SIGNIFICANT PROGRESS IN CHILD LANGUAGE INTERVENTION - AN 11-YEAR RETROSPECTIVE

This Iiterature review summarizes knowledge gained from 151 articles on child language intervention published between 1978 and 1988. A general theoretical framework for viewing language development is offered as a basis for evaluating progress in the development of language intervention efforts. New developments and issues requiring further investigations are highlighted for five themes that characterize much of the language intervention research in recent years: (1) the development of augmentative and alternative communication systems, (2) the provision of language stimulation to take advantage of observational learning, (3) the teaching of various language functions, (4) the teaching of language as a means of environmental- and self-control, and (5) the study of different types of generalization processes.
