The purpose of this study was to examine the effect on the degree of self-assertions and the change of the personal relations of children with learning disabilities through self-expression training. In this study, after appling the program for self-expression training to children with learning disabilities, we took three weeks of pre-test with ten of children with learning disabilities under the assumption that the degree of their self-assertions and the level of their personal relations would improve. And then we produced the average score and the standard deviation using data obtained from the results of applying the program for self-expression training for three months, and utilized t-testing in relation to the difference between the pre-test and post-test. The conclusion attained through this study was as follows: First, the program for self-expression training had not the effect on improving the self-assertion behaviors of children with learning disabilities. Second, the program for self-expression training had the effect on the positive change of personal relations of children with learning disabilities. The conclusion like this provides children with learning disabilities with the grounds for self-growth, and has the large significance in the guiding method for forming valuable personal relations.
