David Wiley, iterating toward openness, Mar 27, 2012
Commentary by Stephen Downes

Sure, this is the data in, but what does the analysis loom like? David Wiley: "“Browser history as high stakes exam.” If an entity like ETS can establish predictive validity around different performance / behavior patterns and college completion or success, one can easily imagine submitting their usernames for Google Web History, Facebook, Twitter, Delicious, Blogs, Google Reader, YouTube, etc. IN PLACE OF taking a four hour high stakes exam like the ACT or GRE. Why make a high stakes decision based on a few hundred data points generated in one morning (when you could be sick, distracted, etc.) when you could get 1,000,000 data points generated over three years?"
