One of nine competency-based training modules for personnel preparation in early childhood special education, this guide focuses on assistive technology and technological interventions in preschool programs. All modules are adaptable for use with a general audience, direct service personnel, or administrators and are based on the following principles of the Ohio Department of Education's Division of Early Childhood Education: developmentally appropriate practice; integration of children with disabilities with typically developing peers; collaborative relationships with families; attention to individual needs; and provision for and valuing of diversity among young children and their families. modules are intended to be used in whole or in part, in groups or for self-instruction. Each module comprises goals; competencies (knowledge, skill, and values and attitudes); and objectives, with a matrix for each objective identifying enabling activities, resources, and leader notes. Relevant handouts, forms, and readings are provided for each objective. This module focuses on six goals: (1) gaining an overview of assistive technology and its curricular role; (2) familiarity with switch applications to increase the independent control and participation of young children; (3) understanding the basic use of computers and peripherals; (4) understanding of how computers and peripherals can be integrated into the curriculum; (5) gaining an overview of augmentative and alternative communication systems; and (6) obtaining practical information regarding funding for assistive technology devices and services.
