Have you tried one of these edutech apps? They're mind-numbingly boring and move at a snails pace. Meanwhile YouTube is lurking in the background. And if that's locked down you can always chat with your friends in a Google Doc (trust me, it happens). And the teacher now has to babysit 25 kids rather than actually developing a class that might be more engaging.
There's no comparison with an engaging Youtube lecture.
