lar definition
LAR Definition
  • Refers to how educational resources, collections, and their related metadata are aligned to educational goals, curriculum, or professional development needs of users

AND

  • how readily said resources and collections can be embedded in tools and services that educators and students use.
learning application definition
Learning Application Definition
  • Tools and services educators use to accomplish learning tasks

AND

  • that have the ability to embed active & curated content from internal or external sources to support desired learning goals

The goal is to support contextualized learning experiences, allowing users to find and use or deliver just the right digital content

why learning application readiness
Why Learning Application Readiness
  • K-12 and Higher Ed reports emphasize critical missing pieces for educational & digital resources particularly:
    • Lack of coherent integration
    • Lack of platform interoperability
  • NSF has asked NSDL to demonstrate an educational impact
lar guiding principles resources
LAR Guiding Principles: Resources
  • 21st century contexts: advance critical thinking, problem solving, collaboration & recognize the interdisciplinary nature of knowledge
  • Relevant and reliable for STEM education: authored, meet pedagogical needs of educators and interests of learners
  • Accessible: rights, licenses, permissions, & technical requirements clearly stated
  • NSDL policy: Meet Resource Quality Guidelines
lar guiding principles metadata
LAR Guiding Principles: Metadata
  • Complete: title, description, URL, educational level, resource type, audience, language, rights, access rights, creation date, contributors/creators, language, mime type and, if appropriate, educational standards
  • Concise: free of self-promotion; describes purpose and content of resource for comprehension
  • Accurate: the metadata is correct content for the field
lar nsdl scope collections
LAR & NSDL Scope/Collections
  • NSDL has collections that are library appropriate but LAR concepts may not be applicable
    • reference collections
    • dataset collections
  • Collection sustainability/maintenance is important in maintaining LAR
  • Not always easy to determine LAR
using lar resources
Using LAR Resources
  • Done programmatically by learning applications
  • Learning apps using NSDL resources are filtering by:
    • education level
    • resource type
    • subject
    • audience
    • educational standards

For NSDL currently, human-crafted metadata (resource, annotations & usage data) exceeds machine-created metadata in terms of accuracy and quality.

collections assessment process for lar
Collections Assessment Process for LAR
  • Examined individual metadata records to get:
    • Collection size, growth & metadata format
    • Collection use of educational metadata fields
    • Readiness to embed collection in learning app
  • Analyzed educational metadata (fields in next slide)
  • Combined existing NSDL vocabularies & actual metadata values to create benchmark term set for assessment/categorization.
benchmark term set audience
Benchmark Term Set: Audience
  • Administrator
  • Educator
  • General Public
  • Learner
  • Parent/Guardian
  • Professional/ Practitioner
  • Researcher

What do the resources and metadata look like for individual collections?

problem resources metadata gsdl
Problem Resources & Metadata: GSDL

Resources consist of:

Metadata is missing:

Education level

Resource type

Access rights

Rights

Mime type

Creation date

  • Standards documents from the early 2000’s that are out of date or broken and not reachable
  • Reports that have been superseded by more recent reports on education issues
  • Good sounding career information but broken URLs
  • Not really learning resourcesbut career info is valuable if links are updated
good resources metadata needs help chemcases
Good Resources - Metadata Needs Help: ChemCases

Resources consist of:

Metadata is missing:

Has education level but it is in audience

Has resource type (Text). Should include tutorial, instructional & reference material

Audience

Access rights

Creation date

  • Web-based curriculum supplementsfor teaching the 2nd semester of general chemistry
  • Freely available
  • Textual tutorials with explanatory images/diagrams
good metadata resources need help bridge sea grant
Good Metadata – Resources Need Help: Bridge Sea Grant

Resources consist of:

Metadata Has:

Education level

Language

Creator/publisher

Mime type

Resource type

Rights

Title/URL

Description/keywords

Creation date (sometimes)

Missing access rights (has cost instead)

Missing audience

  • Has good resources also cataloged in other collections
  • These include: instructional materials, lesson plans
  • But:
  • Overwhelmed by the number of broken URLs
  • Too many departmental websites and landing pages in research journals

Missing access rights

  • Interactive resources for teaching psychology
  • Peer-reviewed materials
  • Studies, data sets, experiments, demonstrations
  • Teaching aid and instructor support
  • Some materials require class registration.

Resource Questions:

Metadata Questions:

What information is provided by the metadata?

Are the metadata detailed and appropriate for educational use of the resource.

Are metadata fields used correctly?

Can the metadata be used effectively & programmatically by learning applications?

  • What are the resources?
  • What would be the perceived use of the materials?
  • Are the resources learning materials?
  • Are the materials only useful in an educational setting?
metadata assessment of all collections
Metadata Assessment of all Collections
  • All 8 metadata variables for each collections (Sept 2010): http://www.dls.ucar.edu/people/kginger/assessment/reports/
  • Audience, Ed Level and Resource type instantaneous for all collections: http://www.nsdl.org/browse/?subject=All
lar workshop goals
LAR Workshop Goals
  • The NSDL Resource Quality Guidelines exist for resources. What needs to be added if anything?
  • Develop NSDL Metadata Quality Guidelines to flesh out & formalize LAR ideas into criteria developed by and supporting the NSDL community
  • Develop a plan on how to apply the above docs/criteria across the heterogeneity of the NSDL?
  • How to promote LAR as a way of sustaining NSDL’s brand & reputation?
