Dyscalculia or processing weakness is a learning disorder in mathematics. She’s felt a lack of understanding of numbers as well as a lack of numeracy. Compared to the reading spelling (dyslexia/LRS) the phenomenon of computing weakness, although now for about twenty years has explored, so far only to a limited extent found its way into the public consciousness. Up to five per cent of all primary school pupils are considered, according to recent studies massively \”computing weak\”. This means first of all: despite educational support measures, despite still so time-consuming practicing at home not in the position to gain even the basic mathematical knowledge and skills, are. Affected students show longer weaker performance than in other subjects in mathematical foundations (quantities understanding number term, basic arithmetic operations, decimal positional notation). The World Health Organization (WHO) leads \”circumscribed in the ICD-10 (1) in section dyscalculia Developmental of school skills on (2).
In subsection F81. 2 is to find the definition of the calculation error: \”this disorder consists in a circumscribed drawback of numeracy, which is explained not only by a general reduction in intelligence or an inadequate schooling. \”The deficit concerns above all the mastery of basic computing skills, such as addition, subtraction, multiplication and Division, less the higher mathematical skills that are needed for algebra, trigonometry, geometry or differential and integral calculus.\” Behind the word dyscalculia, an often many years of torment with the number stands for those affected. overwhelmed parents do all the time: the children may not understand what number is greater and which is less. \”Simple tasks such as\” what is more: eight elephants or eight ants? \”the children answer with: the elephants of course!\” You write digits reversed and confuse calculus. A difference between multiply and Divide is often not recognized. Computer children very often require counting AIDS: fingers, toes, pins, and if everything is not enough, imagine air fingers.
