Disassociate government from the school system so you have teachers of science arguing about what to teach rather than politicians and voters; most of which have no idea what they are talking about or have reasons (constituency, see "no idea what they are talking about") to disassociate themselves from the truth.
It will never be right with non-scientists directing what scientists teach.
I'm gonna go out on a limb here and say it's a rock.
