The Mathematics/Science Partnerships Program resulted from the federal No Child Left Behind legislation enacted in 2001. Supported through funds administered by the NSF and the U.S. Department of Education, it will unite multiple stakeholders in the K-12, higher education, and business communities to ensure that all students have access to, are prepared for, and are encouraged to participate and succeed in, challenging and advanced mathematics and science courses; enhance the quality, quantity and diversity of the K-12 mathematics and science teacher workforce; and develop evidence-based outcomes that contribute to our understanding of how students effectively learn mathematics and science. NSF will award grants to partnership-driven projects to develop innovative ways to improve K-12 student achievement in mathematics and science. Administrators, mathematics and science teachers and guidance counselors in K-12 partner organizations join forces with faculty in mathematics, science, engineering, education faculty and administrators in higher education. The partner organizations commit to implementing coordinated institutional change to encourage the success of the projects. Partners and partner organizations may include a wide variety of business and industry, community organizations, state education agencies, science centers and museums, and private foundations among others. MSP projects are designed to make evidence-based contributions to the learning and teaching knowledge of a larger MSP Learning Network. Ideally, the MSP Learning Network will share successful teaching strategies, provide training and encouragement for mathematics and science teachers and generally improve learning for all students.
