I agree. I’ve been a victim of inner city schools. They do not, and I mean DO NOT “teach”, they just make you repeat what the teacher’s doing.
I’m glad that my mother taught me while I was growing up because the schools would have made sure I would have fallen through the cracks due to my disability.
Unfortunately, in general, you are correct about the lack of any real teaching. There are some exceptions. In the few instances where you find some good teachers (and a supportive administration) you discover that inner city students actually respond well to a challenging curriculum. When things are too easy, it’s boring and creates a climate ripe for behavior problems.
