I actually agree with this, kids are pushed to grasp concepts before they have mastered the basics. In my opinion this is why kids get left behind. 4 years of the basics bored or not after that they will excel at what they are suited to when you go to the next level. I think we are creating social division the way we are doing it now.
Every person is important to society. I think a good grasp of the basics enforces that on every level.
I know that I need a lot of people that are either better at, or willing to do things that I can't.
I think teaching in our diverse society is harder than it has ever been, I always try to be supportive of educators, they are not allowed to be diverse in their methods and I think that it is wasteful of their talents.
