    3. 3. 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 <ul><li>Data is the Next Intel Inside -> Unique data </li></ul><ul><li>Users Add Value -> no restrictions, Inclusive </li></ul><ul><li>Network Effects by Default -> Collective Intelligence </li></ul><ul><li>Some Rights Reserved </li></ul><ul><li>-> Standards, Remix </li></ul><ul><li>The Perpetual Beta -> Smaller modular Components </li></ul><ul><li>Cooperate, Don't Control -> Light Web Services, Loose Syndication of data and systems (RSS, Mash-ups) </li></ul><ul><li>Software Above the Level of a Single Device </li></ul><ul><li>-> Software mobile and ubiquitous </li></ul><ul><li>The Long Tail -> Small Communities </li></ul>O‘Reilly: What is Web 2.0?, 2005
    4. 4. Social Software and Communities: The Long Tail & Fragmentation <ul><li>The Web is a scale free, fragmented network </li></ul><ul><ul><li>Power Laws (Pareto Distribution etc.) </li></ul></ul><ul><ul><li>95 % of users are in the long tail (Communities) </li></ul></ul><ul><ul><li>Collaboration and Learning is based on trust and passion </li></ul></ul>Islands Tendrils IN Continent Central Core OUT Continent Tubes Barabasi: Linked – The New Science of Networks, 2002 Anderson: The Long Tail: Why the Future of Business is Selling Less of More, 2006
    5. 5. Communities of practice <ul><li>Community of practice (CoP) as the basic concept for technology enhanced learning </li></ul><ul><li>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 </li></ul><ul><li>Usability & Sociability </li></ul>Wenger: Communities of Practice: Learning, Meaning and Identity, 1998 Preece: Online Communities: Designing Usability, Supporting Sociability, 2000
    6. 6. TEL Challenges in Social Software <ul><li>Operational support for TEL not satisfying </li></ul><ul><ul><li>Mono-mediality </li></ul></ul><ul><ul><li>„ Sticky“ metadata </li></ul></ul><ul><ul><li>Interoperability only with APIs (Mash-ups) </li></ul></ul><ul><ul><li>Lacking learning semantics not feasible </li></ul></ul><ul><li>No reflective support for TEL </li></ul><ul><ul><li>„ Quality control by feet“ </li></ul></ul><ul><ul><li>Undefined social norms </li></ul></ul><ul><ul><li>Constitutive impact of media not understood </li></ul></ul>
