This study aims to find the way to develop a new form of mutual help in the community by anthropological methodology and action research, through the exploration of the cultural elements of the community and then constructs an ecological community support network on these grounds. In the study, the researcher accompanied the students who came from the disadvantaged minority to discover their self-value and to develop themselves based on their potential. Meanwhile, the researcher learnt applying the power of community to perform and to practice the idea of the self-education, being a voice for the disadvantaged children and youth. In the process of this action research, the researcher attempted to help the disadvantaged students to accumulate their social capital and thereby constructed a student-centered community support network. The researcher integrated community resources to establish the model of “community care” by using cooperation method to enhance the relationship among the family, school and community. To sum up, this study suggests that the practitioners of community work should develop a cooperative team to set up the action strategy through the process of participating and discussing together, and furthermore operate the mechanism of support each other instantly in order to solve the problems in the practice.
