The effect of instructional multimedia on communicational skills learning of autism students

Background: This research aimed to estimate the effect of instructional multimedia on communicational skills learning of autism students at 3rd grade elementary school in Tehran. Methods: The method of this research was quasi- experimental and population was all the autism students at 3rd grade elementary school in Tehran.16 students were chosen by accessible sampling and they were randomly divided into control and experimental groups. The communicational skills questionnaires was made by researcher which had 5 components. Experimental group was trained with researcher-made multimedia software and control group was kept away from independent variable. In order to estimate the changes, at first a pre-test was performed on both groups. After pre-test, the experimental group was exposed at independent variable (Instructional multimedia).and post-test was performed on both groups. For analyzing the data, the statistical methods at two levels of descriptive (central and scattering) and inferential (multivariate analysis of covariance) were used.Results: In this study, the analysis of covariance was used to evaluate assumptions and since there were established homogeneity of slope of regression and homogeneity of error variances, the results of the test of univariate and multivariate covariance analysis showed that enriched learning in multimedia environment effected on enhancing student's communicative skills that have.  autism disorders (p≥ 0/001). Conclusion: in line with other studies, the results of this study showed positive function of using electronic content of interaction- based and Multimedia Education system on learning communication skills of students with autism disorders'.
