I tend to think learning by doings main issue is it wastes time.

If as an adult you don't have a lot to learn doing is fun so why not. But if you want to train hard, back to boring.

There's different research out there, basically the doing side was introduced without research hence the scramble to work out the better method.

I think it is compounded by the fact experimental schools often do better, since they are putting in effort. A known performance enhancer.
