As the mother and "learning coach" of our daughter (th3w01f is my other half) I truly enjoyed seeing first hand what she was learning. I was able to see exactly what she struggled with and we could spend more time on those subjects. On the other side, we got to work ahead as far as we wanted on subjects that she excelled in. With the kids going to school full time this year I've truly missed being able to work ahead certain days so that we can do other enriching activites on other days. As long as we make our outing educational, we can log the hours with the school.
Another thing that has prompted us to consider moving both of our kids to online school next year was our bully experience. Our daughter handled it better than most adults would have but the school has done nothing about this kid. This is the kid's third school in 3 years because her behavior is so bad. I know we can't shelter the kiddos from everything and I don't want to. But like Spyder said the schools are so liberal these days that the kids have no concept of punishment, failure, or even success. You can neither have nor appreciate success unless you get the opportunity to have and appreciate failure.
