In the early 20th century, a number of Korean textbooks on Hanmun (Korean Literary Sinitic) were published. These textbooks introduced new ways of understanding and teaching Hanmun grammar. Some of these innovations are highly original and explore experimental ideas. The hŏsa/silsa paradigm (usually translated as “empty” and “full words” in English) forms the basis of many pre-modern and early modern Literary Sinitic grammars, but these concepts are understood in different ways in each of them. The conventional understanding that hŏsa are ‘function words’ does not sufficiently explain their descriptive usage in early modern Korean grammars. This article investigates how the concept of hŏsa/silsa is understood in Korean Literary Sinitic grammars and textbooks from the Late Chosŏn and Colonial periods, and how it is applied in teaching. Although these old grammars are clearly outdated in many ways, the grammatical concepts they present still hold some didactic value. Some of these concepts, particularly the hŏsa/silsa concept, are still useful for teaching basic Literary Sinitic courses.

The early 20th century was a time of rapid change in Confucianism. As East Asian intellectuals actively learned from the West in the process of modernization, Confucian classical education lost its dominant position. Western learning changed the education system in East Asia, and textbooks on self-cultivation replaced traditional Confucian literature such as the Four Books and Five Classics, the children’s textbooks and the family rules, and became the textbooks for the moral education curriculum in the new academic system. Although these textbooks are still referred to as books for self-cultivation, the knowledge has been reconstructed in the Western educational framework, and their contents are not limited to moral education. This article analyzes the transformation of Confucian knowledge in Korea under the influence of Western learning based on the theoretical explanations and the school textbooks in the Korean Enlightenment Textbook Series. It reveals that Korean intellectuals established a curriculum for moral, intellectual, and physical education, as well as a curriculum for health education, which brought the Chinese and Western cultures together from conflict to coexistence at the beginning of the twentieth century.
