The purpose of the present research is to study the effects of educational multimedia in dictation and its role in improving dysgraphia in students with dictation difficulty. Research methodology is categorized as being quasi-experimental. The statistical population of the study includes students with dictation difficulty of the second grade of primary schools of Arak in the 2011-2012 academic year. The population (including 39 students) is selected through utilization of Poisson sampling procedure. From the designated sample, 20 members are selected to be put in the experiment group and the remaining 19 members are put in the control group. Clinical interview, dictation test, and Wechsler Intelligence Scale for Children-Revised (WISC-R) are utilized to distinguish students with dictation difficulty from normal-progress students in learning disability center. Dictation test for data compilation and Mann-Whitney-Wilcoxon U-Test (MWW) for data analysis are used. The findings of the study depict that the level of improvement of dysgraphia of those students who rely on educational multimedia in dictation has a positive statistical significance in comparison with those who rely on normal educational procedures (p<0.001). Therefore, educational multimedia in dictation has a positive impact in improving dysgraphia in students with dictation difficulty.
