“You just cannot compete with the scale of the Rockies. So we tried to make a building that was without the conventional scale you get from recognizable floor heights – as in those monolithic structures that still survive from the cliff-dwelling Indians.” – I.M. Pei

Overview

NSDL and DLESE Digital Library (DL) components of

cyberinfrastructure Knowledge representation in DLs Example applications

Digital Libraries: Overview

Discovery of educational resources, data sources, tools, visualizations, etc.

Resource and information sharing and reuse

Support learning and knowledge formation

NSDL 1,000,000+ discrete

items 120+ projects in 74

institutions Encourage and sustain

continual improvements in the quality of STEM education for all students, and serve as a resource for lifelong learning

DLESE 20,000+ discrete

items 20+ collections from

~15 institutions To provide support

and leadership to the Earth System community in addressing the national reform agenda for science education, scientific literacy

NSDL OverviewFunding Agency: National Science Foundation

Education and Human Resources Directorate Initiated by NSF in 2000 as R&D project, now part of

NSF’s educational cyberinfrastructure

Scope: Education at all levels (K12, Higher Ed, Lifelong Learning, Research)

Science, Technology, Engineering, and Mathematics

Structure: Distributed holdings and services, provided and maintained by many organizations

All joined by a “Core Integration” team, comprisingUniversity Corporation for Atmospheric Research – Kaye HoweCornell University – Dean KrafftColumbia University – Kate Wittenberg

All joined by the DLESE Program Center at the University Corporation for Atmospheric Research

DLESE Collections

Collections of metadata from ~15 institutions

UCAR, NASA, NOAA, GLOBE, National Academy Press, COSEE, Alexandria Digital Library, others

DL Cyberinfrastructure Distributed Library Archives

Articles, dissertations, education resources Distributed Services

Web services and APIs Content and metadata interoperability protocols Built on archives, or as compounding of services

Distributed Providers Digital libraries, data holders, publishers,

professional organizations, institutional archives & libraries

Challenge: integrating distributed technical and social systems to support learning and knowledge construction

Metadata and content repositories (aggregations)

Examples: NSDL, DLESE

Approach: Layered Knowledge Services(Sumner et.al., 2004) Level 1: Characterization services

Item level/collection level metadata, data registration

Level 2: Filtering services Search and browse, data slice, partitioning

Level 3: Elaboration services Annotations, reviewing, linking through concepts,

augmenting with vocabularies Help users, and programs, to make connections

Level 4: Viewing and Interacting Services Visualization Tools, Cognitive Tools, Content

Management Systems, etc.

Characterization Services Cataloging tools Metadata and content standards for collecting and describing

educational materials Filtering Services

Search Services and APIs: REST and JavaScript services for discovering, displaying and using content

Elaboration Services Concept Space Interchange Protocol: a concept space web

service Viewing and Interacting Services

Library search and portal pages: www.dlese.org, www.nsdl.org Strand Map Service: Visualization of concept maps NSDL Expert Voices: Interactive knowledge sharing blog space DLESE Teaching Boxes: Classroom-ready instructional units

created by teachers, scientists and designers
