The purpose of this study was to examine the effects of rice-clay artistic activity program for self-expression improvement and aggression reduction. the data of 50 were used in the final analysis, pretest-posttest control group design was applied, and the difference between groups in self-expression and aggression was analyzed. Besides, an analysis was conducted into detailed characteristics of four participants who demonstrated a striking change during the process. What was used as analysis data included ratings of kindergarten teachers or home room teachers in school for self-expression and aggression, the observation sheet made by a professional program lecturer, video data on activity record and participants work. Analysis of covariance was carried out using SPSS 20.0. Study findings are shown below. Firstly, the results from controlling the previously measured value and analysis of covariance in order to identify the different between the control group and experimental group according to whether to attend the artistic activity program using rice-clay represented that the average of the experiment group was statistically high in voice and substantive factor among self-expression sub-factors. Secondly, the average of the experiment group was statistically low in interpersonal relationship factor among sub-factors of aggression. Through these results, we discussed the implications and the limitations of this study.
