The results of the third National Assessment of Educational Progress NAEP show an apparent lack of understanding of fractions by nine- thirteen- and seventeen-year-olds. Similar trends were observed in the first, the second, and the recently completed fourth National Assessments Carpenter et al.

What kinds of biases and erroneous preconceptions do we have? Two of my favorite historic discoveries are Einstein's discovery of relativity and Cantor's discoveries of some of the most basic rules of infinities.

These discoveries are remarkable in that neither involved long, involved, complicated computations. Both are fairly simple, in retrospect, to anyone who has studied them.

But both involved "thinking outside the box" par excellence -- i. As philosopher John Culkin said, "We don't know who discovered water, but we are certain it wasn't a fish. Errors in Communication Some teachers are hostile to questions. That is an error made by teachers. Teachers, you will be more comfortable in your job if you try to do it well, and don't think of your students as the enemy.

This means listening to your students and encouraging their questions. A teacher who only lectures, and does not encourage questions, might as well be replaced by a book or a movie. To teach effectively, you have to know when your students have understood something and when they haven't; the most efficient way to discover that is to listen to them and to watch their faces.
