Knewton's sales representative, Jose Ferreira, is making some big claims. "We literally have more data about our students than any company has about anybody else about anything, and it’s not even close.... We literally know everything about what you know and how you learn best, everything." Except, responds Philop Kerr, it's not that simple. "The basic premise here," he writes, "is that the more data you have, the more accurately you can predict what will work best for any individual learner" But is this true? Not without good theory. "Knewton’s claim that they know how every student learns best is marketing hyperbole and should set alarm bells ringing." Moreover, I would add, it should set everyone's privacy alarm bells ringing. Do we really want textbook publishers to know everything about us?
