Abstract
In Japanese elementary schools, the number of children with different mother tongues are increasing. Therefore the teachers are searching effective methods of adapting to the changes in student population in their classes. Previously, Japanese schools attached to the Japan Embassy have faced the situation in their classes. However there aren’t enough teaching methods because the actual conditions among children vary widely. Therefore, I want to suggest a teaching method that is effective for dealing with a class with significant differences in the Japanese levels of the learning materials. In the class, linguistic activities are divided into three steps, I observed the conversations of children outside their classes, then I attempt to discover the ways of their thinking and searched for an effective method. The observations show children’s motivation to communication appeared to have an impact on their future Japanese acquisition.
