Dyscalculia
[ send me this paper ]
This is an 8 page paper on the learning disability dyscalculia. Dyscalculia is a developmental mathematical learning disability which is often considered part of or the same as dyslexia, the developmental reading and writing disability. While dyslexia has been known to cause some dysfunction in the understanding of mathematical elements, dyscalculia is much more complex in that it also includes over fifty different distinct classes of mathematical disabilities which include elements of confusion of abstract and strategic thought, an inability to properly construct time, schedules, or visual representations of places and directions as well as a person’s inability to conduct many tasks necessary in the running of a household such as financial planning, balancing checkbooks and credit cards, and may also include instances of people being habitually late, lost or unable to locate objects among other factors. Researchers in special education feel that the disability of dyscalculia is not being addressed in the educational systems because largely Americans are more accepting of being mathematically deficient but find that being deficient in reading and writing is not socially acceptable. Bibliography lists 5 sources.
