Teaching has evolved significantly over the centuries, with early methods like the Socratic dialogue used by Socrates and Plato, contrasting with the medieval lecture format that emerged in universities around the 1200s. The term "university" originates from the concept of a collective of colleges, emphasizing a universal approach to education. In the U.S., the university structure often mirrors the European model, featuring specialized colleges while promoting a communal living environment for students. Oxford and Cambridge utilize a system where lower-level courses are typically large lectures supplemented by individual tutoring, while upper-level education may focus on personalized instruction. Overall, the evolution of teaching methods reflects a transition from informal discussions to structured lectures and specialized tutoring.
