Research Questions

Progresses of Learning Resource Sharing
Technologies

Reusable
Learning Unit

SCORM

Learning objects

IMS LD

Learning activities

Share of learning
content

Engineering methods and
standards for learning content
sharing

share of education strategies
and learning designs


More aggregation

form single resource to highly aggregated and complex resources


Extending sharing scope

from learning content to learning process and strategies


Technology upgrades

from static learning resources to learning tools & dynamic human wisdom sharing

Future path?


How to share generative information during learning process


How to evolve learning content to adapt to all personalized demands?


How to share social cognition network as well as resources?


How to share interactive learning tools?


How to implement content aggregation based semantic technology?


How to relate learning processes?

Ubiquitous Learning


On demand: Anytime, Anywhere, Mobile…


But more:


Social


Situated


Context awareness


Adaptive

Learning Resource Needed in
Ubiquitous Learning


Anything about everything


Adaptive: learning needs & all kinds of devices


Collective intelligences


Evolutive resources


Situated Knowledge: help learner solve real
similar problems



Deficiencies of Current Learning Technologies


Born in Web1.0 era


Only supports one
-
way information
communication


More focus on formal learning, less on
informal learning



Deficiencies of Current Learning Technologies


Emphasize learning resources and activities
sharing in a close structure


Ignores the continuous updating of learning
resources


Ignores dynamic and generative connection of
learning resources


Ignores building up dynamic relationships
between learners and teachers with learning
resources

The Concept and Architecture of
Leaning Cell

The Concept of ”Learning Cell”


The meaning of “cell”


Component:
learning cells can compose higher

level
learning resources


Origin
: learning cells grow from small to big, from weak
to strong


Nerve cell:
unite to get intelligence


Units that can reunite dynamically


standard

Component


Growing resources


Absorb collective intelligence & wisdom

Origin


Network according to semantic relation


Intelligence, communication ability

Nerve cell

Learning Cell


Generative


Connectivity


Micro

granularity


Evolvable


Cohesive


Intelligent


Social


Open, communicates with other resources


Adaptive to multiple end

(7) Aggregation Model


Different from tree structure of learning objects’
aggregation model, the aggregation model of “learning
cell” is a dynamic network


From resource organization to knowledge organization;
From linear tree

form structure to network structure

Summary


Learning cell……


Extends shareable learning resources in space dimension


Extends shareable learning resources in time dimension


Adopts semantic aggregation mode, integrating content provided by
different learners according to certain knowledge structure, which is a
more practical resource sharing and co
-
editing mode.


Utilizing cloud
-
computing and SOA technologies, making the platform
highly open and extensible; On one hand, learning cells that are
deposited in distributed devices and systems can be shared; on the
other hand, it supports plug
-
in tools, providing multiple content and
functions.
