The document introduces We-LCoME (Wiki e-Learning Compound Multimedia Environment), a prototype system that combines e-learning and Web 2.0 principles. We-LCoME allows users to collaboratively create and share SMIL-based multimedia learning objects. It provides workflows for users to add metadata about media contents and their accessibility. The system was designed to improve learning object accessibility by enabling annotations and alternative content.

2. Summary Introduction E-learning + Web 2.0 = E-learning 2.0 Our approach Our prototype: Design issues Architecture Use case Conclusions

3. Introduction E-learning: Standards (SCORM, IMS LIP, IMS ACCLIP, IMS ACCMD, …) Platforms (Moodle, ATutor, Claroline, …) Tools ( E-mailing lists, Newsgroups, Whiteboards, Chats, Forums, Online presentations ) Actors (teachers, tutors, learners, …)

4. Introduction Accessible “traditional” e-learning: allows distance and flexible educational activities decreases the risk of excluding individuals with particular access capabilities increases the social inclusion of non-typical learners

5. Introduction Web 2.0 Open participation Data decentralization Assembly from diverse sources Freedom to share and re-use Users’ Cooperation and Collaboration New Applications and technologies (Blogs, Wikis, Podcasting, Media sharing, …)

6. E-learning 2.0 E-learning + Web 2.0 = E-learning 2.0 new tools and methodologies to work as in an on line community Learning objects may be dinamically created, aggregated, classified, syndicated and shared by each e-learning actor Learner may become “ prosumer ” (consumer+producer)

7. E-learning 2.0 If I hear it, I will forget it. If I see it, I will remember it. If I do it, I will understand it. ~Chinese Proverb And what about if I collaborate?  Collective intelligence

8. E-learning 2.0: accessibility Dangers for accessibility may be embedded in every innovation The complexity and the technologies of collaborative 2.0 tools represents a risk of exclusion for people with disabilities The participation of people to the creation and management of contents is a great potential for e-learning accessibility

9. E-learning 2.0: accessibility Lecturers and learning technologies are charged with accessibility of “traditional” e-learning contents New e-learning 2.0 methodologies and tools could be used to make accessible e-learning in practice, by supporting processes that engage all the different actors, from lecturers to students, including people with disabilities, join to work together

10. Our approach Exploit users’ contribution to cooperatively produce learning objects Improve learning objects accessibility by allowing users to add textual annotations and alternative contents Collaboration on the Web  Wiki Wikitext used to produce HTML pages No rich media contents

11. Our approach No collaborative editing system available for multimedia contents A wiki-like system needed To add text-based data Captions Annotations To add media data Contribution: collaborative system for (multimedia) e-learning contents SMIL documents

12. Our prototype We-LCoME ( Wiki e-Learning Compound Multimedia Environment) allows the cooperative creation and sharing of SMIL-based multimedia resources makes each user able to create, add, modify, delete each single media composing a didactical resourse and its alternatives provides suitable workflows to bind users adding meta information about media contents and their accessibility

13. Design issues SMIL: allows to describe the spatial and temporal relations inside compound multimedia DokuWiki: extended to allow accessible collaborative editing enhanced wiki-syntax accessible SMIL and HTML documents generation IMS ACCMD: Accessibility MetaData

25. Conclusions We-LCoME aim is to mashup compound multimedia potentials with the “ collective intelligence ” Final e-learning media contents represent a sort of added value, coming from the iterated process of noting and enriching contents. We-LCoME provides a simple interface (based on the wiki way) to access each media of SMIL based video lectures. A suitable interface is provided to manage the ACCMD metadata about the accessibility of added contents.

26. Future Works Improving the authoring interface spatial dimension of SMIL based video lectures tagging research content (tags and metadata) Adaptation system: Sharing transcoding loads Assessment: Wider group of user Longer period Evaluation of: accessibility of didactical materials availability of didactical materials metadata
