This study shows an example of re-construction of the model lesson which is developed at an attached school by a teacher working in a public school. In this study, the practice is a lesson of social studies in Junior High School. As a result, 83.4% of the students achieved the goal of the class. In this case, the lesson model developed in the attached school has been successfully re-constructed. Previous studies had pointed out the influence of teachers’beliefs in educational practices. However, in this case, it was suggested that the teacher’s view of learning activity and students had a great influence on the re-construction. The future task is to clarify the process of re-constructed of the goal.
