In early civilizations, people were educated informally: primarily within the household. As time progressed, education became more structured and formal. Women often had very few rights when education started to become a more important aspect of civilization. Efforts of the ancient Greek and Chinese societies focused primarily on the education of males. In ancient Rome, the availability of education was gradually extended to women, but they were taught separately from men. The early Christians and medieval Europeans continued this trend, and single-sex schools for the privileged classes prevailed through the Reformation period. In the late 19th and early 20th centuries, coeducation grew much more widely accepted. In Great Britain, Germany, and the Soviet Union, the education of girls and boys in the same classes became an approved practice. In the 16th century, at the Council of Trent, the Roman Catholic church reinforced the establishment of free elementary schools for children of all classes. The concept of universal elementary education, regardless of sex, had been created.[2] After the Reformation, coeducation was introduced in western Europe, when certain Protestant groups urged that boys and girls should be taught to read the Bible. The practice became very popular in northern England, Scotland, and colonial New England, where young children, both male and female, attended dame schools. In the late 18th century, girls gradually were admitted to town schools. The Society of Friends in England, as well as in the United States, pioneered coeducation as they did universal education, and in Quaker settlements in the British colonies, boys and girls commonly attended school together. The new free public elementary, or common schools, which after the American Revolution supplanted church institutions, were almost always coeducational, and by 1900 most public high schools were coeducational as well.[3]…
