  • 7. The Web as a Platform Jun 5, 2009 e-Learning 2.0
  • 8. Architecture of Participation
    • Users Add Value!
    • Example: The “data base”
    • Yahoo! paid people to build it.
    • Have volunteers build it (e.g. Open Directory Project)
    • Napster had users build it.
    • Key lesson – build value as a side-effect of ordinary use of the application.

  • 9. Web 2.0 Design Patterns
    • In his book, A Pattern Language ,
    • Christopher Alexander prescribes a format for the concise description of the solution to architectural problems. He writes: "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."

  • 11. Some Obvious Effects on e-Learning
    • LMS vendors scurrying to build-in community oriented / social networking / collaboration functions into products
    • Requires increased professional and instructional support for educator adoption and deployment
      • Increased technology gulf between students and educators.
      • Increased pedagogical gap between what “is” done vs. what “could” be done
      • Builds on “student-centered” / constructionist theory particularly in the areas of interactivity, collaboration and engagement.

  • 12. Some Obvious Effects on e-Learning
    • Embraced by the “early adopters” as expected but adoption by the “mid-lers” may be lagging
    • Best practices / effective use unknown or immature
    • Early research shows increased student satisfaction due to increased technology alignment
    • Unimaginable resources – e.g. Archives.org

  • 14. Some Not-So-Obvious Effects on e-Learning
    • 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.
    • Trend longevity? What about tomorrow’s hot web-service? Make or buy (integrate / mashup) decisions.
    • Is all content to all devices all the time and anywhere really a valid goal? Reality check!
