Focus on: - Goal orientated. - Competencies. - Efficency (from A to B in the most efficient). Requieres: - an expert - knowledge representation (VS. Siemens: the knowledge that we have CAN'T be represented) for expl. language -- Problem: it creates a simplification of the knowledge. - learning activities are set up by an expert. -network approach: (???IDF). Conectivism (born 40 years ago Pappert &?). Computational system is NOT set up as a representational system BUT is set up as a NETWORK (like a brain).

Our concept of X is not a symbolic representation but a set up of active connections also in a neuronal level (?) Model of learning NOt based in deduction and inference BUT on ASSOCIATION based on: - concurrency. - proximity. - back propagation (economics: supply and demand market is based on that) - ???Amealing the way form networks/community in society work in THE SAME WAY that they do in a neuronal level and a personal level. Communities ARE networks that work through distributed connections. How should be the network? - DIVERSITY (wide representation of different points of views) Knowledge in a network is: EMERGENT - AUTONOMY : each individual is self-directed. Each individual works as his own guide. - CONNECTEDNESS (or interactivities). Knowledge produced by mechanism of interaction is produced by the nature/properties of the network. The way/organization of connections are formed is essential. - OPENESS (there's no inside/outside the "system"). Connection FLOWS freely. RECOGNITION of patterns (clustter).

    Very interesting discussion about how Google Wave will change everything by DavePollard
Ed Webb

It's Time To Hide The Noise - 5 views

  • the noise is worse than ever. Indeed, it is being magnified every day as more people pile onto Twitter and Facebook and new apps yet to crest like Google Wave. The data stream is growing stronger, but so too is the danger of drowning in all that information.
  • the fact that Seesmic or TweetDeck or any of these apps can display 1,200 Tweets at once is not a feature, it’s a bug
  • if you think Twitter is noisy, wait until you see Google Wave, which doesn’t hide anything at all.  Imagine that Twhirl image below with a million dialog boxes on your screen, except you see as other people type in their messages and add new files and images to the conversation, all at once as it is happening.  It’s enough to make your brain explode.
  • ...2 more annotations...
  • all I need is two columns: the most recent Tweets from everyone I follow (the standard) and the the most interesting tweets I need to pay attention to.  Recent and Interesting.  This second column is the tricky one.  It needs to be automatically generated and personalized to my interests at that moment.

      How do you determine which are the most interesting tweets? What is your criteria?
    • Ed Webb
       
      Aye, there's the rub. This is where those clever algorithms come in that monitor your activity and make suggestions. Like Amazon recommendations. Er, which are always brilliantly spot-on. Or something.
  • search is broken on Twitter.  Unless you know the exact word you are looking for, Tweets with related terms won’t show up.  And there is no way to sort searches by relevance, it is just sorted by chronology.
