Learning disabilities: dyslexia, dyscalculia and dysgraphia Learning disabilities are problems that affect the brain's ability to receive, process, analyse, or store information. Learning disability does not have anything to do with a person's intelligence. There are many kinds of learning disabilities and most students affected by them have more than one kind. Learning disabilities usually first show up when a person has difficulty in speaking, reading, writing, figuring out a math problem, communicating with a parent, or paying attention in class. The causes are still unknown, but there are some different theories: genetic influences, brain development and environmental impacts. Dyslexia The word dyslexia comes from two Greek words: dys, which means abnormal or impaired, and lexis, which refers to language or words. When people with dyslexia read, they use different parts of the brain than people without dyslexia. The brains of people with dyslexia do not work efficiently during reading. They also have difficulties in recognizing short, familiar words, or to pronounce longer words. The meaning of the word is often lost and reading comprehension is poor. A student with dyslexia may get more time to complete tests, permission to record class lectures or copies of lecture notes. Dyscalculia is a brain-based condition that makes it hard to make sense of numbers and math concepts. Dyscalculia goes by many names, some public schools refer to it as a "mathematics learning disability", or doctors call it a " mathematic disorder". The most common problem is with "number sense": children cannot understand how numbers work, and how to compare and estimate quantities on a number line. Researchers do not know exactly what causes dyscalculia. But they have identified certain factors that indicate it is a brain-based condition: genes and heredity, brain, environment, brain injury. Dyscalculia tends to become more apparent as children get older. Dysgraphia is a specific learning disability that affects written expression. It is a neurological disorder that generally appears when children are learning to write. Experts are not sure what causes it , but early treatment can help prevent or reduce problems. It requires not only the ability to organize and express ideas in the mind, but also the capacity to get the muscles in the hands and fingers to form those ideas, letter by letter, on paper. Educational psychologists use a series of tests to determine if a person has this disability. There are many ways to help a person with dysgraphia. Generally, strategies fall into three categorie: Accomodation: providing alternatives to written expression; Modifications: changing expectations or tasks to minimize or avoid the area of weakness; Remediation: providing instruction for improving handwriting and writing skills. .

Dyslexia and Dyscalculia Are the Same Thing
Dyscalculia and Dyslexia Two different issues, or part of the same problem? By Tony Attwood C.Ed., B.A., M.Phil. Chairman of The Dyscalculia Group, First and Best in Education Ltd. Dyscalculia is noted as an unexpected difficulty that some people have in dealing with mathematical problems. At its simplest we may note a child whose age and intellect suggests that he or she will be able to undertake a certain range of skills, but who in effect is unable to handle maths problems that we would expect to be well within his or her grasp. As a general introduction to the topic we may note that according to the American Journal of Paediatrics in 2001 dyscalculic children have “Normal or advanced language and other skills, often good visual memory for the printed word, (and) poor mental maths ability often with difficulty in the use of money, such as balancing a chequebook, making change and tipping. Often there is a fear of money and its transactions and difficulty with maths processes (e.g. addition, subtraction, multiplication) and concepts (e.g. sequencing of numbers). There is sometimes poor retention and retrieval of concepts, or an inability to maintain a consistency in grasping maths rules, poor sense of direction, easy disorientation, as well as difficulty with reading maps, telling the time and grappling with mechanical processes, difficulty with abstract concepts of time and direction, schedules, keeping track of time and the sequence of past and future events.” These children make, “Common mistakes in working with numbers including number reversals and omissions,” (and) “May have difficulty learning musical concepts, following directions in sports that demand sequencing or rules, and keeping track of scores and players during games such as cards and board games.

This work is licensed to the public under the Creative Commons Attribution License. Dysgraphia: How It Affects A Student’s Performance and What Can Be Done About It Alyssa L. Crouch Jennifer J. Jakubecy Abstract The purpose of this study was to apply two techniques, drill activities and fine motor ac- tivities, to find whether they help improve the handwriting of a student with dysgraphia. This action research used an ABAB single subject design to find which technique worked better over an eight-week period. The results were inconclusive on which technique worked better. However, the combination of both improved the subject’s handwriting and increased his score by 50%. Therefore, this study suggests that using both techniques can help improve the problems associated with dysgraphia, especially in the area of handwrit- ing.

Brown !1 Madeline Brown Professor Veach CC ENG 1233 22 MAR 2019 Dysgraphia Introduction Envision a kindergarten student sitting in school with an assignment to copy. As she sits down, she already knows the challenge writing presents for her but does not speak up or say anything because this time probably will not be any different than when she requested help before. She has been labeled as a lazy writer and has never had the most readable handwriting. All of the other children around her finish the assignment and she inevitably she remains unable to complete the first sentence. This scene does not have to play out this way. Students in schools across the world are created uniquely with different strengths and weaknesses. Teacher to student ratio, few learning disability training resources, and confusion regarding whether a child has a legitimate learning challenge all contribute to the inability of schools to accurately detect early learning disabilities (Judd 97). Without proper training, some difficult to identify diagnoses of childhood learning and behavioral struggles include but are not limited to; Dyslexia, Autism, Dyspraxia, Attention Deficit Disorder, Dyscalculia, and Dysgraphia.

What This Means for You As a Special Educator/Service Provider
Anne Arundel County – Department of Special Education Technical Assistant Bulletin (revised July 2017) Specific Learning Disability; Including Dyslexia; Dysgraphia; Dyscalculia September 2019 Overall Emphasis and Purpose: Specific Learning Disability (SLD) is one of the 13 categories of disability recognized by the IDEA. SLD is the only disability category for which the IDEA establishes special evaluation procedures, in addition to the general procedures that are used for all students with disabilities. The definition of a SLD is “a disorder in one or more of the basic psychological processes involved in understanding, or in using language spoken or written, that may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations.” During the 2017 legislative session, a bill was passed authorizing schools to identify dyslexia, dysgraphia, or dyscalculia, as subcategories under the overarching SLD classification. What this means for you as a Special What the Special Educator/Service Educator/Service Provider: Provider needs to do if not already doing: • The identification of a SLD requires that the student • Ensure that school staff are supported in implementing exhibit a pattern of strengths and weaknesses in research and/or evidence-based intervention for any performance, achievement, or both, relative to age, student who is struggling. Progress monitoring is a key State approved grade level standards, or intellectual component of determining the effectiveness of the development, as a result of a comprehensive intervention prior to considering the possibility of a evaluation. disability under the IDEA. • A student identified with a specific learning disability, • The IEP team must consider exclusionary factors, such with or without dyslexia, dysgraphia, or dyscalculia, as a lack of appropriate education, intellectual must also exhibit educational impact and require disability, visual, hearing, or motor impairment, specialized instruction.

We considered data from 2,421 children (their level of intelligence and educational achievement in mathematics and English were recorded over several school years). We investigated the effects of gender, socio-economic status, special educational needs (other than issues related to mathematics), and whether the child spoke English as their first language on mathematics achievement. 5.7% of the sample was identified as having SLDM. Compared to earlier (DSM-IV) diagnostic criteria, the prevalence of SLDM was almost 6 times higher. A child was more than a 100 times more likely to receive a diagnosis of dyslexia than SLDM, although prevalence rates are expected to be similar.
