Annual U.S. self-flagellation over PISA test scores

<p>I’m not saying it cannot be done well in theory. The question is how it’s implemented. I just skimmed over the CA implementation, but it didn’t look encouraging to me, whereas the traditional separation of the sciences works pretty well. If anything, I think it would be more profitable to focus on integrating history with science and math with science. I know in my history classes, wars and treaties were the only subjects studied and the development of scientific ideas, the inventions they made possible and the impact of all this on history were largely ignored.</p>
