There are quite a few examples of very misguided educational strategies.

Whole Language[1] failed so many students, but had significant funding and guru-level support for decades. Brain Gym[2] is regarded as pseudoscience. Even Discovery Learning has had serious detractors.

Liljedahl's "Building Thinking Classrooms" is the current poster child for this. Hugely influential in educational circles, but inconsistent with most of the reproducible research in cognitive science and likely quite deleterious to learning.

Bingo! It's exactly stuff like that that I had in mind. And I also pity the parents whose kids have to endure this nonsense instead of getting a proper education. I mean, you basically have no power. You give your kids to whatever the government's idea is of an education and all you can do is watch helplessly from the side.
