Designed for early childhood educators working with children who have a wide variety of disabilities, this manual discusses the ways in which assistive technology can facilitate the child's active participation in developmentally appropriate activities and offers ideas for incorporating devices and strategies into daily school and home routines. Chapters 1-5 provide an opportunity to explore and review the foundations of assistive technology including relevance to real life tasks, legislative mandates which have created the framework for accessible technology, services to people with disabilities, and the importance of a team-based technology selection and service delivery process. Specific assistive technologies for positioning, access, communication, play, and computer use that are available to enhance a child's independence and skill development are introduced. Chapters 6, 7, and 8 focus on implementation issues: curricular issues that foster and support a "big picture" approach to assistive technology use in educational settings; the relationship between the Individualized Education Program process, technology implementation, and functional outcomes; and funding options. The final section offers guidelines and suggestions for training personnel to become effective assistive technology trainers. Appendices include instructions for creating many of the low cost and simple technology items mentioned throughout the manual. (Contains 67 references.) (CR)
