This report presents brief descriptions of exemplary programs validated by the National Diffusion Network (NDN) and approved for national dissemination by the Joint Dissemination Review Panel, which focus specifically on the effective use of technology in education. As exemplary projects called Developer Demonstrators, 12 of the programs described receive Federal funds to provide training, materials, and assistance to groups that wish to set up similar programs. Four of these Developer Demonstrators receive supplemental funding to provide expanded services as NDN Technology Lighthouse Projects. Seven other programs described in the report currently receive no NDN funds for diffusion activities, but may offer services through cost/service agreements with potential adopters. All of the programs are concerned with computer applications in educational administration, management of instruction, and occupational training; computer literacy; computer- or technology-assisted-instruction in basic skills; technology utilization in education for the handicapped; and/or mass media technology. Information provided for each lighthouse project includes brief reports on facilities, equipment, and resources; services; staffing; special features; procedures for visitation; and a contact person. Descriptions of the other programs include scope, target audience, evidence of effectiveness, implementation requirements, financial resources, services, and a contact person. A directory of NDN State Facilitators is provided. (MJL)
