3. 3 The Shaping of DLESE Workshops (1996) created foundation for expanded NSF Geoscience education activity: Shaping the Future of Undergraduate Earth Science Education: Innovation and Change Using an Earth System Approach Geoscience Education: A Recommended Strategy

4. 4 The Creation of DLESE 1999 Portals to the Future Workshop: (NSF & NASA sponsored) Participants “unanimously voted to move forward…by authorizing the establishment of a steering committee charged to develop a governance plan and organizational structure that will enable construction of the library” Workshop Outcomes: Governance Structure Steering Committee and Subcommittees for Users, Collections, Services, Technology Community Plan

5. 5 DLESE Framework Steering Committee Subcommittees Collections Technology Users Services DLESE Program Center Working Groups Metadata GUI Use Cases Policy Operations DPC supports the DLESE community & its distributed library building efforts Working groups solve specific problems and support the subcommittees in crafting policy Interest groups address and highlight community concerns Outreach Activities Interest Groups K-12 Data Sets Use Cases Community

6. 6 DLESE Vision Provides Rapid, sophisticated access to collections of peer-reviewed teaching and learning resources Interfaces and tools to allow student exploration of Earth data sets Services to help users effectively create and use materials A community center to facilitate sharing and collaboration

7. 7 DLESE Operating Principles Grow from the community Respond to community input/needs Build a federated, distributed effort Measure impact on learning Engage users as contributors

8. 8 Collections Overview DLESE Collections Policy: establishes an Broad and Reviewed Collection May have a Core Collection (centrally held materials of the Reviewed Collection) DLESE collection efforts populate the Broad Collection Each collection effort has a different purpose

9. 9 DLESE Collections Policy DLESE is an information system dedicated to the collection, enhancement, and distribution of materials that facilitate learning about the Earth System and interdisciplinary areas. Favor materials that: Bring the Earth into the learning site Connect the general with the specific, theory with evidence Connect the global with the local

10. 10 DLESE Broad Collection A broad and deep collection of materials that: 1. Follow DLESE’s Collections Policy 2. Conform to DLESE's Intellectual Property Policy (not yet written and includes more than copyright) 3. Have relevance to Earth system education 4. Pass a basic science integrity test Resources in the Broad Collection do not have any further reviews than the filters listed above.

11. 11 DLESE Reviewed Collection Materials that pass the Broad Collection filters and are: Well documented Easy to use Bug-free Motivational for learners Pedagogically effective Scientifically accurate Fosters mastery of significant understandings or skill Classroom tested About 10% of the Broad Collection

12. 12 DLESE Core Collection (Possible) About 10% of the materials from the Reviewed Collection Reproduced electronically at a centralized site like DLESE A repository of classic Earth system resources

13. 13 Collection Efforts (from proposals) 1.DLESE Metadata Working Group (100)* 2.DLESE Collections Subcommittee (5000) 3.NASA Educational Materials 4.DLESE Geo Proposal (1000) 5.K-12 Water in the Earth System Group (100)* 6.ADEPT (Alexandria Digital Earth ProtoType) 7.COMET Multimedia Library ????

15. 15 Purpose of Metadata Group Develop metadata scheme for Earth system science education Address Action Item 2 from Panel 3 Report of Portal to the Future Workshop Define what "well documented" means for each category of materials Metadata: Information about a resource that aids in the discovery of that resource for meeting a user need

16. 16 Key Tasks of Metadata Group 1. Identify resources for the DLESE collection 2. Interpret the metadata framework 3. Develop controlled terminologies 4. Implement community search ideas and assessment techniques into the DLESE metadata framework 5. Catalog resources 6. Develop MECCA (Metadata Entry Tool for Community Centered Assets), a user-friendly cataloging tool 7. Provide cataloging and metadata training to groups involved in the DLESE collection efforts.

17. 17 Metadata Group Collection Laboratory Exercises Conceptual Images Pedagogy Tutorials Case Studies/ Virtual Field Trips Student Portfolios Tools (e.g. Calculators) Scientific Papers Professional Opportunities Problem SetsTheme or Portal Sites CoursesLesson Plans/ Syllabi Images, Animations, Video (observed) Large Data Sets History of Geoscience Assessment Tools/ Rubrics Animations, Applets, Models (simulations) Large Data Set Tools

18. 18 Catalog Process Current: Use editor, XML Spy, to manually catalog resources with some controlled vocabularies Each resource has a metadata creator and editor Future: Java-based catalog tool called MECCA (Metadata Entry for Community Centered Assets) to enter data and create XML records

19. 19 IMS Standard Describes educational learning objects Permits multiple levels of granularity Supports extensibility Uses XML for portable data exchange in both content and structure

20. 20 IMS Defined Categories General: Context-independent features (e.g title) LifeCyle: Features related to the life cycle MetaMetaData: Features of the metadata Technical: Technical features Educational: Educational or pedagogic features Rights: Conditions of use Relation: Relationships to other resources. Annotation: Comments on the educational use Classification: Specific characteristics that aid resource discovery. The characteristics may be features of existing classification schemes (e.g. National Science Education Standards) or may be defined by the user community (e.g. level of review, grade level, and learning styles).

21. 21 Community Desired Metadata Incorporate the National Science Education Standards Indicate level of peer review and classroom testing Reference related resources (e.g.evaluation reports, other exercises or labs) Include instructor comments as annotations

22. 22 Catalog Guidelines Developed initial best practice guide (ongoing) Used IMS category and field definitions to create DLESE category and field definitions Controlled vocabularies are in process (contacting professional societies for subject ones) Create minimal metadata sets for community developed collections (e.g. K-12 group)

23. 23 Sample Metadata Record Remote Sensing Using Satellites Module: Educational information Coverage (temporal and spatial) Related resources Future: use a geo-referenced gazetteer Future: visual geo-spatial referencing for searching

24. 24 Sample Metadata: Remote Sensing

25. 25 Sample Metadata: Remote Sensing Uses controlled terminology of the National Science Education Standards (classification field) Shows level of review (DLESE defined classification field) References evaluation report (relation field) Includes instructor comments as annotations in the metadata record (annotation field)

26. 26 Metadata Group Achievements Developed XML templates for cataloging Extended IMS standard to handle geo-spatial and temporal information better Created a Collection Resource URL Tracker Developed a method for the community to suggest resources (URLs) to the library

27. 27 DLESE Structure & COMET Option 1: Same metadata, database (Cloudscape) and discovery system Option 2: Same metadata and different database and discovery system (SDLIP) Option 3: Different metadata, database and discovery system (use buckets and SDLIP)
