Lowenfeld is a influential scholar who affects the education of the art, his expression development feature has been still cited. But as the time changes at the same time children changes, it is difficult to adopt as it is. In case of the infants who are in pre-schematic stage, they are growing up highly fast. So it is necessary to review. Accordingly in this study one of the feature of the expression development feature of Lowenfeld, regarding Cubist expression, recently it requires consideration from accordance of the Cubist Expression Development feature of Korea's infants. From March 2005 to December 2007, through 18 times, the result of the clay expression is as follows. First, infants tend to express something they are more accustomed to than human. Second, they tend to perform the plane surface than standing work. Contrary to theory of Lowenfeld, it tends strongly to transit from entire to specific description. In the pre-paper of Park Young Ju(2004), it shows that infants who are in pre-schematic stage have the differences in the Cubist Expression as the theory of Lowenfeld has. As it is not merely considered that the child in this stage is different from the theory of Lowenfeld, hereafter I suggest that the Expression development feature should be studied soon.
