For the last 34 years, I have taught at University High School, in Urbana, Illinois. During this time I have created a 4-year world history curriculum that breaks down as follows: Subfreshmen (7th and 8th grades combined): Prehistory and ancient civilizations, including India, China, and Japan. Freshmen: Western civilization and the Islamic world to 1500 Sophomores: World history from 1500 to 1945 Seniors: the world since 1945. All of these, except the senior course are required. The elective senior course is consistently filled to capacity of 30, usually with a waiting list.
