2. Excellent information. Thanks!

Side note: I have started employing "Singapore Math" techniques in my second grade classroom to bolster mental math and number sense. I am seeing great results. My point is that, in math at least, there may be methods like Singapore Math as well as their focus on test-taking that are helping the Singaporians outperform much of the world. In my opinion and experience, the U.S. has done a crappy job in math education.

But your post has helped my understanding in the latest round of international test data. It occured to me that comparing the international data makes about as much sense as comparing data among U.S. school districts in all of their demographic diversity.
