The STAR Library Education Network: a hands-on learning program for libraries and their communities, (STAR_Net for short) is led by the National Center for Interactive Learning (NCIL) at the Space Science Institute (PI: Paul Dusenbery). STAR stands for Science-Technology, Activities and Resources. Team members include NCIL staff, the American Library Association (ALA), Lunar and Planetary Institute (LPI), and the National Girls Collaborative Project (NGCP). STAR_Net is developing two comprehensive, informal education programs: Discover Earth and Discover Tech. The project also includes a comprehensive evaluation plan and a research component that explores how public libraries can serve as a STEM learning center in rural, underserved communities. STAR_Net is supported through a grant from the National Science Foundation. The STAR_Net project includes two traveling library exhibits: Discover Earth: A Century of Change and Discover Tech: Engineers Make a World of Difference. The Discover Earth exhibition features interactive, multimedia displays that allow exhibit visitors to interact with digital information in a dynamic way, encouraging new perspectives on our planet. Discover Tech introduces the many extraordinary ways that engineers solve problems to help people and societies around the world. Similar to a science center experience, visitors and families will be able to explore and tinker with their own engineering solutions. A number of STEM activities and resources will be developed by project staff and by other organizations to help librarians and community partners offer a wide variety of programs for their patrons. Besides the traveling exhibits and programs, STAR_Net also includes library staff training (online and in-person) and a Community of Practice (CoP) for librarians (including non-host librarians) to interact and partner with STEM professionals and organizations. NCI's Kate Haley Goldman and staff from Evaluation and Research Associates are conducting the project's evaluation.
