Through its Language/Vocabulary research program, the U.S. Department of Education’s Institute of Education Sciences intends to contribute to the improvement of language and vocabulary skills and reading outcomes of students with disabilities. Successful awardees will provide a plan to identify curriculum and instructional practices that are potentially effective for improving language and vocabulary outcomes for children with disabilities; develop interventions for addressing the underlying causes of language and vocabulary difficulties of students with disabilities from kindergarten through middle school; establish the efficacy of existing interventions and approaches for reducing and preventing language and vocabulary difficulties of students with disabilities from kindergarten through middle school; providing evidence on the effectiveness of language or vocabulary development interventions implemented at scale, whether they focus on language and vocabulary outcomes or reading/writing outcomes; or develop and validate language or vocabulary assessment tools for students with disabilities in kindergarten through middle school. Interventions appropriate for development and/or evaluation under this program are those intended to improve language or vocabulary outcomes of children with disabilities or children at high risk for learning disabilities. Interventions may be school-based interventions or home-based interventions that are integrated with school-based interventions and intended to support children’s success in school. The long-term outcome of this program will be an array of tools and strategies (e.g., assessments tools and technologies, instructional approaches) that have been documented to be effective for improving the language and vocabulary skills of children with disabilities from kindergarten through middle school. The Department of Education must receive a letter of intent to apply for this grant by June 6, 2005. The application receipt date for the grant is August 4, 2005.
