The aim of this study was to design a questionnaire for learning disability (parent-child assessment) in preschool students. The Learning Disability Questionnaire consists of two parts: perception (visual and auditory). The content validity of the questionnaire was confirmed by psychology professors and then it was performed on a sample of 294 preschool students. The questions were analyzed by appropriate statistical methods and the validity and reliability of the questionnaire were determined. According to the calculations, the internal consistency coefficient in the auditory perception factor is 0.83, and the visual is 0.86. An independent t-test was used to evaluate the differential validity. The results showed that there was a significant difference between the scores of deficient and normal students. We used the learning disability test to assess concurrent validity. The results showed that there is a significant relationship between the two variables of the Learning Disability Questionnaire (Parent Assessment of Preschool Child) and the Special Learning Disability Test for Children. Depending on the obtained reliability and validity, this test can be used as a tool to assess and detect early learning disabilities of preschool students.

Objective: The aim of this research was to examine the impact of instructional multimedia on learning and retention of mathematics of fourth grade educable mentally retarded girl students of elementary schools in the Arak city.
Method: The quasi-experimental research method has been used. The statistical population include all fourth grade educable mentally retarded students of elementary schools in the Arak city and the sample included all the statistical population , that were randomly assigned into an experimental and a control group. While the experimental group received three training sessions with a researcher made instructional multimedia software, the control group was trained with the conventional method without using the multimedia. In order to study the probable resulting changes, first, a pre-test was applied on both groups. After running the test, the experimental group was exposed to the independent variable. Both groups underwent the post test, and a second post test was performed to measure the retention after a two weeks time.
Results: The statistical analysis was descriptive and inferential statistics. Findings showed that learning and retention rates of students in the experimental group as compared with the control group were significantly increased.
Conclusion and recommendations: Overall, the results of the research show the excellence of learning and retention rates of students who had received training through multimedia software. Based on the results, it can be recommended that instructional multimedia can be useful in teaching and learning of mathematics for this group of students.
