She (and the locals) are very negative about South Korea, but very positive about Poland and Finland. And she points out that all three countries use a fraction of the budget that the US does on education, with much better results.
She also points to the fact that outside of the United States, extracurricular activities -- not to mention sports -- are not a part of the school curriculum. If you want to play basketball, then that's great, but don't expect your high school to care about it, because their job is to worry about your education, not sports.
I have a PhD in learning sciences (roughly "technology and education"), live in Israel, and have three children. And the way that the schools here run depresses me more each year. As the book points out, and as we probably already know, the forces in charge of schools (e.g., politicians, teacher unions, and taxpayers) are basically aligned against any real reform. Gimmicks such as technology look great, but are virtually useless -- a form of "education theater," as it were.
Israelis talk nonstop about class sizes, but I think that a much bigger problem is that we pay our teachers nothing, and give them no respect or power -- and are then surprised that the quality of teachers has declined precipitously.
From everything I can tell, we would do well to give teachers massive salary increases, then make it hard to become a teacher and easy to fire bad ones. Then give the teachers huge freedom to do what they want. And yes, this will cost money (which the taxpayers don't want to hear), but on balance it seems to work for most people, most of the time.
