This catalog is published as one of many mechanisms to stimulate and facilitate continuing communication among the federal, state, intermediate, and local agencies that share responsibility for educational program improvement through nationwide dissemination activities. All the projects cited have undergone close scrutiny by the Joint Dissemination Review Panel within the Educational Division of the Department of Health, Education, and Welfare, and have been approved for national dissemination. A brief description of the program is given along with information on the materials used, services available, target audience, financial requirements, program evaluation, and contact person. The appendix offers several listings of key persons--National Diffusion Network State Facilitators and state coordinators of federally funded programs--who may be able to assist local schools through technical assistance as they search for useful new educational practices. The appendix also cites a handful of projects deemed to be available on only a limited basis. The indexes locate exemplary programs by content, by geographical locale, and by name. (Author/MLF)
