This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book presents an account of the development of girls’ private education and gathers together data on current educational trends in girls’ education. It examines the interlinked development of music-teaching and sport and physical education through the second half of the nineteenth century and into the twentieth. The book then investigates the somewhat similar dilemmas that faced private girls’ schools in including science in the curriculum during the late nineteenth and early twentieth centuries. It also examines the ways in which girls’ private schools have been portrayed to others in the various book-length histories that have been written about them. The book presents the results of a comparative study that investigated the political attitudes and values of girls, focusing on both the content and process of their political socialization.
