I have no idea how Alexander Russo found this post, but it’s a good one. It’s titled The amazing truth about PISA scores: USA beats Western Europe, ties with Asia, and offers a great analysis of the recent PISA scores. The blog which published it says it gives “Kurdish-Swedish perspectives on the American Economy.”
It’s statistical analysis may be the best I’ve seen anywhere. However, I can’t say the same for its perspective on U.S. politics and education policy, which is a bit strange. But that part is only a very small portion of the post.
