This catalog is intended to make successful programs and practices available so that interested school districts may adapt and install their key elements. All programs were approved by program offices within their funding agencies and often by state education agencies. All were then carefully scrutinized for quality by the Joint Dissemination Review Panel of the Department of Health, Education, and Welfare. All programs demonstrated convincing evidence of effectiveness. Many programs are products of the National Diffusion Network. This annual catalog includes up-to-date information on all programs that were described in previous editions and over 30 additional programs. The appendix offers several listings of state coordinators of federally funded programs who may be able to assist local schools through technical assistance with new educational practices. (Author/LD)
