Physics researchers, accustomed to being at the forefront of technology, have been deeply affected by the computer revolution. This effect has serious implica*ions for what is taught and how it is taught in the physics classroom. This conference was organized to allow physics teachers and software developers in physics education to come together and see the state of the art in using computers to teach physics. The conference included 39 invited lectures and 122 contributed presentations. It introduced a number of innovations in the hope of increas ng interactions and stimulating futlire conta -s. -
