CARD TEMPLATE

CARDS. Java based framework to create models for the products generated with learning tools in order to allow their aggregation and interoperability
• CARDS. Metamodel for other tools– Cardtemplates -> Metamodel– Card -> Models (Tool Results)
Example: COMET. Concept Mapping toolGenerates an image and internal representation XML. CARDS models the final result as a combination of both

Result
Developers design new tools using CARDS metamodel or wrap existing tool models in order to add aggregation or interoperability
Interoperability example. Tools are able to:•Use the outcomes of other tools to configure themselves. •Share outcomes to create aggregated new ones

Pelican learning platform
PELICAN
› An instructional design tool for collaboration› Activity centered› A platform for external tools integration
Activity centered
All instructional processes are based in a collaboration
External tools integration
External tools are integrated in the instructional workflow
Context-adaptation driven
Interactinos of users and groups can rearrange the instructional workflow

Pelican collaborative tool
PELICAN
Social model
Social organization and structure for communities
Collaboration model
Integration model
Intervention model
Organize collaborative experiences and paradigms
Integrate heterogeneous tools and interact with Pelican API
Adaptive context modelized by student performance

LO variety and lifecycleLOs as collaboration support
Collaborative activity iis deifned by the outcome of the students, as LOs.
›LOs as integration support
Information about the collaborative process are LOs too and part of the LO repository
›
›LOs as decission making
Student decissions are shaped as LOs and stored in the repository
Deployment of the adaptation
9E-Madrid -- IEEE EDUCON 2010 Conference M.R. Artacho
Main Goals Automatic extraction and classification of LOs from the web Help content authors in the process of creating and
enriching LOs. Help students finding relevant resources for their learning
tasks Using the WEB as a source to find and extract related
contents to enrich LOs. Aligning retrieved contents to satisfy a learning goal
according to the Revised Bloom’s taxonomy. Involved technologies:
Information Retrieval Formal Concept Analysis (FCA) Ontologies (OWL and RDF) Learning Objects Repository (LOR)
