The purpose of the present research is to investigate the effectiveness of working memory training software on attention functions of students with mathematics learning disabilities. The methodology is experimental, with pre-test and post-test with a control group and the statistical population included male and female students with learning disabilities in second to sixth elementary grades with mathematic learning disability at schools in the Central Province between 1392 to 1393. Thirty students were selected by cluster random sampling and randomly assigned to experimental and control groups. The instrument used in this research were Demographic questionnaire, working memory training software, Stroop Test software, the Wechsler Intelligence Scale for children four, was Math Test (Kenoly, 1988). The research data were analyzed through multivariate analysis of covariance (MANCOVA). The results showed that after performing working memory training software in the test group, the subscale of function in the Stroop test between experimental and control groups improved significantly. The results showed that using the software working memory is used to improve attention functions of students mathematics learning disabilities and it can be used as an effective method.
