Why is Obama against testing students?

Obama on testing ...

"By twelfth grade, our children score lower on math and science tests than most other kids in the world. "
...
"And by the way - don't tell us that the only way to teach a child is to spend most of the year preparing him to fill in a few bubbles on a standardized test. Don't tell us that these tests have to come at the expense of music, or art, or phys. ed., or science. These tests shouldn't come at the expense of a well-rounded education - they should help complete that well-rounded education. The teachers I've met didn't devote their lives to testing, they devoted them to teaching, and teaching our children is what they should be allowed to do." ... source.

Do you think countries like South Korea score higher than the US on tests because they focus on a well rounded education?

Tell me, how do you teach a kid to answer this questions, without teaching them math?

You see ... teaching kids how to "fill in a few bubbles on a standardized test" requires that you teach them the subject matter of the test ... stop making excuses for failing education & schools.
