When two of my undergraduate university education students, future teachers, invited me to visit their teaching practicum classroom to observe a first-grade boy with "

math disability," I immediately accepted their invitation.

Challenges in identifying target skills for

math disability screening and intervention.

Swanson and German [25] in a meta-analysis on the literatures concerning mathematics learning disability stated that those who have

math disability compared to normal ones have significantly weaker performance on verbal working memory, working visual-spatial memory and long term memory.

For a child with a

math disability, what is the relative gain of a summer spent with a math tutor instead of friends?

It is estimated that between 5-8% of all school age children have a

math disability (MD) as determined by the dual discrepancy model (Geary, 2003).

Participants with ADHD or comorbid reading disabilities (Jordan, Kaplan, & Hanich, 2002) were not included in Studies 1-3, as the performance of such participants is substantially different from that of children classified exclusively with a

math disability (Seidman, Biederman, Monuteaux, Doyle, & Faraone, 2001).

While the definition of learning disabilities has been the subject of controversy for decades, the current federal classification system identifies three specific areas of deficit: reading, written language, and mathematics and maintains the presumption that the disabilities are a result of a central nervous system dysfunction, in contrast to the expansive literature base in language arts, research on

math disability is far less developed and continues to lack an empirically-based identification of core deficits.

The focus of this issue of "NetNews" is dyscalculia, or

math disability. Most of the attention over the years has been on reading and writing difficulties, thus leading to the belief that math difficulties are not very common or serious.

In contrast,

math disability researchers are still working to define math learning disability and to identify underlying cognitive or genetic attributes.

If a student with a

math disability, for instance, suddenly shouts out in class, that student should be accorded normal disciplinary treatment, because the disruptive behavior isn't linked to the disability.

Math Disability Classification Criteria" subheading.
