As a follow-up to a 2007 Edvantia, Inc. report entitled "A Legacy of Leadership and Lessons Learned: Results of the Rural Systemic Initiatives for Improving Mathematics and Science Education," (ED531892) Edvantia, Inc. sought and received support from the National Science Foundation (NSF) to hold a forum in the nation's capital that would profile how practitioners in local school districts leveraged the leadership legacy of the RSIs [Rural Systemic Initiatives] to continue improvements in mathematics and science education. The authors held the forum on July 16, 2008, in the conference room of the House of Representatives Standing Committee on Science and Technology in the Rayburn Building, Washington, DC. This proceeding documents highlights of the forum. Six practitioners on the forum panel shared experiences in their respective RSI and described how improvement capacity built by the RSI was being leveraged. These individuals represented hundreds of their peers who staffed or participated in one of the 28 RSIs. The practitioners worked in or served rural schools in Alaska, Kentucky, Mississippi, Texas, West Virginia, and Wyoming. Representatives of NSF and three other federal agencies--the U.S. Department of Energy, the National Aeronautical and Space Administration, and the U.S. Department of Education--described how their agencies support mathematics and science education in K-12 public schools. The agency representatives shared information about programs and opportunities that school districts and states can use in leveraging the RSI legacy. As a final session, the executive director of the National Council of Teachers of Mathematics reflected on comments of forum presenters and advised participants to take what has been learned in the RSI effort and formulate policy actions that answer questions of education policymakers. Papers include: (1) Setting the Context for Leveraging the Legacy of Leadership in Mathematics and Science Education (Wimberly Royster); (2) Coalfield Rural Systemic Initiative (Jonathan Escue); (3) Sunflower County School District and Delta RSI (Angela Winters); (4) Kodiak Island Borough School District and Alaska RSI (Teresa Schneider); (5) Fort Washakie Charter High School and Wind River RSI (Gene Meier); (6) Resource Collaboratives and the Appalachian Rural Systemic Initiative (Kim Zeidler); and (7) Lyford Consolidated Independent School District and the Texas RSI (Irma Mondragon).
