"High-quality input means that adult language in the classroom is characterized by diverse content, form, and use. Content, form, and use are the three
interrelated elements of language that form the complex whole of oral language.
Content consists of the words that are used and the concepts that are expressed; this term is more or less synonymous with vocabulary, or semantics. Children experience many different word types, including adjectives, nouns, verbs, prepositions, and adverbs. Children are exposed to the ways that important societal concepts are expressed, such as kinship (brother, uncle, aunt), time (tomorrow, yesterday), and shelter (house, apartment). Children are exposed to gradations of precision in using vocabulary (old, stale, musty), learn the multiple meanings of words (run), learn to organize concepts (farmer, nurse, pharmacist), and learn how to play with words (a grasshopper man is a man who collects grasshoppers). Children are exposed to diverse ways to express similar things (that towel, that white towel, the towel
he has).
Form refers to the way that word structure and sentence structure are organized grammatically and phonologically. Children experience many different
grammatical constructions, including elaborated noun phrases (the old dark house), various verb constructions
(walks, is walking, will walk, walked), and prepositional phrases (under the table). Children hear sentences that are simple, complex, and compound; and they are exposed to diverse ways to link ideas syntactically (e.g., If you want a sticker, you need to come and get one). Children experience question types of many different constructions, including auxiliary inverted (Is he going?), tag (He is going, isn't he?), and the who, what, when, why, where forms of questions.
Use refers to the ways that language is used in functional contexts to achieve social purposes. Children are exposed to the many ways that language is used for social and functional purposes. Children are exposed to diverse speech acts (label, repeat, answer, request, greet, protest) and learn conversational moves (initiating a topic, maintaining a topic, closing a topic). They listen to and produce stories that are organized temporally and causally, and they are exposed to strategies for solving communication breakdowns.
They are encouraged to initiate with their peers, to take turns, and to negotiate for objects. They learn how to
talk to different people (friends, teachers, librarians) in different settings (schools, stores, homes).
Children's content, form, and use achievements directly
reflect their experiences with language in the world around them (Hart & Risley, 1995). Thus, exposing children to language that is diverse in these three areas
is an important feature of the language."
