    Stephen Wolfram, creator of Mathematica, talks about his quest to make all knowledge computational -- able to be searched, processed and manipulated. His new search engine, Wolfram Alpha, has no lesser goal than to model and explain the physics underlying the universe.

  • This simple change made Google's ad marketplace much more efficient than Overture's. Notice that the algorithm itself is quite simple; it is the addition of the new data that made the difference.
  • Of course, you have to be judicious in your choice of the data to add to your data set.
  • Tony Searl on 17 Jan 11
     
    But the bigger point is, adding more, independent data usually beats out designing ever-better algorithms to analyze an existing data set. I'm often suprised that many people in the business, and even in academia, don't realize this.

    Which brings us to the underlying point of the piece - we are all leaving digital trails behind us, as we make our way around our individual lives. These trails are largely considered individual - even ethereal - yet technology is making these trails more visible and more readable everyday.

    Over the last year, I've produced five data-driven pieces for Wired UK. Four of them have been for the two-page infoporn spread that can be found in every issue. I've looked at the UK's National DNA Database, used mined Twitter data to find people's travel paths, and mapped traffic in some of the world's busiest sea ports.

    The majority of the information that we use in our daily lives is "dumb", or unconnected. The next step is "linked data", or data that talks to each other.

  • The linearity and causality implied within the taxonomy (for instance, the assumption that passing a test at Level 2 will result in improved job performance at Level 3) masks the reality of transferring training into measurable results. Many factors enable — or hinder — the transfer of training to on-the-job behavior change, including support from supervisors, rewards for improved performance, culture of the work unit, issues with procedures and paperwork, and political concerns
  • Robert Brinkerhoff takes a systems view of evaluation of training, believing it should focus on sustained performance rather than attempting to isolate the training effort:
  • learn best from the outliers
  • ...4 more annotations...
  • The method asks evaluators to: Identify individuals or teams that have been most successful in using some new capability or method provided through the training; Document the nature of the success; and Compare to instances of nonsuccess.
  • Stufflebeam
  • training as part of a system
  • a means of formative as well as summative evaluation.

    . I think the interesting thing about Learning Analytics is it's one of those areas we think will be important, but we're not quite sure what it is yet, so there's room to explore

    Can also probably use Diigo to do something similar (e.g., via public sticky notes). Always wonder if that's rude though...you don't give the Moodling person (who might not be using Diigo or the annotation tool) the oppt to respond.

    Goodhart's law states that once a social or economic indicator or other surrogate measure is made a target for the purpose of conducting social or economic policy, then it will lose the information content that would qualify it to play such a role.

  • Remember Goodhart's Law - any statistical instrument used for policy looses all value, or loosely translated the minute a measure becomes a target it ceases to be a measure.

    Is Goodhart's law relevant when thinking about Learning Analytics
