students who enter kindergarten with limited academic language skills typically lag behind their peers in reading.”
  2. The guide says everyday social talk usually develops by itself, but the more formal language of books and school usually has to be taught.

    In the source’s own words“While students typically develop social language skills naturally—those used to communicate informally with family and friends—academic language skills usually require instruction.”
  3. The guide recommends open-ended questions that make children think about what a text is saying.

    In the source’s own words“Use open-ended questions to challenge students to think about the messages in both narrative and informational texts”
  4. The guide recommends teaching the vocabulary of books and school as part of other reading activities.

    In the source’s own words“Teach academic vocabulary in the context of other reading activities.”
  5. The National Early Literacy Panel found spoken language mattered more for later reading when it was measured broadly (grammar, defining words, listening comprehension) than as simple vocabulary.

    In the source’s own words“oral language was found to play a bigger role in later literacy achievement when it was measured using more complex measures that included grammar, the ability to define words, and listening comprehension than when measured using only simple vocabulary knowledge.”
    Reported by a research reviewSource 2, Executive Summary, p. viii
  6. The panel found that programs built to strengthen young children's language did raise their spoken language skills by a large amount.

    In the source’s own words“language-enhancement interventions were successful at increasing children’s oral language skills to a large and statistically significant degree.”
    Reported by a research reviewSource 2, Executive Summary, p. ix
  7. The panel found language programs worked better with younger children.

    In the source’s own words“one important exception was in the area of language interventions, which showed greater effectiveness early on.”
    Reported by a research reviewSource 2, Executive Summary, p. ix

What this means at home

  • Ask open questions about what you read together, not only yes or no questions.
  • Explain new words when they come up in a book, and use them again later.
  • Start early: the panel found language programs worked better with younger children.
  • The free two-minute check points to what your child needs first.

What the research does not tell us

  • The guide rates the evidence for its language recommendation as minimal.
  • In the guide's review, the four studies that measured listening comprehension found no clear effect.
  • The panel placed spoken language among the skills whose link to later reading either weakened once other factors were counted or had not been tested that way.

How we write these pages

  1. We read the source itself, not a news story about it.
  2. Every finding on a page names its source and where in the source it is found, so you can check it.
  3. We say how strong the evidence is, in the words of the people who reviewed it.
  4. We say what the research does not tell us. Most studies are done in schools, and no study can say what one child needs.
  5. If we get something wrong, tell us at hello@sounditoutreading.com and we will correct the page.
