Journal Article 2023 10 10 Mathematics learning disorder is associated with impaired cognitive function. The purpose of this research was to investigate the effectiveness of multisensory instruction on processing speed, working memory and visual-motor coordination of children with mathematics learning disorder. The present research was a quasi-experimental study with pretest, posttest and control group design. The statistical population of the study included all children with mathematics learning disorders from the second to the fifth grade who referred to learning disorder centers in Rasht city in the academic year of 2022-2023. The sample size purposefully included 30 children who received the diagnosis of mathematical learning disorder, who were randomly assigned to two groups of 15 people (experimental and control groups). The research tools include the fourth version of the Wechsler Children's Intelligence Scale (2003) to evaluate processing speed and working memory, the Iran Kemet diagnostic test (1988), the Bandar Gestalt visual-motor skills test (1938) and the Raven progressive matrices test (1936). The data were analyzed using descriptive (mean and standard deviation) and inferential (analysis of covariance) statistics. The findings of the research showed that multisensory Instruction had a significant effect on processing speed and working memory and visual-motor coordination of mathematics learning disorder. Therefore, multisensory instruction can be used to reduce the problems of children with mathematics learning disorder. Mathematics learning disorder is associated with impaired cognitive function.
