Recently, curriculum studies, including key competencies, curriculum competencies, and key concepts for enduring understanding as big ideas, are underway. Through the key competencies and curriculum competencies of the 2015 revised curriculum and the 21st century learning framework of the OECD Education 2030 project, it is necessary to re-conceptualize and conceive the competency and curriculum framework.
Thus, it is necessary to explore subject competency as the essence of the subject. In the current competency-based curriculum, the balance of knowledge, function, value and ethics should be considered more, and the close connection between art theory and practice should be more important in terms of the nature and value of the subject. This study examines art subject competencies focusing on the current curriculum for the purpose of pluralistic understanding and exploration of art subject competencies through theoretical and practical knowledge, activist approaches, humanistic approaches, and ontological approaches. In conclusion, the national art curriculum should explore the ontological approach and art theory as knowledge through new educational changes, the principle of formability as a subject competency, and the materiality that enables it.
