A four-year federally funded project created this resource guide and interactive multimedia computer software program that are designed to increase knowledge and skills about assistive technology for people with disabilities. Project ASTECH targets special educators, related service personnel, and others who need to learn about assistive technology. The specific areas of assistive technology included in the software are computer access, augmentative communication, and environmental control. Individuals can learn about these areas within three main modules. The first module, Exploring the Possibilities, gives an overview of these three areas by discussing the characteristics and categories of devices, by showing representative devices, and by illustrating examples of students using the devices. The second module, Assessment and Application, takes the learner through the assessment process by first giving general information about assessment. Then the module provides specific information about the aspects of motor, sensory, and cognitive performance that may affect technology support decisions. Through guided applications and student applications, learners can apply information they have learned about assessment with specific case studies. The final module, Installation, Programming, and Troubleshooting, gives general information and then applies it to representative devices. The printed 3-ring binder resource guide supplements information presented in the software program. (CR)
