They're working with a bizarro Blank Slate theory according to which every student should simply be learning their math by themselves, and if they fail it's their own darn fault, or perhaps society's fault, or anyone else's fault, but certainly not the teacher's fault. Because the teachers all have Education degrees, and that's what they were told in Ed School. So don't anyone dare "demean" their job by suggesting that they have actual work to do in properly educating their students.
