This PISA test is ridiculous as a standard to measure the general intelligence. 400,000 is not a very big sample size in certain countries. It seems that this method measures more of the homogeneity of the education level of a country rather than the smartness of its students. I'm curious about the sampling method of this test, it's really hard to select a representative sample among diversity such as U.S. That being said, I do agree with the way a lot of classes are taught in American public schools. Especially the projects where students "glue things on a poster for an hour", mindless things like that really waste time and energy better used in something else. And I cant help but think that Finnish kids really dont have much to do compared to people at other countries? They might as well do really well in their studies!
