The feedback that students get in this kind of model is VERY binary, is the problem-- they invest a lot of time (as noted above) and then the result is either "yes!" or "no-- try again."
Think that fuels perfectionism much?
... makes it even HARDER to such kids to admit that they need help, accept constructive criticism, or maintain a growth mindset.
This is precisely the approach our math harpy takes. DD was supposed to redo "incorrect" homework problems last night. I looked at them. The answers to 3 out of 6 were correct and so was the procedure she used. But the harpy marked them wrong because they hadn't been formatted correctly ("skip a line here; write this kind of line instead of that kind of line, etc.").
One of the particularly noxious things about our harpy is that sometimes she expects the kids to follow the directions in the book and sometimes she doesn't. The distinction between the two is hard to figure out. Yet she writes nasty notes on their homework saying, "Follow the directions!!" when they do a problem her way instead of the book's.
And as you noted on the first page of this thread, the teachers (or babysitters in some cases) we're all complaining about will be defended by the people in charge of them.
