Following Children's Ideas in Mathematics
An unprecedented long-term study conducted by Rutgers University
followed the development of mathematical thinking in a randomly
selected group of students for 12 years - from 1st grade through high
school - with surprising results. In an overview of the study, we look
at some of the conditions that made their math achievement possible.

Are You Convinced?
Proof making is one of the key ideas in mathematics. Looking at
teachers and students grappling with the same probability problem, we see how two kinds of proof — proof by cases and proof by induction —naturally grow out of the need to justify and convince others.

The Law of Falling Bodies
With the conventional wisdom of the Aristotelian world view, almost everyone could see that heavy bodies fell faster than lighter ones. Then along cam Galileo. His genius deduced that the distance a body has fallen at any instant is proportional to the square of the time spent falling. From that, speed and acceleration follow with the help of a mathematical tool called a derivative.
