NSDL Entities: Enhancing Educational Interactions

Explore how the NSDL entities facilitate interactions, publication, and reuse of educational resources. Learn about recommendation and classification devices, educational standards, and services/tools for effective learning object management. Greg Janée's insights from the CITI futures kickoff in January 2003 shed light on the vital elements necessary for a robust educational content infrastructure. Join the discussion on the implementation philosophy, community involvement, and the role of specialized interfaces and tools in optimizing the NSDL ecosystem.

  1. CI Requirements A first stab at...

  2. Purposes • NSDL • To allow instructors to publish, discover, reuse, and directly employ learning objects in education. • CI • To facilitiate interactions between providers and consumers of NSDL entities. Greg Janée • CITI futures kickoff • January 6-7, 2003

  3. NSDL entities • Learning objects • Structuring devices • Recommendation devices • Classification devices • Educational standards • Services • Tools Greg Janée • CITI futures kickoff • January 6-7, 2003

  4. NSDL entities • Learning objects • library’s raison d’ être • reusable, ergo: • self-contained • guaranteed availability, persistence • Structuring devices • collections • series, other hierarchies • lectures, courses, curricula Greg Janée • CITI futures kickoff • January 6-7, 2003

  5. NSDL entities • Recommendation devices • annotations, reviews, usage • must be trustworthy • Classification devices • vocabularies, concept maps, etc. • Educational standards • (what is a standard?) • authoritative? Greg Janée • CITI futures kickoff • January 6-7, 2003

  6. RECOMMENDATIONS learning object RIGHTS Learning object facets • DESCRIPTION • standardized • framework • object-specific • CONTEXT • place in larger structures • classifications • versions Greg Janée • CITI futures kickoff • January 6-7, 2003

  7. Services • Service: • CI-provided services • support all NSDL entities • example: navigation of vocabularies; discovery of terms; robust references to terms • may be specifications only • Other services may be registered A network-accessible, programmatic function that operates on NSDL entities. Greg Janée • CITI futures kickoff • January 6-7, 2003

  8. Tools • Tool: • CI-provided (?) and registered A network-accessible human interface that operates on NSDL entities via services. Greg Janée • CITI futures kickoff • January 6-7, 2003

  9. What’s not in CI? • Communities • already handled by MERLOT, etc. • Specialized interfaces • Tools? • yes: needed to exploit services • no: not infrastructure Greg Janée • CITI futures kickoff • January 6-7, 2003

  10. Implementation philosophy • Limit centrality • Enlist federated partners • currently-funded projects • permanently-funded libraries Greg Janée • CITI futures kickoff • January 6-7, 2003
