Reflections on the Knowledge Society » MOOCs - from micro to macro - 0 views

  •  
    The first impressions I have of a venture like this are positive but not without hesitation. I won't conceal it from you that it is less the topic of "learning analytics" that's of interest to me (although I am ready to learn something about this too), but the course itself. This is also where my hesitation lies, but we shall talk more about this later in the course.

  • 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

dataists » Blog Archive » A Taxonomy of Data Science - 0 views

  •  
    We thought it would be useful to propose one possible taxonomy - we call it the Snice* taxonomy - of what a data scientist does, in roughly chronological order: Obtain, Scrub, Explore, Model, and iNterpret (or, if you like, OSEMN, which rhymes with possum).

elearnspace › What are Learning Analytics? - 0 views

  •  
    Learning analytics is the use of intelligent data, learner-produced data, and analysis models to discover information and social connections, and to predict and advise on learning. EDUCAUSE's Next Generation learning initiative offers a slightly different definition "the use of data and models to predict student progress and performance, and the ability to act on that information". Their definition is cleaner than the one I offer, but, as I'll detail below, is intended to work within the existing educational system, rather than to modify it. I'm interested in how learning analytics can restructure the process of teaching, learning, and administration.

Week 3 LAK11 - Slackers report » Dave's Educational Blog - 0 views

  •  
    Ah… the semantic web. The saviour of the internet, and the evil empire enforcing its evil standardization upon my freedom. I've always been a little suspicious of this particular topic. Not that I'm opposed to any kind of stardardization, railroads and the lack of standardizations with bank cards at grocery stores come to mind (grrr…) But the semantic web and how data is 'linked' is pretty important to analytics. time to dive in.

    Singapore's government has also provided substantial support for the Living Analytics Research Centre. The Centre, a research partnership between Carnegie Mellon and Singapore Management University, "seeks to make Singapore one of the world's premier locations for the development and applied use of real-time consumer and social analytics, as well as one of the world's leading centres for computational social science related R&D and education."

Daily Kos: UPDATED: The HB Gary Email That Should Concern Us All - 0 views

  • According to an embedded MS Word document found in one of the HBGary emails, it involves creating an army of sockpuppets, with sophisticated "persona management" software that allows a small team of only a few people to appear to be many, while keeping the personas from accidentally cross-contaminating each other. Then, to top it off, the team can actually automate some functions so one persona can appear to be an entire Brooks Brothers riot online.
  • Using the assigned social media accounts we can automate the posting of content that is relevant to the persona.
  •  There are a variety of social media tricks we can use to add a level of realness to all fictitious personas

  • Really? I thought. How do we know if those are real people? Twitter has to be the easiest thing to fake and to automate with retweets and 180 characrer max sentences. To the extent that the propaganda technique known as "Bandwagon" is an effective form of persuasion, which it definitely is, the ability for a few people to infiltrate a blog or social media site and appear to be many people, all taking one position in a debate, all agreeing, for example, that so and so is not credible, or a crook, is an incredibly powerful weapon.
  • I believe there are many people though who will base their judgment on rumors and mob attacks. And for those people, a fake mob can be really effective.
