There are not enough such teachers to teach 1:1. There are not enough people who could be drafted to be such teachers either. It would require a lot of altruism to work as a teacher whereas there are much higher paying positions in the private sector. We have the technology to amplify a great teacher's lecture to millions. However, the education system relies on the model of interactive lectures given to a class of people of whom many are not acutely interested in the subject. Following that lecture, parents are drafted as involuntary teachers to help their kids with homework. If the student's parents have sufficient background, this works. Else, we end up with the situation where students continue to fall behind as their parents are unable to teach them. We need to bootstrap our students' learning to the minimally accepted level that sustains self-directed learning. I would define that as mastery of arithmetics as first phase and algebra as second phase. However, we are talking about mastery that does not require a review, which means spending more time on in-depth training without jumping ahead. Such classes should be separate from mainstream math classes so as to not to bore those of us who already have achieved that mastery. I am working on this.
