Aimed at decision makers who will choose whether and how to implement telecommunications efforts in the human services, this final evaluation report describes an intensive demonstration effort, which was conducted by the Alternate Media Center of New York University from July 1979 to September 1980 to show how various telecommunications media, including teleconferencing and microcomputers, might benefit developmentally disabled children and adults. Most of the applications described were focused in rural Vermont, although two involved participants in other states. Discussions of activities in Vermont using audio conferencing, personal computers, and computer conferencing, include a description of Vermont Telecommunications Incorporated, which was created after the completion of the project to promote telecommunications technology for the developmentally disabled and those with other handicapping conditions. A section on national activities describes an electronic mail network and several telecommunications consultation projects. Overall project conclusions and policy recommendations for human service funding agencies conclude the report. Eight appendices include data collection instruments and specific data collection results. (LMM)
