Introduction The International Astronomical Union (IAU) was founded in 1922 to “promote and safe- guard astronomy ... and to develop it through international co-operation”. The IAU is funded through its National Members. Almost all of the funds supplied from the dues are used for the development of astronomy. One of the 40 IAU “Commissions” is Commission 46, formerly called The Teaching of As- tronomy and more recently, at the 2000 General Assembly, renamed Astronomy Education and Development. It is the only Commission that deals exclusively with astronomy education; a pre- vious Commission 38 (Exchange of Astronomers), which allocated travel grants to astronomers who need them, and a Working Group on the Worldwide Development of Astronomy, have been absorbed by Commission 46. The Commission’s mandate is “to further the development and improvement of astronomy education at all levels, throughout the world”. In general, the Commission works with other scientific and educational organizations to pro- mote astronomy education and development; through the National Liaisons to the Commission, it promotes astronomy education in the countries that adhere to the IAU; and it encourages all programs and projects that can help to fulfill its mandate. 230
