OER Slow adoption – Why ?

Conservation attitude – Fear of critics.Sharing is not encouraged or organized.Closed, rigid institutional processes for OER.Multiplicity of IP owners.Multiplicity of norms and application profiles.Heavy indexing processes.Unfriendly tools and inadequate technology

Communication between norms, standards and application profiles

The RDF Model as a basis for OER

URIs are unique identifiers for data (resources) and vocabulary terms (concepts and properties) used at the global scale of the Web to form relations (RDF triples).

Each RDF triple in the can be a starting point for the exploration of the global Web of linked data.

The RDF model enables tracing links between data from different sources. Information in these sources can be combined by joining them in a single RDF graph.

Adding to an RDF graph schema languages such as RDF-S or OWL adds powerful inference capabilities.

SPARQL end points can be processed by software agents

2. Quality for reuse process (Q4R), methodological guides to support repository implementations.

3. COMÈTE – a mature 2nd generation OER manager for the Web of data and ISO-MLR.

Plan



From OERs to MOOCs

MOOCs must be OERs aggregates …so that MOOCs are really open.

MOOCs are large OERs (modules) grouping all kinds of resources: actors, documents, tools, activivities, scenarios

MOOCs require OER management by learners and facilitators.

MOOC platforms and portals should provide OER management for referencing, search, adaptation, recontextualisation, integration

Research challenge:Massive vs Personalization

Sustain designers for the personalization of MOOC scenariosIntegrate various forms of LD adaptation

(ITS, Recommenders, …)Provide options and resource alternatives,

“liberty to learn” (C. Rogers)Support self-management of learning –>

resource management

Personalized learning puts in priority the needs, interests and goals of learners, taking in account their learning styles, competencies, culture, etc.

Quality <= Personalized <= Open

Adapt xMOOC scenarios

Add a classifying module (competency self assessment, peer assessment, automatic question-answering)

Provide options suited for a sub-group

Integrate recommenders/advisors on critical activities

Define rules that consult the learner’s competency profile (or e-portfolio)

Open participative environments

Environments design that continue after the initial delivery of a course.

Environments that combine OERs specific to a course with resources in a learner’s personal environments.

Resources created or modified by learners using social web tools, promoting emergent learning.

Sharing design partly between facilitators and learners.

We have…

Presented a solution to one of the main problems in Open Educational Resources repositories: multiplicity of norms, standards and application profiles

Built COMETE a first Linked data OER repository manager, largely complying to the new ISO-MLR standard.

Proposed Its use for referencing MOOC and MOOC components using RDF triples would become an asset as the number in massive online courses is growing rapidly in most countries.
