ABOUT
The MacArthur-Bates Communicative Development Inventories (CDIs), and the corresponding Spanish-language Inventarios, provide a systematic way for professionals to use parents as informants regarding their childs language. They enable professionals to tap into parents knowledge about their young childrens communicative development for use in screening and developing a prognosis for children with language delays. It also ensures they are meeting mandates for including parent input in child evaluation procedures.
The goal of the CDIs is to yield reliable information on the course of language development from childrens early signs of comprehension, to their first nonverbal gestural signals, to the expansion of early vocabulary and the beginnings of grammar.
Description
SAVE when you order this item as part of a set.
The CDI: Words and Sentences Forms are for use with children ages 16-30 months. In the first part of each form, parents document the childs production and use of hundreds of words divided into semantic categories. The second part analyzes the early phases of grammar, including the childs understanding of word forms and the complexity of the childs multi-word utterances. Parents identify the words the child has understood or used and provide written examples of the childs three longest sentences.
These forms are part of the MacArthur-Bates Communicative Development Inventories (CDIs). The CDIs and their Spanish adaptation, the Inventarios, are standardized, parent-completed report forms that track young children's language and communication skills. Top language researchers developed the report forms, designing them to focus on current behaviors and salient emergent behaviors that parents can recognize and track.
