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.
Inventing Notations
We learn how to foster and appreciate students' notations for their
richness and creativity, and we look at some of the possibilities that
early work on problems that engage students in creating notation
systems might open up for students as they move on toward algebra.

Learning As Synaptic Change
This module presents researchers investigating the structural changes involved in learning. Research conducted at the Pasteur Institute in Paris shows that the learning process involves the formation of new brain connections and the elimination of others. Other researchers dispel the myth of brain loss in aging, present evidence of changes at the cellular level, and revi
Perception: Inverted Vision
The peculiar image inversion process that takes place in the normal visual system is examined in this module. The program traces the experiences of an art student who volunteers to wear lenses that invert her visual world, connecting the adaptation process she undergoes with how the visual system functions.
