- Abstract
- In this paper, we discuss a user study done at the formative stage of development of a Math Tools developers' community. The Math Tools digital library, which aims to collect software tools to support K-12 and university mathematics instruction, has two synergistic purposes. One is to support federated search and the other is to create a community of practice in which developers and users can work together. While much research has explored the technical problem of federated search, there has been little investigation into how to grow a creative, working community around a digital library. To this end, we surveyed and interviewed members of the Math Tools community in order to elicit concerns and priorities. These data led to rich descriptions of the teachers, developers, and researchers who comprise this community. Insights from these descriptions were then used to inform the creation of a set of metaphors and design principles that the Math Tools team could use in their continuing design work.

- Abstract
- The National Science Foundation's (NSF) National Science, Technology, Engineering, and Mathematics Education Digital Library (NSDL) program comprises a set of projects engaged in a collective effort to build a national digital library of high quality science, technology, engineering, and mathematics (STEM) educational materials for students and teachers at all levels, in both formal and informal settings. By providing broad access to a rich, reliable, and authoritative collection of interactive learning and teaching resources and associated services in a digital environment, the NSDL will encourage and sustain continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning. Though the program is relatively new, its vision and operational framework have been developed over a number of years through various workshops and planning meetings. The NSDL program held its first formal funding cycle during fiscal year 2000 (FY00), accepting proposals in four tracks: Core Integration System, Collections, Services, and Targeted Research. Twenty-nine awards were made across these tracks in September 2000. Brief descriptions of each FY00 project appeared in an October 2000 D-Lib Magazine article; full abstracts are available from the Awards Section at <http://www.ehr.nsf.gov/ehr/due/programs/nsdl/>. In FY01 the program received one hundred-nine proposals across its four tracks with the number of proposals in the collections, services, and targeted research tracks increasing to one hundred-one from the eighty received in FY00. In September 2001 grants were awarded to support 35 new projects: 1 project in the core integration track, 18 projects in the collections track, 13 in the services track, and 3 in targeted research. Two NSF directorates, the Directorate for Geosciences (GEO) and the Directorate for Mathematical and Physical Sciences (MPS) are both providing significant co-funding on several projects, illustrating the NSDL program's facilitation of the integration of research and education, an important strategic objective of the NSF. Thus far across both fiscal years of the program fifteen projects have enjoyed this joint support. Following is a list of the FY01 awards indicating the official NSF award number (each beginning with DUE), 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 at <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, six of these projects have explicit relevance and application to K-12 education. Six others clearly have potential for application to the K-12 arena. The NSDL program will have another funding cycle in fiscal year 2002 with the next program solicitation expected to be available in January 2002, and an anticipated deadline for proposals in mid-April 2002.
