What is mEducator?
A Best Practice Network (BPN) co-funded by the – eContentplus 2008 programme of the European
Commission, Information Society and Media Directorate-General, Digital Content & Cognitive Systems
Start Date: May 1st , 2009 Duration: 3 years Contract Reference: ECP-2008-EDU-418006
As a BPN, it compares different solutions (2) to draw best practice recommendations

How do people share nowadays
Usually expose individual repositories (instead of allowing distributed searches)
Case of search engines (e.g. Google):– data are restricted to specific kinds of documents
(such as HTML, PDF… i.e. do not harvest metadata as such)
Minimal sharing mechanisms… Minimal interoperability between systems… Peer collaboration ?

mEducator central idea
discover, retrieve, use, rate, re-use and re-purpose educational content irrespective of any Learning Management System use
providers and users of such content may be – expert instructors (academics / health professionals)– students / learners
co-funded by the European Commission eContentplus programme
6
Ultimate goal…
provide mechanisms for content publishing, discovery, & retrieval
analyze policies and mechanisms for content evaluation, rating, renewal and repurposing
elaborate on intellectual property rights for educational material
test the impact of true interoperability, repurposing, enrichment, and embedding of a variety of highly attractive and up-to-date learning resources in each of the partners’ curricula
provide recommendations on how to implement interoperable educational content discovery and retrieval networks

mEducator “content”
refers to any type of educational material with a registered history of creation and evolution
Is linked with – specific educational goals and objectives– learning outcomes – educational contexts/settings
comes recommended with – certain types of teaching methods & strategies– and/or assessment

What is Repurposing?
‘...transforming a learning resource initially created for a specific educational purpose in a specific educational context in order to fit a different new purpose in the same or different educational context’
•Repurposing to different languages •Repurposing to different cultures •Repurposing for different pedagogical approaches •Repurposing for different educational levels •Repurposing for different disciplines or professions •Repurposing to different content types•Repurposing for different technology•Repurposing for people with different abilities•Repurposing to educational content•Changes in the content itself

The competing perspectives (tensions)
End users directly involved in metadata creation….but current metadata standards are difficult to use
– Semantic ambiguity / overlapping– Time consuming process– Not all fields are meaningful (from a sharing perspective)– …where is the learning?
Controlled vocabulary/terminology vs. user vocabulary (taxonomies vs folksonomies)
co-funded by the European Commission eContentplus programme
Proposal of a Tree-based Conceptual Model (Based on
LOM/HealthcareLOM)
Representation of the Tree Model in XML
– XML Schema, XML Example File
Moved towards a Graph-based Conceptual Model (RDF Model)
Proposal of controlled vocabularies for some metadata
elements and linking of them with the RDF Model
Representation of the RDF Model in XML (RDF/XML)
– RDF Schema, RDF Example File

Workshop on eLearning Approaches for the Linked Data Age (Linked Learning 2011, in ESWC2011)

Additional capabilities of the model
static user-edited or automatically generated metadata fields
the emerging, dynamic information clouds that surround a learning resource when users comment on it, tag it etc, i.e. by a combined use of strict taxonomies/controlled vocabularies with folksonomies.
Enrichment: maps profile fields to existing Linked Open Data vocabularies and ontologies

Persuasive technologies & mEducator
need for technologies that are persuasive technologies that are designed to be
persuasive need to be able to execute and present the same content on a variety of platforms
allow for the application of the same principles across different environments
We follow: reduction, tunnelling, tailoring

Content sharing: envisaged solutions
co-funded by the European Commission eContentplus programme
21
mEducator is testing 2 different approaches for sharing
1. mEducator 2.0: loosely coupled LCMSs via mashup technologies (Web2.0)
2. mEducator 3.0: LCMSs linked via (semantic) linked services (Web3.0)

Solution 2 architecture:(1) federated access to eLearning repositories across the Web:integrating existing educational resources from across the Web using Linked Data/Linked Services technologies enabling federated queries for educational resources by end users and 3rd party applications
(2) publishing educational resource metadata as Linked Data: following state of the art Linked Data principles (URIs, RDF, SPARQL, interlinked data with established vocabularies such as SNOMED, MESH, GALEN…)
