How to teach mathematics

From The Washington Post, 30 May 2011:

Eugene A. Geist, an associate professor at Ohio University and the author of Children are born mathematicians … advises teachers to have students focus on learning mathematics processes, rather than relying on the answer keys in a textbook, which can undermine both their own and the teacher’s confidence in their math skills.

“If I give the answer, you immediately forget about the question. If I don’t give you the answer, you will still have questions and you will be thinking about the problem long after,” he said.
