Objective: One of the most important learning disabilities is spelling learning disability which is accompanied by memory problems and Visual Perception. To improve the spelling performance of students with learning disabilities a certain of strategies were used to strengthen working memory and visual perception.
Methods: This study was a Quasi-experimental research with pretest-posttest design and control group. The statistical population included 123 students from third grade elementary school in Kermanshah city. The sample group consisted of 24 students who were selected and randomly divided into two groups, experimental (n=12) and control (n=12) groups. In order for a differential diagnosis of spelling learning disability from other disorders, Wechsler Intelligence Scale for Children (fourth Edition) was evaluated. Strategies to strengthen working memory and visual perception during 10 sessions were applied to the experimental group while the control group did not receive any training. 
Results: Results of covariance analysis model showed that ,with control of pre-test effect there is a significant difference between the experimental and control group in post-test (p<0.01)and the mean scores of spelling in experimental group in post-test stage has been increased in comparison of the pre-test and control group.  
Conclusion: The results of this study indicated that strategies to strengthen the working memory and visual perception, improves the performance of students with disabilities in the spelling both in total score and in subscales of the test (picture writing, error detection, diagnosis intensifies on the desired letter, correction finding, word coinage, word completion, recognition of homophonic letters, placement of full stop, punctuations and writing the educational and text spelling).
