DLESE Mission
“To improve the quality, quantity, and efficiency of teaching and learning about the Earth at all educational levels.” DLESE Strategic Plan
Why a digital library?
A well-articulated community goal to transform geoscience education by combining pedagogy, technology and science
A well-articulated community goal to transform geoscience education by combining pedagogy, technology and science
What is DLESE?
A place to find quality teaching and learning resources about the Earth systemSupport and services for anyone interested in learning about the EarthA community-led effort, funded by NSF The geosciences node of the National Science Digital Library (NSDL)
What does DLESE offer?
Web-based materials (lesson plans, computer and lab activities, data, visualizations, background material, portals)
Resources about the Earth are contributed and described by educators and scientists
Services to help users effectively create and use materials
Search by standards; find teaching tips and reviews; attend workshops and events
Interfaces and tools to allow exploration of Earth data sets
Who is building DLESE?
Individual K-12 and university educators and scientists contribute resourcesPartnerships create thematic collections*Community governance guides library developmentCore services develop library components
Collections, Community, Data, Evaluation, and the DLESE Program Center (DPC)
Discovering ResourcesUsing DLESE
Discovery only for resources related to Earth system science
Resources in DLESE are selected and cataloged by the ESS education community
Resources are described in metadata records which enhance discovery and comprehension of the items. DLESE holds
metadata records, not the actual web pages.
What is Metadata?
Structured descriptive information about a resource that enables discovery
“Data about data” Free text as well as controlled
vocabularies for audience, resource type and others

Collection BuildingDLESE library policies
http://www.dlese.org/documents/policy/index.html
• Scope: what the collection is about• Accession: what’s needed to be a collection• Deaccession: when a collection or resource “breaks”• IP and Privacy: how we treat the collection
DLESE Catalog System – for record creation
OAI software - for collection harvesting
Broad Collection and Reviewed Collection
Broad ReviewedCollection Collection
Relevant to Earth system educationCataloged with a minimum set of information for discoveryWide access to a range of resources
All the criteria of the Broad Collection plus:
• Scientifically accurate
• Importance• Pedagogically
effective• Well-documented• Ease of use• Power to inspire• Robust
Your role this summer
Set the stage for a thematic collection by:Drafting guiding documentsConstructing concept matrix to guide resource selectionExploring the potential resources availableCataloging on-line resources
Initially available as individual resources in DLESE, eventually as part of a discrete collection
Capturing info about off-line resources for future inclusion
Defining a Collection
Scope statement – describes types of resources included in collection
Topically, resource type Goals of collection ; what niche to fill
Short, easy to understandTranslates to a short set of principles or requirements as suitable guides to collecting
Building a Collection
Selection processIn this case, a matrix of topics, subtopics, and resource types will be developed and populated
Review processHow you evaluate the robustness, integrity and validity of the resources, determining which ones to catalog for the collection
How do resources get cataloged?
Web-based cataloging tool (DCS) at www.dlese.org -> public tool for general collectionUnique instances of cataloging tool for formal, thematic collections – managed at project site or hosted by DPCXML files created outside of web tool – XML template or database generated
DLESE Catalog System
Web-based tool to catalog resources with the following:
• URL, title, description, resource type• Grade level, subject (and many more)
Tool can be downloaded for local cataloging use
Can share cataloged information with digital libraries or use at DLESE
Build your own collection
Free-text and controlled vocabularies
Other considerations
Develop preliminary keyword list – possible subsequent specialized vocabularyOff-line resources data gathering
