In November 2016, the culture of Jeju Haenyeo (women divers) was listed on the UNESCO Representative List of the Intangible Cultural Heritage of Humanity thanks to the great efforts from many experts to introduce the excellence of the culture of Jeju Haenyeo. Even before the registration, Jeju National Museum had tried some experimental education programs by using some intangible cultural heritages of Jeju Island. Based on the Jeju Chilmeoridang Yeongdeunggut inscribed in 2009 on the UNESCO list, the museum carried out an adult program on Jeju’s myths and shamanistic beliefs with theories, practices and field survey. To support the local efforts for putting the culture of Jeju Haenyeo on the list, the museum also developed a thematic teaching material while adding educational values on the culture. Finding ways to strengthen cooperation between local museum and public education, the museum paid attention to the needs of schools who wanted to include the nation’s history and culture in their school curricula. As a local museum, we were asked to develop and distribute educational contents based on Jeju’s local culture. Among many cultural heritage, the museum focused on the culture of Jeju Haenyeo. We studied and collected documents and set a guideline for terminology. We found Haenyeo-related stories in the island’s mythologies and put them in appropriate order. Thereafter, we developed teaching materials, worksheet and experience programs. We explained the history of haenyeo with the change from janmyeo (diving women) to haenyeo (women diver), the women divers in traditional paintings, the story of coral haenyeo, the community of haenyeo, the spatial functions and meaning of bulteok, the wetsuits and tools, the migration of ‘chulga’ haenyeo, the songs of haenyeo, and the role of haenyeo in the Japanese colonial period. We also developed a worksheet for better understanding and even a special tool kit to teach the process of making a wetsuit. The teaching material was first used for a program entitled "Jeju Haenyeo, the protectors of the sea" during the winter vacation in 2016. Since March 2016, the program has distributed to local schools in Jeju in the linkage with certain subjects like social studies and moral education. Some specialized schools are interested in using the materials for their study projects on local cultural heritage. In particular, teachers have shown great satisfaction with the program because they were able to utilize various practical resources in their curricula. The significance of developing the teaching material is to arouse interests in preserving local cultural heritage and to make local children feel proud. While using the materials, students can experience and understand the community of Jeju Haenyeo and introspect themselves from the context of school community. It is highly expected that students can experience the value of coexistence based on respect and trust. In the future, the museum plans to develop other teaching materials based on local cultural heritage after collecting ideas and opinions from schools and local community.
