School curricula give teachers the opportunity to lead students to learn in a community and put abstract theory into practice to achieve social needs and real connection to the society. Taiwan's indigenous tribes developing tourism has made the actual living area of tribal people overlap with tourists' sightseeing stage, and quite a few issues have derived because of this. Meanwhile, residents actively care for local people, matters and objects to coagulate consensus, which makes interaction between a university and community more important. Through participatory action research, the study probed into the roles, missions, interaction methods and participatory processes of members of Laiji Tribe Design Workshop. The results show that: 1.With the method of “intersubjectivity,” members cooperated to solve challenges they faced; 2.The participatory process of the complete design workshop for experiential learning in communities included 13 stages and 35 steps. However, some of them repeated and had leaping progress or returned to previous ones; 3. Serving as an interactive learning method between a university and community, the workshop was a small yet continuous mode for co-creation empowerment.
