Commission 46 is dedicated to Teaching of Astronomy. Commission 46 can be seen as an extension of the IAU Executive Committee in the sense that each adhering country has appointed a national representative to the Commission. National Representatives maintain liaison between the Commission and the home country, and write national triennial reports on development of astronomy on their nations. Other IAU astronomers, with special interest in education, can become regular individual members of the Commission. Non-IAU members can be invited by the Commission to serve for one triennial term. Commission 46 considers that one of its major duties is to contribute to enhance astronomy education in developing countries. The Newsletter, the International School for Young Astronomers, the Visiting Lecturer Program and the Travelling Telescope are examples of such activities administered by the Commission. The strength of Commission 46 comes from the hard work that its members do in order to promote astronomy education worldwide.
