Aim and Background: Executive functions are the most important factors that influence students’ mathematics disorders. With the technological advances in the field of education it is possible to use a computer training program to evaluate and treat this disorder. Method and Materials: In this quasi-experimental research we selected 10 female elementary students of learning disorder centers in Tehran with mathematics disorder, and 10 normal students. The two groups were matched in age and intelligence. We tested all of the students with Key Math and executive functions tests. Students with mathematics disorders received the working memory training for 20 sessions in 7 weeks. Samples of these researches were retested using executive functions test. In order to compare the executive functions in students with and without mathematic disorders Student’s t-test was used to analyse data. Findings: There were differences between executive functions in students with and without mathematics disorder. Moreover, working memory training had a significant effect on the executive function of students with mathematics disorder. There were more significant difference in average in the math disorder group in comparison to the control group. In addition, there was a significant difference in effect of executive functions pre- and post-intervention, and in follow-up. Conclusions: The results of the current study showed that the working memory computer assisted program caused improvements in executive functions of students with mathematics disorders.
