This report describes the development and field testing of a federally funded model designed to integrate technology into the high school curriculum of students with disabilities. In this second phase of a 5-year study, six high schools located in four school districts were used to evaluate the model. The model is based on the premise that technology integration is a district- and school-wide process of organizational innovation, which requires a coordinated program among administrators, trainers, technical support staff, teachers, and students. A manual describing the model and providing materials and recommendations in each of the four interconnected domains (administrative, human resources, material resources, and instructional applications), was developed and distributed to participating sites. Results indicated the model of technology integration was a useful conceptual tool for schools undertaking or involved in the technology integration process and provided a framework for decision making and policy formulation. As a result of the evaluation, however, the manual was reorganized to concentrate on practical concepts useful to those planning and implementing technology use in the schools. The report describes the different domains of the model, provides analytical summaries of the field sites, and discusses the results of the technology survey and other substudies. (CR)
