    1. They have a very simplistic view of the activity being monitored by only distilling it down into only a few dimensions for the rule to interrogate

      Number of dimensions need to be large. In normal database systems these dimensions are small.

    1. often private companies whose technologies power the systems universities use for predictive analytics and adaptive courseware
    2. the use of data in scholarly research about student learning; the use of data in systems like the admissions process or predictive-analytics programs that colleges use to spot students who should be referred to an academic counselor; and the ways colleges should treat nontraditional transcript data, alternative credentials, and other forms of documentation about students’ activities, such as badges, that recognize them for nonacademic skills.

      Useful breakdown. Research, predictive models, and recognition are quite distinct from one another and the approaches to data that they imply are quite different. In a way, the “personalized learning” model at the core of the second topic is close to the Big Data attitude (collect all the things and sense will come through eventually) with corresponding ethical problems. Through projects vary greatly, research has a much more solid base in both ethics and epistemology than the kind of Big Data approach used by technocentric outlets. The part about recognition, though, opens the most interesting door. Microcredentials and badges are a part of a broader picture. The data shared in those cases need not be so comprehensive and learners have a lot of agency in the matter. In fact, when then-Ashoka Charles Tsai interviewed Mozilla executive director Mark Surman about badges, the message was quite clear: badges are a way to rethink education as a learner-driven “create your own path” adventure. The contrast between the three models reveals a lot. From the abstract world of research, to the top-down models of Minority Report-style predictive educating, all the way to a form of heutagogy. Lots to chew on.

    1. I could have easily chosen a different prepositional phrase. "Convivial Tools in an Age of Big Data.” Or “Convivial Tools in an Age of DRM.” Or “Convivial Tools in an Age of Venture-Funded Education Technology Startups.” Or “Convivial Tools in an Age of Doxxing and Trolls."

      The Others.

    1. “fundamentally if we want to realize the potential of human networks to change how we work then we need analytics to transform information into insight otherwise we will be drowning in a sea of content and deafened by a cacophony of voices”

      Marie Wallace's perspective on the potential of bigdata analytics, specifically analysis of human networks, in the context of creating a smarter workplace.

    1. your system is able to flag at least a critical mass of videos taught in the Mueller method as having a bigger educational impact on the students the average educational video by some measure you have identified

      Sounds like a neat description of what many Big Data enthusiasts are actually trying to do. Some Big Data positivists do go so far as to claim that the “inference engine” will eventually be powerful enough to find meaning. But this distinction is within the Big Data field, not between it and other fields.

    2. sufficiently rich information
    3. It’s educators who come up with hypotheses and test them using a large data set.

      And we need an ever-larger data set, right?

    4. Some were done this way on purpose but based on intuitions by classroom teachers.

      Isn’t Big Data partly about reverse-engineering these intuitions?

    5. hadoop thingamabob back end
    6. a good example of the kind of insight that big data is completely blind to

      Not sure it follows directly, but also important to point out.

    1. As long as the content in SmartBooks is locked down, then it is possible to run machine learning algorithms against the clicks of millions of students using that content. To the degree that the platform is opened up for custom, newly created books, the controlled experiment goes away and the possibility of big data analysis goes with it.

      Not sure it follows…

    2. they are making a bet against the software as a replacement for the teacher and against big data

    1. Ein Start-up aus den USA testet ein neues Hilfsmittel zur Minimierung der Folgen von Datendiebstählen: Es prüft, ob in versteckten Teilen des Web fremde Daten zum Kauf angeboten werden.
