Abstract
The purpose of this study was to investigate the effectiveness of perceptual enrichment on working memory and mathematical performance of students with special learning disabilities in mathematics. The method of this study was a semi-experimental pre-test/post-test with control and experimental groups. The statistical population was included all students with special learning disabilities in mathematics in the fourth to sixth grades in Isfahan city, among whom 28 of them were selected through convenience sampling and were divided into the experimental and control group (14 participants each group). To collect data, Wechsler intelligence scale for children–Fourth Edition (WISC-IV), Keymath Test and N-back Working Memory Test were used, and the experimental group participated in 10 sessions of 45-60 minutes (twice a week) duration in perceptual enrichment intervention. The data was analyzed by using univariate and multivariate analysis of covariance tests. The results indicated the effectiveness of perceptual enrichment on improving working memory (p<0.001) and math performance (p<0.001) of the experimental group students. The results of this study showed that perceptual enrichment can be effective in improving working memory and mathematical performance of students with special learning disabilities in mathematics.
