3. Fading Education Practices
• Hour-long classes, “seat time”
requirements
• Students grouped by age
• Lecture-based teaching
• Paper textbook as primary
learning resource; No cell
phones in class
• Small, delayed and
disconnected data: some
testing feedback, reports
(midterm, final), attendance,
free lunch eligible
4. Deeply Digital Learning
• Flipped classroom w/online
practice and homework via
adaptive tutors
• More engaging and inspiring
24/7 learning: games, projects,
badges for competencies
• Learners collaborate by ability,
interest
• Digital media/platforms for
open or personalized learning
• Data ecosystems including the
Internet of Learning Things
5. Analytics and Data Mining
• Continuously improving courses, curricula, and apps
• Continuous and stealth
testing
• Personalized, adaptive
learning pathways;
recommended online
learning resources
• Students succeed with the
right challenge, right
encouragement, and right
engagement
• Interactive data
visualization systems (aka
“dashboard”) for learners,
teachers, leaders
6. Stovepiped repositories hold data and
share through pipes like OAI-PMH
Metadata grows stale as people refuse to
update or even add at the outset
Data exhaust is wasted: it’s not powering
anything
Learning resources languish “on the shelf”
Data is locked in and locked down
7. Stovepiped repositories hold data
and share via pipes...
Vs.
Data is shared in the open for
aggregation, amplification,
analysis…
8. Metadata grows stale as people
refuse to update or even add at the
outset (“We can’t plan on good
metadata.”)
Vs.
Enrich the data pool with social
usage data (attention metadata,
paradata) to add nuance to
metadata
9. Data exhaust is wasted−it’s not
powering anything
Vs.
Data exhaust is collected to power
the social life of learning
resources
11. Data is locked in and locked down
Vs.
Democratization/Liberation of
data
12. Data is shared in the open for
aggregation, amplification, analysis…
Learning Registry is a distributed
system that permits sharing of metadata
about learning resources
…developed through an open community
process that engages learning resource
creators, publishers, curators, and
consumers.
13. Learning Registry is a store-
and-forward data exchange
network—not a destination
website, search engine, or
repository—upon which diverse
user services can be built.
Enrich learning resource data with
paradata to add nuance to metadata…

19. Many learning resource systems
can be connected into the Learning
Registry network through publish
and consume APIs
Learning Object Repositories,
Teacher Portals, Search tools,
Learning Management Systems,
and Instructional Improvement
Systems.

20. Currently the Learning Registry
mainly contains metadata, published
+ from a number of collaborators, about
resource classification and usage data.
SHOW JIMS MAPPING HERE
21. Built on CouchDB document distribution
system: easy to set up new nodes and
replicate
Metadata agnostic: uses JSON key-value
pairs to encapsulate metadata in any
schema
Social usage data modeled on NSDL
Com_para and activity streams
Uses URL to identify resources; submitter
identity verified by digital signature
22. Paradata Schema
-- actor (required, except for assertions): the person or group who
does some-thing; a string or a compound object (as shown below) that
describes characteristics of the actor
object-type: the actor value
description: information about the actor
-- verb (required): the action that is taken; it can be a simple string. If
it is a compound object, then verb contains:
action: the verb value
measure: the occurrences of the verb (whether counts,
averages, ratings, or other things).
date (optional): start time / stop time when the action occurs.
context (optional): place where the action takes place
-- object (optional): the thing being acted upon. The important part of
an object is the URL (or URI) where you can find out about the object
(or get the object, or ideally both).
-- related (optional): describes a relationship between the object
(above) and other objects listed within
-- content (optional): a human-readable string description of what the
paradata item expresses

25. Recommendations by clustering users or by
building a social network graph and then
recommending resources among a cluster or
network.
Feedback to developers about the utility of their
resources, about who adapts them and how, and
could eventually cause “widespread sharing” of
learning resources to learners at the appropriate
time.

28. What’s Next?
Work on identity, creating the “network effect,”
digital signing for spam control, fear of loss of
competitive advantage from data sharing
Gathering performance statistics
LRMI validation (tip the preference to LRMI)
Accessibility metadata

Notes de l'éditeur
Thanks for the opportunity to speak about the Learning Registry. It’s always good to hear how new audiences react to it. I’d like to take this opportunity to acknowledge the organizations who provided funding and staff support for the Learning Registry, the US Department of Education and the US Department of Defense. I’d also like to give a special shout out to several organizations who were early testers and experimenters with the LR, National Science Digital Library, a California-based company that specializes in teacher portals, called Navigation North, and the UK higher ed organization JISC which ran the JLeRN Experiment to create and test an LR node at Mimas in 2011 and 2012.
I’d like to talk about what we think is missing from the dialogue about learning resources. But first I’d like to remind us about the changing landscape of learning, first by looking back in time…
We’re seeing some signs that these practices are becoming less common in K-12 classrooms: judging students learning opportunities by how much they are in formal learning situations hearing lectures, grouping them by age, using paper as the medium for knowledge delivery and exploration; and for all practical purposes, open-loop feedback systems.
What’s the evolution of these fading practices? No lectures, more continuous learning experiences, collaborative and personalized learning, and data, data, data.
Many see the enablers of these changes being the ability to take advantage of the data intelligently. Closed feedback systems enable learning objects to be improved, let instruments collect assessment data surreptitiously, enable recommendations and adaptations; support engagement, grit, tenacity, and persistence; and keep the human in the loop to create “data curious” consumers who use patterns in data as opportunities for reflection and discussion.
That said, to RECOMMEND learning resources, we need to LOCATE them. What’s holding us up?
