Traditionally, archives, libraries, and museums have been known to have common responsibilities in providing public service, despite of their differences in the nature of holdings. Recently, these institutions, which are keeping archival materials, increasingly collaborate with each other to provide effective integrated user service in educational programs. The study highlights the importance of collaboration among cultural institutions and analyzes the exemplary cases inside and outside Korea. By analyzing the current educational services conducted by the institutions, focusing on weaknesses and strengths, the authors mention that the analysis results can be referred to them when developing a model of educational services. Based on the analysis, this study finally offers a plan to activate the collaboration of cultural heritage institutions in Korea and develop a model for educational services using the ADDIE model.
