There are many researches to improve elementary children's positive attitudes toward children with disabilities with various independent variables such as acture experiences like children with disabilities, video materials related with children with disabilities, and reading essays which are written by children with disabilities. However, most researchers have studied to illustrate the effects of the only one independent variable to improve the elementary children's attitudes toward children with disabilities. The purpose of this study was to compare the effects which independent variable was influenced to improve more elementary children's positive attitudes toward children with disabilities. The independent variables for this study were acture experiences like children with disabilities, video materials related with children with disabilities, and reading essays which are written by children with disabilities. One hundred twenty five children who were attending the fifth grade were participated. The children were divided into three experimental groups and one control group divided. Pre- and post-test were utilized with a thirty-questions questionnaire after five experimental sessions. The results of this study were that: (a) the two independent variables, acture experiences like children with disabilities and reading essays which is written by children with disabilities, were not related with the children's positive attitudes toward children with disabilities statistically; (b) the independent variable, video materials related with children with disabilities, was related to improve the children's positive attitudes toward children with disabilities. This study concluded that video materials related with children with disabilities were a excellent strategy to improve the children's positive attitudes toward children with disabilities.
