1. LADL2007 Workshop, 20 Sep 2007, Budapest, HU Polyxeni Arapi Nektarios Moumoutzis Manolis Mylonakis George Stylianakis George Theodorakis {xenia, nektar, manolis, gstylianakis, gtheodorakis}@ced.tuc.gr Laboratory of Distributed Multimedia Information Systems & Applications Department of Electronics & Computer Engineering Technical University of Crete Supporting Personalized Learning Experiences within the LOGOS Cross-Media Learning Platform

2. LADL2007 Workshop, 20 Sep 2007, Budapest, HU  Vision of u-learning: provide effective personalized learning services to support learning anywhere, anytime exploiting alternative delivery channels and related devices  LOGOS Project: Knowledge-on-Demand ubiquitous learning platform to bring the u-learning vision into reality ◦ Layered repositories supporting the gradual development of learning experiences ◦ Authoring Studio of tools for learning content creation ◦ Cross-media delivery of learning experiences by special Learning Management System components and publishing services  Pedagogy-driven personalization beyond “one size fits all” solutions (exploited by learners and courseware authors)

3. LADL2007 Workshop, 20 Sep 2007, Budapest, HU

5.  A widely-accepted Digital Library standard  A flexible, but tightly structured container for all metadata necessary to describe, navigate and maintain a digital object (XML): ◦ Descriptive, ◦ Administrative and ◦ Structural metadata  Each type of metadata is described in a separate section, which is linked to its counterparts by internal identifiers  These metadata (any preferred scheme) may be physically stored within the METS file, or in external files referenced from within the METS document

6. LADL2007 Workshop, 20 Sep 2007, Budapest, HU

8.  Personalization becomes a central issue in modern eLearning environments. ◦ Better exploitation of contents residing at repositories ◦ Efficient services to Learners beyond “one size fits all” solutions  Important pedagogical parameters have to be taken into account: ◦ Different Learners have different learning styles, educational levels, previous knowledge, goals.  Clear separation of pedagogy from content is important. ◦ Current elearning standards and specifications (e.g. SCORM, IMS Learning Design) do not support the selection of appropriate learning objects at run-time.

9. LADL2007 Workshop, 20 Sep 2007, Budapest, HU

10.  Described with metadata encoded in LOM  Extend LOM to provide structured representation of Learning Objectives ◦ Verb (Bloom’s Taxonomy) ◦ Topic (from a domain ontology)

12. LADL2007 Workshop, 20 Sep 2007, Budapest, HU  Model for the construction of abstract training scenarios  Represented in an ontology coded in OWL  Pedagogy is separated and independent from content  Reusability of learning designs or parts of them  Can be used for the construction of personalized learning experiences, where appropriate learning objects according to the learner profile are bound to the training scenario at run-time

13. LADL2007 Workshop, 20 Sep 2007, Budapest, HU

15.  Important elements corresponding to ◦ pedagogical parameters encoded in instructional ontology (filtering of training methods/activities) ◦ learning object metadata elements (filtering of learning objects to be bound to activities)  Could be mapped to existing standards such as: ◦ IMS LIP ◦ IEEE PAPI

16. LADL2007 Workshop, 20 Sep 2007, Budapest, HU

18.  Architecture of the LOGOS cross-media learning platform: ◦ Multiple layers of repositories managing DOs, LOs and COs ◦ Authoring Studio supporting the creation of multi-platform learning content ◦ Mechanisms for delivering learning experiences in several devices  Dynamic creation of pedagogy-sound personalized learning experiences  Testing of the LOGOS platform with real users (educational content authors and learners) and content  Evaluation of the personalization framework in the context of the experimentation phase of LOGOS project
