Education has evolved from 6th Century teaching by monks and priests, to the extensive curriculum that is available today. Charity schools taught the three 'R's. Acts of Parliament have had effects on education throughout the centuries. As the country grew in the Industrial Revolution new ideas developed with regard to educating children, and childhood itself. The 19th Century saw the introduction of Elementary schools, class sizes were large and made education available for 5-10 year olds. In 1900 50% of 3 and 4 year olds attended nursery. (Anning, A. Cullen, J. And Fleer, M. Early Childhood Education: Society and culture. Sage: (2004)). Whereas the main source of education for the working classes was through Sunday schools. Children were seen to develop through the stages of nursery, infant, junior and secondary. Boys and girls were separated and taught different subjects. Girls learnt how to become 'domestic' and be 'feminine' and boys learnt woodworking.Education has evolved over the last few Centuries. In the middle ages boys attended Grammar schools where punishment was severe. By the 15th Century, a third of the population could read and write. The 16th Century schools were called 'petty schools' where boys attended from 6 in the morning until 5 at night, for 6 days a week. The boys who were brighter went on to Oxford or Cambridge Universities. In the 17th and 18th Centuries the upper classes had private tutors. Boarding schools emerged for girls who learnt writing, music and needlework. The 19th Century saw the concepts of education through Froebel and Montessori. Upper class girls were taught by governesses, and boys attended Public schools. In 1880 education was compulsory, and 1891 saw the abolishment of fees. Children attended schools until the age of 12 in 1889. Schools were structured and included sport and games which were intended to provide competitiveness, negotiation and to enable children to mix with each other. (Brooks: 140). The 20th Century brought the minimum leaving age for compulsory schooling to 14. During the war years working class children attended elementary schools, middle classes attended Grammar schools and the upper classes attended public schools. The school leaving age was 15 in 1947 and this was again raised to 16 in 1972. The 1944 Education Act saw the introduction of the 11 plus, children went on to Grammar schools if they passed this exam and secondary modern schools if they were to fail. In the 1960's and early 1970's schools became Comprehensives.
