Kindergarten Teachers as Models for Children’s Speech

A comparative analysis of kindergarten teachers’ speech with each other and with their students in the classroom demonstrated significant differences on several measures of speech complexity. It was found that adult speech to children used shorter sentences, more simple sentences, and fragments, and fewer compound, complex, compound-complex, and elaborated sentences than adult-to-adult (A-A) speech. On vocabulary measures adult-to-child (A-C) speech showed a lower type-token ratio score and larger percentage of usage of words found in the first thousand most frequent words in the Thorndike-Lorge list. The implications of these results both for language and cognitive development are discussed.
