A classroom-based model of language intervention for preschool language-impaired children: Principles and procedures.

It is now generally recognized that a language impairment in preschool children may be predictive of later linguistic, reading, and academic difficulties. Language intervention procedures, derived from theoretically-based principles of language development and implemented in a child's regular classroom environment, may benefit children at risk for persistent language and learning problems. This paper describes the development and application of individualized intervention procedures in a classroom for preschool language-impaired children. The discussion focuses on selected language development principles which helped determine the setting, timing, interactive participants, purpose, and content of the language intervention program. Resulting changes in language comprehension and production are reported based on individual classroom performance as well as a comparison of pre-and posttest scores for a range of comprehension skills.
