Most education majors are aware of that despite the fact that A/B testing is ubiquitous, it lacks serious reliability and/or validity as a serious methodology for evaluating teaching techniques or evaluation models for those techniques. It's a sad comment on the state of online training that most methodologies end up being evaluated in this fashion. Teachers use A/B testing because it's quick and easy as a way of putting some kind of data point in a teaching or evaluation process; it's time for online training to understand this and work to rise above such primitively approaches in creating new teaching techniques involving the increasing use of technology. It's only in this way that online education can truly compete with conventional education practices.

In America, wi-fi access for "free" is a joke. I spent 2 hours in a McDonald's recently trying to simply upgrade the OS on my phone, only to have to quit before I was finished to grab transport back home. It's remarkably easy for the have in the US to assert that no one goes without in our "great" country, when the fact of the matter is that unless you spend time to access so called giveaways, you have no clue as to how marginal these things can be. Spend a month trying to work through your day on free wi-fi, then brag about the wonders of American life.
