According to my (chinese) wife, ABC = "American-born Chinese", not "American Born in China" (/nitpicking)
Ms. Bloom has inadvertently fingered the major cause of educational decline in America in recent years. The "American way in recent years" with respect to education is a national tragedy.
Perhaps the Chinese students know that if they need to learn physics, their questions about physics might be in the book (not a guarantee, but a better bet), rather than hearing Suzie describe how she "feels" about those itty-bitty things that can't be seen.
Your wife is correct. Is she an ABC?
