I think the innocence behind that statement comes from the difficulty a teacher will face if s/he must teach students with diverse learning needs (child A is learning timestables while child B has moved on to trigonometry).
That said, I think a teacher should suck it up for the sake of students in this sort of situation. At worst, we find ways to reorganize teachers and students based on students' self-progress.
Clearly students need to be placed into classes based on their ability. There is no goddamn reason why student A and student B should be in the same class, or even at the same school.
Agreed. Maybe techies gotta band together and create a better online infrastructure for the whole homeschooling process. Just combine Meetup with Khan Academy and you can have decentralized collaborative homeschooling@!
