Then, intervention was administered through teaching by using computer games in the experimental group. By using the Andre Ray and Kim visual memory test karad, and in the manner of Pre-test and after-test pseudo-experimental plan with the control group, the effects of computer games have been studied and the results have been analyzed with the method of Covariance Analytical Statistics. The analysis of the results indicated that the computer games have a meaningful positive effect on the dyslexic students.
