The Children's Language Institute Preschool Project developed a successful classroom-home language intervention program for mildly to mildly-to-moderately language-impaired preschool children. An overview of the project, its rationale, and its results in terms of positive change in families and children are described. This volume is designed to assist others in replicating the project in public settings, and contains the following chapters: "The Pragmatics Revolution: The Theoretical Basis for Moving Therapy from the Clinic Cubicle to the Classroom," (Judith Bergman); "Selecting the Population," (Bergman); "Social and Emotional Development of the Preschool Child," (Barbara Zellan); "Interacting with Preschool Children in Groups: Guidelines for Understanding and Managing Behaviors," (Mary Ann Gianni); "Preparing the Preschool Classroom: The Use of Space, Furniture and the Arrangement of Learning Materials," (Gianni); "Choreographing Language Therapy in the Preschool Classroom," (Bergman); "Guidelines for Implementing the Parent Home Visit and Support Programs," (Zellan and Bergman); and "Results of the Project: Positive Change in Families and Children," (Quin, Bergman, Zellan). Approximately 200 sample lesson plans are provided to illustrate specific examples of the integration of language remediation targets into preschool activities. The lesson plans focus on structured language lessons, arts and crafts, circle time activities, cooking, music, science, story time, theme areas, and theme days and weeks. (JDD)
