Many school staff and their client communities are concerned about student achievement, skills, and attitudes related to science. To respond to these concerns, staff need to determine how they can improve their science programs by modifying the content and skills emphasized in the curriculum, changing and supplementing instructional materials, changing instructional approaches, and changing the use of technology. This digest discusses publications and sources of information on exemplary programs from several states and national organizations. Highlighted are efforts of the National Diffusion Network (NDN), the National Science Foundation (NSF), the Educational Products Information Exchange (EPIE), Regional Educational Laboratories, The Educational Resources Information Center (ERIC), the COSMOS Corporation, the Department of Education, and the National Science Teachers Association (NSTA). A list of information sources and 18 references are included. (CW)
