The purpose of this study was to investigate the effects of integrating community resources into elementary school's interdisciplinary theme-based curriculum. According to the social action approach proposed by Chen Li Hua et al (2004), a 9-week curriculum named "Walking and Reading Through the Dau Jiang Tzuen" of South Farm Elementary School (a pseudonym) was designed and implemented. The research tools included interview records, reflection journals, worksheets, meeting records, feedback forms of parents and questionnaire of satisfaction. The results showed the curriculum not only improved the interest in learning of participants and promoted the enthusiasm in teaching of teachers, but also had positive influence on the ability in problem-solving of the students. Besides, over 70% of students were satisfied with the curriculum. Regrettably, the goal of the curriculum to lead students to show much concern about their hometown did not achieve effectively. Thus some proposals were made for developing the theme-based curriculum in the future.
