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.

This book was first published in 2007. Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, flares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them. This book provides a concise overview of variable stars, including a historical perspective, an introduction to stars in general, the techniques for discovering and studying variable stars, and a description of the main types of variable stars. It ends with short reflections about the connection between the study of variable stars, and research, education, amateur astronomy, and public interest in astronomy. This book is intended for anyone with some background knowledge of astronomy, but is especially suitable for undergraduate students and experienced amateur astronomers who can contribute to our understanding of these important stars.
