This meta-analysis looks at the results of five studies on the use of technology for the treatment of dyscalculia in primary school age children. Results show significant positive improvement using specialized software treatment technologies for students in Grades 1-5 in various countries using four different software games. However, little is known overall about the effectiveness of technology treatments for dyscalculics, and even less is known about standardized assessments and treatment of this learning disorder in the United States. The literature researched for this dissertation did not put forth any known policies that drive assessment and treatment of dyscalculia. Future studies are needed about dyscalculia, that provide more detailed information to allow other researchers to verify their work.
