I would be surprised if any came from homes where no English was spoken or heard. Again, English is not Physics. When did they ever? That today is not a yesterday which nobody can recall is no kind of an excuse for not having expectations of teachers and of students. Yes, we can. How do you suppose Constructivism became such a plague? We can tell people how to teach and if some won't or can't follow direction, in Primary or in Secondary - if they find the required standards 'untenable' - then they should step aside for people more willing and more capable than they.
