Results are presented of a federally funded project that identified new communication aids, software, and assistive technologies that can be used in special education with students who are limited English proficient. The research was conducted in learning centers that use the comprehensive Competencies Program (CCP) English-as-a-Second-Language (ESL) curricula and materials. The CCP ESL Program served as the core curriculum for the project sites, which included special education classes, a middle school, a high school, and an adult education and employment program. Report contents cover: project activities; program operations at four sites in Texas, Massachusetts, and Virginia; program evaluation results; case studies of 19 student participants; a plan for disseminating and marketing the project's outputs; suggestions to improve the CCP ESL curricula and materials; and suggestions for future research and development. For each of the program sites, information is included on hardware configurations, classroom staffing, software usage, and instructional patterns. Information is also provided on 13 computer-based instructional tools, including their strengths and weaknesses for meeting the needs of non-English-speaking or limited-English-speaking adults with handicapping conditions. Appendices include: a literature review, the interview/observation log, information on learning problems of project participants, and other project results. (Contains 55 references.) (SW)
