This paper examines discussions and practices in character reinforcement-centered art education, focusing on the characteristics of the nature of art. First, it is discussed, in terms of character education, about what the unique and natural characteristics of the contents of art subject can contribute to human development. Next, the lesson contents reflecting this view are selected and teaching approaches to the contents are suggested. The discussions are presented with five suggestions for the lesson contents that: (1) embody from a discussion about the mutual relationship between aesthetic sensitivity and moral sensibility, and between aesthetic awareness and ethical awareness; (2) plan discussions on how the uniqueness of creation and interpretation in art can promote self-esteem, followed by instructions that embody the discussions; (3) conduct character education that can develop openness, critical thinking; (4) carry out the discussion that critical reading of a visual culture can promote critical thinking and moral judgement ; and (5) conduct discussions on how communicating with art images can give opportunities to reflect on oneself and practice character education. From these ways that reinforce the lessons centered on character in art subject, there are two implications. They are: (1) the art textbooks and curriculum should reveal the contents that contain moral lessons for character education, as well as the nature of art(education) ; and (2) it is necessary to continue teacher training education that help teachers understand the nature of art education and the appropriate teaching contents and methods.
