The current community college education should seek a new teaching method to educate manpower which is demanded in the knowledge-based society of the future. In an increased demand for this trend, Community Based Learning(CBL) came to the fore. For CBL to be set up as a practical teaching-learning method, there is a need for establishing theoretical system of CBL. Therefore, this study carried out the theoretical analysis of CBL by investigating its concept, theoretical backgrounds, basic assumptions, characteristics, components, and the differences between and existing teaching-learning methods. The main focus of the interest in this study was shown through the following three aspects. First, experiential learning, constructivism, and cognitivism which are the theoretical bases of CBL were described. Second, concepts and components of local society experimental study have been identified, and reorganized the applying method for the community college. Finally, expected performances and effects were analysed in discussion on the educational value of CBL. And some pedagogical implications of CBL related to the practical education were suggested focusing on the shift to the learner-centered instruction, the contribution to vocational education accountability of community college, and the good teaching between teacher and students.
