This guide presents suggestions and materials for providing inservice training about assistive technology for parents and professionals working with infants and toddlers with or at-risk for disabilities. An introduction provides an overview and includes a variety of forms and surveys, a sample inservice agenda, and a list of workshop materials. The inservice program is divided into five strands. For each strand the guide identifies learning objectives, explains principles, suggests some activities, provides related handouts, and suggests additional resources. The strands are about: (1) Baby Tech--basic concepts; (2) family centered programs--the challenges and benefits of parent-professional partnerships in early intervention; (3) communication and language--the nature of communication and building the young child's language skills; (4) play--matching the child's needs and capabilities with toys and play situations; and (5) literacy--developing from birth the young child's four ways of communicating. An additional large section provides instructions and illustrations for making 28 adapted toys. Also included are two sections listing a variety of additional resources. (Contains 70 references.) (DB)
