This study was conceptualized with the idea that developers can contribute to sensitive stages of a child’s development by creating a standard that can be used when developing serious games based on the Nuri curriculum. The Nuri curriculum is an integrated curriculum for early childhood education initiated by the Korean government in 2011. To accomplish this, the game materials were selected based on the five areas of the Nuri curriculum. The standard of game development was based on the Nuri curriculum’s organization and teaching and learning methods. And these concepts were applied for the development of a serious game named Exploration Adventure.
