## National Science Digital Library (NSDL)

NSDL is the National Science Foundation's online library of resources and collections for science, technology, engineering, and mathematics education and research.The National Science Digital Library is a national network dedicated to advancing STEM teaching and learning for all learners and both formal and informal settings, and the locus of activity for the National Science Foundation's National STEM Distributed Learning program. NSDL receives the majority of its funding through the generous support of NSF's Division of Undergraduate Education(DUE), Directorate for Education and Human Resources (EHR).

NSDL advances STEM teaching and learning by providing:

- High quality, interactive resources that help our nation's educators bring cutting-edge, real-world science into their classrooms and stimulate excitement for science in today's digital learners
- Web-based applications that help teachers and learners to optimize their experiences with digital content
- Professional learning opportunities for college faculty, K12 teachers, and other science educators
- Software tools and services to help school districts, museums, educational non-profits and otehr digital learning enterprises to organize, manage, and disseminate digital educational content
- Research-based findings and best practices on teaching and learning with digital content
- Partnerships with STEM stakeholder groups, organizations, and coalitions that promote the dissemination of STEM educational technology use and digital content expertis
