In Erlanger's paper about Benny and the self taught math program, his main point was that it doesn't work and that teachers are necessary to guarantee a certain level of success. Benny was clearly a bright child since he managed to make up math rules that made sense to him and they worked for him about 80% of the time. His teachers didn't notice how much he was struggling because in comparison with the rest of the class, Benny was doing quite well with the program. His teachers had no reason to work individually with him unless he asked for help, and even he thought he was doing well so there was no reason to ask for help.
I think it's ridiculous to think that teaching mathematics principles can be done without the guidance of a real live teacher. If you don't know the correct math rules as a student, and you don't build upon those rules, you will not be able to progress very far. The high school student that I tutor had a very "hands off" math teacher last semester. Now she has a new teacher, and when I come to help her with her homework, most of it is finished ahead of time becomes she's gaining relational understanding at school just because her new teacher is involved with his students.
