The purpose of this study is to propose the current status and direction of improvement of online art museum-linked appreciation education based on surveys and interviews of art teachers. To this end, a mixed study was conducted to theoretically examine literature and prior studies on appreciation education linked to art museums, to investigate the operation status of online art museums in domestic and abroad, and to derive directions for improvement. The research method was designed with surveys and interviews, and the interviews, which are qualitative research materials, were put together to supplement the contents of the survey, which is a quantitative research material. In the case of the survey, a total of 42 copies were collected for middle and high school art teachers, and in the case of interviews, three art teachers participated. Research tools were modified and supplemented by researcher to be suitable for research based on teacher questionnaires developed by Joo Bo-young (2017) and Cho Seol-hee (2007) s questionnaires and analysis data to identify the actual status of online art museum-linked appreciation education and suggest improvement direction. The collected survey responses were conducted with frequency analysis through the SPSS Ver. 25.0 program, and the interview data were transcribed and categorized after recording. The results of the study are as follows. While art teachers positively recognize online art museums as exploratory learning spaces that can foster convergent thinking and have no space-time constraints, they responded that improvement is needed in terms of development and sharing of educational materials for continuous utilization. Through this study, collaborative research by relevant experts should be continued to expand the educational capabilities of online art museums, a digital space that enables constructive learning and to activate development of educational content that links online art museums to school appreciation education.
