controlling church challenged the focus of the schools, and the curriculum and language of instruction waxed and waned. From 1100, With the growth of the towns, grammar schools 'free' of the church were founded, and some church grammar schools were handed over to the laïty. Universities were founded that didn't just train students for the priesthood. Renaissance and Reformation Whereas in mainland Europe the Renaissance preceded the Reformation, local conditions in England caused the Reformation to come first. The Reformation was about, among other things, allowing the laïty to interpret the Bible in their own way without the intervention of priests, and preferably in the vernacular. This stimulated the foundation of free Grammar schools- who searched for a less constrained curriculum. Colonialisation required navigation, mensuration, languages and administrative skills. The laïty wanted these taught to their sons. After Gutenberg1455 had mastered moveable metal type printing and Tyndale had translated the Bible into English (1525), Latin became a skill reserved for the catholic church and sons of conservative nobility. Schools started to be set up for the sons of merchants in Europe and the colonies too- for example Boston Latin Grammar School (1635). Comenius (1592–1670), a Moravian protestant proposed a new model of education- where ideas were developed from the familiar to the theoretical rather than through repetition, where languages were taught in the vernacular and supported universal education. In his Didactica Magna (Great Didactic), he outlined a system of schools that is the exact counterpart of many western school systems: kindergarten, elementary school, secondary school, six-form college, university. Locke's Some Thoughts Concerning Education (1693) stressed the importance of a broader intellectual training, moral development and physical hardening. The grammar schools of the period can be categorised in three groups: the nine leading schools, seven of them boarding institutions which maintained the traditional curriculum of the classics, and mostly served 'the aristocracy and the squirearchy' ; most of the old endowed grammar schools serving a broad social base in their immediate localities which also stuck to the old curriculum; the grammar schools situated in the larger cities, serving the families of merchants and tradesmen who embraced change. Industrialisation During the 18th century their social base widened and their curriculum developed, particularly in mathematics and the natural sciences. But this was not universal education and was self-selecting by wealth The industrial revolution changed that. Industry required an educated workforce where all workers
