  • Todd shared from I Got Schooled: The Unlikely Story of How a Moonlighting Movie Maker Learned the Five Keys to Closing America’s Education Gap by M. Night Shyamalan
    If America’s scores were limited to those from schools in districts in which the poverty rate was less than 10 percent—Finland’s poverty rate is less than 4 percent—the United States would lead the world, and it wouldn’t be close: 551 on the latest PISA test, compared to Finland’s 536, or South Korea’s 539. In fact, if all you did was exclude the American schools that have student bodies that are more than three-quarters poor, U.S. schools would still score 513, just behind Australia, but ahead of the Netherlands, Belgium, Sweden, Germany, Iceland . . . well, you get the picture.

  • Todd shared from David and Goliath: Underdogs, Misfits, and the Art of Battling Giants by Malcolm Gladwell
    In four countries—Australia, Hong Kong, Scotland, and the United States—our identification strategy leads to extremely imprecise estimates that do not allow for any confident assertion about class-size effects. In two countries—Greece and Iceland—there seem to be nontrivial beneficial effects of reduced class sizes. France is the only country where there seem to be noteworthy differences between mathematics and science teaching: While there is a statistically significant and sizable class-size effect in mathematics, a class-size effect of comparable magnitude can be ruled out in science....

  • Todd shared from David and Goliath: Underdogs, Misfits, and the Art of Battling Giants by Malcolm Gladwell
    The first is that much of what we consider valuable in our world arises out of these kinds of lopsided conflicts, because the act of facing overwhelming odds produces greatness and beauty. And second, that we consistently get these kinds of conflicts wrong. We misread them. We misinterpret them. Giants are not what we think they are. The same qualities that appear to give them strength are often the sources of great weakness.

  • Todd shared from The Sports Gene: Inside the Science of Extraordinary Athletic Performance by David Epstein
    When Finch subsequently visited Alex Rodriguez, the reigning MVP, Rodriguez watched over Finch’s shoulder as she threw warm-up pitches to one of his team’s catchers. The catcher missed three of the first five throws. Seeing that, Rodriguez, to Finch’s disappointment, simply refused to step into the batter’s box.
