The interpretive communities is an organism of reader. The members of it, who are the interpretive subjects, own idea of community, public idea and interpretive strategies jointly. The interpretive subjects construct interpretive idea by using the public idea and interpretive strategies based on idea of community. The interpretive subjects interact each other for holding the interpretive idea in association, which is the joint-subjectivity. The interpretive subjects form the interpretive communities by constructing the joint-subjectivity. The now reading instruction is conducted relying on views of the centered-reader which based on liberalism. It claims that the reader must constructs the unique idea, which is originative and private idea of reader, in reading. The reader can't communicate each other with the unique idea. Because of it is isolated idea in one reader. The interpretive communities demand to reader to interact each other for idea. It based on communitarianism. If the reading educator choose this view, the reader constructs common idea for community. The reading education could be changed renewedly. The one method of refreshing reading instruction is to accept the conception of the interpretive communities. In interpretive communities, the interpretive subject constructs joint-subjectivity by using the public idea and the interpretive strategy. The reading teacher must study about reader communities.
