Much of East Asian History focuses on China and Japan. Korea is often an afterthought, or taught as a tributary state under the influence of China. Also, much of Korean History is taught with a modern lens, where Korea is a victim of China and Japan. This lesson will introduce students to the cultural achievements of Korea during its Early Modern Era, showing that Korea has important cultural achievements of its own and is not always influenced by other cultures, but has its own history. It will focus on Moveable Type Printing, King Sejong and Hangul, Admiral Yi and Turtle Ships, and citizen governance under the Joseon. These topics tie into the Iowa Standards about cultural advancement as well as those about individuals impacting history. They also tie into change over time and causation standards in the C3 Framework.
