A target of this research is to solve the problem of children who cause external problem behavior and pose a dilemma in themselves fundamentally. First, I built the national language department class based on the knowledge I obtained from previous study. Next, I practiced the national language department class and analyzed the result quantitatively. I then considered the tendency of the whole with regard to “child’s logic”. The importance of three points became clear as a result. (1) Target: Be aware that a motivation target, a skill target and a value target are consecutive. Establish contents by which a child will notice the logic different from own “child’s logic,”accept it and feel diversity. (2) Way: Establish a process in which the existence of various opinions is understood, common points in a point of difference are noticed, and experiences are accepted by others and others’opinions are accepted. (3) Teaching materials: Keep a moderate distance between the characters and events in stories and the child’s experience in real life.
