The purpose of this study is to find out what effects the art activity has on artictulation error and attention deficit behavior. The specific problems which solutions are sought after are as follows. Problem 1. What effect does art activity has on articulation error? Problem 2. What effect does art activity has on attention deficit behavior? To find a solution to the problem above. a case study was conducted on a problem student The subject of this case study was a grade 4 student. The subject showed a serious degree of articulation error in Picture Consonant Articulation Test and Test of Language Development-Prima ry(TOLD-P) and a serious degress of attention deficit behavior in Drawing A Person Test and HTP Test. To measure the degree of correction in articulation error. Picture Consonant Articulation: TCAT and test of language development-primary(TOLD-P) was used. CTPS-48 was used to measure the attention deficit behavior. The art activity program was developed in consultation with the supervising professor taking into consideration the subject and the uniqueness of art activity. The program was 42 sessions of 50 minute session in length The result and the concIusion is as follows. First. the application of art activity program had a tremendous collection effect on articulation error Second. attention deficit behavior decreased while the art activity program was administered. Third. such correction effect was also seen in HTP and DAP The results show that articulation error or attention deficit behavior in children can be corrected and treatment using art activity seems to be the best method.
