Teachers disliked him, because they knew how easily he picked up information. I'm a teacher, and this is one of the things that frustrates me deeply about our education system. I welcome students like this; they're so much fun to work with. But I usually have to make them feel accepted before I can begin to work with them. I teach in a small alternative high school, and by the time bright students get to me, they're…

Learning the subject matter is secondary--the key to succeeding at this institution is to do things in the expected way, at the expecte…
Some people can intuitively do division in their head for simple problems, but if they don't learn the mechanical algorithm for it, they are unable to do more complex division.

There is a point to learning an algorithm, even if you already know the answer.
