The National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program2 recently made its third set of awards for projects in three basic tracks: Collections, Services, and Targeted Research. These projects are working with those funded in fiscal years (FY) 2000 and 2001 to build a national digital library of high quality science, technology, engineering, and mathematics (STEM) educational resources for students and teachers at all levels, in both formal and informal settings. By supporting widespread access to a rich, reliable, and authoritative collection of interactive learning and teaching materials and associated services in a digital environment, the National Science Digital Library will encourage and sustain continual improvements in the quality of STEM education for all students, and also serve as a resource for lifelong learning.
Various workshops and planning meetings during the latter half of the 1990s explored and developed the vision and operational framework for the NSDL program [1-6]. Since the program's formal inception in FY2000, interest has grown steadily with proposal submissions increasing from 80 in FY2000, to 101 in FY2001, and to 156 in FY2002. In FY2000 thirteen projects were funded in the Collections track, nine in the Services track, and one in the Targeted Research track. In FY2001 eighteen new Collections projects began, along with thirteen in Services, and three in Targeted Research. Brief descriptions of each FY2000 and FY2001 project appear in  and  respectively; and full abstracts can be found in the Awards section at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) have both provided significant co-funding for fifteen projects in these first two fiscal years, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF.
For the FY2002 funding cycle, the 156 proposals sought approximately $92 million in total funding. Forty-one new awards have been made with a cumulative budget of approximately $25 million. These include twenty-five in the Collections track, ten in the Services track, and six in the Targeted Research track. As in the first two years of the program, sister directorates to the NSF Directorate for Education and Human Resources (EHR) are providing significant co-funding of projects. Participating directorates include GEO and MPS from before, as well as the Directorate for Biological Sciences.
Existing projects from FY2000 and FY2001 address subject domains in the life sciences, geosciences, various areas of engineering, the mathematical sciences, and several cross-disciplinary areas. New projects from FY2002 expand this coverage into areas of chemistry and physics. Other new projects focus on collections of video resources, as well as continued work on collections development and services targeting the pre-K to12 educational enterprise. Indeed, nearly half of all existing and new projects in the program have explicit linkages with the pre-K to12 sector or strong secondary efforts in that area. All projects have interdisciplinary teams of principal investigators from a variety of backgrounds, including expertise in the library and information sciences, computer science, digital library research, disciplinary content, and instructional design.
The past year of the program has also seen the establishment of an information architecture framework for the library resulting from the joint efforts of the NSDL Core Integration project and many of the Collections, Services, and Targeted Research projects. The Core Integration component of NSDL (see <http://cinews.comm.nsdlib.org/>) provides the organizational and technical infrastructure to bind distributed users of the National Science Digital Library to its distributed collections and services. An NSDL community produced white paper, "Pathways to Progress,"  informed much of this work and has also stimulated the emergence of a nascent community governance structure that is jointly establishing guidelines, practices, and policies for participation in the larger NSDL building effort. Complete information on technical and organizational progress, including links to current Standing Committees and community workspaces, may be found at the NSDL Communications Portal, see <http://comm.nsdlib.org>. All workspaces are open to the public, and interested organizations and individuals are encouraged to learn more about NSDL and join in its development.
Following is a list of the new FY2002 awards displaying the official NSF award number, the project title, the grantee institution, and the name of the Principal Investigator (PI). A condensed description of the project is also included. Full abstracts are available from the Awards Section at the NSDL program site <http://www.ehr.nsf.gov/ehr/due/programs/nsdl>. (Grants with shared titles are formal collaborations and are grouped together.) The projects are displayed by track and are listed by award number. In addition, eleven of these projects have explicit relevance to applications to pre-K to12 education (indicated with a * below). Seven others clearly have potential for application to the pre-K to12 arena (indicated with a ** below).
The NSDL program will have another funding cycle in fiscal year 2003 with the next program solicitation expected to be available in January 2003, and an anticipated deadline for proposals in mid-April 2003.
