  • Learning as a Service: A Web-Based Learning Framework for Communities of Professionals on the Web 2.0 Ralf Klamma and Marc Spaniol Edinburgh, Scotland, 16 th of August 2007 ICWL 2007 The 6 th International Conference on Web-based Learning
  • Agenda
    • Motivation
      • Web 2.0 and Social Software
      • Communities of Practice
    • LAS (Learning as a Service)
    • Virtual Campfire Framework
      • MECCA (Movie E-learning Combination and Categorization Application)
      • MIST (Media Integrated Story-Telling)
    • Conclusions and Outlook
  • Social Software Second Life 7 WOW 70 MySpace 171 Skype 120 MSN Space 11 LiveJournal 4 Wikipedia 3 Second Life Users (in Millions, by the end of 2006) Social Software
    • Data is the Next Intel Inside -> Unique data
    • Users Add Value -> no restrictions, Inclusive
    • Network Effects by Default -> Collective Intelligence
    • Some Rights Reserved
    • -> Standards, Remix
    • The Perpetual Beta -> Smaller modular Components
    • Cooperate, Don't Control -> Light Web Services, Loose Syndication of data and systems (RSS, Mash-ups)
    • Software Above the Level of a Single Device
    • -> Software mobile and ubiquitous
    • The Long Tail -> Small Communities
    O‘Reilly: What is Web 2.0?, 2005
  • Social Software and Communities: The Long Tail & Fragmentation
    • The Web is a scale free, fragmented network
      • Power Laws (Pareto Distribution etc.)
      • 95 % of users are in the long tail (Communities)
      • Collaboration and Learning is based on trust and passion

  • Communities of practice
    • Community of practice (CoP) as the basic concept for technology enhanced learning
    • Communities of practice are groups of people who share a concern or a passion for something they do and who interact regularly to learn how to do it better
    • Usability & Sociability
    Wenger: Communities of Practice: Learning, Meaning and Identity, 1998 Preece: Online Communities: Designing Usability, Supporting Sociability, 2000
  • TEL Challenges in Social Software
    • Operational support for TEL not satisfying
      • Mono-mediality
      • „ Sticky“ metadata
      • Interoperability only with APIs (Mash-ups)
      • Lacking learning semantics not feasible
    • No reflective support for TEL
      • „ Quality control by feet“
      • Undefined social norms
      • Constitutive impact of media not understood
  • Learning Support for CoP: Reflective Collaborative Learning Collaborative adaptive learning platforms Self-observation tools for Communities Measure, Analyses, Simulate Socio-technical information system Development Jarke, Klamma: Social Software and Reflective Information Systems, 2006 Klamma, Spaniol, Cao: MPEG-7 Compliant Community Hosting, JUKM, Springer 2006 M. Kalz, M. Specht, R. Klamma, M. A. Chatti, R. Koper: Kompetenzentwicklung in Lernnetzwerken für das lebenslange Lernen, 2007
  • LAS Learning As a Service
    • Key Features :
    • - 3-Tier Architecture - Java based Implementation
    • - Connectors - Access Control on Service- and Object-Level
    • - Components (internal) - MPEG-7/21 compliant Multimedia-Services
    • - Services (internal & external) - Extension and Replacement of Services at Runtime
    I-Know 2006 [Spaniol et al.] ICWL 2007 [Spaniol et al.]
  • Virtual Campfire Framework
    • Community Support
      • Java Platform Independence
      • Easy to Maintain and Extend at Runtime
      • Core Services for Community-Administration
      • Fine-grained Access Control
        • Method Level
        • Object Level
        • „ Security-First“-Concept
      • Platform for Community-Hosting
    • Multimedia Support
      • Interoperable (Multimedia) Metadata
      • Cross-Community Support by MPEG-7/21 Compliance
      • Automatic Conversion to/from Dublin Core
      •  Schema-compliant MPEG-7/21 Modifications via XMLBeans
    •  Better Community and Multimedia Support than comparable Application Server such as Tomcat or Zope/Plone
  • MECCA Movie E-learning Combination and Categorization Application
    • - Exploration of Multimedia Artifacts
    • - Illustration of Multimedia Dependencies
    • - Creation of Reference Collections
    • - Comprehensive Discourse Support
    • - Blended Learning
    • - Media Screenings 24/7 via Internet
    Informing Science 2005: [Klamma et al.] ICWL 2005: [Spaniol et al.] Support of Film Study Communities in Research and Teaching by:
  • MIST Media Integrated Story-Telling
    • - Exchange of Multimedia Artifacts
    • - Protection of geo-spatial Data of unauthorized access (e.g. Tomb Raiders)
    • - Recontextualization Multimedia Contents via non-linear Stories
    • - MPEG-7 based semantic Multimedia Annotations
    ICWL 2006: [Spaniol et al.] Knowledge Management Strategies 2007: [Spaniol et al.] Support of an International Community of Researchers in order to Preserve the Afghan Cultural Heritage by:
  • Conclusions
    • Cross m ediality for collaborative learning platforms overcomes
      • Mono mediality of Social Software
      • Linguistic fixation of the Semantic Web
    • Semantic self organization of CoPs supported by
      • Flexible semantic enrichment of complex processes in research, learning and working
      • Research of self observation processes of learning communities of experts
    • Validation of the Concept accomplished by
      • Interdisciplinary research cooperation supporting real world CoPs with diverse learning requirements
      • Implementation of the concept in ongoing courses
  • Outlook
    • Three major fields for innovative learning services
    • Community-specific multimedia semantics enhancement sevices
    • Anytime anywhere learning by reasoning about multiple community contexts
    • Interacting with smart maps by learning mash-ups
