    8. 8. Architecture of Participation <ul><li>Users Add Value! </li></ul><ul><li>Example: The “data base” </li></ul><ul><li>Yahoo! paid people to build it. </li></ul><ul><li>Have volunteers build it (e.g. Open Directory Project) </li></ul><ul><li>Napster had users build it. </li></ul><ul><li>Key lesson – build value as a side-effect of ordinary use of the application. </li></ul>Jun 5, 2009 e-Learning 2.0
    9. 9. Web 2.0 Design Patterns <ul><li>In his book, A Pattern Language , </li></ul><ul><li>Christopher Alexander prescribes a format for the concise description of the solution to architectural problems. He writes: &quot;Each pattern describes a problem that occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice.&quot; </li></ul>Jun 5, 2009 e-Learning 2.0

    11. 11. Some Obvious Effects on e-Learning <ul><li>LMS vendors scurrying to build-in community oriented / social networking / collaboration functions into products </li></ul><ul><li>Requires increased professional and instructional support for educator adoption and deployment </li></ul><ul><ul><li>Increased technology gulf between students and educators. </li></ul></ul><ul><ul><li>Increased pedagogical gap between what “is” done vs. what “could” be done </li></ul></ul><ul><ul><li>Builds on “student-centered” / constructionist theory particularly in the areas of interactivity, collaboration and engagement. </li></ul></ul>Jun 5, 2009 e-Learning 2.0
    12. 12. Some Obvious Effects on e-Learning <ul><li>Embraced by the “early adopters” as expected but adoption by the “mid-lers” may be lagging </li></ul><ul><li>Best practices / effective use unknown or immature </li></ul><ul><li>Early research shows increased student satisfaction due to increased technology alignment </li></ul><ul><li>Unimaginable resources – e.g. Archives.org </li></ul>Jun 5, 2009 e-Learning 2.0

    14. 14. Some Not-So-Obvious Effects on e-Learning <ul><li>LMS vendors are missing opportunities to integrate to third party web services which might increase speed to market and improve product agility. e.g. Google maps. </li></ul><ul><li>Trend longevity? What about tomorrow’s hot web-service? Make or buy (integrate / mashup) decisions. </li></ul><ul><li>Is all content to all devices all the time and anywhere really a valid goal? Reality check! </li></ul>Jun 5, 2009 e-Learning 2.0
