E-learning 2.0: you are We-LCoME

  1. 1. E-learning 2.0: you are We-LCoME! Stefano Ferretti Silvia Mirri Ludovico A. Muratori Marco Roccetti Paola Salomoni Department of Computer Science Università di Bologna
  2. 2. Summary <ul><li>Introduction </li></ul><ul><li>E-learning + Web 2.0 = E-learning 2.0 </li></ul><ul><li>Our approach </li></ul><ul><li>Our prototype: </li></ul><ul><ul><li>Design issues </li></ul></ul><ul><ul><li>Architecture </li></ul></ul><ul><ul><li>Use case </li></ul></ul><ul><li>Conclusions </li></ul>
  3. 3. Introduction <ul><li>E-learning: </li></ul><ul><ul><li>Standards (SCORM, IMS LIP, IMS ACCLIP, IMS ACCMD, …) </li></ul></ul><ul><ul><li>Platforms (Moodle, ATutor, Claroline, …) </li></ul></ul><ul><ul><ul><li>Tools ( E-mailing lists, Newsgroups, Whiteboards, Chats, Forums, Online presentations ) </li></ul></ul></ul><ul><ul><li>Actors (teachers, tutors, learners, …) </li></ul></ul>
  4. 4. Introduction <ul><li>Accessible “traditional” e-learning: </li></ul><ul><ul><li>allows distance and flexible educational activities </li></ul></ul><ul><ul><li>decreases the risk of excluding individuals with particular access capabilities </li></ul></ul><ul><ul><li>increases the social inclusion of non-typical learners </li></ul></ul>
  5. 5. Introduction <ul><li>Web 2.0 </li></ul><ul><ul><li>Open participation </li></ul></ul><ul><ul><li>Data decentralization </li></ul></ul><ul><ul><li>Assembly from diverse sources </li></ul></ul><ul><ul><li>Freedom to share and re-use </li></ul></ul><ul><ul><li>Users’ Cooperation and Collaboration </li></ul></ul><ul><ul><li>New Applications and technologies (Blogs, Wikis, Podcasting, Media sharing, …) </li></ul></ul>
  6. 6. E-learning 2.0 <ul><li>E-learning + Web 2.0 = E-learning 2.0 </li></ul><ul><ul><li>new tools and methodologies to work as in an on line community </li></ul></ul><ul><ul><li>Learning objects may be dinamically created, aggregated, classified, syndicated and shared by each e-learning actor </li></ul></ul><ul><ul><li>Learner may become “ prosumer ” (consumer+producer) </li></ul></ul>
  7. 7. E-learning 2.0 <ul><li>If I hear it, I will forget it. If I see it, I will remember it. If I do it, I will understand it. </li></ul><ul><li>~Chinese Proverb </li></ul>And what about if I collaborate?  Collective intelligence
  8. 8. E-learning 2.0: accessibility <ul><li>Dangers for accessibility may be embedded in every innovation </li></ul><ul><li>The complexity and the technologies of collaborative 2.0 tools represents a risk of exclusion for people with disabilities </li></ul><ul><li>The participation of people to the creation and management of contents is a great potential for e-learning accessibility </li></ul>
  9. 9. E-learning 2.0: accessibility <ul><li>Lecturers and learning technologies are charged with accessibility of “traditional” e-learning contents </li></ul><ul><li>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 </li></ul>
  10. 10. Our approach <ul><li>Exploit users’ contribution to cooperatively produce learning objects </li></ul><ul><li>Improve learning objects accessibility by allowing users to add textual annotations and alternative contents </li></ul><ul><li>Collaboration on the Web  Wiki </li></ul><ul><ul><li>Wikitext used to produce HTML pages </li></ul></ul><ul><ul><li>No rich media contents </li></ul></ul>
  11. 11. Our approach <ul><li>No collaborative editing system available for multimedia contents </li></ul><ul><li>A wiki-like system needed </li></ul><ul><ul><li>To add text-based data </li></ul></ul><ul><ul><ul><li>Captions </li></ul></ul></ul><ul><ul><ul><li>Annotations </li></ul></ul></ul><ul><ul><li>To add media data </li></ul></ul><ul><li>Contribution: collaborative system for (multimedia) e-learning contents </li></ul><ul><ul><li>SMIL documents </li></ul></ul>
  12. 12. Our prototype <ul><li>We-LCoME ( Wiki e-Learning Compound Multimedia Environment) </li></ul><ul><ul><li>allows the cooperative creation and sharing of SMIL-based multimedia resources </li></ul></ul><ul><ul><li>makes each user able to create, add, modify, delete each single media composing a didactical resourse and its alternatives </li></ul></ul><ul><ul><li>provides suitable workflows to bind users adding meta information about media contents and their accessibility </li></ul></ul>
  13. 13. Design issues <ul><li>SMIL: allows to describe the spatial and temporal relations inside compound multimedia </li></ul><ul><li>DokuWiki: extended to allow </li></ul><ul><ul><li>accessible collaborative editing </li></ul></ul><ul><ul><li>enhanced wiki-syntax </li></ul></ul><ul><ul><li>accessible SMIL and HTML documents generation </li></ul></ul><ul><li>IMS ACCMD: Accessibility MetaData </li></ul>
  14. 14. Actors and functions phase 2: captioning phase 3: add resources content repository editing system adaptation system Ac2 Ac3 client We-LCoME phase 1: add raw video lecture Ac1

  16. 16. Use case <ul><li>The lecturer adds a video lecture </li></ul><ul><li>Elements are provided by the students support service staff and the teacher </li></ul><ul><li>Learners enjoy the lecture and spontaneously enrich it </li></ul><ul><li>The lecturer corrects and confirms the notes of the previous item of the list </li></ul>

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