Georges Charpak has taken the initiative for a complete reform of our methods of science teaching. He proposes a teaching method based on creativity and problem-solving, instead of the old theoretical, book-based approach. This book recounts the experiences of two teams of French educators in a research institution created by Leon Lederman in Chicago, and the lessons which we can take from their experiences. Pollens shows that to learn is to discover, and that it is in discovering that one learns.

Georges Charpak is a Nobel laureate in physics, and the author of La vie à fil tendu and Feux follets et champignons nucléaires, both published by Editions Odile Jacob.
