Exciting Megatrends
1.
Third Wave, Semantic, Progammable Web
2.
Knowledge Management
3.
Object-based Learning Environments
4.
Interoperability Standards
New Potential To Renew Pedagogy ?
What are the conditions ?
Internet’s Third Wave

First wave: STATIC TEXT and DATA EXCHANGE
– Primarily static HTML pages: text and data services
– E-mail, FTP, forum (asychronous communication)

Second wave: DYNAMIC MULTIMEDIA
– Dynamic pages, ASP, JSP
– Facilitated transfer of images, sound and video
– Desktop audio/video conference

Third wave: SEMANTIC and PROGRAMMABLE
–
–
–
–
–
–
Integration of applications, API enabled by web services
Ex: Google Alerts, Amazon’s API
Distributed computing, P2P, and mobile networking
Semantic web and knowledege-based technologies
Open source, sharing of objects and applications
New generation of Distributed Learning Environments

Learning Objects: An Open Concept
“A learning object is any entity, digital or non-digital,
that can be used, re-used, or referenced during
technology-supported learning”. (IEEE LTSC 2000)




Includes materials, tools, services, persons, events
Not necessarily digitized, include printed, lab material
Used not only by learners, but also other actors
Includes target and prerequisite competencies or
objectives, activity descriptions, instructional
structure, learning or assistance scenarios, etc.
Information Resources is better
Building LO Repositories
Referencing Learning Objects:
describing properties and types
Searching for Objects
Use cases

Learners (or workers) use LOs in activites and/or
produce LOs that are shared and/or assessed

Trainers (or managers) point interesting LOs to
learners, follow or adapt designs and activities, use
LOs to assist learners (workers), manage repositories

Content Experts build LO repositories and use them
to give advice, presentation or answer questions

Designers build, find, select, store, reference and
assemble LOs (including designs) in environments
(just like a campus professor)
Knowledge Management and LOs





Knowledge Management is
more than « glorified »
document management
It aims at knowledge sharing
and dissemination in an
Information
organization
Increasing competencies
instead of simple information
access
Higher level knowledge
Central role for knowledgebased Instructional

LOM: a step to the Semantic Web






Knowledge Management: a process
where persons publish and use
knowledge objects (resources) on the
Web – learning is central
Knowledge Objects are grouped in
« learning objects repository »
Knowledge Objects are described by
their Metadata: properties and types
of objects
Metadata are a basis for a Semantic
Web description of object
Need to be completed by an
Ontology: relations and axioms
To provide intelligent processing of
content
Value-added Service: Aggregation
Learning Design Aggregation
Environment Aggregation
Apprenant
Environment Construction
Obstacles and Challenges
Technical Challenges

Generic Software
– Separated tools
– Integrated Suite
– Interoperability at the
OS level

DL System
– Separated Tools
– LMS, LCMS
– Web services
interoperability
Pedagogical Challenges





The object paradigm is economical, flexible
and forces pedagogical re-evaluation
Attach more importance to communication
and learning activities than medias,
documents or content
Seperate content object from use scenarios
and learning environments
Reusability must protect ne good quality
learning scenarios
Reuse of learning models can bring more than
just recycling content.
Cultural Obstacles

Lecturing instead of facilitating learning

The library « course »

Lack of pedagogical training of the majority
of teachers

Reproduce the way we have been taucht

IP vs Open Source

Collaboration between content creator and
institutions
