So if I could imagine for a few minutes what the perfect school would of been for me, it might look like this. Grade school would be just as it was. I loved it. I loved learning then. I know I did. (when I started first grade, I was so excited to have homework. When I got home and sat down by my brother to do my home work, I must of made a comment that I was having fun, because he said something to the effect that, "It was NOT fun." I was young then, and I don't remember a lot from my youth, but I remember having this conversation very vividly, because I remember thinking there must be something wrong with me if I loved doing my homework, because my big brother, who I thought was very smart because he was older that me, did not like it.)
Then Jr. High would be different. There you would start learning more about yourself and what you where driven to do. You would get to take any class you wanted, and find your interests. And after a couple of years if your interest changed you would start at a beginning level for that subject. In my school structure there would still be some instruction in core subjects, but not to intense, unless it was your passion, and you could excel in those subjects. In my school there would be lots of learning about yourself, how I think and how that affects my being, how it plays apart of who I become and how it plays into what I am choosing for life long pursuits.
I can just picture myself enjoying a myriad of things until I find just the right things, and because of who I am, I might of been in a lot of different classes.
High School would be accelerated learning on the subjects that are driving you, and you would know they are driving you. But it could still be a place to start all over at the beginning of a new path depending on how your interest are changing.
