The research is investigating the theory of Cognitive Development for children, and its application onto the importance of children dance. As a dancing teacher myself, the researcher understood that it’s necessary to give different teaching style and lecture contents for children of different ages. If cooperate with Theory of Cognitive Development, it’s foreseen to have the children growing healthily and learning happily. The research is mainly using Jean Paul Piaget and Jerome Seymour Bruner’s cognitive development as the tools. Through documental analysis, the goal is to identify the connection between these two theories and children dancing, as well as the appliance on dancing education. If the teachers have good understanding on the behaviors for different children cognitive developments and the corresponding behavior characteristics, then they will have enough knowledge background to choose the suitable dancing technique for different ages. The teacher will be able to put the children’s instinct and requirements into consideration and design a sequential lesson that coordinates children cognitive developments and theory, thus accomplished “Adaptive Instruction”. Not only the teacher can monitor children’s cognitive development and learning outcome, but also can provide the children a chance to explore, and satisfy the curiosity. The ultimate goal is to stimulate the body function and improve the motive to learn for the children.
