Big data, stupid decisions #LAK12

Commentary by Bianka Hajdu (Bianka Hajdu) on link by sharonslade, Big data, stupid decisions #LAK12, Jan 26, 2012.

One of the main points of Ipeirotis' presentation was that the meaning of data depends on the contexts and so, for measuring, it is also necessary to consider context. Poor grammar in product comments results in less sales of that product in the case of Amazon. In your example, which I find interesting, poor grammar in tutor feedback should be also linked to something students do in the course of their relationship with the tutor. Perhaps the frequency in their interaction could be an indicator? Anyway, I think analytics linked to texts may turn out to be an important issue in learning. (Hits Today: 4502 Total: 4502)
