Abstract
A learner-centered teaching method to master vocabulary through peer learning has been applied to an intermediate Japanese language class. First, a learner writes some words on A3 size paper about one topic as a mind-map. Then the learner shows the vocabulary-map to his peer learner and they teach each other their vocabulary-maps. They are also shown an example of a vocabulary map by the teacher as a reference. Finally, they decide on a common social issue as a topic from the common vocabulary they found. After deciding on the theme, the learners write essays or debate for practice and discourse.
