This practicum study was designed to improve the communication and social skills of 43 students (ages 14-22) with developmental disabilities by involving families in at-home treatment activities that reinforced and enhanced in-school and community-based speech/language therapy and by increasing attendance of parents at school meetings and functions. Intervention included development of individualized speech notebooks containing activities, lessons, and creative ideas designed to enhance communication skills across the curriculum, in the home, and in the community. Telephone conferences were held with each family and a talent fair was held to showcase students' communication skills. Results indicated greater attendance by parents at school functions, increased involvement by parents in individualized education program conferences, and increased collaboration of parents and teachers to develop school programs. Appendices include, among others, a family information and involvement survey, sample newsletters, and the talent show program. (Contains 37 references.) (DB)
