Teaching is a bizarrely evidence-free field. It's as if there's an active aversion to finding out whether a method or tool works or not. I can't think of any field where so little is known, where there is such a paucity of good data.
We've been spending hundreds of millions on putting technology in classrooms, without a shred of evidence that it improves learning outcomes. As a society we do plenty of things that we know not to work, like imprisoning people or criminalising drug users, but at least we've got enough data to say that they don't work.
