Astronomy is taught in schools worldwide, but few schoolteachers have any background in astronomy or astronomy teaching, and available resources may be insufficient or non-existent. This volume highlights the many places for astronomy in the curriculum; relevant education research and 'best practice'; strategies for pre-service and in-service teacher education; the use of the Internet and other technologies; and the role that planetariums, observatories, science centres, and organisations of professional and amateur astronomers can play. The special needs of developing countries, and other under-resourced areas are also highlighted. The book concludes by addressing how the teaching and learning of astronomy can be improved worldwide. This valuable overview is based on papers and posters presented by experts at a Special Session of the International Astronomical Union.
