摘要：There are many study to reveal pattern of problem solving, but there is no study that reveal the development of human problem solving, especially in physics problem solving. This study aims at describing the development of problem solving pattern of school-age children. Data were obtained through a written test and interview by asking question related to daily physics problem. This study was study of the development that used the Cross-Sectional method. Subject of this study were 25 school-age children of fourth grade until twelfth grade. There were three students taken from each grade level except the twelfth grade which was only supports by onestudent. Results of this study showed that there were four patterns of problem solving of fourth grade until twelfth grade children, those were Intuitive Problem Solving, Primitive Problem Solving, Hipotetic Problem Solving, and Expert Problem Solving. This patterns showed a stage of problem solving development of school-age children. It was concluded that problem solving ability grows during the development of human.
