Dysgraphia is a specific learning disability that affects how easily children acquire written language and how well they use written language to express their thoughts.
Dysgraphia is a Greek word. The base word graph refers both to the hand’s function in writing and to the letters formed by the hand. The prefix dys indicates that there is impairment. Graph refers to producing letter forms by hand. The suffix ia refers to having a condition. Thus, dysgraphia is the condition of impaired letter writing by hand, that is, disabled handwriting and sometimes spelling. Impaired handwriting can interfere with learning to spell words in writing. Occasionally, but not very often, children have just spelling problems and not handwriting or reading problems.
What Causes Dysgraphia?
Research to date has shown orthographic coding in working memory is related to handwriting. Orthographic coding refers to the ability to store unfamiliar written words in working memory while the letters in the word are analyzed during word learning or the ability to create permanent memory of written words linked to their pronunciation and meaning. Children with dysgraphia do not have primary developmental motor disorder, another cause of poor handwriting, but they may have difficulty planning sequential finger movements such as the touching of the thumb to successive fingers on the same hand.
Does Dysgraphia Occur Alone?
Children with impaired handwriting may also have attention-deficit disorder (ADHD)—inattentive, hyperactive, or combined inattentive and hyperactive subtypes. Children with this kind of dysgraphia may respond to a combination of explicit handwriting instruction plus stimulant medication, but appropriate diagnosis of ADHD by a qualified professional and monitoring of response to both instruction and medication are needed.
Dysgraphia may occur alone or with dyslexia (impaired reading disability) or with oral and written language learning disability (OWL LD, also referred to as selective language impairment, SLI).
Dyslexia is a disorder that includes poor word reading, word decoding, oral reading fluency, and spelling. Children with dyslexia may have impaired orthographic and phonological coding and rapid automatic naming and switching. Phonological coding refers to coding sounds in spoken words in working memory. Phonological coding is necessary for developing phonological awareness—analyzing the sounds in spoken words that correspond to alphabet letters. If children have both dysgraphia and dyslexia, they may also have difficulty in planning sequential finger movements.
OWL LD (SLI) are disorders of language (morphology—word parts that mark meaning and grammar; syntax—structures for ordering words and understanding word functions; finding words in memory, and/or making inferences that go beyond what is stated in text). These disorders affect spoken as well as written language. Children with these language disorders may also exhibit the same writing and reading and related disorders as children with dysgraphia or dyslexia.
Why is Diagnosis Important?
Without diagnosis, children may not receive early intervention or specialized instruction in all the relevant skills that are interfering with their learning of written language. Considering that many schools do not have systematic instructional programs in handwriting and spelling, it is important to assess whether children need explicit, systematic instruction in handwriting and spelling in addition to word reading and decoding. Many schools offer accommodations in testing and teaching to students with dysgraphia, but these students also need ongoing, explicit instruction in handwriting, spelling, and composition. It is also important to determine if a child with dysgraphia may also have dyslexia and require special help with reading or OWL LD (SLI) and need special help with oral as well as written language.
What are Ways to Improve Dysgraphia?
Initially, children with impaired handwriting benefit from activities that support learning to form letters:
- playing with clay to strengthen hand muscles;
- keeping lines within mazes to develop motor control;
- connecting dots or dashes to create complete letter forms;
- tracing letters with index finger or eraser end of pencil;
- imitating the teacher modeling sequential strokes in letter formation; and
- copying letters from models.
Subsequently, once children learn to form legible letters, they benefit from instruction that helps them develop automatic letter writing, using the following steps to practice each of the 26 letters of the alphabet in a different order daily:
- studying numbered arrow cues that provide a consistent plan for letter formation;
- covering the letter with a 3 x 5 card and imaging the letter in the mind’s eye;
- writing letters from dictation (spoken name to letter form); and
- writing letters during composing for 5 minutes on a teacher-provided topic.
Students benefit from explicit instruction in spelling throughout K–12:
- initially in high frequency Anglo-Saxon words;
- subsequently in coordinating the phonological, orthographic, and morphological processes relevant for the spelling of longer, more complex, less frequent words; and
- at all grade levels in the most common and important words used for the different academic domains of the curriculum.
Throughout K-12, students benefit from strategies for composing:
- planning, generating, reviewing/evaluating, and revising compositions of different genre including narrative, informational, compare and contrast, and persuasive; and
- self-regulation strategies for managing the complex executive functions involved in composing.
