Since 1945, we had a single curriculum, with the 7th curriculum followed by the 2007, 2009, 2011, and 2015 curricula. How did the twelve curriculum changes affect students? No studies have been conducted on the impact of twelve different curricula on the growth of students in each school era. However, while there is no evidence that the current curriculum has been negatively affected by the current status of world history in Korea that does not mean that it had positive effects. In general, there are many negative views of education in Korea. However, Korea achieved remarkable economic growth after liberation as a result of education. There have been many changes in the content of the twelve courses, so that students often go through three or four curricula during their passage from elementary to middle and high school. Each is a different curriculum, but students take it personally as their own. and if the curriculum changes, students take it personally. The 21st century demands that students be creative. The curriculum should thus no longer be normative or formal. Non-normative content such as brain fade, talking, and graffiti should also be included in the curriculum.
