The World Health Organisation has developed a concept of ecological health- a notion that health, using a broad definition, is a product of the societies and environments in which we live. It is the aim of the WHO to achieve "Health for All by the Year 2000." This reform agenda incorporates education as a tool for social change. This study investigates the role of education in social change, with local and global health as an objective. The background to the development of this concept is outlined, as are the social issues that make this such an important perspective. Theories of social formation and the role of the school in relation to society are discussed, and the research that confirms that schools do "make a difference" reported. Definitions of change, factors affecting social change and models of change are described. Factors relating specifically to educational change are outlined and related to examples of educational change, designed to promote social change, in Australia. Case studies, composed of descriptions of schools written by staff members to illustrate the process of working towards becoming "Healthy School Communities" and transcripts of interviews, are analysed to determine the extent and type of change that is taking place within each school, and how the changes are happening. Schools reported changes to attitude, understanding, policies and practice. The analysis is then discussed, and the conclusion reached that this construct of education has some useful conceptual frameworks, for the cultural changes that are occurring in Australia and other Western cultures.
