This final report documents Phase I of a federally funded, naturalistic study of how middle schools can integrate technology into mainstream instruction for mildly handicapped students. Phase I of the study, carried out from October 1986 through September 1989, examined teacher practices that create successful, computer-supported learning experiences for special needs students, and examined the larger school and organizational context that sustains those teacher practices. A total of 23 administrators and 25 teachers from 4 middle schools participated in the 3-year study. Phase II will involve the development and field testing of a school-based intervention to enhance technology use. The report provides an overview of Phases I and II, a description of Phase I research methods and results, a model for a school-based approach to technology integration, and a description of the Phase II technical method. Sixteen study findings are organized into the categories of teacher knowledge and practice, technology resources, teacher development, collaboration and communication, and school-based facilitation. The technology integration model includes the following key elements: a technology integration facilitator, a technology support team, a trainer, teacher dyads, a module-based teacher development program, and school-based facilitation workshops.
